Hooks

useMonaco use @monaco-editor/loader to load monaco-editor from the CDN.

<template>
  <div ref="containerRef"></div>
</template>

<script lang="ts" setup>
import { onUnmounted } from 'vue'
import { useMonaco, watchEffect, nextTick } from '@guolao/vue-monaco-editor'

const containerRef = ref()
const { monacoRef, unload } = useMonaco()

// watch once
const stop = watchEffect(() => {
  if (monacoRef.value && containerRef.value) {
    nextTick(() => stop())
    monacoRef.value.editor.create(containerRef.value, { ... })
  }
})

/*
  When the component will be unmount,
  If the monaco instance is not successfully loaded,
  You need to manually unload.
*/
onUnmounted(() => !monacoRef.value && unload())
</script>

CDN

vue-monaco-editor use @monaco-editor/loader to load the monaco-editor from the CDN(the loading process of loader is asynchronous).

The configuration of loader is global, only to be configured once.

import { createApp } from 'vue'
import { install as VueMonacoEditorPlugin } from '@guolao/vue-monaco-editor'

const app = createApp(App)
app.use(VueMonacoEditorPlugin, {
  paths: {
    // The default CDN config
    vs: 'https://cdn.jsdelivr.net/npm/monaco-editor@0.33.0/min/vs'
  },
})

import { loader } from "@guolao/vue-monaco-editor"

// loaded from CDN
loader.config({
  paths: {
    vs: 'https://cdn.jsdelivr.net/npm/monaco-editor@0.33.0/min/vs'
  },
})

// configurable for different languages
loader.config({ "vs/nls": { availableLanguages: { "*": "de" } } })

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

NPM Package

If you want to use monaco-editor as NPM Package to load monaco-editor files from node_modules to package into your code, you still need to use the plugin for the packaging tool.

import * as monaco from "monaco-editor"
import { loader } from "@guolao/vue-monaco-editor"

// loaded monaco-editor from `node_modules`
loader.config({ monaco })

Vite

If you use vite, you need to do this (see #1791 (comment) for details).

import { loader } from "@guolao/vue-monaco-editor"

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 })
