Building custom notifications UI with hooks (headless)
Using our @knocklabs/react-native library, you can create fully custom notification UIs that are backed by the Knock Feed API and real-time service.
In this guide, you'll find common recipes to help you build in-app feed experiences within your React Native applications in a headless way using the Knock hooks. The SDK handles all aspects of managing the data surrounding notifications on your behalf, including managing unread badge counts.

Getting started
To use this example, you'll need an account on Knock, as well as an in-app feed channel with a workflow that produces in-app feed messages. You'll also need:
- A public API key for the Knock environment (set as
KNOCK_PUBLIC_API_KEY) - The channel ID for the in-app feed (set as
KNOCK_FEED_CHANNEL_ID)
Installing dependencies
When using React Native with Expo, install our Expo SDK instead:

Filtering/scoping a feed
A feed can be scoped by any of the parameters that are accepted on the feed endpoint via the FeedClientOptions set in the defaultFeedOptions for the KnockFeedProvider component, or via the useNotifications hook.
You can read more in this guide on feed filtering.
