AngularJS Tips / Progress bar on route change

If you need an effect of progressbar-like between different states of an application. Here is quick and dirty solution.

Dependencies

• ui-router - of course you can use ngRoute, but I don't recommend so.
• ngprogress-lite github official page - to get filling how it's works follow to the official page and look on the top of the page;

Ideal

Use something like that between states:

$rootScope.$on('$stateChangeStart', function(){
  ngProgressLite. start ();
});

$rootScope.$on('$stateChangeSuccess', function(){
  ngProgressLite.done();
});

$rootScope.$on('$stateChangeError',  function(){
  ngProgressLite.done();
});

and fetch all needed dependencies in the resolve section of the states.

Good luck.

Creation of documentation for JavaScript library

If you are developing open source library one of most important things is documentation and it's great if it has good design. But anyway, it's better to have a badly designed documentation than none at all.
So here i'll describe of some tectonics (jsdoc, unittests, grunt) to apply documentation for your opensource project.

Parallax / On Darlingjs

Here is short article about creating parallax effect upon game engine darlingjs

What is the parallax?

In our case parallax is an effect of perception that takes place when 3D environment is translated into 2D display surface. For example we have an observer with 'view port' (2D) and some objects on different distance from the observer in 3D. If the observer takes left or right step than visually objects located nearby will move faster than objects located further away from the observer. If an object is placed very far from the observer for a short period of time it will look as if it doesn't move at all, like the sun for the observer on the Earth.

Cyclic background / On Darlingjs

Goal

One of the issue i got during developing of the 2D game Red Cabriolet was creation of landscape with taste of 3D environment. In other words:

• the landscape mast be unlimited;
• placed behind the main stage;
• and gives feeling of 3D space in 2D;

Anons of DarlingJS and Red Cabriolet

I'm developing flexible javascript game engine darling.js and also the game Red Cabriolet as example of possibilities of engine. So any comments and feedback is welcome.
