This course teaches you to build blazing-fast, schema-first APIs using Protocol Buffers (Protobuf) and gRPC. You’ll begin by writing .proto files to define your API contracts and then use the official Go plugin (protoc-gen-go) to generate type-safe client and server stubs.
You’ll implement:
-
Unary RPCs: standard request/response methods.
-
Server streaming: stream large results back to the client efficiently.
-
Client streaming: send multiple requests and get a single response.
-
Bidirectional streaming: build real-time chat or live telemetry systems.
You’ll also add TLS encryption, interceptors for authentication, and context deadlines for timeouts and cancellations. On the client side, you’ll use Go’s generated stubs to build robust consumers with retries and backoff strategies.
Finally, you’ll learn how to expose your gRPC services to non-gRPC clients by adding a gRPC-Gateway that automatically translates gRPC calls into REST/JSON. By the end, you’ll be able to build production-grade, high-performance services in Go that outperform traditional REST APIs.
