Code Generation and Stubs

The magic that makes an RPC feel like a local function call is code generation. You run a compiler over your `.proto` file and out come typed classes and methods for your language — the client stub you call and the server interface you implement. Understanding what's generated, and the boundary between generated and hand-written code, is what turns gRPC from a black box into a tool you control.

Protocol Buffers: The Contract and the Wire Format

Protocol Buffers are the foundation gRPC is built on — both the language you write your API contract in and the binary format your data travels as. A `.proto` file is a strict, versioned schema; the encoding is a compact, tag-based binary that's a fraction of JSON's size. Understanding both halves — the schema language and how it serializes — is what lets you design APIs that stay compatible as they evolve.

Why RPC, and Why gRPC

REST won the public web, but inside a system — between the dozens of services that make up a modern backend — a different model dominates: RPC. Instead of modeling everything as resources and verbs over HTTP, you call a remote function as if it were local. gRPC is the modern, high-performance realization of that idea, built on Protocol Buffers and HTTP/2. Understanding why it exists explains when to reach for it over REST.
