React Js Bootstrap Registration Form Example Tutorial

Quick Links :

In today's digital age, user registration forms are an essential part of any web application. They provide a secure way for users to create accounts and access exclusive content, services, or features. When it comes to building robust and scalable web applications, React Js and Bootstrap are two popular choices among developers.

React Js is a JavaScript library for building user interfaces, while Bootstrap is a CSS framework for styling and layout. Together, they provide a powerful combination for creating responsive, mobile-first, and visually appealing registration forms.

In this tutorial, we will guide you through the process of creating a React Js Bootstrap registration form example. We will cover the basic concepts, working mechanisms, and provide a step-by-step example to help you get started.

Why Use React Js and Bootstrap for Registration Forms?

Before we dive into the tutorial, let's explore the benefits of using React Js and Bootstrap for building registration forms.

• Faster Development: React Js and Bootstrap provide pre-built components and layouts, which speed up the development process.
• Responsive Design: Bootstrap's mobile-first approach ensures that your registration form looks great on all devices.
• Easy Customization: React Js and Bootstrap offer a wide range of customization options, allowing you to tailor your registration form to your brand's style.
• Improved User Experience: With React Js and Bootstrap, you can create a seamless and intuitive user experience for your users.

Step 1: Setting Up the Project Structure

To get started, create a new React Js project using your preferred method (e.g., create-react-app). Once you have your project set up, install the required Bootstrap dependencies:

npm install bootstrap react-bootstrap

Next, create a new component for your registration form. In this example, we'll call it RegistrationForm.js.

// RegistrationForm.js
import React, { useState } from 'react';
import { Form, Button, Container, Row, Col } from 'react-bootstrap';

const RegistrationForm = () => {
  // State to store form data
  const [formData, setFormData] = useState({
    name: '',
    email: '',
    password: '',
    confirmPassword: '',
  });

  // Handle form submission
  const handleSubmit = (event) => {
    event.preventDefault();
    console.log(formData);
  };

  // Handle input changes
  const handleChange = (event) => {
    setFormData({...formData, [event.target.name]: event.target.value });
  };

  return (
    
      
        
          

            
              Name
              
            
            
              Email
              
            
            
              Password
              
            
            
              Confirm Password
              
            
            
              Register
            
          
        
      
    
  );
};

export default RegistrationForm;

Step 2: Adding Form Validation

Form validation is an essential aspect of any registration form. It ensures that users enter valid data, reducing errors and improving the overall user experience.

To add form validation, we'll use the useState hook to store validation errors and update the form state accordingly.

// RegistrationForm.js (updated)
import React, { useState } from 'react';
import { Form, Button, Container, Row, Col } from 'react-bootstrap';

const RegistrationForm = () => {
  // State to store form data
  const [formData, setFormData] = useState({
    name: '',
    email: '',
    password: '',
    confirmPassword: '',
  });

  // State to store validation errors
  const [errors, setErrors] = useState({
    name: '',
    email: '',
    password: '',
    confirmPassword: '',
  });

  // Handle form submission
  const handleSubmit = (event) => {
    event.preventDefault();
    // Validate form data
    const validationErrors = validateForm(formData);
    if (Object.keys(validationErrors).length > 0) {
      setErrors(validationErrors);
    } else {
      console.log(formData);
    }
  };

  // Handle input changes
  const handleChange = (event) => {
    setFormData({...formData, [event.target.name]: event.target.value });
  };

  // Validate form data
  const validateForm = (data) => {
    const errors = {};
    if (!data.name.trim()) {
      errors.name = 'Name is required';
    }
    if (!data.email.trim() ||!/^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i.test(data.email)) {
      errors.email = 'Invalid email address';
    }
    if (!data.password.trim() || data.password.length < 8) {
      errors.password = 'Password must be at least 8 characters';
    }
    if (data.password!== data.confirmPassword) {
      errors.confirmPassword = 'Passwords do not match';
    }
    return errors;
  };

  return (
    //...
  );
};

export default RegistrationForm;
