REST Principles

Part of the Full Stack Developer Roadmap.

Summary

An architectural style for designing APIs around resources and standard HTTP methods, with a uniform, predictable interface — the contract your frontend and backend will agree on.

How to Learn This

1Design a REST API for a resource, e.g. `/posts`, following proper conventions.
2Learn the core REST constraints: statelessness, resource-based URLs, uniform interface.
3Critique a poorly designed API you've used and identify what breaks REST conventions.
