Beyond REST in API

Lessons in this section

1. GraphQL

   Let the client ask for exactly the fields it needs, in one request, with a GraphQL query.

2. gRPC

   Let services talk fast with small binary protobuf messages and a strict .proto contract.

3. REST vs GraphQL vs gRPC

   Start with REST, and pick GraphQL, gRPC, webhooks or Server-Sent Events only when you have a clear reason.

4. Capstone Project: Loyalty Points API

   Build a complete Loyalty Points API for Brew & Bytes: validated, retry-safe, authorized, versioned, documented and monitored.
