I'm using pace.js to have a bar loader before app.js load, but it isn't really nice. In case of fast or not fast connection the bar arrives to 99% and stop here for some time.
I've seen that i can set a gif like mask, but is it possible to have a progress bar instead of a gif?
Others solutions instead of pace.js are accepted.
Resolved my problem using a connection speed detector before load my app js, and calculating how much time it gives to be load.
Before starting pace i detect the speed and set pace params dinamically.
Sometimes not really perfect but it is pretty good.
Thanks.
