sdk
npm install bkt-react-native-client-sdkThis SDK enables seamless access to your feature flags in React Native applications using Bucketeer. It provides React hooks and components for easy integration, and is built on top of the robust @bucketeer/react-client-sdk and @bucketeer/js-client-sdk.
Bucketeer is an open-source platform created by CyberAgent to help teams make better decisions, reduce deployment lead time and release risk through feature flags. Bucketeer offers advanced features like dark launches and staged rollouts that perform limited releases based on user attributes, devices, and other segments.
> [!WARNING]
> This is a beta version. Breaking changes may be introduced before general release.
For documentation related to flags management in Bucketeer, refer to the Bucketeer documentation website.
- Most APIs and usage are identical to the React SDK.
- The main difference: make sure use defineBKTConfigForReactNative to build your configuration.
``sh`
npm install @bucketeer/react-native-client-sdk
This SDK uses @react-native-async-storage/async-storage for bootstrapping, which is a native dependency. If you don't have it installed, the evaluation will not be cached between app restarts.
For Expo projects:
Adding the Bucketeer React Native SDK from npm and re-running pod install should suffice.@react-native-async-storage/async-storage
If it doesn't work, you may need to install as a dependency in your project.
`sh`
npx expo install @react-native-async-storage/async-storage
For bare React Native projects:
You'll need to explicitly add as a dependency to your project and re-run pod install for auto-linking to work. This is because auto-linking does not work with transitive dependencies.
`sh`
npm install @react-native-async-storage/async-storage
cd ios && pod install # For iOS
For more details, see: https://react-native-async-storage.github.io/async-storage/docs/install/
Initialize the Bucketeer client and provide it to your app using the BucketeerProvider:
> Use defineBKTConfigForReactNative to create your config and defineBKTUser to create a user and initializing the client using initializeBKTClient
`tsx
import React, { useEffect, useState } from 'react';
import {
BucketeerProvider,
defineBKTConfigForReactNative,
initializeBKTClient,
getBKTClient,
defineBKTUser,
type BKTClient,
} from '@bucketeer/react-native-client-sdk';
const config = defineBKTConfigForReactNative({
apiKey: 'your-api-key',
apiEndpoint: 'https://api.bucketeer.io',
appVersion: '1.0.0',
featureTag: 'mobile',
});
const user = defineBKTUser({
id: 'user-123',
customAttributes: {
platform: 'react-native',
version: '1.0.0',
},
});
export default function App() {
const [client, setClient] = useState
useEffect(() => {
const init = async () => {
try {
await initializeBKTClient(config, user);
const bktClient = getBKTClient();
setClient(bktClient);
} catch (error) {
if (error instanceof Error && error.name === 'TimeoutException') {
// TimeoutException but The BKTClient SDK has been initialized
console.warn(
'Bucketeer client initialization timed out, but client is already initialized.'
);
} else {
console.error('Failed to initialize Bucketeer client:', error);
return; // Exit early for non-timeout errors
}
}
};
init();
// Cleanup client on unmount or when necessary
return () => {
destroyBKTClient();
};
}, []);
if (!client) {
return
return (
);
}
`
> If you see a TimeoutException` error during initialization, it means the Bucketeer client has already been initialized successfully. This error is safe to ignore and does not affect the client’s functionality.
This SDK re-exports all APIs from the React SDK.
