Get started with a SuperDoc DOCX editor using Liveblocks and React

Liveblocks is a realtime collaboration infrastructure for building performant collaborative experiences. Follow the following steps to start adding collaboration to your React application using the APIs from the @liveblocks/yjs package, and SuperDoc, a collaborative DOCX editor for the web.

Quickstart

Install Liveblocks, Yjs, and SuperDoc
Every Liveblocks package should use the same version.
Terminal
npm install @liveblocks/client @liveblocks/react @liveblocks/yjs yjs @superdoc-dev/react
Initialize the liveblocks.config.ts file
We can use this file later to define types for our application.
Terminal
npx create-liveblocks-app@latest --init --framework react

Set up the Liveblocks client

Liveblocks uses the concept of rooms, separate virtual spaces where people collaborate, and to create a realtime experience, multiple users must be connected to the same room. Set up a Liveblocks client with LiveblocksProvider, and join a room with RoomProvider.

App.tsx

"use client";
import {  LiveblocksProvider,  RoomProvider,} from "@liveblocks/react/suspense";import { Editor } from "./Editor";
export default function App() {  return (    <LiveblocksProvider publicApiKey={""}>      <RoomProvider id="my-room">        {/* ... */}      </RoomProvider>    </LiveblocksProvider>  );}

Join a Liveblocks room

After setting up the room, you can add collaborative components inside it, using ClientSideSuspense to add loading spinners to your app.

App.tsx

"use client";
import {  LiveblocksProvider,  RoomProvider,  ClientSideSuspense,} from "@liveblocks/react/suspense";import { Editor } from "./Editor";
export default function App() {  return (    <LiveblocksProvider publicApiKey={""}>      <RoomProvider id="my-room">        <ClientSideSuspense fallback={<div>Loading…</div>}>          <Editor />        </ClientSideSuspense>      </RoomProvider>    </LiveblocksProvider>  );}

Set up the collaborative SuperDoc editor

Now that we set up Liveblocks, we can start integrating SuperDoc and Yjs in the Editor.tsx file. We use getYjsProviderForRoom to get a Yjs document and provider, then pass them to the <SuperDocEditor /> component through modules.collaboration. The component handles mounting, cleanup, and SSR for you. It rebuilds when modules changes, so we memoize it.

Editor.tsx

"use client";
import { useMemo } from "react";import { getYjsProviderForRoom } from "@liveblocks/yjs";import { useRoom, useSelf } from "@liveblocks/react/suspense";import { SuperDocEditor } from "@superdoc-dev/react";import "@superdoc-dev/react/style.css";
// Collaborative DOCX editor with live cursors, powered by SuperDocexport function Editor() {  const room = useRoom();  const yProvider = getYjsProviderForRoom(room);
  // Get the current user's info from Liveblocks  const userInfo = useSelf((me) => me.info);  const userId = useSelf((me) => me.id);
  const modules = useMemo(    () => ({      // The collaboration contract is the same for every Yjs provider:      // pass the shared `ydoc` and `provider`      collaboration: { ydoc: yProvider.getYDoc(), provider: yProvider },    }),    [yProvider]  );
  return (    <div style={{ height: "100vh" }}>      <SuperDocEditor        documentMode="editing"        // Identify the current user for live cursors        user={{          email: userId,          name: userInfo?.name ?? "Anonymous",          image: userInfo?.avatar ?? undefined,        }}        modules={modules}        style={{ height: "100%" }}      />    </div>  );}

Next: authenticate and add your users
Text Editor is set up and working now, but each user is anonymous—the next step is to authenticate each user as they connect, and attach their name, color, and avatar, to their cursors and mentions.
