[Monaco Editor](https://github.com/Microsoft/monaco-editor) for React. [![NPM version][npm-image]][npm-url] [![Downloads][downloads-image]][npm-url] ![Test](https://github.com/react-monaco-editor/react-monaco-editor/workflows/Test/badge.svg) [npm-url]: https://npmjs.org/package/react-monaco-editor [downloads-image]: http://img.shields.io/npm/dm/react-monaco-editor.svg [npm-image]: http://img.shields.io/npm/v/react-monaco-editor.svg

## Examples To build the examples locally, run: ```bash yarn cd example yarn yarn start ``` Then open `http://localhost:8886` in a browser. ## Installation ```bash yarn add react-monaco-editor ``` ## Using with Webpack ```js import React from 'react'; import { createRoot } from "react-dom/client"; import MonacoEditor from 'react-monaco-editor'; class App extends React.Component { constructor(props) { super(props); this.state = { code: '// type your code...', } } editorDidMount(editor, monaco) { console.log('editorDidMount', editor); editor.focus(); } onChange(newValue, e) { console.log('onChange', newValue, e); } render() { const code = this.state.code; const options = { selectOnLineNumbers: true }; return ( ); } } const container = document.getElementById('root'); const root = createRoot(container); root.render(); ``` Add the [Monaco Webpack plugin](https://github.com/Microsoft/monaco-editor-webpack-plugin) `monaco-editor-webpack-plugin` to your `webpack.config.js`: ```js const MonacoWebpackPlugin = require('monaco-editor-webpack-plugin'); module.exports = { plugins: [ new MonacoWebpackPlugin({ // available options are documented at https://github.com/microsoft/monaco-editor/blob/main/webpack-plugin/README.md#options languages: ['json'] }) ] }; ``` Sidenote: Monaco Editor uses CSS imports internally, so if you're using CSS Modules in your project - you're likely to get conflict by default. In order to avoid that - separate css-loader for app and monaco-editor package: ```js // Specify separate paths const path = require('path'); const APP_DIR = path.resolve(__dirname, './src'); const MONACO_DIR = path.resolve(__dirname, './node_modules/monaco-editor'); { test: /\.css$/, include: APP_DIR, use: [{ loader: 'style-loader', }, { loader: 'css-loader', options: { modules: true, namedExport: true, }, }], }, { test: /\.css$/, include: MONACO_DIR, use: ['style-loader', 'css-loader'], } ``` ## Properties All the properties below are optional. - `width` width of editor. Defaults to `100%`. - `height` height of editor. Defaults to `100%`. - `value` value of the auto created model in the editor. - `defaultValue` the initial value of the auto created model in the editor. - `language` the initial language of the auto created model in the editor. - `theme` the theme of the editor - `options` refer to [Monaco interface IStandaloneEditorConstructionOptions](https://microsoft.github.io/monaco-editor/docs.html#interfaces/editor.IStandaloneEditorConstructionOptions.html). - `overrideServices` refer to [Monaco Interface IEditorOverrideServices](https://microsoft.github.io/monaco-editor/docs.html#interfaces/editor.IEditorOverrideServices.html). It depends on Monaco's internal implementations and may change over time, check github [issue](https://github.com/Microsoft/monaco-editor/issues/935#issuecomment-402174095) for more details. - `onChange(newValue, event)` an event emitted when the content of the current model has changed. - `editorWillMount(monaco)` an event emitted before the editor mounted (similar to `componentWillMount` of React). - `editorDidMount(editor, monaco)` an event emitted when the editor has been mounted (similar to `componentDidMount` of React). - `editorWillUnmount(editor, monaco)` an event emitted before the editor unmount (similar to `componentWillUnmount` of React). ## Events & Methods Refer to [Monaco interface IEditor](https://microsoft.github.io/monaco-editor/typedoc/interfaces/editor.IEditor.html). The monaco interfaces available by import ```js import { monaco } from 'react-monaco-editor'; ``` ## Q & A ### I don't get syntax highlighting / autocomplete / validation. Make sure to use the [Monaco Webpack plugin](https://github.com/Microsoft/monaco-editor-webpack-plugin) or follow the [instructions on how to load the ESM version of Monaco](https://github.com/Microsoft/monaco-editor/blob/master/docs/integrate-esm.md). ### How to interact with the MonacoEditor instance Using the first parameter of `editorDidMount`, or using a `ref` (e.g. ``) after `editorDidMount` event has fired. Then you can invoke instance methods via `this.refs.monaco.editor`, e.g. `this.refs.monaco.editor.focus()` to focuses the MonacoEditor instance. ### How to get value of editor Using `this.refs.monaco.editor.getValue()` or via method of `Model` instance: ```js const model = this.refs.monaco.editor.getModel(); const value = model.getValue(); ``` ### Do something before editor mounted For example, you may want to configure some JSON schemas before editor mounted, then you can go with `editorWillMount(monaco)`: ```js class App extends React.Component { editorWillMount(monaco) { monaco.languages.json.jsonDefaults.setDiagnosticsOptions({ validate: true, schemas: [{ uri: "http://myserver/foo-schema.json", fileMatch: ['*'], schema: { type: "object", properties: { p1: { enum: [ "v1", "v2"] }, p2: { $ref: "http://myserver/bar-schema.json" } } } }] }); } render() { return ( ); } } ``` ### Use multiple themes [Monaco only supports one theme](https://github.com/Microsoft/monaco-editor/issues/338). ### How to use the diff editor ```js import React from 'react'; import { MonacoDiffEditor } from 'react-monaco-editor'; class App extends React.Component { render() { const code1 = "// your original code..."; const code2 = "// a different version..."; const options = { //renderSideBySide: false }; return ( ); } } ``` ### Usage with `create-react-app` The easiest way to use the `react-monaco-editor` with `create-react-app` is to use the [react-app-rewired](https://github.com/timarney/react-app-rewired) project. For setting it up, the following steps are required: 1. Install `react-app-rewired`: `npm install -D react-app-rewired` 2. Replace `react-scripts` by `react-app-rewired` in the scripts section of your `packages.json` 2. Create a `config-overrides.js` in the root directory of your project with the following content: ```javascript const MonacoWebpackPlugin = require('monaco-editor-webpack-plugin'); module.exports = function override(config, env) { config.plugins.push(new MonacoWebpackPlugin({ languages: ['json'] })); return config; } ``` For more information checkout the documentation of `react-app-rewired` [here](https://github.com/timarney/react-app-rewired). # License MIT, see the [LICENSE](/LICENSE.md) file for detail.
