The error Unexpected token '<' usually indicates that the web worker is trying to load an HTML file instead of the expected JavaScript file. This can happen if the worker paths are not correctly configured.

Given your setup with vite, you need to ensure that the web workers are correctly referenced in your configuration.

Here's a detailed approach to fix this issue:

1. Ensure Monaco Environment Configuration

Make sure you define MonacoEnvironment properly to handle worker paths. This can be done in the same file where you're using the Monaco editor, typically in MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import React, { 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;
}

// ... rest of the component code

2. Vite Configuration

Ensure that your vite.config.ts is properly set up to handle the workers. You've already defined the worker chunks, but make sure the paths align with the MonacoEnvironment configuration:

// vite.config.ts
import { defineConfig } 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'], 
    }),
  ],
  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'),
    },
  },
  worker: {
    format: 'es',
  }
})

3. Verify Worker Files

Make sure the worker files (json.worker.bundle.js, css.worker.bundle.js, html.worker.bundle.js, ts.worker.bundle.js, editor.worker.bundle.js) are being correctly generated and placed in the appropriate directory during the build process.

4. Check Network Requests

Open the browser's developer tools and check the network tab to ensure that the worker files are being correctly requested and served. This can help identify if there are any path issues.

5. Clear Cache and Restart

Sometimes, old cache can cause issues. Clear your browser's cache and restart your development server.

By ensuring that your MonacoEnvironment configuration aligns with your Vite setup, you should be able to resolve the Unexpected token '<' error.

To verify the paths and ensure everything is working correctly, we can add some console.log() statements and use the browser's developer tools to inspect the network requests. Here is a more concrete step-by-step guide:

Step 1: Add Debug Logs in `MonacoEnvironment`

Add console.log() statements to the getWorkerUrl function in MonacoEnvironment. This will help you see which worker URLs are being requested.

// src/components/MonacoEditor.tsx
import React, { 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) {
    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';
    }
    console.log(`Loading worker for ${label}: ${workerUrl}`);
    return workerUrl;
  },
};

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

// ... rest of the component code

Step 2: Run Your Application

Start your development server and open your application in the browser.

npm run dev

Step 3: Inspect Network Requests

Open the developer tools in your browser (usually F12 or right-click -> Inspect).
Go to the "Network" tab.
Filter by "JS" to see only JavaScript files.
Interact with your Monaco editor to trigger the loading of workers.
Look for requests to json.worker.bundle.js, css.worker.bundle.js, html.worker.bundle.js, ts.worker.bundle.js, and editor.worker.bundle.js.

Step 4: Check Console Logs

Check the console logs to ensure that the worker URLs are being logged correctly. This will help you verify that the getWorkerUrl function is being called and the correct URLs are being generated.

Step 5: Validate Worker Files

Ensure that the worker files are being served correctly. You can do this by manually navigating to the URLs of the worker files in your browser. For example:

http://localhost:5173/json.worker.bundle.js
http://localhost:5173/css.worker.bundle.js
http://localhost:5173/html.worker.bundle.js
http://localhost:5173/ts.worker.bundle.js
http://localhost:5173/editor.worker.bundle.js

If these files do not exist or return a 404 error, then there may be an issue with your build configuration.

Step 6: Clear Cache and Restart

Clear your browser's cache to ensure that old files are not causing issues. Restart your development server to apply all changes.

Additional Debugging

If any of the above steps indicate an issue, you can add more specific console.log() statements or use a Node path validator to check the existence of the files during the build process.

For example, you can add a script in your vite.config.ts to check if the files exist after the build:

import fs from 'fs';
import path from 'path';

const workerFiles = [
  'json.worker.bundle.js',
  'css.worker.bundle.js',
  'html.worker.bundle.js',
  'ts.worker.bundle.js',
  'editor.worker.bundle.js',
];

workerFiles.forEach(file => {
  const filePath = path.resolve(__dirname, 'dist', file);
  if (fs.existsSync(filePath)) {
    console.log(`Worker file exists: ${filePath}`);
  } else {
    console.error(`Worker file missing: ${filePath}`);
  }
});

Add this script after the build process in your vite.config.ts:

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import path from 'path'
import fs from 'fs';

import monacoEditorPlugin, { type IMonacoEditorOpts } from 'vite-plugin-monaco-editor';

const monacoEditorPluginDefault = ((monacoEditorPlugin as any).default) as (options: IMonacoEditorOpts) => any;

const workerFiles = [
  'json.worker.bundle.js',
  'css.worker.bundle.js',
  'html.worker.bundle.js',
  'ts.worker.bundle.js',
  'editor.worker.bundle.js',
];

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({ 
      languageWorkers: ['typescript', 'json', 'html', 'css'], 
    }),
  ],
  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'),
    },
  },
  worker: {
    format: 'es',
  },
  buildEnd() {
    workerFiles.forEach(file => {
      const filePath = path.resolve(__dirname, 'dist', file);
      if (fs.existsSync(filePath)) {
        console.log(`Worker file exists: ${filePath}`);
      } else {
        console.error(`Worker file missing: ${filePath}`);
      }
    });
  }
});

This will log the existence of the worker files after the build process, helping you verify that they are being correctly generated and placed.

This indicates that the path to your worker files is incorrect, causing them to be served as the main HTML page instead of the expected JavaScript files. Let's address this by ensuring the worker files are correctly generated and accessible.

Step 1: Ensure Worker Files are Generated

First, ensure that the worker files are generated correctly during the build process. This can be confirmed by checking the dist directory after building your project.

Build your project:
```
npm run build
```
Check the dist directory: Navigate to the dist directory and ensure that the worker files (json.worker.bundle.js, css.worker.bundle.js, html.worker.bundle.js, ts.worker.bundle.js, editor.worker.bundle.js) are present.

Step 2: Update Worker URLs in `vite.config.ts`

Modify your vite.config.ts to ensure that the worker files are correctly referenced. Use absolute paths to reference the worker files:

import { defineConfig } 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'], 
    }),
  ],
  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'),
    },
  },
  worker: {
    format: 'es',
  },
  buildEnd() {
    const workerFiles = [
      'json.worker.bundle.js',
      'css.worker.bundle.js',
      'html.worker.bundle.js',
      'ts.worker.bundle.js',
      'editor.worker.bundle.js',
    ];
    workerFiles.forEach(file => {
      const filePath = path.resolve(__dirname, 'dist', file);
      if (fs.existsSync(filePath)) {
        console.log(`Worker file exists: ${filePath}`);
      } else {
        console.error(`Worker file missing: ${filePath}`);
      }
    });
  }
});

Step 3: Update `MonacoEnvironment` Configuration

Update your MonacoEnvironment configuration in MonacoEditor.tsx to use absolute paths:

// src/components/MonacoEditor.tsx
import React, { 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) {
    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';
    }
    console.log(`Loading worker for ${label}: ${workerUrl}`);
    return workerUrl;
  },
};

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

// ... rest of the component code

Step 4: Clear Cache and Restart

Clear your browser's cache and restart your development server to ensure that any old files are not causing issues.

npm run dev

Step 5: Verify Network Requests Again

Open the developer tools in your browser.
Go to the "Network" tab.
Filter by "JS" to see only JavaScript files.
Interact with your Monaco editor to trigger the loading of workers.
Look for requests to json.worker.bundle.js, css.worker.bundle.js, html.worker.bundle.js, ts.worker.bundle.js, and editor.worker.bundle.js.

By following these steps, you should be able to resolve the issue with the worker files and ensure they are correctly loaded.

The error you're encountering indicates that the buildEnd property is not recognized in the Vite configuration. Vite's configuration does not directly support a buildEnd property in the defineConfig object. Instead, you can use Vite's plugin system to hook into build lifecycle events.

Here is how you can create a custom Vite plugin to log the existence of the worker files after the build process:

Step 1: Create a Custom Plugin

Define a custom plugin in your vite.config.ts:

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

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;

// Custom plugin to verify worker files after the build
const verifyWorkerFilesPlugin: Plugin = {
  name: 'verify-worker-files',
  closeBundle() {
    const workerFiles = [
      'json.worker.bundle.js',
      'css.worker.bundle.js',
      'html.worker.bundle.js',
      'ts.worker.bundle.js',
      'editor.worker.bundle.js',
    ];
    workerFiles.forEach(file => {
      const filePath = path.resolve(__dirname, 'dist', file);
      if (fs.existsSync(filePath)) {
        console.log(`Worker file exists: ${filePath}`);
      } else {
        console.error(`Worker file missing: ${filePath}`);
      }
    });
  },
};

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
    }),
    verifyWorkerFilesPlugin, // Add the custom plugin here
  ],
  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'),
    },
  },
  worker: {
    format: 'es',
  },
});

Step 2: Clear Cache and Restart

Clear your browser's cache and restart your development server to ensure that any old files are not causing issues.

npm run dev

Step 3: Verify Network Requests Again

Open the developer tools in your browser.
Go to the "Network" tab.
Filter by "JS" to see only JavaScript files.
Interact with your Monaco editor to trigger the loading of workers.
Look for requests to json.worker.bundle.js, css.worker.bundle.js, html.worker.bundle.js, ts.worker.bundle.js, and editor.worker.bundle.js.

By following these steps, you should be able to resolve the issue with the worker files and ensure they are correctly loaded.

The editor.worker.bundle.js and other worker bundle files are supposed to be produced by the build process of Vite, especially since you are using vite-plugin-monaco-editor. The purpose of this plugin is to handle the bundling of Monaco editor workers correctly.

Let's address your questions step-by-step:

Where Should the Files Be in the File System?

After building your project, the worker files should be located in the dist directory (or whatever your output directory is if configured differently).

What Process Creates the Files?

The Vite build process, with the help of vite-plugin-monaco-editor, is responsible for creating these worker bundle files.

Step-by-Step Solution

Step 1: Ensure `vite-plugin-monaco-editor` is Correctly Configured

Make sure vite-plugin-monaco-editor is correctly set up in your vite.config.ts. You've already done this, but let's double-check:

// 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({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
    }),
  ],
  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'),
    },
  },
  worker: {
    format: 'es',
  },
});

Step 2: Check the Vite Build Output

Build your project:
```
npm run build
```
Check the dist directory: Navigate to the dist directory and ensure that the worker files (json.worker.bundle.js, css.worker.bundle.js, html.worker.bundle.js, ts.worker.bundle.js, editor.worker.bundle.js) are present.

Step 3: Serve the Correct Files

Ensure that the dist directory is being served correctly by Vite. If you are running the development server, Vite should handle this automatically. However, if you are serving the production build, make sure your server is correctly configured to serve static files from the dist directory.

Step 4: Verify Network Requests Again

Open the developer tools in your browser.
Go to the "Network" tab.
Filter by "JS" to see only JavaScript files.
Interact with your Monaco editor to trigger the loading of workers.
Look for requests to json.worker.bundle.js, css.worker.bundle.js, html.worker.bundle.js, ts.worker.bundle.js, and editor.worker.bundle.js.

If the files are still not being served correctly, it means they might not be generated, or there might be a misconfiguration in your Vite setup.

Additional Debugging

If the files are not being generated, you can log the Vite build process to see if there are any errors or missed steps. Add some logging in your Vite configuration:

// 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({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
    }),
  ],
  base: '/',
  build: {
    target: 'esnext',
    outDir: 'dist',
    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',
  },
  buildEnd() {
    console.log('Build finished!');
  },
});

Rebuild your project and check the logs for any issues.

By following these steps, you should be able to track down the issue and ensure that the worker files are correctly generated and served.

Understood. Let's focus on directly verifying the existence and correctness of the worker files without repeatedly checking the same configuration.

Step 1: Directly Check the Generated Files

Build the Project:

Run the build command to generate the output files.
```
npm run build
```
Inspect the dist Directory:

After the build completes, manually inspect the dist directory to check if the expected worker files are present.
- Navigate to the dist directory.
- Look for files named json.worker.bundle.js, css.worker.bundle.js, html.worker.bundle.js, ts.worker.bundle.js, editor.worker.bundle.js.

Step 2: Programmatically Verify the Files

If you want to automate this verification, you can write a simple Node.js script to check the existence of these files.

Create a script named verifyWorkers.js:

// verifyWorkers.js
const fs = require('fs');
const path = require('path');

const workerFiles = [
  'json.worker.bundle.js',
  'css.worker.bundle.js',
  'html.worker.bundle.js',
  'ts.worker.bundle.js',
  'editor.worker.bundle.js',
];

const distPath = path.resolve(__dirname, 'dist');

workerFiles.forEach(file => {
  const filePath = path.join(distPath, file);
  if (fs.existsSync(filePath)) {
    console.log(`Worker file exists: ${filePath}`);
  } else {
    console.error(`Worker file missing: ${filePath}`);
  }
});

Run this script after building your project:

node verifyWorkers.js

Step 3: Examine `vite-plugin-monaco-editor` Output

Ensure that vite-plugin-monaco-editor is indeed producing the output files. You can add logging to verify its activity.

Step 4: Check Network Requests

Once the files are verified to exist in the dist directory, start the Vite development server and check the network requests:

Start the Development Server:
```
npm run dev
```
Inspect Network Requests:
- Open the developer tools in your browser.
- Go to the "Network" tab.
- Filter by "JS" to see only JavaScript files.
- Interact with your Monaco editor to trigger the loading of workers.
- Look for requests to json.worker.bundle.js, css.worker.bundle.js, html.worker.bundle.js, ts.worker.bundle.js, and editor.worker.bundle.js.

Step 5: Ensure Correct Path in `MonacoEnvironment`

Double-check your MonacoEnvironment configuration to ensure it matches the paths where the worker files are generated.

// src/components/MonacoEditor.tsx
import React, { 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) {
    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';
    }
    console.log(`Loading worker for ${label}: ${workerUrl}`);
    return workerUrl;
  },
};

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

// ... rest of the component code

By following these steps, you can directly verify the existence and correctness of the worker files, ensuring that they are generated and served as expected.

It looks like none of the worker files are being generated in your dist directory, which is why you're seeing the HTML page instead of the JavaScript files. This indicates that the worker files are not being correctly bundled by Vite.

Let's take a step-by-step approach to resolve this issue.

Step 1: Check the Build Configuration

Ensure that the vite-plugin-monaco-editor plugin is correctly configured in your vite.config.ts. The configuration you provided looks correct, but let's focus on the specific part that should bundle the worker files.

Step 2: Inspect the Plugin Output

To better understand what's going wrong, let's add some debug logs to see if the plugin is being invoked correctly.

Step 3: Verify the Plugin Version

Ensure you are using a compatible version of vite-plugin-monaco-editor with your Vite setup. Check your package.json:

"dependencies": {
  "vite-plugin-monaco-editor": "^1.1.0",
  "monaco-editor": "^0.50.0",
  // other dependencies...
}

Step 4: Create a Minimal Reproduction

To isolate the issue, create a minimal reproduction of your setup:

Create a New Vite Project

npm create vite@latest my-monaco-project --template react
cd my-monaco-project
npm install

Install the Required Packages

npm install monaco-editor vite-plugin-monaco-editor

Set Up vite.config.ts

Replace the default vite.config.ts with the following:

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({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
    }),
  ],
  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: {
      'monaco-editor': path.resolve(__dirname, 'node_modules/monaco-editor'),
    },
  },
  worker: {
    format: 'es',
  },
});

Create a Simple Monaco Editor Component

Create src/MonacoEditor.tsx:

import React, { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';

(window as any).MonacoEnvironment = {
  getWorkerUrl: function (_moduleId, label) {
    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';
    }
    console.log(`Loading worker for ${label}: ${workerUrl}`);
    return workerUrl;
  },
};

const MonacoEditor = () => {
  const editorRef = useRef(null);

  useEffect(() => {
    if (editorRef.current) {
      monaco.editor.create(editorRef.current, {
        value: '// type your code...',
        language: 'javascript',
      });
    }
  }, []);

  return <div ref={editorRef} style={{ height: '500px' }} />;
};

export default MonacoEditor;

Add the Component to Your App

Edit src/App.tsx:

import React from 'react';
import MonacoEditor from './MonacoEditor';

function App() {
  return (
    <div className="App">
      <h1>Monaco Editor with Vite</h1>
      <MonacoEditor />
    </div>
  );
}

export default App;

Build the Project
```
npm run build
```
Check the dist Directory

Inspect the dist directory to ensure that the worker files are generated.

Step 5: Debugging Logs

If the issue persists, add logging to your Vite configuration script to ensure that the plugin is being invoked and the workers are being processed.

Step 6: Verify Network Requests

Start the development server:
```
npm run dev
```
Open your application in the browser and check the network requests following the previous steps.

By creating a minimal reproduction, you can isolate the issue and ensure that the worker files are correctly generated and served. If everything works in the minimal project but not in your main project, it indicates that the issue might be related to other parts of your configuration or build setup.
