How can I use Zod for data validation in my application?

Zod is a TypeScript-first schema declaration and validation library. You can define schemas for your data and validate them easily.

Can you show me a simple example of a Zod schema?

Sure! Here's a basic example:

import { z } from 'zod';

const userSchema = z.object({
  name: z.string(),
  age: z.number().min(18),
});

This schema validates that name is a string and age is a number that must be at least 18.

What happens if the validation fails?

If validation fails, Zod throws an error with details about what went wrong. You can catch this error to handle it gracefully.

Can I use Zod with TypeScript?

Absolutely! Zod is designed to work seamlessly with TypeScript, providing type inference based on your schemas.
