How to use monaco-editor in

angular? The following article records the use of monaco-editor in angular that was used in a recent business. I hope it will be helpful to everyone!

Installation dependencies

In angular12 and before you can choose

• monaco-editor
• ngx-monaco-editor

This is no problem but if you use a higher version of angular, you will have to install ngx-monaco-editor using npm. Report an error. [Related tutorial recommendation: "angularjs video tutorial"]

Because the original author seems to have stopped maintaining this library, the final support remains at the angular12 version

Of course you can choose to use --force or --legacy-peer-deps as prompted to solve the problem

But in order to eliminate/avoid some hidden problems, I added it to the original author's Basically, the framework's angular support has been upgraded to 14 and will be updated continuously

npmwww.npmjs.com/package/@ri…

Of course you can also choose to move the author's source code into your own local code, which is completely fine

• base-editor.ts introduces monaco-editor
• config.ts
• diff-editor.component.ts
• editor.component.ts
• editor.module.ts
• types.ts

You only need to move the lib directory Just download the six files and use them as a module in your own project

Use

In fact, all APIs are It can be found in the file

editor.api.d.ts

// 在这个editor下就可以找到所有TS类型 import { editor } from 'monaco-editor';

The following is a record of the commonly used

1, settings

// eg export const READ_EDITOR_OPTIONS: editor.IEditorOptions = { readOnly: true, automaticLayout: false, minimap: { enabled: false, }, renderFinalNewline: false, scrollbar: { vertical: 'visible', }, mouseWheelZoom: true, contextmenu: false, fontSize: 16, scrollBeyondLastLine: false, smoothScrolling: true, cursorWidth: 0, renderValidationDecorations: 'off', colorDecorators: false, hideCursorInOverviewRuler: true, overviewRulerLanes: 0, overviewRulerBorder: false, };

2, and acquisition editor example

  public initViewEditor(editor: editor.ICodeEditor): void { // 这个editor就是实例 // 下面方法中的editor就是这里的editor this.editor = editor }

3. Get the current cursor position

editor.getPosition()

4. Get the text currently selected by the mouse

editor.getModel().getValueInRange(editor.getSelection());

5. Modify the cursor position

editor.setPosition({ column: 1, lineNumber: 1, });

6 , scroll the specified line to the middle of the visual area

editor.revealLineInCenter(1);

7, bind events

editor.onMouseDown(event => { // do something }); editor.onKeyDown(event => { // do something });

8, save/restore snapshot

const snapshot = editor.saveViewState(); editor.restoreViewState(snapshot);

9, block an event

// eg 组件默认的搜索快捷键 function isMac() { return /macintosh|mac os x/i.test(navigator.userAgent); } editor.onKeyDown(event => { if ( (isMac() && event.browserEvent.key === 'f' && event.metaKey) || (!isMac() && event.browserEvent.key === 'f' && event.ctrlKey) ) { event.preventDefault(); event.stopPropagation(); } });
