Remote Config
Remote Config
Firebase Remote Config allows you to change your app’s behavior and appearance without requiring users to download an app update, enabling feature flags and A/B testing.
Installing Remote Config
bash
npm install @react-native-firebase/remote-config
Setting Default Values
javascript
import remoteConfig from '@react-native-firebase/remote-config';
await remoteConfig().setDefaults({
new_checkout_enabled: false,
welcome_message: 'Welcome to the app!',
});
Fetching and Activating Values
javascript
await remoteConfig().fetchAndActivate();
const isNewCheckoutEnabled = remoteConfig().getValue('new_checkout_enabled').asBoolean();
Using Remote Config for Feature Flags
javascript
{isNewCheckoutEnabled ?
Setting a Minimum Fetch Interval
javascript
await remoteConfig().setConfigSettings({ minimumFetchIntervalMillis: 3600000 });
Running A/B Tests
Remote Config integrates with Firebase A/B Testing, allowing you to define experiment variants and automatically measure their impact on key metrics like conversion or retention.
Common Use Cases
- Gradually rolling out new features to a percentage of users
- Toggling features on or off without an app store update
- A/B testing different UI copy or layouts
Conclusion
Firebase Remote Config provides powerful flexibility for dynamically controlling React Native app behavior and running experiments without requiring new app store submissions for every change.
