Performance Does Matter - Making Your React-Native App Fast Again


Ever wondered if your Product Manager is the only pushing for new features without any limits, while you are trying to keep app performance at it’s best? Well, don’t you worry, you’re not alone! Come and learn how to improve your React Native app performance with few simple tricks. In the past 5 years, the Wix mobile app has gone through quite a bit - a brand new look was launched, a large number of features were added in a short period of time, and the number of our users tripled. Unfortunately, one implication of product growth, is a slower performance, especially when it came to things like seamless transition, fluent animations and general slickness of the app. Over the past year, we made a tremendous effort to improve these regressions. Our ongoing efforts have so far resulted in almost 60% cumulative improvement in all performance metrics. In this talk, I’ll deep into all of our secret ingredients for better performance in React Native applications, together with practical examples of: -Improving startup time -Responsive gestures -Preload prioritization Furthermore, I’ll outline some general work we’ve done that led us to these improvements, like the right way to measure and analyse your app performance on production, and how you can implement these tips and tricks.
