Install with the command:

npm i @julceswhat/angular5-monaco-editor-loader

An easy to use Monaco Editor Loader Service for Angular 5! Just add *loadMonacoEditor in your HTML Element, and you don't have to worry about timing issues!

1 Prerequisites

1. Make sure that you are serving Monaco Editor in /assets/monaco-editor/vs

2. If you are using straight app.component then DO NOT USE the directive. Instead use the following code in app.component.ts:

  constructor(private monaco: MonacoEditorLoaderService) {

  }

  this.monaco.isMonacoLoaded.subscribe(value => {
      if (value) {
        // Initialize monaco...
      }
    })

3. If you are creating a component on top of monaco, then just use the directive *loadMonacoEditor inside your component's HTML

2 Using webpack

If you are using Webpack do the following:

plugins: [
     new CopyWebpackPlugin([
         {
             from: 'node_modules/monaco-editor/min/vs',
             to: './src/assets/monaco',
         }
     ]),
 ],

3 Using Angular CLI

1. For development modify .angular-cli.json to the following:

"assets": [
       {
         "glob": "**/*",
         "input": "../node_modules/monaco-editor/dev/",
         "output": "./assets/monaco-editor/"
       },
       {
         "glob": "favicon.ico",
         "input": "./",
         "output": "./"
       }
     ]

2. For production modify .angular-cli.json to the following: Modify .angular-cli.json to the following:

"assets": [
       {
         "glob": "**/*",
         "input": "../node_modules/monaco-editor/min/",
         "output": "./assets/monaco-editor/"
       },
       {
         "glob": "**/*",
         "input": "../node_modules/monaco-editor/min-maps/",
         "output": "./assets/min-maps/"
       },
       {
         "glob": "favicon.ico",
         "input": "./",
         "output": "./"
       }
     ]

3. Add /// <reference path="./../node_modules/monaco-editor/monaco.d.ts" /> in you typings.d.ts file to remove monaco editor undefined errors and allow compilation.

4 Usage

1. In your component's module or app module. Import the following:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { MonacoEditorLoaderModule, MonacoEditorLoaderService } from '@julceswhat/angular5-monaco-editor-loader';

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

@NgModule({
  declarations: [
    AppComponent,
    MonacoEditorComponent
  ],
  imports: [
    BrowserModule,
    MonacoEditorLoaderModule <-- Insert this>
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

2. Just add *loadMonacoEditor, so with your custom component where you plan to create your own monaco component. Just add the following:

<monaco-editor *loadMonacoEditor></monaco-editor>

3. And in my custom component where I want to host Monaco Editor I just do the following like I expect the Monaco library to be loaded at this point:

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

@Component({
  selector: 'monaco-editor',
  templateUrl: './monaco-editor.component.html',
  styleUrls: ['./monaco-editor.component.css']
})
export class MonacoEditorComponent implements OnInit {

  constructor() { }

  ngOnInit() {
    monaco.languages.typescript.javascriptDefaults.setDiagnosticsOptions({
      noSemanticValidation: true,
      noSyntaxValidation: false
    });

    // compiler options
    monaco.languages.typescript.javascriptDefaults.setCompilerOptions({
      target: monaco.languages.typescript.ScriptTarget.ES2016,
      allowNonTsExtensions: true
    });

    // extra libraries
    monaco.languages.typescript.javascriptDefaults.addExtraLib([
      'declare class Facts {',
      '    /**',
      '     * Returns the next fact',
      '     */',
      '    static next():string',
      '}',
    ].join('\n'), 'filename/facts.d.ts');

    var jsCode = [
      '"use strict";',
      '',
      "class Chuck {",
      "    greet() {",
      "        return Facts.next();",
      "    }",
      "}"
    ].join('\n');

    monaco.editor.create(document.getElementById("container"), {
      value: jsCode,
      language: "javascript"
    });
  }

}

4. And that's it! No timeouts! No then! It just goes with the correct flow in Angular!

5 Running the demo app

Make sure you have Angular CLI installed!

1. Clone this repository
2. cd demo
3. npm install
4. ng serve

6 Motivation

I wanted to use Monaco Editor with my Angular 5 project, but couldn't find any library that would help me with this. Since I couldn't find anything, I decided to refactor a library that worked for previous Angular versions.

Most of the code that was found here just wasn't working with Angular 5.

Previous versions

• Angular v4 & Angular v2
