SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill enforces runtime input validation before Prisma queries to prevent invalid data from reaching the database and to ensure type safety at the operation boundary.

Core Features & Use Cases

  • Zod Validation Pipeline: Validate external input prior to Prisma, ensuring data integrity.
  • Schema-Driven Types: Align Prisma inputs with Zod schemas to prevent mismatches.
  • Common Patterns: Example schemas for API routes, form submissions, and nested objects.

Quick Start

Define a Zod schema matching your Prisma model shape and parse incoming data before calling Prisma.

FAQPage Schema
How do I validate API request data before sending it to Prisma?▼

Validate API request inputs with Zod schemas that match your Prisma model shape, then parse the incoming data before calling Prisma operations. This ensures type safety and prevents invalid data from reaching the database.

What's the best way to enforce type-safe validation on form submissions?▼

Define a Zod schema aligned to your Prisma model, parse form submission data through that schema, and use the validated output for create or update operations. This creates a type-safe validation pipeline at the operation boundary.

Can I use Zod to validate nested objects before Prisma transactions?▼

Yes. Zod supports nested schema definitions that match complex Prisma input structures, allowing you to validate entire transaction payloads including nested relations before executing multi-step database operations.

Why validate input with Zod instead of letting Prisma handle it?▼

Zod validation catches invalid data before it reaches Prisma, preventing database errors, improving error messaging for clients, and enforcing type safety at runtime. It acts as a guard layer that protects data integrity.

Do I need to duplicate my Prisma schema when writing Zod validation schemas?▼

No. You write Zod schemas independently to match your Prisma model shape, but they serve different purposes: Zod validates external input at the boundary, while Prisma handles database constraints and transformations.
