Usage

import { loadWASM } from 'onigasm' // peer dependency of 'monaco-textmate'
import { Registry } from 'monaco-textmate' // peer dependency
import { wireTmGrammars } from 'monaco-editor-textmate'
 
export async function liftOff() {
    await loadWASM(`path/to/onigasm.wasm`) // See https://www.npmjs.com/package/onigasm#light-it-up
 
    const registry = new Registry({
        getGrammarDefinition: async (scopeName) => {
            return {

    grammars.set('html', 'text.html.basic')
    grammars.set('typescript', 'source.ts')
 
    await wireTmGrammars(monaco, registry, grammars)
 
    var editor = monaco.editor.create(document.getElementById('container'), {
        value: [
            'html, body {',
            '    margin: 0;',
            '}'
        ].join('\n'),
        language: 'css' // this won't work out of the box, see below for more info
    })
}

Limitation

monaco-editor distribution comes with built-in tokenization support for few languages. Because of this monaco-editor-textmate cannot be used with monaco-editor without some modification, see explanation of this problem here.

Solution

To get monaco-editor-textmate working with monaco-editor, you're advised to use Webpack with monaco-editor-webpack-plugin which allows you to control which of "built-in" languages should monaco-editor use/bundle, leaving the rest. With that control you must exclude any/all languages for which you'd like to use TextMate grammars based tokenization instead.
