Using this Module you can utilize the Monaco Editor as an Angular Component. Feel free to contribute, raise feature requests and make it better.

Supports all the options available in monaco-editor Monaco Editor Options

Setup

Installation

Install from npm repository:

npm install ngx-monaco-editor --save

For angular version 5 use v5.x.x

npm install ngx-monaco-editor@5.0.0 --save

Add the glob to assets in .angular-cli.json (to make monaco-editor lib available to the app):

{
  "apps": [
    {
      "assets": [
        { "glob": "**/*", "input": "../node_modules/ngx-monaco-editor/assets/monaco", "output": "./assets/monaco/" }
      ],
      ...
    }
    ...
  ],
  ...
}

Sample

Include MonacoEditorModule in Main Module and Feature Modules where you want to use the editor component.(eg: app.module.ts):

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';

import { AppComponent } from './app.component';
import { MonacoEditorModule } from 'ngx-monaco-editor';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    MonacoEditorModule.forRoot() // use forRoot() in main app module only.
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {
}

Create Editor options in component.(eg: app.component.ts)

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent {
  editorOptions = {theme: 'vs-dark', language: 'javascript'};
  code: string= 'function x() {\nconsole.log("Hello world!");\n}';
}

Include editor in html with options and ngModel bindings.(eg: app.component.html)

<ngx-monaco-editor [options]="editorOptions" [(ngModel)]="code"></ngx-monaco-editor>

Include diff-editor in html with options.(eg: app.component.html)

<ngx-monaco-diff-editor [options]="options" [originalModel]="originalModel" [modifiedModel]="modifiedModel"></ngx-monaco-diff-editor>
import { Component } from '@angular/core';
import { DiffEditorModel } from 'ngx-monaco-editor';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html'
})
export class AppComponent {
  options = {
    theme: 'vs-dark'
  };
  originalModel: DiffEditorModel = {
    code: 'heLLo world!',
    language: 'text/plain'
  };

  modifiedModel: DiffEditorModel = {
    code: 'hello orlando!',
    language: 'text/plain'
  };
}

Styling

Add class to editor tag. (eg. class="my-code-editor")

<ngx-monaco-editor class="my-code-editor" [options]="editorOptions" [(ngModel)]="code"></ngx-monaco-editor>

Add styling in css/scss file:

.my-code-editor {
  .editorContainer {
    height: calc(100vh - 100px);
  }
}

Set automaticLayout option to adjust editor size dynamically. Recommended when using in modal dialog or tabs where editor is not visible initially.

Events

Output event (onInit) expose editor instance that can be used for performing custom operations on the editor.

<ngx-monaco-editor [options]="editorOptions" [(ngModel)]="code" (onInit)="onInit($event)"></ngx-monaco-editor>
export class AppComponent {
  editorOptions = {theme: 'vs-dark', language: 'javascript'};
  code: string= 'function x() {\nconsole.log("Hello world!");\n}';
  onInit(editor) {
      let line = editor.getPosition();
      console.log(line);
    }
}

Configurations

forRoot() method of MonacoEditorModule accepts config of type NgxMonacoEditorConfig.

import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { BrowserModule } from '@angular/platform-browser';

import { MonacoEditorModule, NgxMonacoEditorConfig } from 'ngx-monaco-editor';
import { AppComponent } from './app.component';

const monacoConfig: NgxMonacoEditorConfig = {
  baseUrl: 'app-name/assets', // configure base path for monaco editor
  defaultOptions: { scrollBeyondLastLine: false }, // pass default options to be used
  onMonacoLoad: () => { console.log((<any>window).monaco); } // here monaco object will be available as window.monaco use this function to extend monaco editor functionality.
};

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    MonacoEditorModule.forRoot(monacoConfig)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {
}

Configure JSON Defaults

onMonacoLoad property of NgxMonacoEditorConfig can be used to configure JSON default.

import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { BrowserModule } from '@angular/platform-browser';

import { MonacoEditorModule, NgxMonacoEditorConfig } from 'ngx-monaco-editor';
import { AppComponent } from './app.component';

const monacoConfig: NgxMonacoEditorConfig = {
  onMonacoLoad: () => { 
    const id = "foo.json";
    monaco.languages.json.jsonDefaults.setDiagnosticsOptions({
      validate: true,
      schemas: [{
        uri: "http://myserver/foo-schema.json",
        fileMatch: [id],
        schema: {
          type: "object",
          properties: {
            p1: {
              enum: [ "v1", "v2"]
            },
            p2: {
              $ref: "http://myserver/bar-schema.json"
            }
          }
        }
      },{
        uri: "http://myserver/bar-schema.json",
        fileMatch: [id],
        schema: {
          type: "object",
          properties: {
            q1: {
              enum: [ "x1", "x2"]
            }
          }
        }
      }]
    });
  } 
};

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    MonacoEditorModule.forRoot(monacoConfig)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {
}

Now pass model config of type NgxEditorModel to Editor Component

@Component({
  selector: 'app-root',
  template: `<ngx-monaco-editor [options]="options" [model]="model"></ngx-monaco-editor>`,
  styles: []
})
export class AppComponent {
  options = {
    theme: 'vs-dark'
  };
  
  jsonCode = [
    '{',
    '    "p1": "v3",',
    '    "p2": false',
    '}'
  ].join('\n');

  model: NgxEditorModel = {
    value: this.jsonCode,
    language: 'json',
    uri: 'foo.json'
  };
}
