+
+Execute a listener when a response is about to write headers.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install on-headers
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var onHeaders = require('on-headers')
+```
+
+### onHeaders(res, listener)
+
+This will add the listener `listener` to fire when headers are emitted for `res`.
+The listener is passed the `response` object as it's context (`this`). Headers are
+considered to be emitted only once, right before they are sent to the client.
+
+When this is called multiple times on the same `res`, the `listener`s are fired
+in the reverse order they were added.
+
+## Examples
+
+```js
+var http = require('http')
+var onHeaders = require('on-headers')
+
+http
+  .createServer(onRequest)
+  .listen(3000)
+
+function addPoweredBy () {
+  // set if not set by end of request
+  if (!this.getHeader('X-Powered-By')) {
+    this.setHeader('X-Powered-By', 'Node.js')
+  }
+}
+
+function onRequest (req, res) {
+  onHeaders(res, addPoweredBy)
+
+  res.setHeader('Content-Type', 'text/plain')
+  res.end('hello!')
+}
+```
+
+## Testing
+
+```sh
+$ npm test
+```
