NextJS + Auth0

NextJS is a popular React framework for building server-side rendered and static web applications. Auth0 is a leading identity and access management platform that provides authentication and authorization as a service. Combining NextJS with Auth0 allows developers to easily add user authentication and authorization to their applications.

Setting Up NextJS with Auth0

To get started with NextJS and Auth0, you’ll first need to sign up for an Auth0 account and create a new application. Once you have your Auth0 credentials, you can install the Auth0 SDK in your NextJS application by running the following command in your terminal:

npm install @auth0/nextjs-auth0

Next, you’ll need to create a new API in your Auth0 dashboard and configure the allowed callback URLs and logout URLs to match your NextJS application’s URLs. You’ll also need to configure the Auth0 SDK with your Auth0 domain and client ID.

Adding Authentication to NextJS Pages

With the Auth0 SDK installed and configured, you can now easily add authentication to your NextJS pages. You can use the getServerSideProps or getStaticProps functions to check for the user’s authentication status and fetch their user profile if they are logged in.

For example, you can create a protected route that checks if the user is authenticated and redirects them to the login page if they are not. You can also fetch the user’s profile and display their information on the page if they are logged in.

Securing API Routes with Auth0

If your NextJS application includes API routes, you can also secure these routes with Auth0. You can use the Auth0 SDK to validate the user’s access token and only allow authenticated users to access your API routes.

Conclusion

NextJS + Auth0 provides an easy way to add authentication and authorization to your NextJS applications. By combining the power of NextJS with the simplicity of Auth0, you can quickly build secure and user-friendly web applications.
