Input Validation
Input validation ensures that data entering the system is correct, safe, and expected. It is the first line of defense against injection, corruption, and malformed requests.
The resources below cover schema validation, sanitization, custom validators, and error messages. Each recipe shows how to validate input at boundaries without leaking internal details.
Every resource includes clear explanations, copy-paste code, and practical warnings. Use them to make informed decisions, avoid production pitfalls, and speed up your delivery. If you are just getting started, read the beginner-friendly articles first; if you are experienced, jump straight to the advanced patterns and architecture guides. New resources are added regularly, so bookmark this page and check back for the latest patterns.
