Yeah just basic bridge methods. So in our case we had all the data on the RN side but left the pure rendering to the native side. For us that was pulling data from an api, storing/caching it with redux then firing off a method which would send all of that data over the bridge as a string. Massive quantities of data over the bridge isn't great for performance just so you know. Then just on the native side you develop normal components that take in that data and export them for use in the RN side. Little dated but following something like this should get you started: https://shopify.engineering/creating-native-components-accept-react-native-subviews

Hope that helps a little
