GO Feature Flag: Now Powering Your Mobile App Experience

Why Mobile Feature Flags Matter?​

Mobile app development is a fast-paced world where agility is key. Traditional release cycles can be lengthy and risky. Feature flags provide a dynamic solution by allowing you to control feature visibility without redeploying your app.

This translates to:

  • Faster time-to-market: Experiment with new features and iterate quickly based on user feedback.
  • Reduced risk: Gradually roll out features to minimize potential issues and impact.
  • Enhanced control: Turn features on or off in real-time based on user segments or other criteria.

How GO Feature Flag Delivers for Mobile​

To bring feature flags to mobile, we've fully embraced the OpenFeature standard.

This means:

  • Native support for iOS and Android: A provider for each platform ensures seamless integration with the OpenFeature SDKs in your mobile app's core.
  • React Native compatibility: With the usage of GO Feature Flag web provider and the OpenFeature React SDK you can now manage feature flags within your React Native app using familiar JavaScript syntax.

Diving Deeper into the Tech​

When it comes to client side, on the 3 platforms we are using the OpenFeature static paradigm (client side SDK). What does it means? The key distinction between the client- and server-side feature flagging is the difference in how often evaluation context changes.

When on your mobile device, your evaluation context is changing very rarely since the device is linked to a user. Also, in the client, you expect a very low latency to get the value of your flag. Based on this idea, the GO Feature Flag providers will retrieve your set of flags and cache them on the device, so you can evaluate them without any network call.

For those interested in the technical details, let's explore how this integration works in this sequence diagram:

As you can see, the provider is keeping all the flags in memory to serve them as fast as possible without any network call.
