Flipper gRPC plugin

This is a plugin for Facebook debugging tool Flipper for logging gRPC requests from mobile clients.

Desktop

You need to install desktop version of the plugin to the Flipper desktop app. Open View > Manage Plugins > Install plugins and search for grpc. Once installed restart the desktop app.

Android

Gradle

dependencies {
    ...
    implementation "cz.ackee.flipper:grpc:x.x.x"
}

App

Inside your Flipper init phase add FlipperGrpcPlugin and keep the instance somewhere to be used later

class App : Application() {

    companion object {
        val flipperGrpcPlugin = FlipperGrpcPlugin()
    }

    override fun onCreate() {
        super.onCreate()
        SoLoader.init(this, false)

        val client = AndroidFlipperClient.getInstance(this)
        ...
        client.addPlugin(flipperGrpcPlugin)
        ...
    }
}

When creating your gRPC channel add ClientInterceptor provided by the plugin

val channel = OkHttpChannelBuilder
     ...
     .intercept(App.flipperGrpcPlugin.getInterceptor())
     .build()

and that's it. If you run your app you should now see requests in Flipper

Sample app

If you want to run Android sample app you need either to provide your own proto files and definition of host/port or you can use the demo helloworld app taken from grpc-java (repository)[https://github.com/grpc/grpc-java/tree/master/examples].

You need to build the hello-world-server app and run it on your localhost and then use emulator to run the sample app.

iOS

Currently gRPC Swift does not have a concept of interceptors and without them it's hard to provide a library that could be easily plugged in your code. We are watching closely this issue in the repository and once possible we will hop on that!
