• monaco-editor: 0.15+

Demo

See: https://ng-monaco-editor.js.org or https://ng-monaco-editor.netlify.app

Configure monaco-editor library assets

It's supported to load monaco-editor with AMD or ESM mode.

If you'd like to use AMD mode, you have to make sure your Angular application could have access to the monaco-editor library assets via AMD. If you are using Angular CLI to bootstrap your app, you could add the following:

{
  "assets": [
    "src/favicon.ico",
    "src/assets",

    {
      "glob": "**/*",
      "input": "node_modules/monaco-editor/min/vs",
      "output": "/lib/vs"
    }
  ]
}

Load ng-monaco-editor module

Most of the time, you should configure the module at the root module.

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    FormsModule,
    MonacoEditorModule.forRoot({
      /**
       * optional, load monaco by yourself, you'd prefer loading esm for example
       */
      dynamicImport: () => import('monaco-editor'),

      /**
       * optional, use amd loader to load monaco if present, lower priority than `dynamicImport`
       *
       * Angular CLI currently does not handle assets with hashes. We manage it by manually adding
       * version numbers to force library updates:
       */
      baseUrl: 'lib/v1',

      defaultOptions: {},
    }),
  ],
  providers: [
    {
      // Optional:
      // You could also override the default MonacoEditor provider.
      // If you plan to do so, I recommend you to read through the source code.
      provide: MonacoProviderService,
      useClass: CustomMonacoProviderService,
    },
  ],
  bootstrap: [AppComponent],
})
export class AppModule {}

Usage example

Please refer to the storybook (stories/**/*.stories.ts).

This module provide three usages:

1. ng-monaco-editor component
2. ng-monaco-diff-editor component
3. ngCodeColorize directive

Note, if the height of ng-monaco-editor/ng-monaco-diff-editor is too small, you may have to resize it yourself. This is a limitation and by design that how monaco-editor works.
