Simple "pixel" library for component, inspired heavily by superagent.

$ component install redventures/pixel

Instantitates a new pixel for the given type. The supported types are:

• image
• script

var pixel = require('pixel');

pixel('image')
  .send({ key1: 'value1' })
  .send({ key2: 'value2' })
  .end();

pixel('script')
  .send('key1', 'value1')
  .send('key2', 'value2')
  .end(function(){
    // optional callback
  });

Appends key=value as a querystring parameter of the pixel request. Note that this will urlencode the values for you.

pixel('image')
  .send('key1', 'value 1')
  .send({ key2: 'value 2' })
  .send({ 
    key3: 'value 3',
    key4: 'value 4'
  })
  .end();

Sets the configuration value for the request. If you want to change it for all requests, see .defaults().

pixel('script')
  .set('host', 'foo.com')
  .set('path', '/bar.js')
  .send('key', 'value')
  .end();

Sends the actual HTTP request for the pixel, invoking the optional callback.

Sets the defaults for every pixel instantiated. The options and predefined defaults are:

• host: Remote hostname. Defaults to location.hostname.
• path: Remote path. Defaults to /pixel.
• protocol: Remote protocol. Defaults to location.protocol
• cacheBust: Whether to append a random "cache bust" to the URL.

var pixel = require('pixel');

pixel.defaults({
  host: '//google.com',
  path: '/api'
});

pixel('script')
  .send('key', 'value')
  .end();

• more tests, specially IE and mobile.
• passing responses back to .end(callback). Probably only for script type.
