Angular jqLite

jQuery and Angular

Angular doesn’t depend on jQuery. In fact, the Angular source contains an embedded lightweight alternative: jqLite. Still, when Angular detects the presence of a jQuery version in your page, it uses that full jQuery implementation in lieu of jqLite. One direct way in which this manifests itself is with Angular’s element abstraction. For example, in a directive you get access to the element that the directive applies to:

They say that one of the pros of NodeJS is that you use the same language on the back-end and the front-end, so it's easy to share code between them. This sounds great in theory, but in practice the synchronous dependency handling in NodeJS works completely different than any client-side frameworks (which are asynchronous).

Usually that means that you end up copy-pasting your code between your NodeJS sources and your client-side sources, or you use some tool like Browserify, which is brilliant, but they add an extra step in the build process and most likely will conflict with the dependency handling of the framework of your choice (like AnularJS DI). I couldn't look in the mirror if I would call that code sharing.

Fortunately, with a couple of lines of boilerplate code, you can write a module which works in NodeJS and AngularJS as well without any modification.

No globals in the front-end, and dependencies will work. The isNode and isAngular va

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:
