emmet-monaco-es

Emmet Support for Monaco Editor, based on vscode-emmet-helper

Advantage

• Almost the same as VSCode's built-in emmet, integrated with completion provider
• Various languages support

Install

$ npm install emmet-monaco-es

Usage

NOTE

The emmet functionality was bound to language features not to a specific editor instance.

• emmetHTML works for HTML compatible languages, like PHP, for html only by default
• emmetCSS works for CSS compatible languages, like LESS / SCSS, for css only by default
• emmetJSX works for JSX compatible languages, like JavaScript / TypeScript / MDX, for javascript only by default

Follow this guide to make Monaco Editor support TSX

Initialize emmet should BEFORE all monaco editor instance creation

ESM

import { emmetHTML, emmetCSS, emmetJSX, expandAbbreviation, registerCustomSnippets } from 'emmet-monaco-es'

// `emmetHTML` , `emmetCSS` and `emmetJSX` are used the same way
const dispose = emmetHTML(
  // monaco-editor it self. If not provided, will use window.monaco instead.
  // This could make the plugin support both ESM and AMD loaded monaco-editor
  monaco,
  // languages needs to support html markup emmet, should be lower case.
  ['html', 'php'],
)

// run it if you want to dispose emmetHTML.
// NOTE: all languages specified will be disposed.
dispose()

// internal expand API, if you want to extend functionality with emmet
// check out the emmet repo https://github.com/emmetio/emmet for how to use it
expandAbbreviation('a', { type: 'markup', syntax: 'html' }) // <a href=""></a>
