The next
version of Google’s massively popular MV* framework
AngularJS has emerged
one of the most popular open source JavaScript frameworks in the arena of web
application development which places equal importance on application testing
and application writing, during simplifying the development process.
Why Angular 2.0?
1. Mobile
The new Angular
version will be only focused on the mobile apps development.
2. Modular
Several modules will
be removed from Angular’s core, concluding in better performance. “Pick and
choose the parts you need.”
3. Modern
Angular 2.0 will
target ES6 and “evergreen” modern browsers (those automatically updated to the
latest version).
4. Routing Solution
The router in Angular
2.0 has been redeveloped to be simple, yet extensible. It will include the
following basic features:
- Simple JSON-based Route Config
- Optional Convention over Configuration
- Static, Parameterized and Splat Route Patterns
- URL Resolver
- Query String Support
- Use Push State or Hashchange
- Navigation Model (For Generating a Navigation UI)
- Document Title Updates
- 404 Route Handling
- Location Service
- History Manipulation
Uniqueness:-
1. Module loader
Angular 2 utilizes the
standard System.js which is a universal module loader that loads ES6
modules, AMD, Common JS…With help of this module loader, we just need to import
the file where we bootstrap our app, and we are good to go…
Components
So a component is a directive having a template and
that is what we use to represent a page in Angular 2. A component is
simply a class. Get rid of scopes.
3. Directives
Directives in Angular 2 are
found much simpler and straightforward.
4. $apply()
In Angular 2 we are
using the built-in setTimeout for changing our message. Of
course it works. No more fear while mixing Angular with “non angular” stuff.
5. Events
Angular 2 introduces a
new syntax for this events, also called statements:
6. References
Angular 2 allows us to
create a reference to a particular node which will be local to the template.
7. Services
A service in Angular 2
is simply a…Class! Angular 2 has a service for http.
8. Overpowered outlets
Angular 2, we can get
the new router router-outlet and extend it, yes, literally. No more
weird $decorators.
Angular 2 is the must
needed right step forward. Way simpler than Angular 1. Cut away controllers,
scope inheritance, the directives API is easy to understand than the
actual. No more $apply, and the best of all things, thanks to [properties] and
(events) we removed like 30 needless directives and apart from that, we
simplified the way of consuming directives.
