How to Integrate Seamless Login and Sign-Up in Your React App

Creating a seamless login and sign-up experience is crucial for any modern web application. A smooth authentication flow not only enhances user experience but also boosts conversion rates and retention. In this guide, we’ll walk you through how to integrate user-friendly login and sign-up features into your React app using various libraries and strategies.

Why Seamless Login and Sign-Up Matter

A seamless authentication experience minimizes friction for users, making it easier for them to access your application. This fosters higher user satisfaction and decreases abandonment rates during the sign-up process. By integrating a robust authentication system, you ensure that user data is secure without compromising on user experience.

Prerequisites

Before we dive into the integration process, ensure you have the following:

• A basic understanding of React and JavaScript
• Node.js installed on your development machine
• A React app already set up (you can use Create React App)

Overview of Options

Several libraries can help you achieve seamless authentication in React. Some popular options include Firebase, Auth0, AWS Amplify, and Eartho. For this guide, we’ll be using Eartho due to its simplicity and comprehensive features.

Step 1: Set Up Your React App

If you don’t already have a React app, you can set one up using Create React App:‍
npx create-react-app my-auth-app
cd my-auth-app
npm start

Step 2: Install Eartho SDK

To integrate Eartho, start by installing the Eartho SDK:

npm install @eartho/eartho

Step 3: Initialize Eartho

Set up Eartho in your React app. Create a new file auth.js in your src directory and add the following code:‍

‍
import Eartho from '@eartho/eartho';

const eartho = new Eartho({
 clientId: 'YOUR_EARTHO_CLIENT_ID',
 domain: 'YOUR_EARTHO_DOMAIN',
});

export default eartho;

Replace YOUR_EARTHO_CLIENT_ID and YOUR_EARTHO_DOMAIN with your actual Eartho client ID and domain, which you can obtain from the Eartho dashboard.

Step 4: Create Authentication Components

Create login and sign-up components. First, add the login component in Login.js:

‍
import React from 'react';
import eartho from './auth';

const Login = () => {
 const handleLogin = async () => {
   await eartho.login();
 }

 return (
   <button onClick={handleLogin}>Login</button>
 );
}

export default Login;

Next, create the sign-up component in Signup.js:

‍
import React from 'react';
import eartho from './auth';

const Signup = () => {
 const handleSignup = async () => {
   await eartho.register();
 }

 return (
   <button onClick={handleSignup}>Sign Up</button>
 );
}

export default Signup;

Step 5: Incorporate the Components in Your App

Include the login and sign-up components in your main app file App.js:

‍
import React from 'react';
import Login from './Login';
import Signup from './Signup';

function App() {
 return (
   <div className="App">
     <header className="App-header">
       <h1>Welcome to My App</h1>
       <Login />
       <Signup />
     </header>
   </div>
 );
}

export default App;

Step 6: Run Your App and Test

Start your React app with npm start and navigate to http://localhost:3000 in your browser. You should see the "Login" and "Sign Up" buttons. Clicking either button will redirect you to the Eartho authentication flow.

Additional Features

Eartho offers more advanced features such as role-based access control, customizable UIs, integrated payments, and enhanced security features. Explore the Eartho documentation to fully utilize these capabilities in your application.
