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:
$ npm install on-headers
API
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 listeners are fired
in the reverse order they were added.
Examples
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
