 ### Using webpack

 Then, simply run `sh ./build_workers.sh && parcel index.html`. This builds the workers into the same directory as your main bundle (usually `./dist`). If you want to change the `--out-dir` of the workers, you must change the paths in `index.js` to reflect their new location.
 
 *note - the `getWorkerUrl` paths are relative to the build directory of your src bundle*

+### Using Vite
+
+Adding monaco editor to [Vite](https://vitejs.dev/) is simple since it has built-in support for web workers. You only need to implement the `getWorker` function (NOT the `getWorkerUrl`) to use Vite's output ([Source](https://github.com/vitejs/vite/discussions/1791#discussioncomment-321046)):

+```js
+import * as monaco from 'monaco-editor'
+import editorWorker from 'monaco-editor/esm/vs/editor/editor.worker?worker'
+import jsonWorker from 'monaco-editor/esm/vs/language/json/json.worker?worker'
+import cssWorker from 'monaco-editor/esm/vs/language/css/css.worker?worker'
+import htmlWorker from 'monaco-editor/esm/vs/language/html/html.worker?worker'
+import tsWorker from 'monaco-editor/esm/vs/language/typescript/ts.worker?worker'
+
+self.MonacoEnvironment = {
+  getWorker(_, label) {
+    if (label === 'json') {
+      return new jsonWorker()
+    }
+    if (label === 'css' || label === 'scss' || label === 'less') {
+      return new cssWorker()
+    }
+    if (label === 'html' || label === 'handlebars' || label === 'razor') {
+      return new htmlWorker()
+    }
+    if (label === 'typescript' || label === 'javascript') {
+      return new tsWorker()
+    }
+    return new editorWorker()
+  }
