Monaco Editor Vue3

Monaco Editor is the code editor that powers VS Code, now it's available as a Vue3 component <MonacoEditor> thanks to this project.

Install

pnpm install monaco-editor-vue3

Or

yarn add monaco-editor-vue3

Or

npm i monaco-editor-vue3

Usage

Use ESM version with webpack

Use monaco-editor-webpack-plugin:

// webpack.config.js
const MonacoEditorPlugin = require('monaco-editor-webpack-plugin')

module.exports = {
  plugins: [
    new MonacoEditorPlugin({
      // https://github.com/Microsoft/monaco-editor-webpack-plugin#options
      // Include a subset of languages support
      // Some language extensions like typescript are so huge that may impact build performance
      // e.g. Build full languages support with webpack 4.0 takes over 80 seconds
      // Languages are loaded on demand at runtime
      languages: ['javascript', 'css', 'html', 'typescript']
    })
  ]
}

Then use the component:

<template>
  <MonacoEditor
    theme="vs"
    :options="options"
    language="javascript"
    :width="800"
    :height="800"
    :diffEditor="true"
    :original="original"
    v-model:value="value"
  ></MonacoEditor>
</template>

<script>
import MonacoEditor from 'monaco-editor-vue3'

export default {
  components: {
    MonacoEditor
  },

  data() {
    return {
      code: 'const noop = () => {}'
    }
  }
}
</script>

<style>
.editor {
  width: 600px;
  height: 800px;
}
</style>
