    "Learn how to install a SuperDoc DOCX editor using Liveblocks and JavaScript"
---

Liveblocks is a realtime collaboration infrastructure for building performant
collaborative experiences. Follow the following steps to start adding
collaboration to your JavaScript application using the APIs from the
[`@liveblocks/yjs`](/docs/api-reference/liveblocks-yjs) package, and
[SuperDoc](https://superdoc.dev), a collaborative DOCX editor for the web.

## Quickstart

<PromptCta />

<Steps>
  <Step>
    <StepTitle>Install Liveblocks, Yjs, and SuperDoc</StepTitle>
    <StepContent>

      Every Liveblocks package should use the same version.

      ```bash trackEvent="install_liveblocks"
      npm install @liveblocks/client @liveblocks/yjs yjs superdoc
      ```
    </StepContent>

  </Step>

  <Step>
    <StepTitle>Initialize the `liveblocks.config.ts` file</StepTitle>
    <StepContent>

      We can use this file later to [define types for our application](/docs/api-reference/liveblocks-client#Typing-your-data).

      ```bash
      npx create-liveblocks-app@latest --init --framework javascript
      ```

    </StepContent>

  </Step>

  <Step>
    <StepTitle>Create the HTML elements</StepTitle>
    <StepContent>

      ```html
      <div id="superdoc-toolbar"></div>
      <div id="superdoc" style="height: 700px"></div>
      ```

    </StepContent>

  </Step>

  <Step>
    <StepTitle>Set up your collaborative SuperDoc editor</StepTitle>
    <StepContent>

      SuperDoc relies on browser APIs, so we wait for the provider’s first `sync`
      before mounting the editor, and pass the shared `ydoc` and `provider` to
      SuperDoc through `modules.collaboration`.

      ```js file="app.js"
      import { createClient } from "@liveblocks/client";
      import { getYjsProviderForRoom } from "@liveblocks/yjs";
      import { SuperDoc } from "superdoc";
      import "superdoc/style.css";

      // Set up Liveblocks client
      const client = createClient({
        publicApiKey: "{{PUBLIC_KEY}}",
      });

      // Enter a multiplayer room
      const { room, leave } = client.enterRoom("my-room");

      // Set up Yjs document and Liveblocks Yjs provider
      const yProvider = getYjsProviderForRoom(room);
      const yDoc = yProvider.getYDoc();

      function initSuperDoc() {
        // Get the current user's info from Liveblocks
        const { id, info } = room.getSelf();

        new SuperDoc({
          selector: "#superdoc",
          toolbar: "#superdoc-toolbar",
          documentMode: "editing",
          user: {
            email: id,
            name: info?.name ?? "Anonymous",
            image: info?.avatar ?? undefined,
          },
          modules: {
            // The collaboration contract is the same for every Yjs provider:
            // pass the shared `ydoc` and `provider`
            collaboration: { ydoc: yDoc, provider: yProvider },
          },
        });
      }

      // Wait for the initial sync so the document isn’t created twice
      if (yProvider.synced) {
        initSuperDoc();
      } else {
        yProvider.on("sync", initSuperDoc);
      }
      ```
    </StepContent>

  </Step>

  <Step lastStep>
    <StepTitle>Next: set up authentication</StepTitle>
    <StepContent>
      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.

        <a href="/docs/authentication">
          Set up authentication
        </a>
      </Button>
    </StepContent>

  </Step>
</Steps>
