Protocol buffer

As explained in Go in Practice, Second Edition

Protocol Buffers is a language- and platform-neutral schema system and compact binary serialization format for structured data, with support for generated code.

How Go in Practice, Second Edition covers it

How deep it goes

Explains schemas, generated bindings, commands, servers, clients, and trade-offs, but does not detail binary encoding internals.

Examples

Uses a proto3 chat schema, protoc generation, a Python gRPC server, and a Go client calling RouteComments.

What you can do after

Build cross-language gRPC messages and services, generate bindings, run a server, and invoke it from a client.

How it connects

Connects protobuf with gRPC, RPC, REST, JSON, serialization, code generation, and backward-compatible API contracts.
