Get started - Get started with Liveblocks, Lexical, and Next.js

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

Quickstart

1. Install Liveblocks and Lexical

   Every Liveblocks package should use the same version.

   $npm install @liveblocks/client @liveblocks/react @liveblocks/react-ui @liveblocks/react-lexical lexical @lexical/react

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 react

3. Create a Liveblocks room

   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. When using Next.js’ /app router, we recommend creating your room in a Room.tsx file in the same directory as your current route.

   Set up a Liveblocks client with LiveblocksProvider, join a room with RoomProvider, and use ClientSideSuspense to add a loading spinner to your app.

   app/Room.tsx

   "use client";
   import { ReactNode } from "react";import {  LiveblocksProvider,  RoomProvider,  ClientSideSuspense,} from "@liveblocks/react/suspense";
   export function Room({ children }: { children: ReactNode }) {  return (    <LiveblocksProvider publicApiKey={"pk_prod_xxxx…xxxxxxpk_prod_xxxxxxxxxxxxxxxxxxxxxxxx"}>      <RoomProvider id="my-room">        <ClientSideSuspense fallback={<div>Loading…</div>}>          {children}        </ClientSideSuspense>      </RoomProvider>    </LiveblocksProvider>  );}

4. Add the Liveblocks room to your page

   After creating your room file, it’s time to join it. Import your room into your page.tsx file, and place your collaborative app components inside it.

   app/page.tsx

   import { Room } from "./Room";import { Editor } from "./Editor";
   export default function Page() {  return (    <Room>      <Editor/>    </Room>  );}

5. Set up the collaborative Lexical text editor

   Now that we set up Liveblocks, we can start integrating Lexical and Liveblocks in the Editor.tsx file. To make the editor collaborative, we can use LiveblocksPlugin from @liveblocks/react-lexical. FloatingToolbar adds a text selection toolbar.

   app/Editor.tsx

   "use client";
   import { LexicalComposer } from "@lexical/react/LexicalComposer";import { RichTextPlugin } from "@lexical/react/LexicalRichTextPlugin";import { ContentEditable } from "@lexical/react/LexicalContentEditable";import { LexicalErrorBoundary } from "@lexical/react/LexicalErrorBoundary";import {  liveblocksConfig,  LiveblocksPlugin,  FloatingToolbar,} from "@liveblocks/react-lexical";import { Threads } from "./Threads";
   export function Editor() {  // Wrap your Lexical config with `liveblocksConfig`  const initialConfig = liveblocksConfig({    namespace: "Demo",    onError: (error: unknown) => {      console.error(error);      throw error;    },  });
     return (    <LexicalComposer initialConfig={initialConfig}>      <div className="editor">        <RichTextPlugin          contentEditable={<ContentEditable />}          placeholder={<div className="placeholder">Start typing here…</div>}          ErrorBoundary={LexicalErrorBoundary}        />        <LiveblocksPlugin>          <Threads />          <FloatingToolbar />        </LiveblocksPlugin>      </div>    </LexicalComposer>  );}

6. Render threads and composer

   To add Comments to your text editor, we need to import a thread composer and list each thread on the page. Create a Threads.tsx file that uses FloatingComposer for creating new threads, alongside AnchoredThreads and FloatingThreads for displaying threads on desktop and mobile.

   app/Threads.tsx

   "use client";
   import { useThreads } from "@liveblocks/react/suspense";import {  AnchoredThreads,  FloatingComposer,  FloatingThreads,} from "@liveblocks/react-lexical";
   export function Threads() {  const { threads } = useThreads();
     return (    <>      <div className="anchored-threads">        <AnchoredThreads threads={threads} />      </div>      <FloatingThreads className="floating-threads" threads={threads} />      <FloatingComposer className="floating-composer" />    </>  );}

7. Style your editor

   Lexical text editor is unstyled by default, so we can create some custom styles for it in a globals.css file. Import globals.css, alongside the default Liveblocks styles. You can import them into the root layout of your app or directly into a CSS file with @import.

   app/globals.css

   app/layout.tsx

   import "@liveblocks/react-ui/styles.css";import "@liveblocks/react-lexical/styles.css";import "./globals.css";

8. 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.

   Add your users to Text Editor

9. Optional: add more features

   Lexical is a highly extensible text editor and it's possible to create complex rich-text applications. A great example is in the Lexical playground which enables features such as tables, text highlights, embedded images, and more. This is all supported using Liveblocks.
