Case Study: Real-Time JSON to Zod Schema Compiler

JZod is a developer productivity tool engineered to eliminate the manual, error-prone task of translating raw JSON API responses into validated TypeScript/Zod schemas.

Technical Architecture

• Recursive AST Parsing: Built an in-memory parser in TypeScript that inspects nested objects, detects nullable types, infers primitive unions, and outputs formatted, idiomatic Zod schemas.
• Two-Way Transformation: Capable of compiling JSON → Zod schema trees as well as generating mock JSON mock fixtures from existing Zod schemas.
• 100% Client-Side Privacy: Zero server telemetry ensures developers can safely paste proprietary data structures without risk of external data leakage.
