whoami.js

A simple and lightweight browser detection and logger library.

See demo page

Usage

// initialize whoami
var me = new whoami( [options] [, callback] );

// capture
me.execute();

The callback argument gets a data object with all catched informations.

Configuring whoami to communicate via API

// initialize whoami
var me = new whoami( urlApi [, options] [, callback] );

// capture
me.execute();

The callback argument gets 2 arguments:

1. An error when applicable (usually from XHR request)
2. A data object

See a server example using express.js

Options

name	type	default	description
basic	boolean	true	Basic browser informations (document title and url, user-agent, resolution, origin url and time)

cookie	boolean	false	Catch all cookies from domain
error	boolean	false	Catch all exceptions raised on the page
