React login page template Source Code

In today's web development landscape, creating an engaging and user-friendly login page is crucial for any application. This article will guide you through the process of building a feature-rich, swipeable login page using React. We'll create a modern, responsive design that seamlessly transitions between login and signup modes, complete with animated transitions and social media login options.

Setting Up the Project

First, ensure you have React set up in your project. We'll also be using a few additional libraries:

• Framer Motion for animations
• Lucide React for icons
• Tailwind CSS for styling

You can install these dependencies using npm or yarn:

npm install react framer-motion lucide-react
# or
yarn add react framer-motion lucide-react

Make sure you have Tailwind CSS configured in your project as well.

Creating the Login/Signup Component

Let's start by creating our main component, LoginSignupPage. This component will handle the state and rendering of our login/signup form.

import React, { useState } from 'react';
import { motion, AnimatePresence } from 'framer-motion';
import { Mail, Lock, User, ArrowRight, Github, Twitter } from 'lucide-react';

const LoginSignupPage = () => {
  const [isLogin, setIsLogin] = useState(true);
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');
  const [name, setName] = useState('');

  const toggleMode = () => setIsLogin(!isLogin);

  // ... (rest of the component)
};

export default LoginSignupPage;

Here, we're importing the necessary dependencies and setting up our component with state variables for the form fields and a toggle for switching between login and signup modes.

Creating Reusable Input Fields

To keep our code DRY (Don't Repeat Yourself), let's create a reusable InputField component:

const InputField = ({ icon: Icon, placeholder, type, value, onChange }) => (
  <div className="flex items-center bg-gray-100 p-3 rounded-lg">
    <Icon className="text-gray-500 mr-3" size={20} />
    <input
      type={type}
      placeholder={placeholder}
      value={value}
      onChange={onChange}
      className="bg-transparent outline-none flex-1 text-gray-800"
    />
  </div>
);

This component takes an icon, placeholder text, input type, value, and onChange function as props. It renders a styled input field with an icon, making our form look sleek and consistent.

Building the Form

Now, let's create the main structure of our login/signup form:

return (
  <div className="flex flex-col md:flex-row h-screen bg-gray-100">
    <div className="w-full md:w-1/2 bg-white flex items-center justify-center p-8 md:p-16">
      <div className="w-full max-w-md">
        <AnimatePresence mode="wait">
          <motion.div
            key={isLogin ? 'login' : 'signup'}
            initial="hidden"
            animate="visible"
            exit="hidden"
            variants={formVariants}
            transition={{ duration: 0.3 }}
          >
            <h1 className="text-3xl md:text-4xl font-bold mb-8 text-gray-800">
              {isLogin ? 'Welcome back' : 'Create account'}
            </h1>
            <div className="space-y-4">
              {!isLogin && (
                <InputField 
                  icon={User} 
                  placeholder="Full Name" 
                  type="text" 
                  value={name} 
                  onChange={(e) => setName(e.target.value)} 
                />
              )}
              <InputField 
                icon={Mail} 
                placeholder="Email" 
                type="email" 
                value={email} 
                onChange={(e) => setEmail(e.target.value)} 
              />
              <InputField 
                icon={Lock} 
                placeholder="Password" 
                type="password" 
                value={password} 
                onChange={(e) => setPassword(e.target.value)} 
              />
            </div>
            {/* ... (submit button and social login options) */}
          </motion.div>
        </AnimatePresence>
      </div>
    </div>
    {/* ... (right side panel) */}
  </div>
);

This code creates a responsive layout with the form on the left side. We use Framer Motion's AnimatePresence and motion.div to add smooth transitions when switching between login and signup modes.

Adding the Submit Button and Social Login Options

Let's add a submit button and social login options to our form:

<div className="mt-8">
  <button
    className={`text-white px-6 py-3 rounded-lg w-full flex items-center justify-center ${isLogin ? 'bg-blue-600' : 'bg-green-600'}`}
  >
    {isLogin ? 'Sign In' : 'Sign Up'} <ArrowRight className="ml-2" size={20} />
  </button>
</div>
{isLogin && (
  <div className="mt-6 flex justify-center space-x-4">
    <button className="p-2 bg-gray-200 rounded-full">
      <Github className="text-gray-700 hover:text-white" size={24} />
    </button>
    <button className="p-2 bg-gray-200 rounded-full">
      <Twitter className="text-gray-700 hover:text-white" size={24} />
    </button>
  </div>
)}

This code adds a submit button that changes color and text based on the current mode (login or signup). For the login mode, we also add social login options for GitHub and Twitter.

Creating the Swipeable Side Panel

To complete our swipeable login page, let's add a side panel that allows users to switch between login and signup modes:

<div 
  className={`w-full md:w-1/2 flex items-center justify-center p-8 md:p-16 ${isLogin ? 'bg-blue-600' : 'bg-green-600'}`}
>
  <div className="text-center">
    <h2 className="text-3xl md:text-4xl font-bold mb-6 text-white">
      {isLogin ? 'New here?' : 'Already have an account?'}
    </h2>
    <p className="text-gray-200 mb-8">
      {isLogin 
        ? 'Sign up and discover a great amount of new opportunities!' 
        : 'Sign in to access your account and continue your journey!'}
    </p>
    <button
      className="bg-white px-6 py-3 rounded-lg"
      style={{ color: isLogin ? '#2563EB' : '#059669' }}
      onClick={toggleMode}
    >
      {isLogin ? 'Sign Up' : 'Sign In'}
    </button>
  </div>
</div>

This side panel changes its content and color based on the current mode. The button allows users to switch between login and signup modes, triggering the toggleMode function we defined earlier.

Adding Animations

To make our login page more engaging, we've used Framer Motion for animations. Here's how we defined the animation variants:

const formVariants = {
  hidden: { opacity: 0, x: -30 },
  visible: { opacity: 1, x: 0 },
};

These variants are applied to the motion.div wrapping our form, creating a smooth transition effect when switching between login and signup modes.
