Creating a Sign-up Form in React | MERN Authentication & Authorization

In this article, we will learn how to create a sign-up form in React for a MERN (MongoDB, Express, React, Node.js) authentication and authorization system.

Step 1: Setting up the React App

First, let’s create a new React app using create-react-app:

  npx create-react-app sign-up-form

Step 2: Creating the Sign-up Form Component

Next, let’s create a new component called SignUpForm.js in the src/components directory:

  import React, { useState } from 'react';

const SignUpForm = () => {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');

  const handleSignUp = () => {
    // Handle sign-up logic here
  }

  return (
    <div>
      <h2>Sign Up</h2>
      <input
        type="email"
        placeholder="Email"
        value={email}
        onChange={(e) => setEmail(e.target.value)}
      />
      <input
        type="password"
        placeholder="Password"
        value={password}
        onChange={(e) => setPassword(e.target.value)}
      />
      <button onClick={handleSignUp}>Sign Up</button>
    </div>
  );
}

export default SignUpForm;

Step 3: Using the Sign-up Form Component in App.js

Now, let’s use the SignUpForm component in the App.js file:

  import React from 'react';
import SignUpForm from './components/SignUpForm';

const App = () => {
  return (
    <div>
      <h1>MERN Authentication & Authorization</h1>
      <SignUpForm />
    </div>
  );
}

export default App;

Step 4: Connecting the Sign-up Form to the Backend

Finally, we need to add logic to handle the sign-up form submission on the backend. This typically involves making an HTTP request to a server that will handle the sign-up process and store the user’s information in a database.

That’s it! You now have a basic sign-up form in React for a MERN authentication and authorization system. Happy coding!
