How to post Request with Next Js?

Next.js stands out as a powerful React framework that simplifies the creation of fast and user-friendly applications. Among its many features, the ability to handle server-side operations seamlessly is a game-changer. In this post, we’ll dive into the specifics of how to make a POST request with Next.js, an essential skill for developers looking to harness the full potential of modern web applications.

What's Next Js and how to install it

Next.js is a React framework used for building web applications. It enables features like server-side rendering and static site generation, which can improve performance and user experience. It also provides automatic code splitting, optimized loading, and simplified data fetching.

To install Next.js, you should have Node.js version 18.17 or later. Open your terminal and run the following command to create a new Next.js app:

npx create-next-app@latest

Follow the prompts to name your project and configure options like TypeScript, ESLint, and Tailwind CSS if desired. After installation, you can start developing your application using the React components and Next.js features.

What POST request is used for?

A POST request is a method used in the Hypertext Transfer Protocol (HTTP) to send data to a server, typically to create or update a resource. The data is included in the body of the request, rather than in the URL as with a GET request.

POST requests are commonly used when you want to create or update a resource on the server.

How to make post request with Next JS    

To make a POST request in Next.js, you can use the built-in API routes feature. Here’s a simple example of how to set up an API route that handles POST requests:

1. Create a file under pages/api/, for example, user.js.
2. Inside this file, export a default function that handles the incoming req (request) and res (response) objects.
3. Check the request method to ensure it’s a POST request.
4. Process the request body and return a response.

// pages/api/user.js
export default function handler(req, res) {
  if (req.method === 'POST') {
    // Process POST request
    const data = req.body; // Your request's body
    // ...do something with the data...
    res.status(200).json({ message: 'Data received', data });
  } else {
    // Handle any other HTTP method
    res.setHeader('Allow', ['POST']);
    res.status(405).end(`Method ${req.method} Not Allowed`);
  }
}

In your front-end code, you can make a POST request to this API route using fetch:

// Example of making a POST request in a Next.js page or component
const postData = async () => {
  const response = await fetch('/api/user', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      key: 'value', // Replace with your data
    }),
  });

  const result = await response.json();
  console.log(result);
};

// Call postData when needed, for example in an event handler
