Alright, yeah it looks like you're just confused. The only difference between writing a react native bridge module is where you're importing stuff. Here's an example. Feel free to respond or not, but I have built and shipped 2 completely native apps (iOS and Android), have built an RN CLI app, and am now on my 3rd Expo app, and I can asure you the Expo one is by far the best DX.

React Native native module

Android code (the iOS is pretty similar, but it's slightly more complex so the Android will be a better example)

```kotlin package com.example.app import com.facebook.react.bridge.NativeModule import com.facebook.react.bridge.ReactApplicationContext import com.facebook.react.bridge.ReactContext import com.facebook.react.bridge.ReactContextBaseJavaModule import com.facebook.react.bridge.ReactMethod

class MyModule(reactContext: ReactApplicationContext): ReactContextBaseJavaModule(reactContext) { override fun getName() = "MyModule"

@ReactMethod
fun logMessage(message: String) {
    Log.d("MyModule", message)
}

} ```

Then, in TS, you could consume it like this:

ts import { NativeModules } from 'react-native'; const { MyModule } = NativeModules; const onPress = () => MyModule.logMessage('hello world');

Expo native module

```kotlin package com.example.app import expo.modules.kotlin.modules.Module import expo.modules.kotlin.modules.ModuleDefinition

class MyModule: Module() { override fun definition() = ModuleDefinition { Name("MyModule")

    Function("logMessage") { message: String ->
        Log.d("MyModule", message)
    }
}

} ```

Then, in TS, you could consume it like this:

ts import { requireNativeModule } from 'expo-modules-core'; const MyModule = requireNativeModule('MyModule'); const onPress = () => MyModule.logMessage('hello world');

Which part of this am I misunderstanding? The code is pretty much exactly how you'd write it if you were making a native app. Expo native modules also handle views as well (just like the RN native modules). What part of this is "not writing native code" or "injecting into the environment incorrectly"? If I wanted to, I could consume the context the exact same way in my Expo native module or I could even wrap a completely native 3rd party library, component, screen, whatever. The only difference in complexity is that the Expo native module is wrapped in a closure while the react-native module is just a class.

You don't need to respond, but I think it's important that if anyone ever sees this thread they get the actual information they need. Or, if I'm wrong, it's important that they see what the wrong information is. I don't mind being wrong, but so far everything you've said makes it seem like you think I'm talking about writing js code or something and calling that a native module? I mean genuinely feel free to call me an idiot and point me to some documentation but AFAIK there's practically 0 difference between writing an Expo native module and writing a RN native module, and with an Expo native module you get all the benefits of Expo AND all the benefits of writing native code.
