APIs

Part of the Full Stack Developer Roadmap.

Summary

The contract that lets your frontend and backend (or any two systems) talk to each other — defining what requests are possible and what data comes back. Designing and consuming APIs well is the connective tissue of full-stack work.

How to Learn This

1Design a simple API contract (endpoints, request/response shapes) before writing any code for a feature.
2Consume a public API from a small frontend to practice the client side of this contract.
3Learn why a well-documented API lets frontend and backend work happen in parallel, not sequentially.
