Differentiators
- Two-way data binding
- Dependency injection
- Extending HTML vocabulary
Two-Way Data Binding
Similar to Knockout.js:
-
Keeps things DRY
-
Single source of truth
-
Multiple views connected to the same model
-
Alternate views (mobile, desktop) on single model
<input ng-model='user.name'>
$scope.user = { name: 'Hunter' };
Dependency Injection
Helps in several scenarios:
- Memory management
- Automated testing
- Code reuse
- Decoupled architecture
function Controller($scope, $http, $compile) ...
Extending HTML
"Directives" are possibly the most compelling part of Angular.
New elements:
<dtv-carousel>
<dtv-filterlist>
New attributes:
<span ng-pluralize>
When to use Angular
- Modularity and reuseable components is a goal
- Testing and maintainability is a priority
- Building a single-page application (SPA)
- Following an AJAX + API architecture
- Implementing non-trivial interactivity
- Designing a fluid, dynamic, app-like user experience
When not to use Angular
- Building a series of simple, traditional pages
- Designing for minimal interactivity
- Implementing with limited JavaScript resources
- Client-side rendering is unacceptable
