## Integrating the ESM version of the Monaco Editor ### Using webpack Here is the most basic script that imports the editor using ESM with webpack. More self-contained samples are available at [monaco-editor-samples](https://github.com/Microsoft/monaco-editor-samples). * `index.js` ```js import * as monaco from 'monaco-editor'; // Since packaging is done by you, you need // to instruct the editor how you named the // bundles that contain the web workers. self.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') { return './ts.worker.bundle.js'; } return './editor.worker.bundle.js'; } } monaco.editor.create(document.getElementById('container'), { value: [ 'function x() {', '\tconsole.log("Hello world!");', '}' ].join('\n'), language: 'javascript' }); ``` * `webpack.config.js`: ```js const path = require('path'); const webpack = require('webpack'); module.exports = { entry: { "app": './index.js', // Package each language's worker and give these filenames in `getWorkerUrl` "editor.worker": 'monaco-editor/esm/vs/editor/editor.worker.js', "json.worker": 'monaco-editor/esm/vs/language/json/json.worker', "css.worker": 'monaco-editor/esm/vs/language/css/css.worker', "html.worker": 'monaco-editor/esm/vs/language/html/html.worker', "ts.worker": 'monaco-editor/esm/vs/language/typescript/ts.worker', }, output: { filename: '[name].bundle.js', path: path.resolve(__dirname, 'dist') }, module: { rules: [{ test: /\.css$/, use: [ 'style-loader', 'css-loader' ] }] }, plugins: [ // Ignore require() calls in vs/language/typescript/lib/typescriptServices.js new webpack.IgnorePlugin( /^((fs)|(path)|(os)|(crypto)|(source-map-support))$/, /vs\/language\/typescript\/lib/ ) ] }; ```
