type-safety-validation

What problem does it solve?

End-to-end type safety ensures bugs are caught at compile time, not runtime. This skill covers Zod for runtime validation, tRPC for type-safe APIs, Prisma for type-safe database access, and modern TypeScript features.

Core Features & Use Cases

• Zod validation: Use robust runtime validation to ensure inputs conform to schemas.
• Type-safe APIs: Build APIs with tRPC that infer types from server to client.
• Type-safe ORM: Use Prisma to enforce typed database access and migrations.
• End-to-end typing: Apply TS 5.7+ features to improve safety and developer ergonomics.
• Use Case: Create a full-stack app where the database schema, API, and client all share the same TypeScript types.
• Use Case: Migrate a JS project to TS with strict runtime validation and typed APIs.

Quick Start

Install the necessary packages (zod, @trpc/server, @trpc/client, prisma, etc.), scaffold a minimal TypeScript project, and implement a simple getUser API with input validation.
