Monaco Editor Webpack Loader Plugin

A plugin to simplify loading the Monaco Editor with webpack.


npm install monaco-editor-webpack-plugin


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

module.exports = {
  entry: './index.js',
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'app.js'
  plugins: [
    new MonacoWebpackPlugin()
  • index.js:
import * as monaco from 'monaco-editor';

monaco.editor.create(document.getElementById('container'), {
  value: 'console.log("Hello, world")',
  language: 'javascript'


Options can be passed in to MonacoWebpackPlugin. They can be used to generate a smaller editor bundle by selecting only certain languages or only certain editor features:

  • output (string) - custom output path for worker scripts, relative to the main webpack output.path.
    • default value: ''.
  • languages (string[]) - include only a subset of the languages supported.
    • default value: ['bat', 'coffee', 'cpp', 'csharp', 'csp', 'css', 'dockerfile', 'fsharp', 'go', 'handlebars', 'html', 'ini', 'java', 'json', 'less', 'lua', 'markdown', 'msdax', 'mysql', 'objective', 'pgsql', 'php', 'postiats', 'powershell', 'pug', 'python', 'r', 'razor', 'redis', 'redshift', 'ruby', 'sb', 'scss', 'solidity', 'sql', 'swift', 'typescript', 'vb', 'xml', 'yaml'].
  • features (string[]) - include only a subset of the editor features.
    • default value: ['accessibilityHelp', 'bracketMatching', 'caretOperations', 'clipboard', 'codelens', 'colorDetector', 'comment', 'contextmenu', 'coreCommands', 'cursorUndo', 'dnd', 'find', 'folding', 'format', 'gotoDeclarationCommands', 'gotoDeclarationMouse', 'gotoError', 'gotoLine', 'hover', 'inPlaceReplace', 'inspectTokens', 'iPadShowKeyboard', 'linesOperations', 'links', 'multicursor', 'parameterHints', 'quickCommand', 'quickFixCommands', 'quickOutline', 'referenceSearch', 'rename', 'smartSelect', 'snippets', 'suggest', 'toggleHighContrast', 'toggleTabFocusMode', 'transpose', 'wordHighlighter', 'wordOperations'].
