Auth and Private Routes in Next.js 13

If you’re building a web application with Next.js 13 and using MongoDB as your database, you might be interested in handling authentication and private routes. In this article, we’ll take a look at how to set up authentication and create private routes using Next Auth Credentials.

Setting up Next Auth

First, install the required packages by running the following commands:

      
        npm install next-auth credentials mongodb
      
    

Once the packages are installed, you can set up Next Auth by creating a `pages/api/auth/[…nextauth].js` file and configure it to use MongoDB as the database.

Creating Private Routes

To create private routes, you can use the `getSession` function from Next Auth to check if a user is authenticated. If the user is not authenticated, you can redirect them to the login page. Here’s an example of how you can create a private route:

      
        import { getSession } from 'next-auth/client';

        export async function getServerSideProps(context) {
          const session = await getSession(context);

          if (!session) {
            return {
              redirect: {
                destination: '/login',
                permanent: false,
              },
            };
          }

          // Fetch data and pass it as props to the component
          return {
            props: { data },
          };
        }
      
    

Conclusion

By using Next Auth Credentials, you can easily set up authentication and create private routes in your Next.js 13 application. This allows you to secure certain parts of your app and provide a seamless login experience for your users. With the power of MongoDB as your database, you can store user credentials and manage authentication efficiently. Happy coding!
