Server-side mutations with Route Handlers in Next.js

Next.js has introduced a new API Routes feature in the app directory, which allows for server-side mutations with route handlers.

The new API Routes feature in Next.js app directory provides a way to handle server-side mutations in a more organized and structured manner. With route handlers, developers can define custom logic for handling requests and processing data on the server.

By using route handlers, developers can create custom API endpoints that can be accessed from the client-side application. This allows for more flexibility and control over how data is processed and manipulated on the server.

How to use Route Handlers

To use route handlers in a Next.js app, developers can create a new file in the `pages/api` directory and define the API endpoint logic using JavaScript. For example, if you want to create a custom API endpoint for handling user authentication, you can create a file called `auth.js` in the `pages/api` directory and define the authentication logic in that file.

Route handlers can be used to handle various types of server-side mutations, such as user authentication, data processing, and database queries. By organizing API endpoint logic into separate files, developers can maintain a clean and structured codebase, making it easier to manage and maintain server-side code.

Benefits of using Route Handlers

Route Handlers in Next.js app directory offer several benefits for developers:

• Organized and structured codebase: Route handlers allow developers to organize API endpoint logic into separate files, making it easier to manage and maintain server-side code.
• More control over server-side mutations: Route handlers provide a way to define custom logic for handling requests and processing data on the server, giving developers more flexibility and control over how data is manipulated.
• Increased reusability: With route handlers, developers can create reusable API endpoints that can be accessed from multiple client-side applications, reducing the need to duplicate code.

Overall, the new API Routes feature in Next.js app directory provides a powerful way to handle server-side mutations with route handlers. By organizing API endpoint logic into separate files and defining custom logic for handling requests and processing data on the server, developers can create more flexible, reusable, and maintainable server-side code.
