When working with forms in React, it's common to use form management libraries to simplify state handling, validation, and submission. You can supercharge these libraries by integrating schema validation libraries for cleaner and more scalable code.

🚀 Form Management Libraries (React)

These libraries help manage form inputs, handle user input, validations, and submission flow:

Library Key Features
React Hook Form Lightweight, minimal re-renders, great with TypeScript + Zod
Formik Easy to use, very popular, pairs well with Yup
React Final Form Declarative and flexible, based on Final Form core
Unform Fast, developer-friendly, built by Rocketseat
Informed Extensible and simple
TanStack Form Experimental but promising, by the creators of TanStack Query/Table

🔸 These libraries manage form state, validation, error display, and submission efficiently.

📜 Schema Validation Libraries

To enforce validation rules declaratively and consistently:

Library Notes
Zod Great with TypeScript, strict and developer-friendly
Yup Most popular with Formik, intuitive and readable syntax
Joi Common in backend (Node.js), can be reused in frontend
Superstruct Lightweight and powerful schema definition
AJV Works with JSON Schema, great for dynamic form rendering

🔗 Integration = Power Combo 💪

To combine form library + schema validator, you use a resolver. This allows your form library to understand the schema validation rules.

Example: React Hook Form + Zod 

npm install react-hook-form zod @hookform/resolvers
import { useForm } from 'react-hook-form';
import { zodResolver } from '@hookform/resolvers/zod';
import { z } from 'zod';

const schema = z.object({
  name: z.string().min(3, { message: 'Name is too short' }),
  age: z.number().min(18, { message: 'You must be at least 18' }),
});

const { register, handleSubmit, formState: { errors } } = useForm({
  resolver: zodResolver(schema),
});

✅ resolver connects your form handler (React Hook Form) with the schema validator (Zod, Yup, etc.).

  • Use a form management library like React Hook Form or Formik to manage form states.

  • Pair it with a schema validator like Zod or Yup.

  • Install and configure a resolver to bridge them together.

  • Use TypeScript to get full type-safety with z.infer!
