The http module from node.js, but for browsers.


var http = require('http');

http.get({ path : '/beep' }, function (res) {
    var div = document.getElementById('result');
    div.innerHTML += 'GET /beep<br>';

    res.on('data', function (buf) {
        div.innerHTML += buf;

    res.on('end', function () {
        div.innerHTML += '<br>__END__';

http methods

var http = require('http');

var req = http.request(options, cb)

options can have:

  • method
  • path
  • headers={}, as an object mapping key names to string or Array values
  • port=window.location.port

The callback will be called with the response object.

var req = http.get(options, cb)

A shortcut for

options.method = 'GET';
var req = http.request(options, cb);

request methods

req.setHeader(key, value)

Set an http header.


Write some data to the request body.


Close and send the request body, optionally with additional data to append.

response methods


Return an http header, if set. key is case-insensitive.

response attributes

  • res.statusCode, the numeric http response code
  • res.headers, an object with all lowercase keys

response events

  • data
  • end
  • error


This module has been tested and works with:

  • Internet Explorer 5.5, 6, 7, 8, 9
  • Firefox 3.5
  • Chrome 7.0
  • Opera 10.6
  • Safari 5.0

Multipart streaming responses are buffered in all versions of Internet Explorer and are somewhat buffered in Opera. In all the other browsers you get a nice unbuffered stream of "data" events when you send down a content-type of multipart/octet-stream or similar.


You can do:

var bundle = browserify({
    require : { http : 'http-browserify' }

in order to map "http-browserify" over require('http') in your browserified source.
