Review on Alertify Js by Dave Rasic

The ability to use this with nodejs, which makes it easy when you want something like that! It's not too clear how I can add my own icons (I know there are free ones out here but they don't look professional enough).

Have been using alertifying js in some of our projects where we wanted custom messages or warnings etc., so as far i have seen people seem happy about its ease-of -use especially since most JS solutions tend towards being heavy weight at times.- We started off by just putting an if statement inside one function then another depending what state was set from server side code via AJAX calls; however now all alerts go through 1 single interface instead.
