10 Reasons to choose AngularJS

it`s like marriage...
Choosing a Framework
nirkaufman@gmail.com

You used to be in charge.
it`s going to change.
Inversion of control

First, let`s make it clear.
Framework vs Library

Library
A set of function that you call.
Each function does some work, and returns
the control back to you.
You Are in Charge.

Framework
Has a behaviour built in.
we plug-in into it, register our classes and the
framework code is calling our
code in a point in time.
You are not in charge.

“ The framework often plays the role of the main
program in coordinating and sequencing
application activity. This inversion of control
gives frameworks the power to serve as
extensible skeletons. The methods supplied by
the user tailor the generic algorithms defined in
the framework for a particular application. “
-- Ralph Johnson and Brian Foote

Let`s see what angularJS
Has to offer
Wear the architect Hat!

I want my application to be able to grow.
I want to add features painlessly.
Modularity

In angular, we can organized our code into
module objects which can depend on each other.
it`s make our code cleaner and modular.
Building blocks
we can add, replace, update
or even parallel develop
modules.

I want to write code that i can reuse.
I want to share components across projects.
Reusability

We can pack our code in modules and share
them across apps.
Angular components are just POJO`s, we can
use them in any javaScript project.
Reusable Components
which makes our
maintenance work
more efficient.

I want to understand what's going on in my
app just by reading the code.
Readability

Angular directives enable us to develop in a
declarative style that is very readable.
Because angular development is done in plain
javaScript, we can keep it clean and effective.
Declarative code style
Directives enable designers
to develop without
writing code.

I want to plug-in functionality into existing
project easily.
Embeddable

Thanks to the concept of root Scope, angular app
can run only in a limited section on the page.
3rd party libraries are welcome.
Play nice with others
We can wrap any 3rd party
library in a directive to keep
our loose coupling to the
view

I want me and my team to get started quickly
as possible.
Learning Curve

AngularJS embrace web standards, which we
already know..
● HTML - used for templates.
● CSS - used for Animations & other internal
work
● JavaScript - just plain javaScript. no need to
inherit from proprietary types. code can be
reused.
New technologies?

I want to perform tests with minimum effort
Testable

Angular designed to be testable.
Thanks to a good separation of logic from view,
and the dependency injection system,
code can be easily isolated for testing.
Testing is easy
Angular provides us ready
to use mocks to make it
even easier.

I want to add funcullity to the framework.
I want to replace parts of the components
with my own.
Extendable

AngularJS built on the concept of directives.
The angular team expose us the same API they
use to develop directives.
Give me your API!
Which means that we can
extend & replace core
directives easily.

Angular packed with a collection of core services.
we can use decorators to wrap them and add
custom features
What about services?
We can completely override
core services, or delegate to
them.

I want to choose my own folder structure.
I want to model my data my way.
Flexibility

Angular do not force us to a certain folder
structure.
Data models are not predefined.
there are no conventions restricts.
I'm the architect!
Which means that we have
the freedom to choose
what's fits us.

I want to meet and learn from people who
using the same framework.
Community

Not at all! angular is HOT.
Meetups, Forums, LinkedIn groups and much
more..
Are we alone?
google trends
angularjs-il
stackoverflow

And the community take advantage of this to
extend angular and create custom tools.
After all, it`s open-source
The ionic framework is a
great example:
http://ionicframework.com/

I want a variety of learning resources for me
and my team.
Resources

Angular documentation has become really
easy to read and understand so it`s a good
place to start.
Choose your media
But thats not all...

Dozens of books have already been written on
angularJS.
My top 3 AngularJS books:
● ng-book by Ari Lerner
● AngularJS Directives by Alex Vanston
● build your own angularJS by Tero Parviainen
AngularJS Books

Countless videos are out there..
My top 2 angularJS videos sites:
● codeschool - a complete free course
● egghead.io - 127 (and counting) angular lessons
AngularJS Videos

Endless online resources are
there just a click-away..
My top 2 angularJS online sources:
● ng-newsletter - delivered weekly
● ng-learn.org - angular news and more..
● angular blog - useful and contain great links
AngularJS On-line
