DESCRIPTION
In recent years, a modern approach for building client-centric applications, Single-Page Web Applications, has become well-known in our developer community. As a result, there are several new frameworks that have made their way to the professional developer’s landscape. AngularJS is a new framework that radically changes the way developers build a web application. It is one of the most ideal alternatives that offers a powerful foundation to build your web application. This slides is dedicated to developers who want to learn the best practices in single-page approaches and how to apply them with AngularJS.

IS SPA THE FUTURE OF WEB APP ?
(one of) SPA pitfall: content-heavy sites
SPA BENEFITS
Runs faster Gives better UX Is able to operate offline (thanks to HTML5) Uses less network bandwidth
SPA DRAWBACKS

serviceDirectives & Filters
USE (INJECT) BUILT-IN SERVICES
Use HTTP and Cookie built-in services
DEPENDENCY INJECTION IN NUTSHELL
Dependency is handed to the component
AngularJS Injector service
ANGULARJS INJECTOR SERVICE
Injector is responsible for creating two types of objects: User-defined Objects: – We register a “recipe” to instruct Injector in how
to create objects– Recipe types: Value, Factory, Service, Provider
and Constant Specialized Objects: Controllers, Directives,
Filters and Animations
INJECT DEPENDENCY IN ANGULARJS
Elements to have dependencies: - Controller, Directive, Filter and Animation- Factory, Service and Provider
Elements can be injected (recipe): Service, Provider, Value, Factory and Constant

DIRECTIVES
are markers on a DOM element (an attribute or an element name)
attach behaviors to that DOM element and/or transform the DOM element (and its children)
DIRECTIVES
Template
Compiled view
FILTERS
“format the value of an expression for display to the user”
