What is Ionic? Ionic makes it easy to build high-performance mobile and Progressive Web Apps (or PWAs) that look and feel beautiful on any platform or device. You can think of Ionic as the front-end UI framework that handles all of the looks and feels and UI interactions your app needs in order to be compelling.

3. Hybrid
Application
3
A hybrid application (hybrid app) is one that combines
elements of both native and Web applications. It built
with Javascript, HTML, and CSS and run in something
called Webview, a simplified browser within your app.
Benefits of using Hybrid application:
● One codebase to manage
● save time and money
● Easier to scale
● Provide Offline support

6. IONIC
Framework
6
The dev-friendly app platform for building cross-
platform apps with one codebase, for any device,
with the web.
What is Ionic?
Ionic makes it easy to build high-performance mobile and Progressive
Web Apps (or PWAs) that look and feel beautiful on any platform or
device. You can think of Ionic as the front-end UI framework that
handles all of the look and feel and UI interactions your app needs in
order to be compelling.

7. What’s New in
Ionic 3
7
● Angular 4.0.0
The upgraded Ionic framework is compatible with Angular 4. This
introduces new updated features, support the new version of
typescript, fast and small applications and many more.
● TypeScript 2.1 and 2.2 compatibility
Typescript acquires all the classes of javascript and therefore
known as the superset of javascript. Ionic works with the latest
version of Typescript same like Angular framework.

8. What’s New in
Ionic 3
8
● IonicPage Decorator
You can set up deep links into your application using IonicPage
Decorator. This allows an easy way to set up lazy loading in your
application and customize the configuration of each and every
individual page.
● Lazy loading
Ionic 3.0 includes support for lazy loading.The changes affect the
file structure and navigation of your application, but they will
ultimately speed the application up.

9. Benefits of
Ionic 3
9
● Platform Independent Framework
● Cross-Platform Mobile App Development
● Default User Interface
● Based on Angular
● Utilizes Cordova Plugins

Navigation
14
● It’s a simple stack
● PUSH new pages to go forward
● POP the top page off to go backward
● SETROOT to navigate back to the home page.
● Navigation using Lazy loading.

● Platform Specific styles
● Responsive Grids
● Sass Variables
● Theming your Ionic App
● IonIcons

16. Platform
Specific Styles
16
Ionic uses modes to customize the look of
components. Each platform has a default mode, but
this can be overridden. For example, an app being
viewed on an Android platform will use the md
(Material Design) mode.
Usage
<ion-app class="md">
<ion-app class="ios">
<ion-app class="wp">

17. Responsive
Grids
17
It is heavily influenced by Bootstrap’s grid system.The
grid is composed of three units — a grid, row(s) and
column(s). Columns will expand to fill their row, and will
resize to fit additional columns. It is based on a 12
column layout with different breakpoints based on the
screen size.
<ion-grid>
<ion-row>
<ion-col>
1 of 3
</ion-col>
<ion-col>
2 of 3
</ion-col></ion-row>
</ion-grid>

18. Sass Variables
18
Sass Variables allow you to define a value once and
use it in multiple places. Variables begin with dollar
signs and are set like CSS properties.
Example:
$control-height: 40px;
Usage:
let’s assign $control-height to the height attribute of two
selectors:
.header {
height: $control-height;
}

19. Theming your
app
19
Theme support is baked right into Ionic apps. Changing
the theme is as easy as updating the $colors map in
your src/theme/variables.scss file:
$colors: (
primary: #488aff,
secondary: #32db64,
danger: #f53d3d,
light: #f4f4f4,
dark: #222
);

20. Cordova
plugins
20
Cordova is a project that provides web access to native plugins. They
allow your app to use native device capabilities beyond what is
available to pure web apps. Using Cordova plugins you app can have
access to Battery, Camera, Dialogs, Geolocation, and more…
It is very easy to manage cordova with ionic:
$ ionic cordova plugin
Synopsis
$ ionic cordova plugin [<action>] [<plugin>]

21. Cordova
plugins
Description
21
Input Description
action

$ ionic cordova plugin add cordova-plugin-inappbrowser@latest
$ ionic cordova plugin rm cordova-plugin-camera

22. Quick Start
