Which package should I use for the useFlags hook?

While initialization is handled by @featbit/react-native-sdk, consumption hooks like useFlags must be imported from @featbit/react-client-sdk.

Can I use this skill with Expo projects?

Yes, this skill provides specific guidance for both React Native CLI and Expo applications, including client-side flag evaluation.

Does it support real-time feature flag updates on mobile?

Yes, the SDK connects via WebSocket to sync flag data for the current user and performs evaluations locally on the device.

How does the React Native SDK differ from the React web SDK?

The React Native SDK requires a mandatory buildConfig() call before the provider and uses different user object keys: keyId and name, instead of id and userName.

Mobile Development

Streamlines the integration of FeatBit feature flags into React Native and Expo mobile applications with expert configuration guidance.

This skill provides specialized instructions for implementing the FeatBit React Native SDK in mobile development environments, covering both React Native CLI and Expo. It guides developers through the unique setup requirements of the mobile SDK, such as the mandatory buildConfig normalization, while managing the distinction between initialization and hook consumption. By automating the boilerplate and ensuring correct property naming conventions like keyId, it helps teams implement robust feature flag management and user targeting directly on mobile devices with real-time WebSocket synchronization.
