React Hook Form Validation Tutorial | Validate Forms with API Errors (CRUD Tutorial - Ep 27)

📌 In Episode 27 of the React 19 Full Stack Masterclass, we continue building our Users CRUD module by implementing form validation and error handling using React Hook Form. In the previous episode, we created the Create User form and integrated it with our Laravel backend API. However, the form did not yet include proper validation or error handling. In this episode, we will improve our form by implementing both client-side and server-side validation. We will learn how to use React Hook Form to add validation rules, display error messages, and handle validation responses returned from the Laravel API. By the end of this episode, our Create User form will be fully validated and ready for real-world usage. 📚 What You Will Learn in This Episode ✅ Why form validation is important in modern web applications ✅ How to implement client-side validation using React Hook Form ✅ How to validate fields like name, email, password, and confirm password ✅ How to display validation error messages in React ✅ How to handle Laravel backend validation errors inside React forms ✅ How to map API validation errors using React Hook Form setError() ✅ Best practices for building scalable and user-friendly forms 🧰 Technologies Used ✅ React 19 ✅ Laravel 12 ✅ Laravel Sanctum ✅ React Router v7 ✅ React Context API ✅ React Hook Form ✅ Tailwind CSS ✅ REST API 📺 Series Progress So far in this masterclass we have built: ✅ Authentication using Laravel Sanctum ✅ Login and registration APIs ✅ Global authentication state with React Context ✅ Protected routes using React Router ✅ Users List (Read operation) ✅ Create User form (Create operation) ✅ Form validation using React Hook Form In the next episode, we will continue our CRUD journey and implement the Edit User feature, where we will learn how to pre-fill form data and update existing records.
