Get startedGet started with Liveblocks, Monaco, Yjs, and Svelte

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


  1. Install Liveblocks, Yjs, and Monaco

    Every Liveblocks package should use the same version.

    $npm install @liveblocks/client @liveblocks/yjs yjs monaco-editor y-monaco
  2. Initialize the liveblocks.config.ts file

    We can use this file later to define types for our application.

    $npx create-liveblocks-app@latest --init --framework javascript
  3. Set up your collaborative Monaco code editor

    <script>import { onMount, onDestroy } from "svelte";import { createClient } from "@liveblocks/client";import { LiveblocksYjsProvider } from "@liveblocks/yjs";import * as Y from "yjs";import * as monaco from "monaco-editor";import { MonacoBinding } from "y-monaco";
    let element;const roomId = "my-room";
    // Set up Liveblocks clientconst client = createClient({ publicApiKey: "",});
    onMount(() => { // Enter a multiplayer room const { room, leave } = client.enterRoom(roomId);
    // Set up Yjs document, shared text, and Liveblocks Yjs provider const yDoc = new Y.Doc(); const yText = yDoc.getText("monaco"); const yProvider = new LiveblocksProvider(room, yDoc);
    // Set up the Monaco editor const editor = monaco.editor.create(element, { value: "", language: "javascript" })
    // Attach Yjs to Monaco const binding = new MonacoBinding( yText, editorRef.getModel(), new Set([editor]), yProvider.awareness );
    return () => { binding.destroy(); editor.dispose(); leave(); };});
    <div bind:this={element}></div>
  4. 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.
