#FAQ
|
|
|
|
### Why is this project called "angular"? Why is the namespace called "ng"?
|
|
|
|
Because HTML has angular brackets and "ng" sounds like "angular".
|
|
|
|
### Is <angular/> an HTML5 tag?
|
|
|
|
No, <angular/> is not an HTML5 tag. angular is an orthogonal project to HTML5; you can use the two
|
|
together.
|
|
|
|
### Is angular a {library, framework, DOM manipulation library, widget library, native plugin}?
|
|
|
|
No, angular is none of these. You don't call its functions, it does not call your functions,
|
|
it does not provide a way to manipulate DOM, but does provide primitives to create UI projections
|
|
of your data. There are lots of existing widget libraries which you can integrate with angular.
|
|
It is 100% JavaScript, 100% client side and compatible with both desktop and mobile browsers.
|
|
|
|
### Do I need to worry about security holes in angular?
|
|
|
|
Like with any technology, angular is not impervious to attack. angular does, however, provide
|
|
built-in protection from basic security holes including cross-site scripting and HTML injection
|
|
attacks. angular does round-trip escaping on all strings for you.
|
|
|
|
### Can I download the source, build, and host the angular environment locally?
|
|
|
|
Yes. See instructions in {@link downloading downloading}.
|
|
|
|
### Is angular a templating system?
|
|
|
|
At the highest level, angular does look like a just another templating system. But there is one
|
|
important reason why angular templating system is different and makes it very good fit for
|
|
application development: bidirectional data binding. The template is compiled on the browser and
|
|
the compilation step produces a live view. This means you, the developer, don't need to write
|
|
code to constantly sync the view with the model and the model with the view as in other
|
|
templating systems.
|
|
|
|
### What browsers does angular work with?
|
|
|
|
Webkit-based browsers (Safari, Chrome, iPhone, Android, WebOS, BlackBerry 6), Firefox, IE6 and
|
|
above. Note that CSS only works on IE7 and above.
|
|
|
|
### What's angular's performance like?
|
|
|
|
angular takes ~300ms to load, render, and compile. In Chrome it uses about 2-5MB of memory. Your
|
|
app's performance will vary depending on how many bindings you use.
|
|
|
|
### How big is the angular bootstrap JS file that I need to include?
|
|
|
|
The size of the library itself is < 50KB compressed and obfuscated.
|
|
|
|
### Can I use the open-source Closure Library with angular?
|
|
|
|
Yes, you can use widgets from the {@link http://code.google.com/closure/library Closure Library}
|
|
in angular.
|
|
|
|
### Does angular use the jQuery library?
|
|
|
|
Yes, angular uses {@link http://jquery.com/ jQuery}, the open source DOM manipulation library.
|
|
If jQuery is not present in your script path, angular falls back on its own implementation of
|
|
{@link angular.element jQuery lite}. If jQuery is present in the path, angular uses it to
|
|
manipulate the DOM.
|
|
|
|
### What is testability like in angular?
|
|
|
|
Very testable. It has an integrated dependency injection framework. See
|
|
{@link angular.service service} for details.
|
|
|
|
### How can I learn more about angular?
|
|
|
|

|

|
### How is angular licensed?
|
|
