Next.js Middleware for Handling Post Requests | Tutorial web-beast.com

To create a TypeScript version of the middleware function for handling post requests in Next.js, you can follow me steps by steps:

Create a new file for your middleware: Create a new file in your Next.js project for your middleware, example

middleware/post.ts

Import the required types: In your new file, import the required types from the Next.js type definitions, for example:

import { NextApiRequest, NextApiResponse, NextApiHandler } from "next";

Define your middleware function: In your new file, define your middleware function with the proper types and with the

following signature: (req: NextApiRequest, res: NextApiResponse, next: NextApiHandler) => void.

You can add logic to handle post requests in this function. For example:

export default function postMiddleware(req: NextApiRequest, res: NextApiResponse, next: NextApiHandler) {
    if (req.method === "POST") {
      console.log("Handling a POST request");
      // Add your custom logic here
    }
    next();
  }

Apply the middleware: To apply the middleware, you can use the use method in your Next.js _app.tsx file. For example:

import postMiddleware from "../middleware/post";
import { AppProps } from "next/app";

function MyApp({ Component, pageProps }: AppProps) {
  use(postMiddleware);
  // ...
}
