Building microservices with Kotlin and gRPC

on YouTube ↗41m

" summary

Shows a working Kotlin microservice stack using gRPC and Protocol Buffers: an HTTP/2, binary API with bi-directional streaming implemented as a Death Star demo that destroys and regenerates planets. Code uses Kotlin coroutines and channels to replace Java stream observers and callback hell, adds interceptors to mutate requests and map business errors to gRPC statuses, and runs tests with in-process Server/Channel for unit and integration checks. Demo proves it runs and scores updates reflect the interceptors.
