Dev Dependencies

on-headers

Execute a listener when a response is about to write headers.

Installation

This is a Node.js module available through the npm registry. Installation is done using the npm install command:

1$ npm install on-headers

API

1var 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 listeners are fired in the reverse order they were added.

Examples

1var http = require('http')
2var onHeaders = require('on-headers')
3
4http
5  .createServer(onRequest)
6  .listen(3000)
7
8function addPoweredBy () {
9  // set if not set by end of request
10  if (!this.getHeader('X-Powered-By')) {
11    this.setHeader('X-Powered-By', 'Node.js')
12  }
13}
14
15function onRequest (req, res) {
16  onHeaders(res, addPoweredBy)
17
18  res.setHeader('Content-Type', 'text/plain')
19  res.end('hello!')
20}

Testing

1$ npm test
