# Novu Inbox — In-App Notification Component for React

> Integrate the Novu Inbox component for real-time in-app notifications in your application. Drop-in UI with bell icon, feed, and preferences.

Add real-time in-app notifications to your application with the Novu Inbox component. Install a client SDK such as [`@novu/react`](/platform/sdks/react), render the [`<Inbox />`](/platform/inbox/setup-inbox) component with your application identifier and subscriber ID, and Novu handles delivery, unread counts, and preferences.

The Novu Inbox is a prebuilt, ready-to-use, and fully customizable UI component for delivering real-time in-app notifications. It gives your subscribers a centralized place to view and manage notifications.

## What is the composable Inbox architecture?

The Novu Inbox is built with a composable architecture. It is composed of other sub-components:

By composing these individual components, you can create multiple popular inbox layouts that fit perfectly within your application's design.

## How does the Novu Inbox component work?

At a high level, the Inbox abstracts away the complexity of building an in-app notification feed.

1. When you drop the Inbox component into your application, it securely connects to Novu's services.
2. It automatically fetches user notifications and manages the real-time unread count displayed on the bell icon.
3. When a user clicks the bell, it presents the list of notifications and user preferences.
4. All user interactions, such as marking a notification as read or changing a preference, are automatically synchronized with the Novu backend in real-time.

## What are the ways to implement the Novu Inbox?
