next-headers

next-headers

A (very) tiny wrapper to allow you to use Next.js's cookies() and headers() functions in your middleware.

Why would I need this?

Next.js's cookies() and headers() functions are only available in app directory. This means that if you want to use them in your middleware, you need to pass the request object from your middleware to every function down the stream. This can get messy, especially if you have multiple layers of middlewares, or if you have shared logic between your middleware and server code.

Warning

This plugin works only from next@13.4.4 ! If you are using an older version, please upgrade.

Installation

npm

npm install next-headers

Yarn

yarn add next-headers

Usage

Open your middleware.ts file and import the next-headers package:

import { withNextHeaders } from "next-headers";

Then, wrap your middleware with the withNextHeaders function:

export const middleware = withNextHeaders((request) => {
  // You can now use cookies() and headers() here
});

That's it! You can now use cookies() and headers() in your middleware.
