nextjs starter template with auth

  1. Install Next.js: Start by installing Next.js using either npm or yarn. Next.js is a React framework for building server-side rendered (SSR) applications.

  2. Create a new Next.js project: Use the Next.js CLI to create a new project. Open your terminal and run the following command:

npx create-next-app my-app

This will create a new Next.js project in a folder named "my-app".

  1. Set up authentication: Next.js doesn't have built-in authentication, so we'll need to add a library to handle this. One popular library for authentication in Next.js is NextAuth.js. To install it, navigate to your project folder and run:

npm install next-auth

  1. Configure NextAuth.js: NextAuth.js requires some configuration to work properly. Create a new file called [...nextauth].js in the pages/api/ directory. This file will handle the authentication logic.

Inside the [...nextauth].js file, you'll need to define your authentication providers, such as Google, Facebook, or local authentication. You can also configure other options like session management and callbacks.

  1. Create the login page: Next, create a new file called login.js in the pages/ directory. This file will serve as your login page. You can use any UI library or custom design for this page.

Inside the login.js file, you'll need to import the necessary components from NextAuth.js to handle the login logic. You can use the signIn() function provided by NextAuth.js to initiate the authentication process.

  1. Create the protected route: In Next.js, you can create protected routes by using server-side rendering (SSR) and checking the user's authentication status before rendering the page. Create a new file called protected.js in the pages/ directory.

Inside the protected.js file, you'll need to import the necessary components from NextAuth.js to check the user's authentication status. If the user is authenticated, render the protected content. Otherwise, redirect them to the login page.

  1. Test the authentication flow: Start your Next.js development server by running the following command in your terminal:

npm run dev

Open your browser and navigate to http://localhost:3000. You should see your Next.js application running.

Test the authentication flow by trying to access the protected route. If you're not logged in, you should be redirected to the login page. After logging in, you should be able to access the protected route and see the protected content.

  1. Customize the authentication flow: You can customize the authentication flow by modifying the login page, adding sign up functionality, or implementing any additional features you need. NextAuth.js provides various functions and configuration options to customize the authentication flow according to your requirements.

Refer to the NextAuth.js documentation for more details on how to customize the authentication flow.

That's it! You now have a Next.js starter template with authentication using NextAuth.js. You can further enhance your application by adding features like user roles, email verification, or integrating with other authentication providers.
