Server-Side Validation for Registration Form with Zod🔥Next.js & MySQL Job Portal App #20
In part 20 of our Next.js and MySQL Job Portal series, we're diving into one of the most crucial parts of any application: server-side validation. Say goodbye to manual and messy validation logic! We'll install and implement Zod, a powerful TypeScript-first schema validation library.
In this tutorial, you'll learn how to create a robust registration schema, handle password confirmations using .extend() and .refine(), and automatically generate TypeScript types with z.infer(). We'll then integrate this schema into our Server Action, using safeParse() to securely validate incoming data and provide clear error messages. This is a must-watch for anyone looking to write safer, more maintainable code in their full-stack applications.
