Learn how to use React, next-connect, Multer, and axios to upload files to your Next.js app

I am going to give a brief overview of how to upload files with React and Next.js API routes. In this article, I will assume you are familiar with adding npm packages and with using Next.js, and that you have created an API route before.

Below is a simple example of a Next.js API route.

export default (req, res) => {
  if (req.method === 'POST') {
    // Process a POST request
    res.status(200).json({ data: 'success' });
  } else {
    // Handle any other HTTP method
    res.status(405).json({ error: `Method '${req.method}' Not Allowed` });
  }
};

To make things easier when it comes to adding middleware to the API routes, we are going to use the next-connect library.
