validated-handler

What problem does it solve?

This Skill eliminates repetitive boilerplate code for validating API request inputs in Next.js, ensuring type safety and consistent error handling.

Core Features & Use Cases

• Automatic Input Validation: Uses Zod schemas to validate query parameters or request bodies.
• Type Safety: Infers input types directly from Zod schemas, preventing runtime errors.
• Boilerplate Reduction: Significantly reduces the lines of code needed for API routes.
• Use Case: When building a Next.js API endpoint that accepts user input via query parameters, use this skill to automatically validate that input against a defined Zod schema, returning a 400 error if validation fails.
