If you’re unfamiliar with React Native, it is a development framework which allows developers to write code just once to build native apps for Android and iOS. Our latest State of React Native report examines global trends for apps built in React Native so be sure to check it out if you're interested in learning more about this framework.
It boasts some impressive metrics, for example time to interaction (TTI), a measure of how quickly an app starts, is more than halved in some real world applications.
You can learn more about how Hermes is implemented in Facebook Engineering’s blog.
Bugsnag fully supports Hermes in Bugsnag React Native v2.22.6 and above. To get started, you’ll need to enable Hermes in your React Native app. Then just upload your source maps to Bugsnag following the instructions for Hermes here.
As with any major new component, it’s inevitable that Hermes will have some bugs. That’s why it’s essential to monitor your app’s stability score to gain confidence when rolling it out.
Bugsnag’s stability management platform monitors application stability and uses real-time error rates and session data to provide stability scores for each release. Automatically captured error reports surface detailed diagnostic data such as device model, OS version, thread state, breadcrumbs, and much more to help you easily reproduce and fix errors.
Companies like Zynga, Shopify and J.B. Hunt use Bugsnag for their React Native apps.
