React Advanced 2023

Today's Talk introduces Flashlight, a tool for measuring mobile app performance. Flashlight provides a performance report that highlights issues like high CPU usage on low-end devices. To fix these issues, the Shopify component Flashlist can be used. Flashlight can also be used locally to measure performance changes in React Native apps, with the ability to see the score rapidly changing and improved performance after implementing fixes. More information can be found in the documentation and an article comparing scrolling performance in React Native.

The promise of Lighthouse is pretty cool, right? Visit any website, and with only a few clicks, you can get a performance score for it!Wouldn’t it be grand if we had the same thing for React Native apps?  Well, you’re in luck! let me present our new open source tool called Flashlight 🔦 (cause you know, a Flashlight is basically a very small “mobile” lighthouse, right?)
