Next.js API Routes

Next.js is a popular framework for building React applications. It provides a way to create API routes for handling server-side logic. In this article, we will explore the basics of using Next.js API Routes to create a login form.

Setting up Next.js

First, you’ll need to install Next.js using npm or yarn. Once Next.js is installed, you can create a new project using the following command:

    
      npx create-next-app my-next-app
    
  

Creating an API Route

To create an API route in Next.js, you simply need to create a file in the `pages/api` directory with the desired endpoint name. For our login form, we can create a file named `login.js` with the following code:

    
      // pages/api/login.js
      export default function handler(req, res) {
        if (req.method === 'POST') {
          // Handle login logic here
          res.status(200).json({ message: 'Login successful' });
        } else {
          res.status(405).json({ message: 'Method not allowed' });
        }
      }
    
  

Creating a Login Form

Now that we have our API route set up, we can create a simple login form in our Next.js application. Here’s an example of a basic login form using HTML:

    
      <form action="/api/login" method="POST">
        <input type="text" name="username" placeholder="Username" />
        <input type="password" name="password" placeholder="Password" />
        <button type="submit">Login</button>
      </form>
    
  

Conclusion

Next.js API Routes provide a convenient way to handle server-side logic within a Next.js application. By creating a simple API route for our login form, we can easily integrate authentication into our application. This is just a basic example, but you can extend this concept to handle more complex server-side logic as needed.
