Notes from React Native EU

Turbo Modules

  • The current native modules (aka bridge modules) architecture has some flaws:
    • There is no way to defer its initalization to the future since the native modules registry needs to compute methods of all native modules at runtime.
    • Inbuilt (inside react native core) or custom (written by user) native modules cannot be stripped from final build if unused
    • Currently, synchronously calling native module methods is possible but is not really recommended because Chrome Debugger does not support it
  • Turbo modules (react-native-community/discussions-and-proposals#11) solves most of these problems:
    • There is an idea in the proposal to generate Obj C/Java classes using native module shape defined with flow types (or potentially any type system, like typescript) at build time. This removes the initialization step completely since the native code already knows the shape of the native module.
  • As such, native modules that are not used in user land code wi
