SuperTokens Authentication in React Next.js

SuperTokens Authentication in React Next.js

In today's digital age, security is of utmost importance. With the rise of cyber attacks and data breaches, it is crucial for web applications to have robust authentication systems in place. SuperTokens is a powerful open-source solution that provides secure and scalable authentication for web applications. In this tutorial, we will explore how to integrate SuperTokens authentication into a React Next.js application.

React Next.js is a popular framework for building server-side rendered React applications. It provides a powerful set of tools for building complex web applications, including server-side rendering, automatic code splitting, and optimized performance. By integrating SuperTokens authentication into a React Next.js application, we can ensure that our application is secure and scalable, while also taking advantage of the powerful features provided by Next.js. In this tutorial, we will walk through the process of setting up SuperTokens authentication in a React Next.js application, from installation to implementation.

What is SuperTokens?

SuperTokens Authentication is an open-source solution that provides secure and scalable authentication for web applications. It is designed to be easy to use and integrate into existing applications, while also providing robust security features to protect against common attacks such as cross-site scripting (XSS) and cross-site request forgery (CSRF).

SuperTokens Authentication uses a token-based authentication system, where users are issued a unique token upon successful login. This token is then used to authenticate subsequent requests to the server, ensuring that only authenticated users are able to access protected resources. SuperTokens also provides features such as multi-factor authentication, passwordless authentication, and social login integration, making it a versatile solution for a wide range of web applications. Overall, SuperTokens Authentication is a powerful tool for ensuring the security and scalability of web applications, and is a popular choice for developers looking to implement robust authentication systems.

Prerequisites

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

• Basic knowledge of React and Next.js: This tutorial assumes that you have a basic understanding of React and Next.js, including how to create components, routes, and pages.
• Node.js and npm: You will need to have Node.js and npm installed on your machine to install and run the required packages and dependencies.
• A code editor: You will need a code editor such as Visual Studio Code or Sublime Text to write and edit code.
• SuperTokens account: You will need to create a SuperTokens account to obtain the necessary API keys and credentials for authentication.
• A web browser: You will need a web browser such as Chrome or Firefox to test and view the application.

React Next.js SuperTokens step by step setup and configuration

Integrating SuperTokens into a React Next.js project is a straightforward process that involves installing the necessary packages and configuring the authentication system. Here are the steps to follow:

1. Install the necessary packages: To use SuperTokens in your React Next.js project, you will need to install the supertokens-auth-react and supertokens-node packages. You can do this by running the following command in your terminal:

npm install supertokens-auth-react supertokens-node

2. Configure the SuperTokens middleware: Next, you will need to configure the SuperTokens middleware in your Next.js application. This involves creating a supertokens.js file in your project's root directory and adding the following code:

const { middleware } = require("supertokens-node");

middleware({
  apiPath: "/auth",
  supertokens: {
    connectionURI: "https://your-supertokens-domain.com",
    apiKey: "your-api-key",
  },
});

This code sets up the SuperTokens middleware with the necessary configuration options, including the API path and connection URI.

3. Add the SuperTokens provider: Next, you will need to add the SuperTokens provider to your React application. This can be done by wrapping your application with the SuperTokensProvider component, as shown in the following code:

import { SuperTokensProvider } from "supertokens-auth-react";

function MyApp({ Component, pageProps }) {
  return (
    <SuperTokensProvider>
      <Component {...pageProps} />
    </SuperTokensProvider>
  );
}

export default MyApp;

This code wraps your application with the SuperTokensProvider component, which provides the necessary context for authentication.

4. Use the useSession hook: Finally, you can use the useSession hook to access the user's session information and perform authentication checks. Here is an example of how to use the useSession hook in a React component:

import { useSession } from "supertokens-auth-react";

function Profile() {
  const { session } = useSession();

  if (!session) {
    return <div>You are not logged in</div>;
  }

  return (
    <div>
      <h1>Welcome, {session.user.email}</h1>
      <button onClick={() => signOut()}>Sign out</button>
    </div>
  );
}

This code uses the useSession hook to access the user's session information and display a welcome message if the user is logged in. It also provides a button to sign out of the application.

By following these steps, you can easily integrate SuperTokens authentication into your React Next.js project and provide a secure and scalable authentication system for your users.

SuperTokens configuration options in React Next.js

Here are the SuperTokens configuration options for React Next.js integration:

• apiPath: The API path for SuperTokens authentication endpoints.
• supertokens: An object containing the following options:
  • connectionURI: The connection URI for your SuperTokens instance.
  • apiKey: Your SuperTokens API key.
  • refreshAPICustomHeaders: Custom headers to be sent with the refresh API request.
  • cookieDomain: The domain for the SuperTokens cookie.
  • cookieSecure: Whether to use secure cookies or not.
  • cookieSameSite: The SameSite attribute for the SuperTokens cookie.
  • sessionExpiredStatusCode: The HTTP status code to return when a session has expired.
  • sessionRefreshFeature: Whether to enable the session refresh feature or not.
  • sessionRefreshInterval: The interval at which to refresh the session.
  • sessionScope: The scope of the SuperTokens session cookie.
  • sessionCookieName: The name of the SuperTokens session cookie.
  • accessTokenPath: The path for the access token cookie.
  • refreshTokenPath: The path for the refresh token cookie.
  • enableAntiCsrf: Whether to enable anti-CSRF protection or not.
  • accessTokenBlacklistingEnabled: Whether to enable access token blacklisting or not.
  • enableJwtPayloadChecking: Whether to enable JWT payload checking or not.
  • jwtSigningPublicKey: The public key for JWT signing.
  • jwtSigningPrivateKey: The private key for JWT signing.
  • jwtSigningAlgorithms: The algorithms to use for JWT signing.

These configuration options allow you to customize the behavior of SuperTokens in your React Next.js application, including the API path, connection URI, cookie settings, session refresh interval, and more. By configuring these options to meet the specific needs of your application, you can ensure that your authentication system is secure, scalable, and reliable.
