REST — Comprehensive Revision Sheet

maang.io System Design Series

What is this?

This is your night-before-the-interview page — the whole REST chapter compressed to what fits on one mental index card. Think of it as the library's quick-reference desk: you already know how the place works, you just need the call numbers fast.

The one-line idea: REST = resources with stable URLs, acted on by a uniform set of HTTP verbs, served statelessly so it scales. Everything below hangs off that sentence.

If a line here surprises you, that's your signal to reread the relevant Part.
