Practical notes for turning messy API responses into safer types, validators, clients, and handoff notes.
01
JSON to TypeScript
Turn API responses into safe interfaces — optional fields, null, and arrays included.
02
JSON to Zod
Add runtime validation for when TypeScript types aren't enough and responses drift.
03
API Response to Typed Client
The full path: response → types → Zod → fetch client → mock → example.
04
Decoding JWTs Safely
Read header and payload locally, check expiry, and why signatures still matter.
05
JSON Formatter & Validator
Format, find the exact error, minify, and share JSON without leaking data.
06
Schema Quality Check
Mixed arrays, nullable IDs, big integers, unsafe names, enums, and SQL pitfalls.
07
API Contract Migration
Compare old and new responses to catch breaking changes before they ship.
08
Browser-local JSON Tools
What “your input is not uploaded” actually means, and when it matters.
