It appears that your Vite configuration may not be correctly serving the worker files. This can happen if the paths for the workers are not correctly set up or if there is some misconfiguration in your Vite setup.

To solve this, let's ensure that your Vite configuration is correctly handling the worker files and that the paths are correct.

Step 1: Verify Vite Configuration

Ensure that your vite.config.ts is correctly configured to serve the worker files. From the provided context, it looks mostly correct, but let's add a publicDir to ensure Vite serves the static files from the dist directory:

// vite.config.ts
import { defineConfig, Plugin } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import monacoEditorPlugin, { type IMonacoEditorOpts } from 'vite-plugin-monaco-editor';

// Access the actual function nested under default
const monacoEditorPluginDefault = ((monacoEditorPlugin as any).default) as (options: IMonacoEditorOpts) => any;

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
      publicPath: '/',
    }),
  ],
  base: '/',
  build: {
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'],
        },
      },
    },
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  publicDir: 'dist', // Ensure Vite serves static files from the dist directory
  worker: {
    format: 'es',
  },
});

Step 2: Update Worker URL Configuration

Ensure that the worker URLs are correctly set up in your MonacoEditor.tsx file. You might need to adjust the paths based on how Vite serves the worker files. Here’s a refined version of your MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

// Custom type for the imperative handle
interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const validateWorkerPath = async (url: string) => {
  try {
    const response = await fetch(url);
    if (!response.ok) {
      console.error(`Worker file not found at ${url}`);
    } else {
      const contentType = response.headers.get('Content-Type');
      if (contentType && contentType.includes('application/javascript')) {
        console.log(`Worker file found at ${url} and is a valid JavaScript file.`);
      } else {
        console.error(`Worker file at ${url} is not a JavaScript file but a ${contentType}`);
      }
    }
  } catch (error) {
    console.error(`Error fetching worker file at ${url}:`, error);
  }
};

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = "90vh" }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({
      focus: () => {
        monacoEditorRef.current?.focus();
      },
      getValue: () => {
        return monacoEditorRef.current?.getValue() || ''; // Provide a default value
      },
    }));

    useEffect(() => {
      // Define MonacoEnvironment configuration to load workers
      (window as any).MonacoEnvironment = {
        getWorkerUrl: function (_moduleId: string, label: string) {
          let workerUrl = `/` + label + `.worker.bundle.js`;
          validateWorkerPath(workerUrl);
          return workerUrl;
        },
      };

      const loadMonacoEditor = async () => {
        const { initVimMode } = await import('monaco-vim');

        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,
          });

          monacoEditorRef.current = editor;

          const statusBarContainer = document.createElement('div');
          statusBarContainer.className = 'status-node';
          document.body.appendChild(statusBarContainer);

          if (!vimModeRef.current) {
            vimModeRef.current = initVimMode(editor, statusBarContainer);
          }

          editor.onDidChangeModelContent(() => {
            if (onChange) {
              onChange(editor.getValue());
            }
          });

          const defineVimCommands = async () => {
            await new Promise<void>((resolve) => {
              const checkVim = () => {
                if ((window as any).Vim) {
                  resolve();
                } else {
                  setTimeout(checkVim, 100);
                }
              };
              checkVim();
            });

            const Vim = (window as any).Vim;
            if (Vim) {
              Vim.defineEx('w', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
              });

              Vim.defineEx('q', '', () => {
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });

              Vim.defineEx('wq', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });
            } else {
              console.error('Vim object is not available on the window');
            }
          };

          // Define Vim commands after ensuring Vim object is available
          defineVimCommands();

          return () => {
            if (vimModeRef.current) vimModeRef.current.dispose();
            editor.dispose();
            if (statusBarContainer && statusBarContainer.parentNode) {
              statusBarContainer.parentNode.removeChild(statusBarContainer);
            }
          };
        }
      };

      loadMonacoEditor();

      return () => {
        // Cleanup function
        if (vimModeRef.current) vimModeRef.current.dispose();
        if (monacoEditorRef.current) monacoEditorRef.current.dispose();
      };
    }, [initialValue, language, onChange, onSave]);

    return <div ref={editorRef} className="monaco-editor-container" style={{ height }} />;
  }
);

export default MonacoEditor;

Step 3: Ensure Worker Files are Served Correctly

Ensure that the worker files are being served correctly from the dist directory. You can do this by checking the network tab in your browser's developer tools to make sure the worker files are being loaded correctly.

Step 4: Test

After making these changes, rebuild your project and test it to see if the errors are resolved. The worker files should now be correctly served and the Monaco editor should function without issues.

The issue seems to be that the publicDir setting in your Vite configuration is pointing to dist, which is typically used as the output directory for built files, rather than for serving static assets like images.

To fix this, you should separate the directory for static assets from the build output directory. This can be done by setting the publicDir to a directory specifically for static assets, like public, and then ensuring your build output remains in dist.

Here’s how you can adjust your Vite configuration:

Step 1: Adjust Vite Configuration

Change the publicDir to a directory specifically for your static assets, such as public:

// vite.config.ts
import { defineConfig, Plugin } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import monacoEditorPlugin, { type IMonacoEditorOpts } from 'vite-plugin-monaco-editor';

// Access the actual function nested under default
const monacoEditorPluginDefault = ((monacoEditorPlugin as any).default) as (options: IMonacoEditorOpts) => any;

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
      publicPath: '/',
    }),
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'],
        },
      },
    },
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

Step 2: Move Static Assets

Ensure that your static assets (like images) are placed in the public directory. For example:

public/
  images/
    Adventurer/
      Adventurer-1.5/
        adventurer-v1.5-Sheet.png

Step 3: Update Asset References

Ensure that your code references the static assets correctly. Since Vite serves static assets from the public directory at the root URL, you should reference them as /images/Adventurer/Adventurer-1.5/adventurer-v1.5-Sheet.png.

Step 4: Rebuild and Test

Rebuild your project and test it again to ensure that the static assets are being served correctly:

yarn build
yarn preview

With these changes, your worker files should still be placed in the dist directory, and your static assets should be served correctly from the public directory.

To determine which folders are being served directly by the Vite development server and the built application, you can follow these steps:

Step 1: Verify Vite Configuration

Ensure that your vite.config.ts is correctly configured to serve static files and build output. Based on your description, it seems the build output might not be correctly accessible.

Step 2: Check the public Directory

The public directory is the default directory for static assets in Vite. Anything placed in this directory should be accessible via HTTP requests. By default, Vite will copy the contents of the public directory to the root of the build output directory (dist by default).

Ensure your public directory structure looks something like this:

public/
  images/
    Adventurer/
      Adventurer-1.5/
        adventurer-v1.5-Sheet.png

Step 3: Serve Static Assets

Ensure your Vite configuration correctly references the public directory:

// vite.config.ts
import { defineConfig, Plugin } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import monacoEditorPlugin, { type IMonacoEditorOpts } from 'vite-plugin-monaco-editor';

// Access the actual function nested under default
const monacoEditorPluginDefault = ((monacoEditorPlugin as any).default) as (options: IMonacoEditorOpts) => any;

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
      publicPath: '/',
    }),
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'],
        },
      },
    },
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

Step 4: Examine Build Output

After you run yarn build, examine the contents of the dist directory. Ensure that the images and other static assets from the public directory are correctly copied to the dist directory.

Step 5: Test Static File Access

Check if the static files are accessible by running the built application using Vite's preview feature:

yarn build
yarn preview

This will start a local server to serve the contents of the dist directory. Open your browser and navigate to the URLs of your static files to ensure they are being served correctly. For example:

http://localhost:4173/images/Adventurer/Adventurer-1.5/adventurer-v1.5-Sheet.png

Step 6: Debug Static File Serving

If the static files are still not accessible, you can add some logging or debugging statements to understand what paths are being served. You can use a simple server like serve to serve the dist directory and verify the contents:

npx serve dist

This will serve the dist directory on a local server, and you can check if the static files are accessible.

Summary

By following these steps, you can determine which directories are being served by the Vite development server and the built application. Ensuring the public directory is correctly configured and verifying the build output should help resolve the issue of inaccessible static files.

The yarn preview command is intended to serve the built application locally using Vite's built-in preview server. This helps you test the production build of your application before deploying it.

Given the issues you're facing with accessing the server on port 5173, it seems like the preview server might not be starting correctly, or there might be a configuration issue. Let's troubleshoot this step-by-step.

Step 1: Verify Build Process

First, ensure that the build process completes successfully and the dist directory contains the expected output:

yarn build

Check the contents of the dist directory to ensure your application files and static assets are present.

Step 2: Start Preview Server

Start the preview server using:

yarn preview

By default, Vite's preview server runs on port 4173, not 5173. You should be able to access your application at http://localhost:4173.

Step 3: Verify Server Output

When you run yarn preview, you should see output indicating the server has started, similar to:

vite vX.X.X dev server running at:

  > Local: http://localhost:4173/

Step 4: Check for Errors

If the preview server fails to start or you encounter errors, check your terminal for any error messages. This can provide clues about what might be wrong.

Step 5: Manually Serve the dist Directory

If you're still encountering issues, you can manually serve the dist directory using a simple HTTP server like serve:

  1. Install serve if you haven't already:

    npm install -g serve

  2. Serve the dist directory:

    serve dist

This will start a local server, typically on port 5000, and you can access your application at http://localhost:5000.

Step 6: Check Network Configuration

Ensure there are no network issues or firewalls blocking the connection to the specified port. Sometimes, security software or system settings might prevent access to certain ports.

Summary

By following these steps, you should be able to diagnose and resolve the issue with the Vite preview server. If you continue to encounter problems, please provide any error messages or additional context, and we can further assist you.

Given that npx serve dist successfully serves the files, it seems there might be an issue with how the Vite development server or the Vite preview server is configured or running. Let's clarify the server processes involved:

Development Server

When you run yarn dev or vite, you start the Vite development server. This server is intended for development purposes and runs on port 5173 by default. It serves files from the project's root directory and handles hot module replacement (HMR).

Preview Server

When you run yarn preview, Vite starts a local server to serve the built production files from the dist directory. This is useful for testing the production build locally. By default, it runs on port 4173.

Build Output

The yarn build command generates the static files for your application and places them in the dist directory.

Troubleshooting Steps

  1. Development Server: Ensure the Vite development server is running correctly.

    yarn dev

    Access your application at http://localhost:5173.

  2. Preview Server: Ensure the Vite preview server is running correctly.

    yarn build
yarn preview

    Access your application at http://localhost:4173.

  3. Check Vite Configuration: Ensure your vite.config.ts is correctly set to serve static files:

    // vite.config.ts
import { defineConfig, Plugin } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import monacoEditorPlugin, { type IMonacoEditorOpts } from 'vite-plugin-monaco-editor';

// Access the actual function nested under default
const monacoEditorPluginDefault = ((monacoEditorPlugin as any).default) as (options: IMonacoEditorOpts) => any;

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
      publicPath: '/',
    }),
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'],
        },
      },
    },
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

  4. Network Configuration: Ensure there are no network/firewall issues preventing access to the specified ports.

  5. Error Messages: Check for any error messages in the terminal or browser console that might give more context.

Summary

By following these steps, you should be able to identify which server process you are using and ensure that it is correctly serving the static assets. If the Vite development or preview server is not working as expected, you can use npx serve dist as a temporary solution to serve the build output and verify everything is working correctly.

The error indicates that the worker file editorWorkerService.worker.bundle.js is being requested but is not found, resulting in an HTML response (likely a 404 page). This file appears to be required by the Monaco Editor but is not being generated or placed in the expected location during the build process.

Steps to Resolve:

  1. Verify Worker File Generation: Ensure that all necessary Monaco Editor worker files are being generated and placed in the correct directory. The Vite configuration should specify all required workers.

  2. Update Worker Configuration: Adjust the Vite configuration to ensure all workers are correctly specified and generated. Here's how you can verify and possibly add missing workers:

// vite.config.ts
import { defineConfig, Plugin } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import monacoEditorPlugin, { type IMonacoEditorOpts } from 'vite-plugin-monaco-editor';

// Access the actual function nested under default
const monacoEditorPluginDefault = ((monacoEditorPlugin as any).default) as (options: IMonacoEditorOpts) => any;

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
      publicPath: '/',
    }),
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'],
        },
      },
    },
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});
  1. Check for Missing Worker Files: Run the build command and verify the output directory contains all necessary worker files.
yarn build
ls dist

Ensure files like editor.worker.bundle.js, json.worker.bundle.js, html.worker.bundle.js, css.worker.bundle.js, and ts.worker.bundle.js are present.

  1. Update Monaco Environment Configuration: Ensure the getWorkerUrl function correctly maps to existing worker files.

        console.log(`Worker file found at ${url} and is a valid JavaScript file.`);
      } else {
        console.error(`Worker file at ${url} is not a JavaScript file but a ${contentType}`);
      }

            if (onChange) {
              onChange(editor.getValue());
            }
          });

          const defineVimCommands = async () => {
            await new Promise<void>((resolve) => {
              const checkVim = () => {

The issue seems to be that the editor.worker.bundle.js file is missing from your dist directory. This is likely because it wasn't properly generated or included in the build process.

Let's address this by ensuring that all necessary worker files for Monaco Editor are properly configured and generated.

Step 1: Verify Worker Configuration

Ensure that all required worker files are listed in the Vite configuration. Specifically, check for the editor.worker.bundle.js file:

// vite.config.ts
import { defineConfig, Plugin } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import monacoEditorPlugin, { type IMonacoEditorOpts } from 'vite-plugin-monaco-editor';

// Access the actual function nested under default
const monacoEditorPluginDefault = ((monacoEditorPlugin as any).default) as (options: IMonacoEditorOpts) => any;

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
      publicPath: '/',
    }),
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'], // Ensure this is included
        },
      },
    },
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

Step 2: Ensure Correct Worker URL Mapping

Make sure the getWorkerUrl function in your MonacoEditor component maps the editor worker correctly:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const validateWorkerPath = async (url: string) => {
  try {
    const response = await fetch(url);
    if (!response.ok) {
      console.error(`Worker file not found at ${url}`);
    } else {
      const contentType = response.headers.get('Content-Type');
      if (contentType && contentType.includes('application/javascript')) {
        console.log(`Worker file found at ${url} and is a valid JavaScript file.`);
      } else {
        console.error(`Worker file at ${url} is not a JavaScript file but a ${contentType}`);
      }
    }
  } catch (error) {
    console.error(`Error fetching worker file at ${url}:`, error);
  }
};

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = "90vh" }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({
      focus: () => {
        monacoEditorRef.current?.focus();
      },
      getValue: () => {
        return monacoEditorRef.current?.getValue() || ''; // Provide a default value
      },
    }));

    useEffect(() => {
      (window as any).MonacoEnvironment = {
        getWorkerUrl: function (_moduleId: string, label: string) {
          let workerUrl = '/editor.worker.bundle.js';
          if (label === 'json') {
            workerUrl = '/json.worker.bundle.js';
          } else if (label === 'css') {
            workerUrl = '/css.worker.bundle.js';
          } else if (label === 'html') {
            workerUrl = '/html.worker.bundle.js';
          } else if (label === 'typescript' || label === 'javascript') {
            workerUrl = '/ts.worker.bundle.js';
          }
          validateWorkerPath(workerUrl);
          return workerUrl;
        },
      };

      const loadMonacoEditor = async () => {
        const { initVimMode } = await import('monaco-vim');

        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,
          });

          monacoEditorRef.current = editor;

          const statusBarContainer = document.createElement('div');
          statusBarContainer.className = 'status-node';
          document.body.appendChild(statusBarContainer);

          if (!vimModeRef.current) {
            vimModeRef.current = initVimMode(editor, statusBarContainer);
          }

          editor.onDidChangeModelContent(() => {
            if (onChange) {
              onChange(editor.getValue());
            }
          });

          const defineVimCommands = async () => {
            await new Promise<void>((resolve) => {
              const checkVim = () => {
                if ((window as any).Vim) {
                  resolve();
                } else {
                  setTimeout(checkVim, 100);
                }
              };
              checkVim();
            });

            const Vim = (window as any).Vim;
            if (Vim) {
              Vim.defineEx('w', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
              });

              Vim.defineEx('q', '', () => {
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });

              Vim.defineEx('wq', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });
            } else {
              console.error('Vim object is not available on the window');
            }
          };

          defineVimCommands();

          return () => {
            if (vimModeRef.current) vimModeRef.current.dispose();
            editor.dispose();
            if (statusBarContainer && statusBarContainer.parentNode) {
              statusBarContainer.parentNode.removeChild(statusBarContainer);
            }
          };
        }
      };

      loadMonacoEditor();

      return () => {
        if (vimModeRef.current) vimModeRef.current.dispose();
        if (monacoEditorRef.current) monacoEditorRef.current.dispose();
      };
    }, [initialValue, language, onChange, onSave]);

    return <div ref={editorRef} className="monaco-editor-container" style={{ height }} />;
  }
);

export default MonacoEditor;

Step 3: Rebuild and Test

Rebuild your project and verify the presence of the worker files:

yarn build
ls dist

Ensure that editor.worker.bundle.js is present in the dist directory.

Step 4: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser:

http://localhost:4173/editor.worker.bundle.js
http://localhost:4173/html.worker.bundle.js

Summary

By ensuring that all necessary worker files are specified and correctly mapped in the MonacoEnvironment configuration, you should be able to resolve the issue of missing or incorrectly served worker files. If editor.worker.bundle.js is still missing, double-check the build configuration and worker file names in the Vite configuration.

It seems the editor.worker.bundle.js file is not being generated during the build process. This could be due to a misconfiguration or an issue with the vite-plugin-monaco-editor plugin.

Step 1: Ensure Correct Configuration

Double-check that the monacoEditorPlugin is correctly configured to include the editor worker:

// vite.config.ts
import { defineConfig, Plugin } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import monacoEditorPlugin, { type IMonacoEditorOpts } from 'vite-plugin-monaco-editor';

// Access the actual function nested under default
const monacoEditorPluginDefault = ((monacoEditorPlugin as any).default) as (options: IMonacoEditorOpts) => any;

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({
      languageWorkers: ['typescript', 'json', 'html', 'css', 'editor'], // Include 'editor'
      publicPath: '/',
    }),
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'], // Ensure this is included
        },
      },
    },
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

Step 2: Verify Plugin Version

Ensure you are using a compatible version of vite-plugin-monaco-editor. Sometimes plugins may have bugs or missing features in certain versions. Update the plugin if necessary:

yarn add vite-plugin-monaco-editor@latest

Step 3: Check Monaco Editor Import

Ensure that the import and usage of Monaco Editor in your code are correct. Sometimes, improper imports can lead to missing worker files:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const validateWorkerPath = async (url: string) => {
  try {
    const response = await fetch(url);
    if (!response.ok) {
      console.error(`Worker file not found at ${url}`);
    } else {
      const contentType = response.headers.get('Content-Type');
      if (contentType && contentType.includes('application/javascript')) {
        console.log(`Worker file found at ${url} and is a valid JavaScript file.`);
      } else {
        console.error(`Worker file at ${url} is not a JavaScript file but a ${contentType}`);
      }
    }
  } catch (error) {
    console.error(`Error fetching worker file at ${url}:`, error);
  }
};

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = "90vh" }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({
      focus: () => {
        monacoEditorRef.current?.focus();
      },
      getValue: () => {
        return monacoEditorRef.current?.getValue() || ''; // Provide a default value
      },
    }));

    useEffect(() => {
      (window as any).MonacoEnvironment = {
        getWorkerUrl: function (_moduleId: string, label: string) {
          let workerUrl = '/editor.worker.bundle.js';
          if (label === 'json') {
            workerUrl = '/json.worker.bundle.js';
          } else if (label === 'css') {
            workerUrl = '/css.worker.bundle.js';
          } else if (label === 'html') {
            workerUrl = '/html.worker.bundle.js';
          } else if (label === 'typescript' || label === 'javascript') {
            workerUrl = '/ts.worker.bundle.js';
          }
          validateWorkerPath(workerUrl);
          return workerUrl;
        },
      };

      const loadMonacoEditor = async () => {
        const { initVimMode } = await import('monaco-vim');

        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,
          });

          monacoEditorRef.current = editor;

          const statusBarContainer = document.createElement('div');
          statusBarContainer.className = 'status-node';
          document.body.appendChild(statusBarContainer);

          if (!vimModeRef.current) {
            vimModeRef.current = initVimMode(editor, statusBarContainer);
          }

          editor.onDidChangeModelContent(() => {
            if (onChange) {
              onChange(editor.getValue());
            }
          });

          const defineVimCommands = async () => {
            await new Promise<void>((resolve) => {
              const checkVim = () => {
                if ((window as any).Vim) {
                  resolve();
                } else {
                  setTimeout(checkVim, 100);
                }
              };
              checkVim();
            });

            const Vim = (window as any).Vim;
            if (Vim) {
              Vim.defineEx('w', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
              });

              Vim.defineEx('q', '', () => {
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });

              Vim.defineEx('wq', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });
            } else {
              console.error('Vim object is not available on the window');
            }
          };

          defineVimCommands();

          return () => {
            if (vimModeRef.current) vimModeRef.current.dispose();
            editor.dispose();
            if (statusBarContainer && statusBarContainer.parentNode) {
              statusBarContainer.parentNode.removeChild(statusBarContainer);
            }
          };
        }
      };

      loadMonacoEditor();

      return () => {
        if (vimModeRef.current) vimModeRef.current.dispose();
        if (monacoEditorRef.current) monacoEditorRef.current.dispose();
      };
    }, [initialValue, language, onChange, onSave]);

    return <div ref={editorRef} className="monaco-editor-container" style={{ height }} />;
  }
);

export default MonacoEditor;

Step 4: Rebuild and Test

Rebuild your project and ensure the editor.worker.bundle.js is generated:

yarn build
ls dist

Step 5: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser:

http://localhost:4173/editor.worker.bundle.js
http://localhost:4173/html.worker.bundle.js

Summary

By ensuring that the editor.worker is included in the Vite configuration and that your Monaco Editor setup is correct, you should be able to resolve the issue of the missing editor.worker.bundle.js file. If the problem persists, consider checking for issues or updates in the vite-plugin-monaco-editor plugin's GitHub repository or documentation.

The error indicates that the vite-plugin-monaco-editor plugin is encountering an issue during the build process, specifically when attempting to read the label property.

This might indicate a problem with the current version of the plugin or a misconfiguration. Let's address this by ensuring your configuration is correct and trying a different approach to ensure the editor worker is included.

Step 1: Use a Custom Monaco Editor Setup

Instead of relying on the vite-plugin-monaco-editor, you can manually configure Monaco Editor workers. This approach gives you more control over the configuration.

Install Required Dependencies

Ensure you have the necessary Monaco Editor dependencies installed:

yarn add monaco-editor

Update Vite Configuration

Update your vite.config.ts to manually include the Monaco Editor workers:

// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';

export default defineConfig({
  plugins: [react()],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'],
        },
      },
    },
  },
  resolve: {
    alias: {
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

Update Monaco Editor Component

Modify your MonacoEditor.tsx to manually configure the worker URLs:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {

interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const validateWorkerPath = async (url: string) => {
  try {
    const response = await fetch(url);
    if (!response.ok) {
      console.error(`Worker file not found at ${url}`);
    } else {
      const contentType = response.headers.get('Content-Type');
      if (contentType && contentType.includes('application/javascript')) {
        console.log(`Worker file found at ${url} and is a valid JavaScript file.`);
      } else {
        console.error(`Worker file at ${url} is not a JavaScript file but a ${contentType}`);
      }
    }
  } catch (error) {
    console.error(`Error fetching worker file at ${url}:`, error);
  }
};

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = "90vh" }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({
      focus: () => {
        monacoEditorRef.current?.focus();
      },
      getValue: () => {
        return monacoEditorRef.current?.getValue() || ''; // Provide a default value
      },
    }));

    useEffect(() => {
      (window as any).MonacoEnvironment = {
        getWorkerUrl: function (_moduleId: string, label: string) {
          let workerUrl = '/editor.worker.bundle.js';

          } else if (label === 'css') {

          } else if (label === 'html') {
            workerUrl = '/html.worker.bundle.js';
          } else if (label === 'typescript' || label === 'javascript') {
            workerUrl = '/ts.worker.bundle.js';
          }
          validateWorkerPath(workerUrl);
          return workerUrl;
        },
      };

      const loadMonacoEditor = async () => {
        const { initVimMode } = await import('monaco-vim');

        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',

          if (!vimModeRef.current) {
            vimModeRef.current = initVimMode(editor, statusBarContainer);
          }

          editor.onDidChangeModelContent(() => {
            if (onChange) {
              onChange(editor.getValue());
            }
          });

          const defineVimCommands = async () => {
            await new Promise<void>((resolve) => {
              const checkVim = () => {
                if ((window as any).Vim) {
                  resolve();
                } else {
                  setTimeout(checkVim, 100);
                }
              };
              checkVim();
            });

            const Vim = (window as any).Vim;
            if (Vim) {
              Vim.defineEx('w', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
              });

              Vim.defineEx('q', '', () => {
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });

              Vim.defineEx('wq', '', () => {

                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });
            } else {
              console.error('Vim object is not available on the window');
            }
          };

          defineVimCommands();

          return () => {

export default MonacoEditor;

Step 2: Rebuild and Test

Rebuild your project and ensure all worker files, including editor.worker.bundle.js, are generated:

yarn build
ls dist

Step 3: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser:

http://localhost:4173/editor.worker.bundle.js
http://localhost:4173/html.worker.bundle.js

Summary

By manually configuring the Monaco Editor workers and ensuring they are correctly included in the build process, you should resolve the issue of the missing editor.worker.bundle.js file. If the problem persists, consider checking for issues or updates in the vite-plugin-monaco-editor plugin's GitHub repository or documentation.

It seems that the workers are still not being generated. Let's take a different approach by manually copying the worker files to your dist directory during the build process.

Step 1: Install vite-plugin-copy

We'll use vite-plugin-copy to copy the worker files to the dist directory after the build process.

First, install the plugin:

yarn add vite-plugin-copy -D

Step 2: Update vite.config.ts

Update your vite.config.ts to use vite-plugin-copy to copy the worker files:

// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import { viteStaticCopy } from 'vite-plugin-static-copy';

export default defineConfig({
  plugins: [
    react(),
    viteStaticCopy({
      targets: [
        {
          src: 'node_modules/monaco-editor/esm/vs/editor/editor.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/json/json.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/css/css.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/html/html.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/typescript/ts.worker.js',
          dest: '.'
        }
      ]
    })
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext'
  },
  resolve: {
    alias: {
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

Step 3: Update Worker URL Configuration

Update your MonacoEditor.tsx to point to the copied worker files:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const validateWorkerPath = async (url: string) => {
  try {
    const response = await fetch(url);
    if (!response.ok) {
      console.error(`Worker file not found at ${url}`);
    } else {
      const contentType = response.headers.get('Content-Type');
      if (contentType && contentType.includes('application/javascript')) {
        console.log(`Worker file found at ${url} and is a valid JavaScript file.`);
      } else {
        console.error(`Worker file at ${url} is not a JavaScript file but a ${contentType}`);
      }
    }
  } catch (error) {
    console.error(`Error fetching worker file at ${url}:`, error);
  }
};

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = "90vh" }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({
      focus: () => {
        monacoEditorRef.current?.focus();
      },
      getValue: () => {
        return monacoEditorRef.current?.getValue() || ''; // Provide a default value
      },
    }));

    useEffect(() => {
      (window as any).MonacoEnvironment = {
        getWorkerUrl: function (_moduleId: string, label: string) {
          let workerUrl = '/editor.worker.js';  // Updated path
          if (label === 'json') {
            workerUrl = '/json.worker.js';  // Updated path
          } else if (label === 'css') {
            workerUrl = '/css.worker.js';  // Updated path
          } else if (label === 'html') {
            workerUrl = '/html.worker.js';  // Updated path
          } else if (label === 'typescript' || label === 'javascript') {
            workerUrl = '/ts.worker.js';  // Updated path
          }
          validateWorkerPath(workerUrl);
          return workerUrl;
        },
      };

      const loadMonacoEditor = async () => {
        const { initVimMode } = await import('monaco-vim');

        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,
          });

                if ((window as any).Vim) {
                  resolve();
                } else {
                  setTimeout(checkVim, 100);
                }

      };
    }, [initialValue, language, onChange, onSave]);

    return <div ref={editorRef} className="monaco-editor-container" style={{ height }} />;
  }
);

export default MonacoEditor;

Step 4: Rebuild and Test

Rebuild your project to ensure the worker files are copied to the dist directory:

yarn build
ls dist

Step 5: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser:

http://localhost:4173/editor.worker.js
http://localhost:4173/json.worker.js
http://localhost:4173/css.worker.js
http://localhost:4173/html.worker.js
http://localhost:4173/ts.worker.js

Summary

By manually copying the worker files using vite-plugin-static-copy and adjusting the worker URLs in the Monaco Editor configuration, you should resolve the issue of the missing editor.worker.bundle.js file. This approach ensures that all necessary worker files are included in the dist directory after the build process.

The error indicates that vite-plugin-static-copy is not found. This could be due to a typo or perhaps the plugin was not installed correctly. Let's correct that by ensuring the correct plugin is installed.

Step 1: Install the Correct Plugin

Since vite-plugin-static-copy was not found, let's ensure it is installed correctly:

yarn add vite-plugin-static-copy -D

Step 2: Verify and Update vite.config.ts

Ensure the plugin is imported correctly in your vite.config.ts:

// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import { viteStaticCopy } from 'vite-plugin-static-copy';

export default defineConfig({
  plugins: [
    react(),
    viteStaticCopy({
      targets: [
        {
          src: 'node_modules/monaco-editor/esm/vs/editor/editor.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/json/json.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/css/css.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/html/html.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/typescript/ts.worker.js',
          dest: '.'
        }
      ]
    })
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
  },
  resolve: {
    alias: {
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

Step 3: Rebuild and Test

Rebuild your project to ensure that the worker files are copied to the dist directory:

yarn build
ls dist

Step 4: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser:

http://localhost:4173/editor.worker.js
http://localhost:4173/json.worker.js
http://localhost:4173/css.worker.js
http://localhost:4173/html.worker.js
http://localhost:4173/ts.worker.js

Summary

By installing the vite-plugin-static-copy correctly and ensuring that the plugin configuration in vite.config.ts is accurate, you should be able to resolve the issue of the missing editor.worker.bundle.js file. This approach ensures that all necessary worker files are included in the dist directory after the build process.

It looks like the files were copied correctly, but your Monaco Editor code is still looking for the .bundle.js files. Since you have renamed the worker files without the .bundle suffix, you need to update the worker URLs accordingly.

Step 1: Update Worker URL Configuration in MonacoEditor.tsx

Ensure that the worker URLs in your Monaco Editor configuration match the filenames in the dist directory:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {

  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const validateWorkerPath = async (url: string) => {
  try {
    const response = await fetch(url);
    if (!response.ok) {
      console.error(`Worker file not found at ${url}`);
    } else {
      const contentType = response.headers.get('Content-Type');
      if (contentType && contentType.includes('application/javascript')) {
        console.log(`Worker file found at ${url} and is a valid JavaScript file.`);
      } else {
        console.error(`Worker file at ${url} is not a JavaScript file but a ${contentType}`);
      }
    }
  } catch (error) {
    console.error(`Error fetching worker file at ${url}:`, error);
  }
};

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = '90vh' }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

      getValue: () => {
        return monacoEditorRef.current?.getValue() || ''; // Provide a default value
      },
    }));

    useEffect(() => {

          } else if (label === 'html') {
            workerUrl = '/html.worker.js'; // Updated path
          } else if (label === 'typescript' || label === 'javascript') {
            workerUrl = '/ts.worker.js'; // Updated path
          }
          validateWorkerPath(workerUrl);
          return workerUrl;
        },
      };

      const loadMonacoEditor = async () => {
        const { initVimMode } = await import('monaco-vim');

        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {

              onChange(editor.getValue());
            }
          });

          const defineVimCommands = async () => {
            await new Promise<void>((resolve) => {
              const checkVim = () => {
                if ((window as any).Vim) {
                  resolve();
                } else {
                  setTimeout(checkVim, 100);
                }
              };
              checkVim();
            });

            const Vim = (window as any).Vim;
            if (Vim) {
              Vim.defineEx('w', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
              });

              Vim.defineEx('q', '', () => {
                if (editorRef.current) {

                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });
            } else {
              console.error('Vim object is not available on the window');
            }
          };

          defineVimCommands();

export default MonacoEditor;

Step 2: Rebuild and Test

Rebuild your project to ensure the worker files are correctly referenced:

yarn build

Step 3: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser again:

The error message about the import statement suggests that the worker files are not being served as modules. This typically occurs when the server doesn't recognize the .js files as ES modules.

Let's address this by ensuring the worker files are loaded as modules.

Step 1: Update Worker Configuration

Update your vite.config.ts to ensure the worker files are served correctly as ES modules:

// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import { viteStaticCopy } from 'vite-plugin-static-copy';

export default defineConfig({
  plugins: [
    react(),
    viteStaticCopy({
      targets: [
        {
          src: 'node_modules/monaco-editor/esm/vs/editor/editor.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/json/json.worker.js',
          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/css/css.worker.js',
          dest: '.'
        },
        {

          dest: '.'
        },
        {
          src: 'node_modules/monaco-editor/esm/vs/language/typescript/ts.worker.js',
          dest: '.'
        }
      ]
    })
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {

    },
  },
  worker: {
    format: 'es',
  },
});

Step 2: Update Worker URL Configuration in MonacoEditor.tsx

Ensure that the worker URLs in your Monaco Editor configuration include the module type:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

      if (contentType && contentType.includes('application/javascript')) {
        console.log(`Worker file found at ${url} and is a valid JavaScript file.`);
      } else {
        console.error(`Worker file at ${url} is not a JavaScript file but a ${contentType}`);
      }
    }
  } catch (error) {

      },
    }));

    useEffect(() => {
      (window as any).MonacoEnvironment = {
        getWorkerUrl: function (_moduleId: string, label: string) {

          }
          validateWorkerPath(workerUrl);
          return `data:application/javascript;charset=utf-8,importScripts("${workerUrl}")`;
        },
      };

      const loadMonacoEditor = async () => {
        const { initVimMode } = await import('monaco-vim');

        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,

          monacoEditorRef.current = editor;

          const statusBarContainer = document.createElement('div');
          statusBarContainer.className = 'status-node';
          document.body.appendChild(statusBarContainer);

          if (!vimModeRef.current) {
            vimModeRef.current = initVimMode(editor, statusBarContainer);
          }

          editor.onDidChangeModelContent(() => {

              checkVim();
            });

            const Vim = (window as any).Vim;
            if (Vim) {
              Vim.defineEx('w', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
              });

              Vim.defineEx('q', '', () => {
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });

              Vim.defineEx('wq', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });
            } else {
              console.error('Vim object is not available on the window');
            }
          };

          defineVimCommands();

          return () => {
            if (vimModeRef.current) vimModeRef.current.dispose();
            editor.dispose();
            if (statusBarContainer && statusBarContainer.parentNode) {
              statusBarContainer.parentNode.removeChild(statusBarContainer);
            }
          };
        }
      };

      loadMonacoEditor();

      return () => {
        if (vimModeRef.current) vimModeRef.current.dispose();
        if (monacoEditorRef.current) monacoEditorRef.current.dispose();
      };
    }, [initialValue, language, onChange, onSave]);

    return <div ref={editorRef} className="monaco-editor-container" style={{ height }} />;
  }
);

export default MonacoEditor;

Step 3: Rebuild and Test

Rebuild your project to ensure the worker files are correctly referenced:

yarn build

Step 4: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser again:

http://localhost:4173/editor.worker.js
http://localhost:4173/json.worker.js
http://localhost:4173/css.worker.js
http://localhost:4173/html.worker.js
http://localhost:4173/ts.worker.js

Summary

By updating the worker URLs in your Monaco Editor configuration to ensure they are served as ES modules, you should resolve the issue of the import statement error. This approach ensures that all necessary worker files are correctly included and referenced in the build process.

The error indicates that the worker files are not being interpreted as ES modules. One common approach to ensure that the workers are loaded correctly as ES modules is to use worker-loader or similar solutions that explicitly configure the workers.

Step 1: Install vite-plugin-monaco-editor

Let's use a Vite plugin that simplifies the integration of the Monaco editor, ensuring the workers are properly configured.

Install the vite-plugin-monaco-editor:

yarn add vite-plugin-monaco-editor -D

Step 2: Update vite.config.ts

Update your vite.config.ts to use the vite-plugin-monaco-editor:

// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import MonacoEditorPlugin from 'vite-plugin-monaco-editor';

export default defineConfig({
  plugins: [
    react(),
    MonacoEditorPlugin({
      // You can specify which languages you want to include
      languageWorkers: ['editorWorkerService', 'typescript', 'json', 'html', 'css']
    })
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
  },
  resolve: {
    alias: {
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
});

Step 3: Clean Up Worker URL Configuration

With the plugin handling the worker configuration, you can clean up the worker URL configuration in your MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = '90vh' }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({
      focus: () => {
        monacoEditorRef.current?.focus();
      },
      getValue: () => {
        return monacoEditorRef.current?.getValue() || ''; // Provide a default value
      },
    }));

    useEffect(() => {
      const loadMonacoEditor = async () => {
        const { initVimMode } = await import('monaco-vim');

        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,
          });

          monacoEditorRef.current = editor;

          const statusBarContainer = document.createElement('div');
          statusBarContainer.className = 'status-node';
          document.body.appendChild(statusBarContainer);

          if (!vimModeRef.current) {
            vimModeRef.current = initVimMode(editor, statusBarContainer);
          }

          editor.onDidChangeModelContent(() => {
            if (onChange) {
              onChange(editor.getValue());
            }
          });

          const defineVimCommands = async () => {
            await new Promise<void>((resolve) => {
              const checkVim = () => {
                if ((window as any).Vim) {
                  resolve();
                } else {
                  setTimeout(checkVim, 100);
                }
              };
              checkVim();
            });

            const Vim = (window as any).Vim;
            if (Vim) {
              Vim.defineEx('w', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
              });

              Vim.defineEx('q', '', () => {
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });

              Vim.defineEx('wq', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });
            } else {
              console.error('Vim object is not available on the window');
            }
          };

          defineVimCommands();

          return () => {
            if (vimModeRef.current) vimModeRef.current.dispose();
            editor.dispose();
            if (statusBarContainer && statusBarContainer.parentNode) {
              statusBarContainer.parentNode.removeChild(statusBarContainer);
            }
          };
        }
      };

      loadMonacoEditor();

      return () => {
        if (vimModeRef.current) vimModeRef.current.dispose();
        if (monacoEditorRef.current) monacoEditorRef.current.dispose();
      };
    }, [initialValue, language, onChange, onSave]);

    return <div ref={editorRef} className="monaco-editor-container" style={{ height }} />;
  }
);

export default MonacoEditor;

Step 4: Rebuild and Test

Rebuild your project to ensure the worker files are correctly referenced:

yarn build

Step 5: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser again:

http://localhost:4173/editor.worker.js
http://localhost:4173/json.worker.js

I apologize for the redundancy and confusion. Let's try a different approach to ensure the workers are properly configured as ES modules without relying on additional plugins.

Step 1: Manually Configure Vite to Handle Workers

Update your vite.config.ts to include manual configuration for handling workers:

// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';

export default defineConfig({
  plugins: [
    react()
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'],
        },
      },
    },
  },
  resolve: {
    alias: {
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

Step 2: Update Worker URL Configuration in MonacoEditor.tsx

Update your MonacoEditor.tsx to ensure it correctly points to the worker URLs and handles them as ES modules:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = '90vh' }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({
      focus: () => {
        monacoEditorRef.current?.focus();
      },
      getValue: () => {
        return monacoEditorRef.current?.getValue() || ''; // Provide a default value
      },
    }));

    useEffect(() => {
      (window as any).MonacoEnvironment = {
        getWorker: function (_moduleId: string, label: string) {
          if (label === 'json') {
            return new Worker(new URL('monaco-editor/esm/vs/language/json/json.worker.js', import.meta.url), { type: 'module' });
          } else if (label === 'css') {
            return new Worker(new URL('monaco-editor/esm/vs/language/css/css.worker.js', import.meta.url), { type: 'module' });
          } else if (label === 'html') {
            return new Worker(new URL('monaco-editor/esm/vs/language/html/html.worker.js', import.meta.url), { type: 'module' });
          } else if (label === 'typescript' || label === 'javascript') {
            return new Worker(new URL('monaco-editor/esm/vs/language/typescript/ts.worker.js', import.meta.url), { type: 'module' });
          } else {
            return new Worker(new URL('monaco-editor/esm/vs/editor/editor.worker.js', import.meta.url), { type: 'module' });
          }
        }
      };

      const loadMonacoEditor = async () => {
        const { initVimMode } = await import('monaco-vim');

        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,
          });

          monacoEditorRef.current = editor;

          const statusBarContainer = document.createElement('div');
          statusBarContainer.className = 'status-node';
          document.body.appendChild(statusBarContainer);

          if (!vimModeRef.current) {
            vimModeRef.current = initVimMode(editor, statusBarContainer);
          }

          editor.onDidChangeModelContent(() => {
            if (onChange) {
              onChange(editor.getValue());
            }
          });

          const defineVimCommands = async () => {
            await new Promise<void>((resolve) => {
              const checkVim = () => {
                if ((window as any).Vim) {
                  resolve();
                } else {
                  setTimeout(checkVim, 100);
                }
              };
              checkVim();
            });

            const Vim = (window as any).Vim;
            if (Vim) {
              Vim.defineEx('w', '', () => {
                if (onSave) {
                  onSave(editor.getValue());
                }
              });

              Vim.defineEx('q', '', () => {
                if (editorRef.current) {
                  editorRef.current.style.display = 'none'; // Hide the editor
                }
              });

                }
              });
            } else {
              console.error('Vim object is not available on the window');
            }
          };

          defineVimCommands();

          return () => {
            if (vimModeRef.current) vimModeRef.current.dispose();
            editor.dispose();
            if (statusBarContainer && statusBarContainer.parentNode) {
              statusBarContainer.parentNode.removeChild(statusBarContainer);
            }
          };
        }
      };

      loadMonacoEditor();

      return () => {
        if (vimModeRef.current) vimModeRef.current.dispose();
        if (monacoEditorRef.current) monacoEditorRef.current.dispose();
      };
    }, [initialValue, language, onChange, onSave]);

    return <div ref={editorRef} className="monaco-editor-container" style={{ height }} />;
  }
);

export default MonacoEditor;

Step 3: Rebuild and Test

Rebuild your project to ensure the worker files are correctly referenced:

yarn build

Step 4: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser again:

http://localhost:4173/editor.worker.js
http://localhost:4173/json.worker.js

The repeated loading of the worker file and the cursor resetting indicate that the editor is not properly caching the worker or there is an issue with the worker initialization. This is unusual behavior and suggests that the workers might not be persisting correctly.

Step-by-Step Debugging and Fix

  1. Inspect Network Requests: Ensure that the requests are indeed for the worker files and not something else that might be causing the issue.
  2. Check Cache-Control Headers: Ensure that the worker files have appropriate cache headers to prevent repeated loading.
  3. Ensure Proper Worker Initialization: Make sure the workers are initialized in a way that they persist across operations.

Step 1: Inspect Network Requests

First, let’s confirm that the requests are indeed for the workers. If they are, we need to ensure proper caching.

Step 2: Ensure Proper Cache-Control Headers

If the worker files are being reloaded, it might be due to cache-control headers. Vite should handle this by default, but let’s verify:

Update your Vite config to ensure proper caching:

// vite.config.ts
import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';

export default defineConfig({
  plugins: [
    react()
  ],
  base: '/',
  publicDir: 'public', // Serve static files from the public directory
  build: {
    outDir: 'dist', // Output directory for build files
    target: 'esnext',
    rollupOptions: {
      output: {
        manualChunks: {
          jsonWorker: ['monaco-editor/esm/vs/language/json/json.worker'],
          cssWorker: ['monaco-editor/esm/vs/language/css/css.worker'],
          htmlWorker: ['monaco-editor/esm/vs/language/html/html.worker'],
          tsWorker: ['monaco-editor/esm/vs/language/typescript/ts.worker'],
          editorWorker: ['monaco-editor/esm/vs/editor/editor.worker'],
        },
      },
    },
  },
  resolve: {
    alias: {
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
  server: {
    headers: {
      'Cache-Control': 'public, max-age=31536000',
    },
  },
});

Step 3: Ensure Proper Worker Initialization

Let’s make sure the workers are initialized correctly in MonacoEditor.tsx.

Update your MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = '90vh' }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({
      focus: () => {
        monacoEditorRef.current?.focus();

    return <div ref={editorRef} className="monaco-editor-container" style={{ height }} />;
  }
);

export default MonacoEditor;

Step 4: Rebuild and Test

Rebuild your project to ensure the worker files are correctly referenced:

yarn build

Step 5: Verify Worker URLs in Browser

Run the preview server and verify that all worker files are accessible from the browser:

yarn preview

Check the URLs in the browser again:

http://localhost:4173/editor.worker.js
http://localhost:4173/json.worker.js
http://localhost:4173/css.worker.js
http://localhost:4173/html.worker.js
http://localhost:4173/ts.worker.js

Summary

By ensuring that workers are properly initialized and checking cache-control headers, you should prevent repeated loading of worker files. This approach ensures that all necessary worker files are correctly included and referenced in the build process without causing repeated requests or resetting the cursor position.

You're right. The approach using new Worker(new URL(...)) does indeed load the worker files directly from the module directory, and the files wouldn't need to be in the dist/ directory.

Given that the worker files are being correctly loaded from the module directory, the issue might be related to how the editor or the worker is handling state.

Step-by-Step Debugging and Fix

  1. Ensure worker files are correctly loaded as ES modules.
  2. Ensure the editor state is not being reset on every interaction.

Step 1: Ensure Worker Files are Correctly Loaded as ES Modules

Since the worker files are being loaded correctly, no need to change the worker configuration. Ensure the worker URLs are correct and the workers are being initialized correctly:

    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({

          };

          defineVimCommands();

          return () => {
            if (vimModeRef.current) vimModeRef.current.dispose();

Step 2: Ensure State Persistence

Make sure the editor state is not being reset on every interaction. This can happen if the editor instance is being recreated frequently.

Check how the component is being used and ensure it is not unmounted and remounted frequently.

Step 3: Avoid Re-initializing Editor

Ensure the editor is not being re-initialized on every render. This can be done by only initializing the editor if it has not been initialized already.

Update the useEffect to include a check:

useEffect(() => {
  if (!editorRef.current || monacoEditorRef.current) {
    // Avoid re-initializing the editor if it already exists
    return;
  }

  (window as any).MonacoEnvironment = {

        return new Worker(new URL('monaco-editor/esm/vs/language/css/css.worker.js', import.meta.url), { type: 'module' });
      } else if (label === 'html') {
        return new Worker(new URL('monaco-editor/esm/vs/language/html/html.worker.js', import.meta.url), { type: 'module' });
      } else if (label === 'typescript' || label === 'javascript') {
        return new Worker(new URL('monaco-editor/esm/vs/language/typescript/ts.worker.js', import.meta.url), { type: 'module' });
      } else {

If the editor is closing when you type a character, it could be due to the Vim commands being defined incorrectly or the editor's state being improperly managed. Let's ensure that the Vim commands and editor setup are correct.

### Step 1: Simplify and Debug

First, let's simplify the code to focus on the core functionality and isolate the issue.

### Step 2: Correctly Initialize Vim Mode

Ensure that Vim mode is initialized correctly and that the commands are defined only once.

### Step 3: Ensure Editor State Persistence

Make sure the editor state is managed properly and not reset or disposed of incorrectly.

Here is an updated version of your `MonacoEditor.tsx`:

```tsx
// src/components/MonacoEditor.tsx

Summary

  • Initialization: Ensure the editor is initialized only once.
  • Vim Commands: Define Vim commands only once and ensure they persist across interactions.
  • State Management: Ensure the editor state is not reset or disposed of improperly.

Rebuild and test the application with these changes to see if the issue persists. If the editor still closes when typing, there might be an external factor causing this behavior.

The error indicates that the Vim object is not available on the window, which means the monaco-vim module might not be loaded properly or there is a timing issue with its initialization.

Let's ensure that the monaco-vim module is correctly imported and initialized. We can add a retry mechanism to wait for the Vim object to be available before defining the Vim commands.

Step 1: Ensure monaco-vim is Imported Correctly

Make sure the monaco-vim module is imported correctly and the Vim mode is initialized properly.

Step 2: Add Retry Mechanism for Vim Initialization

Add a retry mechanism to wait for the Vim object to be available before defining the Vim commands.

Here's an updated version of your MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import React, { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

interface MonacoEditorHandle {
  focus: () => void;
  getValue: () => string;
}

const MonacoEditor = forwardRef<MonacoEditorHandle, MonacoEditorProps>(
  ({ initialValue, language, onChange, onSave, height = '90vh' }, ref) => {
    const editorRef = useRef<HTMLDivElement>(null);
    const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    const vimModeRef = useRef<any>(null);

    useImperativeHandle(ref, () => ({
      focus: () => {
        monacoEditorRef.current?.focus();
      },
      getValue: () => {
        return monacoEditorRef.current?.getValue() || ''; // Provide a default value
      },
    }));

    useEffect(() => {
      (window as any).MonacoEnvironment = {
        getWorker: function (_moduleId: string, label: string) {
          if (label === 'json') {
            return new Worker(new URL('monaco-editor/esm/vs/language/json/json.worker.js', import.meta.url), { type: 'module' });
          } else if (label === 'css') {
            return new Worker(new URL('monaco-editor/esm/vs/language/css/css.worker.js', import.meta.url), { type: 'module' });
          } else if (label === 'html') {
            return new Worker(new URL('monaco-editor/esm/vs/language/html/html.worker.js', import.meta.url), { type: 'module' });
          } else if (label === 'typescript' || label === 'javascript') {

                defineVimCommands();
              } else {
                console.error('Vim object was not available after maximum retries');

Summary

  • Retry Mechanism: Added a retry mechanism to wait for the Vim object to be available before defining the Vim commands.
  • Vim Initialization: Ensured that the Vim commands are defined only once.

Rebuild and test the application with these changes to see if the issue persists. This should help in ensuring that the Vim object is available before the commands are defined.
