The error TypeError: monacoEditorPlugin is not a function suggests that the monacoEditorPlugin import in your vite.config.ts is not being handled correctly. This might be due to how ES module imports are being interpreted.

Since monacoEditorPlugin is being exported as a default function, you should ensure it's correctly imported in your vite.config.ts. Here’s how you can fix this:

Ensure you import the default export properly:

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

console.log('monacoEditorPlugin:', monacoEditorPlugin);

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin({ languageWorkers: ['typescript', 'json', 'html', 'css'] }), // Use the function 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'),
    },
  },
});

1. Default Import: Ensure you are importing the default export monacoEditorPlugin correctly without using braces {}.
2. Function Call: Ensure you are calling the monacoEditorPlugin function with the appropriate options.

This should resolve the error and allow Vite to correctly load the plugin.

It seems that the import/export discrepancy is still causing issues. Given that monacoEditorPlugin is both the default export and has named properties, we should handle this case carefully.

Let's try a combination approach to ensure we are importing monacoEditorPlugin correctly:

Since there seems to be a conflict with how the module is being imported, we can try using require to import it, which might circumvent the issue:

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
// Use require to import the plugin
const monacoEditorPlugin = require('vite-plugin-monaco-editor');

// or Use ESM import
// import * as monacoEditorPlugin from 'vite-plugin-monaco-editor'; 

console.log('monacoEditorPlugin:', monacoEditorPlugin);

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin.default({ languageWorkers: ['typescript', 'json', 'html', 'css'] }), // Use the default function
  ],
  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'),
    },
  },
});

1. Using require: The require statement might help avoid the issues related to the mixed module system.
2. Access Default Export: Use monacoEditorPlugin.default to access the default export function.

If this doesn't work, you can also try the ESM approach with import * as monacoEditorPlugin from 'vite-plugin-monaco-editor'; and refer to monacoEditorPlugin.default.

Ensure that you are using compatible versions of vite, vite-plugin-monaco-editor, and typescript. Sometimes, mismatched versions can cause import/export issues.

Sometimes clearing the cache and reinstalling dependencies can resolve unexpected issues:

rm -rf node_modules
rm yarn.lock
yarn install

Try these steps and see if it resolves the monacoEditorPlugin is not a function error.

The error Dynamic require of "vite-plugin-monaco-editor" is not supported indicates that dynamic require calls are not compatible with the ES module system that Vite uses.

Let's try the ESM approach more carefully:

Use the ESM import and access the default export:

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import path from 'path';
import * as monacoEditorPlugin from 'vite-plugin-monaco-editor'; // Import all as monacoEditorPlugin

console.log('monacoEditorPlugin:', monacoEditorPlugin);

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPlugin.default({ languageWorkers: ['typescript', 'json', 'html', 'css'] }), // Access the default function
  ],
  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'),
    },
  },
});

Double-check the vite-plugin-monaco-editor package to ensure it exports correctly. You can do this by inspecting the node_modules/vite-plugin-monaco-editor/dist/index.js file and verifying that it has a default export.

If you haven't already, clear the cache and reinstall dependencies:

rm -rf node_modules
rm yarn.lock
yarn install

This should help Vite resolve the plugin correctly. If you're still facing issues, we might need to consider a workaround or further inspect the vite-plugin-monaco-editor package for compatibility issues.

Given the structure of the monacoEditorPlugin object, it seems like the actual monacoEditorPlugin function is nested under the default property. This indicates some sort of double-wrapping issue.

Let's directly access the nested function:

You need to adjust the import to correctly access the nested function:

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

// Access the actual function nested under default
const monacoEditorPluginFunction = monacoEditorPlugin.default.default;

console.log('monacoEditorPlugin:', monacoEditorPlugin);

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginFunction({ languageWorkers: ['typescript', 'json', 'html', 'css'] }), // Use the nested function
  ],
  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'),
    },
  },
});

1. Access Nested Function: The monacoEditorPlugin seems to have a nested default function. We extract it using monacoEditorPlugin.default.default.
2. Use the Correct Function: Use this extracted function in the Vite config.

You can confirm this by logging the structure of monacoEditorPlugin to ensure it matches the expected nested structure:

console.log('monacoEditorPlugin:', monacoEditorPlugin);
console.log('monacoEditorPlugin.default:', monacoEditorPlugin.default);
console.log('monacoEditorPlugin.default.default:', monacoEditorPlugin.default.default);

This should help in identifying the correct function to use.

Great to hear that you got it to work! Let's break down the issue and why it was difficult to troubleshoot:

1. Module Export Structure:

   • The vite-plugin-monaco-editor package has a unique export structure where the actual plugin function is nested under multiple layers.
   • This nested structure can be confusing because it requires accessing the function via default.default.

2. ES Modules and CommonJS Interoperability:

   • Mixing ES Modules (import) and CommonJS (require) can lead to unexpected issues, particularly with deeply nested exports.
   • Vite uses ES Modules, but some packages might be authored in CommonJS, causing compatibility issues.

3. TypeScript and Type Imports:

   • TypeScript's type imports (import { type IMonacoEditorOpts }) need to be carefully handled alongside actual value imports.
   • Ensuring that the type and value imports align correctly can be tricky with complex module structures.

1. Misleading Error Messages:

   • Errors like monacoEditorPlugin is not a function can be misleading because they don't indicate the nested nature of the export.
   • This can lead to multiple attempts to import and access the function in different ways.

2. Limited Documentation:

   • The documentation for the specific structure of the vite-plugin-monaco-editor might not be clear or detailed enough.
   • Community discussions (like the GitHub issue you found) often provide insights that are not immediately obvious from official documentation.

3. Trial and Error:

   • The troubleshooting process involved multiple attempts with different import styles (default, * as, require).
   • Each attempt needs to be carefully validated, adding to the complexity and time required.

1. Inspect Module Structure:

   • Use console.log to inspect the structure of imported modules early in the troubleshooting process.
   • This can provide immediate insights into how the module is structured and how it should be accessed.

2. Refer to Community Discussions:

   • Look for GitHub issues, Stack Overflow discussions, and other community resources related to the package you are using.
   • These discussions often contain practical solutions and workarounds.

3. Understand ES Module and CommonJS Compatibility:

   • Familiarize yourself with the differences and interoperability between ES Modules and CommonJS.
   • This knowledge can help you anticipate and resolve issues related to module imports and exports.

4. Check for Updates and Documentation:

   • Ensure you are using the latest version of the package, as updates might resolve known issues.
   • Check the official documentation and release notes for any changes related to module exports.

The problem was primarily due to the nested export structure of the vite-plugin-monaco-editor and the complexities of ES Module and CommonJS interoperability. By inspecting the module structure early, referring to community discussions, and understanding module compatibility, you can streamline the troubleshooting process in the future.

The misleading error message monacoEditorPlugin is not a function stemmed from how the module was being imported and accessed. Let's break down the sources of confusion:

1. Nested Export Structure:

   • The vite-plugin-monaco-editor module exports a function that is nested under multiple layers. When you try to access it directly without navigating through these layers, JavaScript throws an error because the accessed property is not a function.

2. Default Export Handling:

   • ES Modules handle default exports differently from CommonJS. The default export in ES Modules can sometimes wrap the actual export, leading to situations where you have to access default.default.

When you tried:

import monacoEditorPlugin from 'vite-plugin-monaco-editor';
monacoEditorPlugin({ ... }); // This causes the error

The error occurred because monacoEditorPlugin was not directly a function but an object containing the function. Hence, JavaScript threw TypeError: monacoEditorPlugin is not a function.

The correct way to access the function was:

import monacoEditorPlugin from 'vite-plugin-monaco-editor';
const monacoEditorPluginDefault = (monacoEditorPlugin as any).default.default;
monacoEditorPluginDefault({ ... });

Here, monacoEditorPlugin is an object, and the actual function is nested under default.default.

1. Lack of Clarity in Error Message:

   • The error message monacoEditorPlugin is not a function does not indicate that there is a nested structure. It simply states that the accessed entity is not a function, which can be vague.

2. Complex Export Structure:

   • The nested structure default.default is not immediately obvious, especially if the module documentation does not explicitly mention it.

3. ES Module and CommonJS Interop:

   • The differences in how ES Modules and CommonJS exports are handled can result in unexpected structures. Vite, being an ES Module system, might wrap CommonJS exports in a way that necessitates accessing nested properties.

1. Inspect Imports:

   • Use console.log to inspect the structure of the imported module. For example:

     import monacoEditorPlugin from 'vite-plugin-monaco-editor';
     console.log(monacoEditorPlugin);

   • This helps in understanding what exactly is being imported.

2. Refer to Package Documentation and Issues:

   • Look for any notes on module exports and common issues in the documentation or community issues pages, like GitHub.

3. Understand Module Wrapping:

   • Be aware that ES Modules might wrap CommonJS exports, leading to nested structures.

By following these steps, you can better diagnose and resolve similar issues in the future.

The error Unexpected token '<' in the context of loading Monaco Editor workers typically suggests that the worker files are being served incorrectly, often as HTML instead of JavaScript. This can happen if the paths to the worker files are not correctly resolved or if there's an issue with the Vite configuration for handling these workers.

1. Ensure Worker Paths are Correct: Make sure the paths to the worker files are correctly configured in vite.config.ts.

2. Correct Vite Configuration for Workers: The vite-plugin-monaco-editor should automatically handle worker paths, but you may need to ensure the configuration is correct.

3. Check Rollup and Vite Configuration: Ensure the rollupOptions in your Vite configuration are properly set up to handle the Monaco Editor workers.

Here's a detailed approach to ensure the configuration is correct:

Ensure the worker paths are correctly specified:

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

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

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'),
    },
  },
});

Check if the monaco-editor package and vite-plugin-monaco-editor are correctly installed and up to date. This ensures compatibility.

If the above steps do not resolve the issue, you can try handling the worker imports manually by customizing the Vite configuration further.

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

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

export default defineConfig({
  plugins: [
    react(),
    monacoEditorPluginDefault({
      languageWorkers: ['typescript', 'json', 'html', 'css'],
    }),
  ],
  base: '/',

Finally, clear your Vite cache and rebuild the project to ensure all configurations are correctly applied:

rm -rf node_modules
rm yarn.lock
yarn install
yarn dev
