electron react离线使用monaco-editor

1.安装@monaco-editor/react和monaco-editor

pnpm i @monaco-editor/react

pnpm i monaco-editor

2.引入并做monaco-editor离线配置

import Editor, { DiffEditor, useMonaco, loader } from '@monaco-editor/react'

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();},
};
loader.config({ monaco })
loader.init().then(/* ... */);

3.react中使用

function App(): JSX.Element {const editorRef = useRef(null)function handleEditorDidMount(editor, monaco) {editorRef.current = editor}function showValue() {alert(editorRef.current.getValue())}return (<><Editorwidth="600px"height="30vh"defaultLanguage="javascript"defaultValue="// some comment"onMount={handleEditorDidMount}/>
<div className="actions"><div className="action"><a target="_blank" rel="noreferrer" onClick={showValue}>Show value</a></div></div></>)
}

export default App

4.完整代码示例

import Versions from './components/Versions'
import electronLogo from './assets/electron.svg'
import { useRef } from 'react'
import Editor, { DiffEditor, useMonaco, loader } from '@monaco-editor/react'
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();},
};
loader.config({ monaco })
loader.init().then(/* ... */);function App(): JSX.Element {const ipcHandle = (): void => window.electron.ipcRenderer.send('ping')const editorRef = useRef(null)function handleEditorDidMount(editor, monaco) {editorRef.current = editor}function showValue() {alert(editorRef.current.getValue())}return (<><img alt="logo" className="logo" src={electronLogo} /><Editorwidth="600px"height="30vh"defaultLanguage="javascript"defaultValue="// some comment"onMount={handleEditorDidMount}/><div className="actions"><div className="action"><a target="_blank" rel="noreferrer" onClick={showValue}>Show value</a></div><div className="action"><a target="_blank" rel="noreferrer" onClick={ipcHandle}>Send IPC</a></div></div><Versions></Versions></>)
}export default App

5.monaco-editor离线配置官方说明

loader-config

该库导出（命名）名为loader实用程序。基本上，它是@monaco-editor/loader的引用。默认情况下， monaco文件是从CDN下载的。有能力改变这种行为，以及有关monaco AMD加载程序的其他事情。我们有一个默认的配置文件，您可以通过以下方式修改：

import { loader } from '@monaco-editor/react';// you can change the source of the monaco files
loader.config({ paths: { vs: '...' } });// you can configure the locales
loader.config({ 'vs/nls': { availableLanguages: { '*': 'de' } } });

// or

loader.config({paths: {vs: '...',},'vs/nls': {availableLanguages: {'*': 'de',},},
});

使用monaco-editor作为 npm 包

从v4.4.0版本开始，可以将monaco-editor作为npm包使用；从node_modules导入它并将monaco源包含到您的包中（而不是使用 CDN）。要使其正常工作，您可以执行以下操作：

import * as monaco from 'monaco-editor';
import { loader } from '@monaco-editor/react';loader.config({ monaco });// ...

注意：您应该意识到，这可能需要额外的webpack插件，例如monaco-editor-webpack-plugin ，否则可能无法在CRA生成的应用程序中使用而不弹出它们。

如果你使用Vite ，你需要这样做：

import { loader } from '@monaco-editor/react';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();},
};loader.config({ monaco });loader.init().then(/* ... */);
