# Next.js In-App Notifications Quickstart — Novu Inbox

  # Add Novu Inbox to Next.js App

  Install `@novu/nextjs`. Add the `<Inbox />` component to your header, navbar, or sidebar.

  Latest docs: [https://docs.novu.co/platform/quickstart/nextjs](https://docs.novu.co/platform/quickstart/nextjs)

  ## Install

  ```bash theme={null}
  npm install @novu/nextjs
  ```

  ## Component

  ```tsx theme={null}
  'use client';
  import { Inbox } from '@novu/nextjs';

  export default function NotificationInbox() {
    return (
      <Inbox
        applicationIdentifier="YOUR_APPLICATION_IDENTIFIER"
        subscriberId="YOUR_SUBSCRIBER_ID"
      />
    );
  }
  ```

  ## Subscriber ID

  Use the app's existing auth system to get a unique user identifier for subscriberId. Check for Clerk, NextAuth, Firebase, Supabase, or custom auth. If no auth system exists, use `YOUR_SUBSCRIBER_ID`.

  ## Appearance

  Extract design tokens from the host app (Tailwind config, CSS variables, theme objects) and apply them via the appearance prop. Only include values you extracted from the host design system — omit empty or placeholder appearance values.

  ## Rules

  ALWAYS:

  * Detect the project's package manager and use it for installation
  * Extract design tokens and apply via the appearance prop
  * Place `<Inbox />` inline in existing UI — no new pages or wrappers
  * Use TypeScript, no comments, no empty props
  * Follow Next.js conventions
  * Use the existing auth system to source subscriberId when available

  NEVER:

  * Add empty appearance values or placeholder props
  * Create wrapper components or new pages just for the inbox
  * Add code comments
  * Introduce styles not in the host app
  * Add unused props or imports

  ## Verify Before Responding

  1. Is `@novu/nextjs` installed with the project's package manager?
  2. Is `<Inbox />` placed inline in existing UI?
  3. Are design tokens extracted and applied?
  4. Are all props non-empty and properly typed?
  5. Is subscriberId sourced from the auth system when available?

  If any fails, revise.

<Steps>
  <Step>
    ### Create a Novu account

    [Create a Novu account](https://dashboard.novu.co/auth/sign-up) or [sign in](https://dashboard.novu.co/auth/sign-in) to access the Novu dashboard.
  </Step>

  <Step>
    ### Create a new Next.js application

    Run the following command to [create a new Next.js application](https://nextjs.org/docs/app/getting-started/installation):

    ```package-install theme={null}
    npm create next-app@latest
    ```
  </Step>

  <Step>
    ### Install `@novu/nextjs`

    Run the following command to install the Next.js Novu SDK:

    ```package-install theme={null}
    npm install @novu/nextjs
    ```
  </Step>

  <Step>
    ### Add the notification Inbox to your app

    Import Novu’s built-in [`<Inbox />`](/platform/inbox) component into your layout file and place it in the navbar:

    ```tsx app/layout.tsx theme={null}
    'use client';

    import { Inbox } from '@novu/react';

    export function NovuInbox() {
      return (
        <Inbox
          applicationIdentifier="YOUR_APPLICATION_IDENTIFIER"
          subscriberId="YOUR_SUBSCRIBER_ID"
        />
      );
    }
    ```

    If you are signed in to your Novu account, then the <Tooltip tip="The application identifier is a unique identifier for your application.">applicationIdentifier</Tooltip> and <Tooltip tip="The subscriber ID is the unique identifier for the user in your application, typically the user's ID in your database.">subscriberId</Tooltip> will be automatically populated. Otherwise, retrieve them from:

    * `applicationIdentifier`: On the Novu dashboard, click **API Keys**, and copy your unique Application Identifier.
    * `subscriberId`: This represents a user in your system, usually the user ID from your database. For testing, you can use the auto-generated subscriberId from your Novu dashboard. You can locate it under the Subscribers tab on the Novu dashboard.

    <Note>
      If you pass a `subscriberId` that does not exist yet, Novu will automatically create a new subscriber with that ID.
    </Note>
  </Step>

  <Step>
    ### Run your application

    Start your development server:

    ```package-install theme={null}
    npm run dev
    ```

    Once your application is running, you would see a **bell icon** in the navbar. Click on it, to open the notification Inbox UI.

    There are no notifications yet, so let’s trigger one!
  </Step>

  <Step>
    ### Trigger your first notification

    In this step, you'll create a simple workflow to send your first notification via the Inbox component. Follow these steps to set up and trigger a workflow from your Novu dashboard.

    1. Go to your [Novu dashboard](https://dashboard.novu.co/auth/sign-in).
    2. Click **Workflows**.
    3. Click **Create Workflow** and then enter a name (e.g., "Welcome Notification").
    4. Click **Create Workflow** to save it.
    5. Click the **Add Step** icon in the workflow editor and then select **In-App** as the step type.
    6. In the **In-App template editor**, enter:
       * **Subject**: "Welcome to Novu"
       * **Body**: "Hello, world!"
    7. Once you’ve added the subject and body, close the editor.
    8. Click **Trigger**.
    9. Click **Test Workflow**.
  </Step>

  <Step>
    ### View the notification in your app

    Go back to your Next.js app, then click the bell icon.

    You should see the notification you just sent from Novu! 🎉
