Prerequisites

To complete the "Stytch Authentication in React Next.js" tutorial, you will need to have the following prerequisites:

• Basic knowledge of React and Next.js
• Node.js and npm installed on your machine
• A Stytch account and API key
• A text editor or integrated development environment (IDE) such as Visual Studio Code or WebStorm
• Basic knowledge of HTML, CSS, and JavaScript
• Familiarity with Git and version control

Having these prerequisites will ensure that you have the necessary knowledge and tools to follow along with the tutorial and implement Stytch authentication in your React Next.js application. If you are new to React or Next.js, it may be helpful to review some introductory tutorials or documentation before starting this tutorial. Additionally, if you are new to Stytch, it may be helpful to review their documentation and API reference to familiarize yourself with their authentication platform.

React Next.js Stytch step by step setup and configuration

Integrating Stytch into a React Next.js project is a straightforward process that involves a few key steps. First, you will need to install the Stytch SDK and configure it with your API key. Next, you will need to create the necessary authentication routes and components in your React Next.js application. Finally, you will need to implement the Stytch authentication flow in your application, allowing users to log in and access protected content.

To install the Stytch SDK, you can use npm or yarn to add the @stytch/stytch package to your project. Once installed, you can configure the SDK with your API key using the Stytch.init method. This should be done in a file that is loaded before any other Stytch-related code, such as your pages/_app.js file.

import Stytch from '@stytch/stytch';

Stytch.init('YOUR_API_KEY');

Next, you will need to create the necessary authentication routes and components in your React Next.js application. This will typically involve creating a login page, a registration page, and any other necessary pages or components for handling authentication. You can use the Stytch.magicLink.loginOrCreate method to handle the login or registration flow, which will send a magic link to the user's email address.

import Stytch from '@stytch/stytch';

const handleLogin = async (email) => {
  const response = await Stytch.magicLink.loginOrCreate(email);
  // Handle response
};

const LoginPage = () => {
  const [email, setEmail] = useState('');

  const handleSubmit = (event) => {
    event.preventDefault();
    handleLogin(email);
  };

  return (
    <form onSubmit={handleSubmit}>
      <label>
        Email:
        <input type="email" value={email} onChange={(e) => setEmail(e.target.value)} />
      </label>
      <button type="submit">Log in</button>
    </form>
  );
};

Finally, you will need to implement the Stytch authentication flow in your application. This will typically involve handling the magic link that is sent to the user's email address and redirecting them to the appropriate page or component once they are authenticated. You can use the Stytch.magicLink.handleLoginResponse method to handle the response from Stytch and redirect the user to the appropriate page.

import Stytch from '@stytch/stytch';
import { useRouter } from 'next/router';

const handleLoginResponse = async (response) => {
  // Handle response
  const router = useRouter();
  router.push('/dashboard');
};

const MagicLinkPage = () => {
  useEffect(() => {
    const params = new URLSearchParams(window.location.search);
    const token = params.get('token');
    if (token) {
      Stytch.magicLink.handleLoginResponse(token).then(handleLoginResponse);
    }
  }, []);

  return <div>Logging in...</div>;
};

By following these steps and implementing the relevant code blocks, you can easily integrate Stytch authentication into your React Next.js application.

Stytch configuration options in React Next.js

When integrating Stytch authentication into a React Next.js application, there are several configuration options that can be used to customize the authentication flow and user experience. These options include:

• loginMagicLinkUrl: The URL that users will be redirected to when they click the magic link in their email. This should be set to a page or component in your application that will handle the magic link and log the user in.
• signupMagicLinkUrl: The URL that users will be redirected to when they click the magic link to create a new account. This should be set to a page or component in your application that will handle the magic link and create the new account.
• loginOrCreateMagicLinkUrl: The URL that users will be redirected to when they click the magic link to either log in or create a new account. This should be set to a page or component in your application that will handle the magic link and either log the user in or create a new account.
• magicLinkValiditySeconds: The number of seconds that the magic link will be valid for. This should be set to a reasonable value based on your application's security requirements and user experience.
• magicLinkEmailTemplate: The email template that will be used to send the magic link to the user's email address. This can be customized to match your application's branding and messaging.
• magicLinkSMSBodyTemplate: The SMS template that will be used to send the magic link to the user's phone number. This can be customized to match your application's branding and messaging.
• magicLinkFromEmail: The email address that the magic link email will be sent from. This should be set to a valid email address that you control.
• magicLinkFromSMS: The phone number that the magic link SMS will be sent from. This should be set to a valid phone number that you control.
• magicLinkLoginSuccessUrl: The URL that users will be redirected to after they successfully log in using the magic link. This should be set to a page or component in your application that will display the user's dashboard or other protected content.

By using these configuration options, you can customize the Stytch authentication flow to match your application's requirements and user experience.
