Get started - Get started with Liveblocks, CodeMirror, Yjs, and Vue.js

Liveblocks is a real-time collaboration infrastructure for building performant collaborative experiences. Follow the following steps to start adding collaboration to your Vue.js application using the APIs from the @liveblocks/yjs package.

Quickstart

  1. Install Liveblocks, Yjs, and CodeMirror

    $npm install @liveblocks/client @liveblocks/yjs yjs codemirror @codemirror/lang-javascript y-codemirror.next

  2. Set up your collaborative CodeMirror code editor

    Editor.vue
    <script setup>import { ref, onMounted, onUnmounted } from "vue";import { createClient } from "@liveblocks/client";import LiveblocksProvider from "@liveblocks/yjs";import * as Y from "yjs";import { yCollab } from "y-codemirror.next";import { EditorView, basicSetup } from "codemirror";import { EditorState } from "@codemirror/state";import { javascript } from "@codemirror/lang-javascript";
    const roomId = "my-room";const parent = ref(null);const view = ref(null);
    // Set up Liveblocks clientconst client = createClient({  publicApiKey: "pk_prod_xxxxxxxxxxxxxxxxxxxxxxxx",});
    // Enter a multiplayer roomconst room = client.enter(roomId, {  initialPresence: {},});
    // Set up Yjs document, shared text, and Liveblocks Yjs providerconst yDoc = new Y.Doc();const yText = yDoc.getText("codemirror");const yProvider = new LiveblocksProvider(room, yDoc);
    onMounted(() => {  // Set up CodeMirror and extensions  const state = EditorState.create({    doc: yText.toString(),    extensions: [      basicSetup,      javascript(),      yCollab(ytext, yProvider.awareness, { undoManager }),    ],  });
      // Attach CodeMirror to element  view.current = new EditorView({    state,    parent: parent.value,  });});
    onUnmounted(() => {  view?.destroy();  client.leave(roomId);});</script>
    <template>  <div ref="parent" /></template>

  3. Next: set up authentication

    By default, Liveblocks is configured to work without an authentication endpoint where everyone automatically has access to rooms. This approach is great for prototyping and marketing pages where setting up your own security isn’t always required. If you want to limit access to a room for certain users, you’ll need to set up an authentication endpoint to enable permissions.
