We just released a revised version of the guide from 2020.

Added 5 new chapters and 80+ pages. So now all it takes to write performant RN apps is just going through 200+ pages of tips, tricks, tools and tactics :D

Jokes aside. Optimizing mobile app perf without regressions is no easy task. It's no different with React Native. Some say it's less performant by default, some say the opposite. At Callstack we've helped dozens of teams optimize their React Native apps and as a result we came up with this free guide for anyone to grab.

Hope you'll like it! I was involved in creating this ebook and I'm happy to answer any questions you may have :)
