# Server Middleware
|
|||
|
|
|
|||
|
|
Nuxt will automatically read in any files in the `~/server/middleware` to create server middleware for your project.
|
|||
|
|
|
|||
|
|
These files will be run on every request, unlike [API routes](./api) that are mapped to their own routes. This is typically so you can add a common header to all responses, log responses or modify the incoming request object for use later on in the request chain.
|
|||
|
|
|
|||
|
|
Each file should export a default function that will handle a request.
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
export default async (req, res) => {
|
|||
|
|
req.someValue = true
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
There is nothing different about the `req`/`res` objects, so typing them is straightforward.
|
|||
|
|
|
|||
|
|
```ts
|
|||
|
|
import type { IncomingMessage, ServerResponse } from 'http'
|
|||
|
|
|
|||
|
|
export default async (req: IncomingMessage, res: ServerResponse) => {
|
|||
|
|
req.someValue = true
|
|||
|
|
}
|
|||
|
|
```
