To resolve these issues, we need to address two main problems:

Monaco Editor Web Workers Configuration: The error regarding the web workers indicates that we need to define MonacoEnvironment.getWorkerUrl to specify the URLs for the different worker scripts.
Vim Object Availability: The error regarding the Vim object suggests that the Vim mode is not being initialized correctly or the Vim object is not being attached to the window in time.

Step 1: Configure Monaco Editor Web Workers

Let's define the MonacoEnvironment.getWorkerUrl function to specify the paths to the worker scripts. Add this configuration at the top of your MonacoEditor.tsx file:

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

// Define MonacoEnvironment configuration to load workers
(window as any).MonacoEnvironment = {
  getWorkerUrl: function (_moduleId, label) {
    if (label === 'json') {
      return './json.worker.bundle.js';
    }
    if (label === 'css') {
      return './css.worker.bundle.js';
    }
    if (label === 'html') {
      return './html.worker.bundle.js';
    }
    if (label === 'typescript' || label === 'javascript') {
      return './ts.worker.bundle.js';
    }
    return './editor.worker.bundle.js';
  },
};

Step 2: Ensure Vim Object Availability

We need to make sure that initVimMode is correctly initializing and attaching the Vim object to the window. Adding some checks and retries can help ensure that the Vim object is available.

Here’s the updated MonacoEditor.tsx file with these changes:

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

// Define MonacoEnvironment configuration to load workers
(window as any).MonacoEnvironment = {
  getWorkerUrl: function (_moduleId, label) {
    if (label === 'json') {
      return './json.worker.bundle.js';
    }
    if (label === 'css') {
      return './css.worker.bundle.js';
    }
    if (label === 'html') {
      return './html.worker.bundle.js';
    }
    if (label === 'typescript' || label === 'javascript') {
      return './ts.worker.bundle.js';
    }
    return './editor.worker.bundle.js';
  },
};

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

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

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

  useEffect(() => {
    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');
      const vimMode = initVimMode(editor, statusBarContainer);

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

      // Function to define Vim commands
      const defineVimCommands = () => {
        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());
            }

The error `SyntaxError: Unexpected token '<'` suggests that the worker files are not being correctly located and loaded, possibly pointing to an HTML file instead of the actual JavaScript worker file. This usually happens when the file paths are incorrect or the webpack configuration is not set up to handle these files correctly.

### Step 1: Ensure Worker Files are Correctly Located

Make sure the worker files (`json.worker.bundle.js`, `css.worker.bundle.js`, etc.) are correctly placed in your public directory or wherever you are serving static files from.

### Step 2: Adjust Webpack Configuration

If you're using webpack, you need to configure it to handle the Monaco Editor's web workers. Here’s a basic setup:

1. **Install Necessary Loaders**:
   ```bash
   npm install monaco-editor-webpack-plugin

Update Your Webpack Configuration: Add the monaco-editor-webpack-plugin to your webpack config.

// webpack.config.js
const MonacoWebpackPlugin = require('monaco-editor-webpack-plugin');

module.exports = {
  // Other configurations...
  plugins: [
    new MonacoWebpackPlugin({
      languages: ['javascript', 'typescript', 'css', 'html', 'json'],
    }),
  ],
  // Add loader for .worker.js files
  module: {
    rules: [
      {
        test: /\.worker\.js$/,
        use: { loader: 'worker-loader' },
      },
      // Other rules...
    ],
  },
};

Step 3: Adjust `getWorkerUrl` Configuration

Update your MonacoEditor.tsx file to match the paths where webpack outputs the worker files. If you are using worker-loader, it should handle it automatically.

Example `MonacoEditor.tsx` with Webpack Configuration

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

// Define MonacoEnvironment configuration to load workers
(window as any).MonacoEnvironment = {
  getWorkerUrl: function (_moduleId, label) {
    if (label === 'json') {
      return './json.worker.bundle.js';
    }
    if (label === 'css') {
      return './css.worker.bundle.js';
    }
    if (label === 'html') {
      return './html.worker.bundle.js';
    }
    if (label === 'typescript' || label === 'javascript') {
      return './ts.worker.bundle.js';
    }
    return './editor.worker.bundle.js';
  },
};

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

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

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

  useEffect(() => {
    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');
      const vimMode = initVimMode(editor, statusBarContainer);

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

      // Function to define Vim commands
      const defineVimCommands = () => {
        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
            }
          });

If you're not using Webpack explicitly, it's possible you're using another build tool like Vite, Create React App (CRA), or another bundler. Each bundler has its own way of handling web workers and custom configurations.

### For Create React App (CRA)

If you're using Create React App, you typically don't have direct access to the webpack configuration without ejecting. However, you can use `react-app-rewired` or `craco` to override the webpack configuration.

#### Using `craco` (Create React App Configuration Override)

1. **Install craco and craco-monaco-editor**:
   ```bash
   npm install @craco/craco craco-monaco-editor

Create craco.config.js in the root of your project:

const CracoMonacoWebpackPlugin = require('craco-monaco-editor');

module.exports = {
  plugins: [
    {
      plugin: CracoMonacoWebpackPlugin,
      options: {
        languages: ['javascript', 'typescript', 'css', 'html', 'json']
      }
    }
  ]
};

Update package.json scripts:

"scripts": {
  "start": "craco start",
  "build": "craco build",
  "test": "craco test",
  "eject": "react-scripts eject"
}

For Vite

If you're using Vite, you can configure it to handle Monaco Editor's web workers:

Install the necessary plugin:
```
npm install vite-plugin-monaco-editor
```

Update vite.config.ts:

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import monacoEditorPlugin from 'vite-plugin-monaco-editor';

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin()
  ]
});

Handling Monaco Worker URL in the Code

Regardless of the tool, ensure that the worker URLs in your MonacoEditor.tsx match the paths where the bundler outputs the worker files.

Here's the updated MonacoEditor.tsx code snippet:

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

// Define MonacoEnvironment configuration to load workers
(window as any).MonacoEnvironment = {
  getWorkerUrl: function (_moduleId, label) {
    if (label === 'json') {
      return './json.worker.bundle.js';
    }
    if (label === 'css') {
      return './css.worker.bundle.js';
    }
    if (label === 'html') {
      return './html.worker.bundle.js';
    }
    if (label === 'typescript' || label === 'javascript') {
      return './ts.worker.bundle.js';
    }
    return './editor.worker.bundle.js';
  },
};

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

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

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

  useEffect(() => {
    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');
      const vimMode = initVimMode(editor, statusBarContainer);

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

      // Function to define Vim commands
      const defineVimCommands = () => {
        const Vim = (window as any).Vim;
        if (Vim) {
          Vim.defineEx('w', '', () => {
            if (onSave) {
              onSave(editor.getValue());

Great! Since you're using Vite, you can follow these steps to configure Vite to handle Monaco Editor and its web workers properly.

### Step 1: Install the Necessary Plugin

First, you need to install the `vite-plugin-monaco-editor` plugin:

```bash
yarn add vite-plugin-monaco-editor

Step 2: Update Vite Configuration

Next, update your vite.config.ts file to include the vite-plugin-monaco-editor plugin:

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

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin({
      // You can specify the languages you need here
      languages: ['javascript', 'typescript', 'css', 'html', 'json'],
    }),
  ],
});

Step 3: Update `MonacoEditor.tsx`

Ensure your MonacoEditor.tsx handles the worker URLs correctly. Since Vite and the plugin will handle the worker paths, we don't need to manually define the worker URLs in the MonacoEnvironment.

Here's the updated MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { initVimMode } from 'monaco-vim';
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;
}

The error indicates that the languages property is not recognized in the configuration object for vite-plugin-monaco-editor. It seems like the plugin might have updated its API or the property is not directly supported.

To resolve this, you can adjust your vite.config.ts configuration by removing the languages property and instead rely on the default configuration of the plugin.

Here’s the simplified vite.config.ts:

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

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin(),
  ],
});

This will use the default settings of vite-plugin-monaco-editor, and it should handle the necessary configurations for Monaco Editor's web workers.

Step 4: Verify and Run

After making these changes, run your Vite development server:

yarn dev

This should resolve the configuration error. If you still encounter issues, please ensure that your dependencies are up to date and that there are no conflicts.

The errors you're encountering indicate that the Monaco Editor's web workers are still not being correctly configured and the Vim object is not being found. Since Vite handles web workers differently, let's ensure that the plugin vite-plugin-monaco-editor is correctly configured, and we properly set up the MonacoEnvironment.

Step 1: Ensure Correct Plugin Configuration

First, make sure you have the correct version of vite-plugin-monaco-editor installed. If you're using the latest version, it should handle the configuration of the workers:

yarn add vite-plugin-monaco-editor

Step 2: Update Vite Configuration

Update your vite.config.ts:

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

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin(),
  ],
});

Step 3: Correct `MonacoEditor.tsx` Configuration

Ensure your MonacoEditor.tsx handles the worker URLs correctly and that the Vim mode is set up properly. We don't need to define the worker URLs in MonacoEnvironment if the plugin handles it.

Here's the updated MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { initVimMode } from 'monaco-vim';
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;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

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

  useEffect(() => {
    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');
      const vimMode = initVimMode(editor, statusBarContainer);

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

      // Function to define Vim commands
      const defineVimCommands = () => {
        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');
        }
      };

      // Ensure Vim commands are defined after Vim mode is initialized
      // Retry every 100ms until Vim is available, up to a maximum of 10 retries
      let retries = 0;
      const maxRetries = 10;
      const intervalId = setInterval(() => {
        if ((window as any).Vim || retries >= maxRetries) {
          clearInterval(intervalId);
          if ((window as any).Vim) {
            defineVimCommands();
          } else {
            console.error('Vim object was not available after maximum retries');
          }
        }
        retries++;
      }, 100);

      return () => {
        vimMode.dispose();
        editor.dispose();
      };
    }
  }, [initialValue, language, onChange, onSave]);

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

export default MonacoEditor;

Given that the issue persists, let's take a more detailed approach to ensure everything is properly set up.

Step 1: Verify Plugin Installation

Ensure you have the correct vite-plugin-monaco-editor plugin installed:

yarn add vite-plugin-monaco-editor

Step 2: Configure Vite

Make sure your vite.config.ts file includes the vite-plugin-monaco-editor plugin:

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

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin(),
  ],
});

Step 3: Update `MonacoEditor.tsx`

Ensure your MonacoEditor.tsx is correctly set up. Since vite-plugin-monaco-editor handles worker URLs, we should not need to set MonacoEnvironment.getWorkerUrl. However, let's add some checks to ensure the Vim mode is correctly initialized and the Vim commands are available.

Here's the updated MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { initVimMode } from 'monaco-vim';
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;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

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

  useEffect(() => {
    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');
      const vimMode = initVimMode(editor, statusBarContainer);

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

      const defineVimCommands = () => {
        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');
        }
      };

      let retries = 0;
      const maxRetries = 10;
      const intervalId = setInterval(() => {
        if ((window as any).Vim || retries >= maxRetries) {
          clearInterval(intervalId);
          if ((window as any).Vim) {
            defineVimCommands();
          } else {
            console.error('Vim object was not available after maximum retries');
          }
        }
        retries++;
      }, 100);

      return () => {
        vimMode.dispose();
        editor.dispose();
      };
    }
  }, [initialValue, language, onChange, onSave]);

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

export default MonacoEditor;

Step 4: Debugging

If you still encounter issues, let's debug step-by-step:

Check Console for Additional Errors: Ensure there are no other errors in the console that might give more clues about the issue.
Ensure Worker Files are Loaded Correctly: Verify that the worker files are being served correctly. You can do this by checking the network tab in your browser's developer tools to see if the worker files are being loaded.

The error TypeError: monacoEditorPlugin is not a function indicates that the plugin might not be imported correctly. Let's ensure that we are using the correct version of vite-plugin-monaco-editor and importing it correctly.

Step 1: Verify Plugin Version

Ensure you have the correct version of vite-plugin-monaco-editor installed:

yarn add vite-plugin-monaco-editor

Step 2: Update Vite Configuration

Ensure that the plugin is imported and used correctly in your vite.config.ts. The plugin should be imported as a default export.

Here's the updated configuration:

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

// Ensure monacoEditorPlugin is a function
if (typeof monacoEditorPlugin !== 'function') {
  throw new Error('Expected monacoEditorPlugin to be a function');
}

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin(),
  ],
});

Step 3: Update `MonacoEditor.tsx`

Ensure your MonacoEditor.tsx does not attempt to manually set worker URLs if the plugin handles it. Here’s a simplified example:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { initVimMode } from 'monaco-vim';
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;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

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

  useEffect(() => {
    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');
      const vimMode = initVimMode(editor, statusBarContainer);

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

      const defineVimCommands = () => {
        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');
        }
      };

      let retries = 0;
      const maxRetries = 10;
      const intervalId = setInterval(() => {
        if ((window as any).Vim || retries >= maxRetries) {
          clearInterval(intervalId);
          if ((window as any).Vim) {
            defineVimCommands();
          } else {
            console.error('Vim object was not available after maximum retries');
          }
        }
        retries++;
      }, 100);

      return () => {
        vimMode.dispose();
        editor.dispose();
      };
    }
  }, [initialValue, language, onChange, onSave]);

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

export default MonacoEditor;

Step 4: Verify and Run

Finally, redeploy your project by running:

yarn dev

This setup should resolve the issue with monacoEditorPlugin not being recognized as a function and should properly initialize Monaco Editor and Vim mode. If the problem persists, please double-check the

Switching to the newer vim-monaco library might indeed help simplify the integration and reduce dependencies. Here’s how you can update your implementation to use vim-monaco.

Step 1: Install `vim-monaco`

First, install the vim-monaco package:

yarn add vim-monaco

Step 2: Update `MonacoEditor.tsx`

Here’s how you can update your MonacoEditor.tsx to use vim-monaco:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
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;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

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

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

      monacoEditorRef.current = editor;

      const vimMode = new VimMode(editor);
      vimModeRef.current = vimMode;

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

      const defineVimCommands = () => {
        if (vimMode) {
          vimMode.defineEx('w', '', () => {
            if (onSave) {
              onSave(editor.getValue());
            }
          });

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

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

      defineVimCommands();

      return () => {
        vimMode.dispose();
        editor.dispose();
      };
    }
  }, [initialValue, language, onChange, onSave]);

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

export default MonacoEditor;

Step 3: Verify and Run

After making these changes, run your Vite development server:

yarn dev

This setup should simplify the integration and reduce dependencies. Make sure to test Vim commands like :w, :q, and :wq to verify they work as expected. If any issues arise, check the console for errors and ensure that vim-monaco is properly installed and imported.

It appears that monacoEditorPlugin from vite-plugin-monaco-editor might not be a default export, which is causing the monacoEditorPlugin is not a function error. Let's check the correct way to import and use the plugin.

Step 1: Correct the Import Statement

The vite-plugin-monaco-editor might be using named exports instead of a default export. Let's adjust the import statement accordingly.

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

// Ensure monacoEditorPlugin is a function
if (typeof monacoEditorPlugin !== 'function') {
  throw new Error('Expected monacoEditorPlugin to be a function');
}

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin({
      // You can specify the languages you need here
    }),
  ],
  base: '/',
  build: {
    target: 'esnext'
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
    }
  },
});

Step 2: Reinstall Dependencies

Just to be sure, clear your node_modules and reinstall dependencies:

rm -rf node_modules
yarn install

Step 3: Start the Development Server

Run your development server again:

yarn dev

Step 4: Verify Configuration

Ensure that the vite-plugin-monaco-editor package is correctly installed and there are no version mismatches.

Additional Debugging

If the problem persists, you can add a debug log to see what is being imported:

import { monacoEditorPlugin } from 'vite-plugin-monaco-editor';
console.log(monacoEditorPlugin); // Add this line to check what is being imported

Final Confirmation

Make sure your package.json dependencies are correct and there are no conflicts. This should resolve the issue with monacoEditorPlugin not being recognized as a function. If the problem still persists, consider checking the plugin's repository for any updates or breaking changes.

Given that monacoEditorPlugin is indeed the default export, the issue might be due to how the module is being resolved or an inconsistency with the installed package.

Let's make sure everything is correctly set up. Here are the steps:

Step 1: Ensure Correct Plugin Import

Keep the default import since monacoEditorPlugin is the default export.

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

// Ensure monacoEditorPlugin is a function
if (typeof monacoEditorPlugin !== 'function') {
  throw new Error('Expected monacoEditorPlugin to be a function');
}

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin({
      // You can specify the languages you need here
    }),
  ],
  base: '/',
  build: {
    target: 'esnext'
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
    }
  },
});

Step 2: Clear Node Modules and Reinstall

Let's clear the node_modules directory and reinstall dependencies to ensure there are no conflicting versions.

rm -rf node_modules
yarn install

Step 3: Check for Typing Errors

Make sure there are no TypeScript typing errors. Sometimes, TypeScript might have issues with type definitions, especially if there are conflicting versions.

Step 4: Verify Plugin Version

Double-check the version of vite-plugin-monaco-editor in package.json:

"dependencies": {
  "vite-plugin-monaco-editor": "^1.1.0"
}

Step 5: Run the Development Server

Try running the development server again:

yarn dev

Additional Debugging:

If the issue persists, you can add a debug statement to log what is being imported:

import monacoEditorPlugin from 'vite-plugin-monaco-editor';
console.log(monacoEditorPlugin); // Check what is being imported

if (typeof monacoEditorPlugin !== 'function') {
  throw new Error('Expected monacoEditorPlugin to be a function');
}

Final Steps:

If you still encounter issues, consider the following:

Check Node Version: Ensure your Node.js version is compatible with your dependencies.
Check Vite Version: Ensure that your Vite version is compatible with vite-plugin-monaco-editor.
Isolate the Issue: Create a minimal reproduction repository to isolate the issue. Sometimes, starting with a fresh project can help identify conflicts.

It looks like the monacoEditorPlugin is being imported as an object with a default property, which contains the actual function. This indicates that the module might be using CommonJS style exports, and you need to access the default property to get the function.

Adjusting the Import

Since the plugin is exporting the function as default, you can adjust your import to access the default property.

Here’s how you can update your vite.config.ts:

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

// Ensure monacoEditorPlugin.default is a function
const monacoEditorPluginFunction = monacoEditorPlugin.default || monacoEditorPlugin;

if (typeof monacoEditorPluginFunction !== 'function') {
  throw new Error('Expected monacoEditorPlugin to be a function');
}

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginFunction({
      // You can specify the languages you need here
    }),
  ],
  base: '/',
  build: {
    target: 'esnext'
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
    }
  },
});

Explanation

Check for default Property: The monacoEditorPlugin object includes a default property, which is the actual function. The line const monacoEditorPluginFunction = monacoEditorPlugin.default || monacoEditorPlugin; ensures that you get the correct function.
Type Check: Ensure that the resolved monacoEditorPluginFunction is indeed a function.

Reinstall Dependencies

Although you’ve already reinstalled the dependencies, it’s a good practice to remove node_modules and reinstall one more time to ensure no conflicts:

rm -rf node_modules
yarn install

Run the Development Server

Try running the development server again:

yarn dev

This should resolve the issue of monacoEditorPlugin not being recognized as a function. If the problem persists, please double-check the package.json dependencies and ensure that there are no version mismatches or conflicting plugins.

Given the error, it seems that TypeScript is not recognizing the default property on the monacoEditorPlugin import. This could be due to type definitions not matching the actual module structure. Let's try to resolve this by explicitly handling the import and using TypeScript's type assertion.

Solution: Type Assertion for Imports

We can use a type assertion to tell TypeScript that monacoEditorPlugin can have a default property.

Step 1: Update `vite.config.ts`

Here’s how you can handle the import and type assertion:

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

// Type assertion to handle the default property
const monacoEditorPlugin = (monacoEditorPluginImport as any).default || monacoEditorPluginImport;

if (typeof monacoEditorPlugin !== 'function') {
  throw new Error('Expected monacoEditorPlugin to be a function');
}

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin({
      // You can specify the languages you need here
    }),
  ],
  base: '/',
  build: {
    target: 'esnext'
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
    }
  },
});

Explanation

Type Assertion: The line const monacoEditorPlugin = (monacoEditorPluginImport as any).default || monacoEditorPluginImport; tells TypeScript to treat monacoEditorPluginImport as an any type, allowing us to access the default property if it exists.
Type Check: The type check ensures that monacoEditorPlugin is a function.

Step 2: Reinstall Dependencies (if needed)

If you haven't already, you can remove node_modules and reinstall dependencies:

rm -rf node_modules
yarn install

Step 3: Run the Development Server

Try running the development server again:

yarn dev

Additional Debugging

If the issue persists, you can add more debug statements to verify the structure of the imported module:

import monacoEditorPluginImport from 'vite-plugin-monaco-editor';
console.log(monacoEditorPluginImport); // Check the structure of the import

const monacoEditorPlugin = (monacoEditorPluginImport as any).default || monacoEditorPluginImport;

This should help resolve the issue with monacoEditorPlugin not being recognized as a function while ensuring TypeScript handles the import correctly.

The errors you're seeing are related to the WebSocket connection for Vite's hot module replacement (HMR) and an issue with reading an undefined property in your code.

Step 1: Fix WebSocket URL for Vite HMR

The WebSocket URL ws://localhost:undefined/ suggests that the port is not being correctly set. This can happen if the Vite server configuration is incorrect or if environment variables are not properly set.

Let's ensure that Vite is correctly configured to use the right port.

1.1 Ensure Correct Vite Configuration

Make sure your vite.config.ts includes the correct server configuration:

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

// Type assertion to handle the default property
const monacoEditorPlugin = (monacoEditorPluginImport as any).default || monacoEditorPluginImport;

if (typeof monacoEditorPlugin !== 'function') {
  throw new Error('Expected monacoEditorPlugin to be a function');
}

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin({
      // You can specify the languages you need here
    }),
  ],
  server: {
    port: 5173, // Ensure the port is set correctly
  },
  base: '/',
  build: {
    target: 'esnext'
  },
  resolve: {
    alias: {
      '/shared/': path.resolve(__dirname, '../shared/'),
    }
  },
});

1.2 Check Environment Variables

Ensure that there are no environment variables overriding the port or causing issues. Check your .env file or Vite environment configuration.

Step 2: Fix `SelectionDirection` Undefined Property

The error Cannot read properties of undefined (reading 'SelectionDirection') in adapter.ts seems to indicate that a value is not being initialized properly. This could be a bug in your code or an issue with the Monaco Editor configuration.

2.1 Debug the Code

Locate the code in adapter.ts and add checks or debugging statements:

// adapter.ts
const selectionDirection = editor.getSelection()?.SelectionDirection;
if (!selectionDirection) {
  console.error('SelectionDirection is undefined');
}

2.2 Ensure Proper Initialization

Make sure that your Monaco Editor is properly initialized and that SelectionDirection is available. This might involve checking the editor's state or ensuring that the editor instance is correctly set up before using its properties.

Step 3: Run the Development Server

After making these changes, restart your development server:

yarn dev

Additional Steps

Check Network Requests: Open your browser's developer tools and check the Network tab to ensure that all resources are being loaded correctly.
Console Logs: Check the console logs for any additional errors or warnings that might give more clues about what is going wrong.

By following these steps, you should be able to resolve the WebSocket URL issue for Vite HMR and address the SelectionDirection undefined property error. If the issue persists, please provide more details about the code in adapter.ts and any relevant parts of your setup.

The TypeError: Cannot read properties of undefined (reading 'SelectionDirection') error indicates that the property SelectionDirection is being accessed on an undefined object. This typically means that the object you're trying to access hasn't been properly initialized or is not available at the time of access.

Step 1: Add Null Checks

We need to ensure that the object and its properties are defined before accessing them. Here's how you can add null checks in your adapter.ts file:

// adapter.ts
const selection = editor.getSelection();
if (selection && selection.SelectionDirection) {
  const selectionDirection = selection.SelectionDirection;
  // Proceed with your logic...
} else {
  console.error('Selection or SelectionDirection is undefined');
}

Step 2: Ensure Proper Initialization

Ensure that the editor instance is properly initialized and that the getSelection method returns a valid object.

Step 3: Verify Monaco Editor Setup

Make sure your Monaco Editor setup is correct. Here's a simplified example of initializing the Monaco Editor and ensuring it's ready before accessing its properties:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
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;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

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

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

      monacoEditorRef.current = editor;

      const vimMode = new VimMode(editor);
      vimModeRef.current = vimMode;

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

      const defineVimCommands = () => {
        if (vimMode) {
          vimMode.defineEx('w', '', () => {
            if (onSave) {
              onSave(editor.getValue());
            }
          });

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

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

      defineVimCommands();

      return () => {
        vimMode.dispose();
        editor.dispose();
      };
    }
  }, [initialValue, language, onChange, onSave]);

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

export default MonacoEditor;

Step 4: Verify and Debug

Make sure to check the browser console for any additional logs or errors that might provide more information about the state of your application.

Final Steps

After making these changes, restart your development server:

yarn dev

This should help ensure that the SelectionDirection property is accessed only when it's available, preventing the TypeError. If the issue persists, please provide more details about the adapter.ts code and how the editor instance is being initialized.

No, you generally shouldn't edit files in the node_modules directory because these are third-party libraries and your changes will be overwritten if the package is updated.

Given that the error is originating from a third-party library, it suggests there might be an issue with how the library is being used or with the library itself. Here are a few steps you can take to address the issue without directly modifying node_modules:

Step 1: Ensure Proper Initialization

Ensure that your usage of vim-monaco is correct and that the editor is fully initialized before invoking any Vim-specific functionality.

Step 2: Add Error Handling in Your Code

You can add error handling in your code where you use the vim-monaco library to ensure that any undefined properties are handled gracefully.

Step 3: Report an Issue

If you suspect this is a bug in the library, consider reporting an issue to the maintainers of vim-monaco. Provide a detailed description of the problem along with any relevant code snippets.

Step 4: Use a Workaround

If the issue is critical and you need an immediate workaround, you could create a wrapper around the vim-monaco initialization to handle potential undefined properties. Here’s an example:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';

The linter error indicates that TypeScript is having trouble finding the type declarations for the vim-monaco module, even though they exist in the package. This issue typically arises due to misconfigured package.json exports or incorrect TypeScript setup.

Step 1: Create a Type Declaration File

To resolve the issue, you can create a custom type declaration file for vim-monaco in your project. This will ensure TypeScript knows how to handle the module.

Create a new file vim-monaco.d.ts in your src/types directory:

// src/types/vim-monaco.d.ts
declare module 'vim-monaco' {
  import * as monaco from 'monaco-editor';

  export class VimMode {
    constructor(editor: monaco.editor.IStandaloneCodeEditor);
    dispose(): void;
    defineEx(cmd: string, defaultKey: string, callback: () => void): void;
  }
}

Update tsconfig.json to include the custom type declarations:

// tsconfig.json
{
  "compilerOptions": {
    "typeRoots": ["./node_modules/@types", "./src/types"],
    // other options...
  }
}

Step 2: Restart Your Development Server

After adding the custom type declaration, restart your development server to ensure the changes take effect:

yarn dev

Step 3: Verify the Linter

Check if the linter error is resolved and if the TypeScript compiler recognizes the vim-monaco types.

Step 4: Test Your Application

Make sure to thoroughly test your application to ensure that the vim-monaco integration works as expected and that no runtime errors occur.

Example of Updated `MonacoEditor.tsx`

Here's how your MonacoEditor.tsx might look with the custom type declarations:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
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;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

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

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

      monacoEditorRef.current = editor;

      try {
        // Initialize Vim mode with error handling
        const vimMode = new VimMode(editor);
        vimModeRef.current = vimMode;

        // Define Vim commands
        const defineVimCommands = () => {
          if (vimMode) {
            vimMode.defineEx('w', '', () => {
              if (onSave) {
                onSave(editor.getValue());
              }
            });

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

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

        defineVimCommands();

      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

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

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

The `TypeError: Cannot read properties of undefined (reading 'SelectionDirection')` error suggests that the `SelectionDirection` property is being accessed on an undefined object. Given that this is happening in `adapter.ts` in the `vim-monaco` library, it's likely that the library is trying to access this property before the editor is fully initialized or under certain conditions where the `SelectionDirection` does not exist.

Since the error is within a third-party library, you can't directly fix the library code. However, you can ensure that the Monaco Editor is properly initialized and handle potential timing issues in your integration.

### Step 1: Ensure Proper Initialization and Error Handling

Make sure that the Monaco Editor and Vim mode are fully initialized before any operations that might access `SelectionDirection`.

Here's an updated approach to ensure proper initialization and error handling in your `MonacoEditor.tsx`:

```tsx
// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
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;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

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

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

      monacoEditorRef.current = editor;

      // Initialize Vim mode with error handling
      try {
        const vimMode = new VimMode(editor);
        vimModeRef.current = vimMode;

        // Define Vim commands
        const defineVimCommands = () => {
          if (vimMode) {
            vimMode.defineEx('w', '', () => {
              if (onSave) {
                onSave(editor.getValue());
              }
            });

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

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

        defineVimCommands();

      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

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

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

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

export default MonacoEditor;

Step 2: Add Debugging Information

Add additional logging to understand the state of the editor and Vim mode when the error occurs:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
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;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null
