The New React Native: Bringing the Fabric renderer to the “Facebook” app


From 2018 until mid-2021, the React Native core team at Facebook migrated the Facebook app to use the new Fabric renderer. I will be talking about the journey of shipping the new Fabric renderer fully in the Facebook app; challenges we faced along the way; and how we overcame them. This talk will be less about Fabric itself (the “what”) and more about our experiences of using it at scale and migrating a very large codebase to using exclusively Fabric (the “how”), and what we learned along the way.
