Agenda
1. Conception
2. Design
3. Implementation

Write once, run anywhere(Sun Microsystems)
Write almost once, run
somewhere(Reality)
Hybrid Mobile Applications With JS
• WebView: Apache Cordova
• “Native” ones: React Native, NativeScript.
6
Conception
Again JavaScript?!
1. You can write once and use it for all popular mobile platforms.
2. You can use it for desktop with minimal changes.
3. And oppositely, you can easily adapt your web application to mobile.
4. It’s a very fast way of prototyping
8
Are hybrid apps the silver bullet?
1. It’s always slower than the native app (but now mobiles are freaky powerful, so
it’s hard to notice)
2. Not so flexible

Conception
•Web App
•WebView
•Proxy Layer
•OS
10
Some ordinary app:
• Browser
• AJAX calls to server
• Persistent storage
• I/O
• Hardware interaction
• Mobile
• AJAX calls to server
• Persistent storage
• I/O
• Hardware interaction
11
Equality?
12
Differences
• Feature
• AJAX calls to server
• Persistent storage
• I/O
• Hardware interaction
• Difference
• Different security policies
• Different types of storage and it’s size
• Different API’s but the same interfaces
• Browser has access to less devices
13
Scaffolding

Cordova

Cordova
1. WebView
2. Proxy between native API’s and WebView

Angular 4
20
Angular 4 – Advantages
1. MVVM-like architecture out of the box
2. Modular by design. Components and flexible DI.
3. Powerful tooling
21
Angular 4 Modularity

24
App 2
Form Media Whatever

Ionic Framework
25
What is Ionic?
1. UI Framework to imitate mobile UI.
2. UI Framework on top of Angular
3. Components set.
4. Ecosystem (not free)

Not only CSS

HOW
WOULD
ACCESS

SYSTEM?!
HOW
WOULD
I ACCESS
CAMERA?!
HOW
WOULD
I USE
SENSORS?!
Ideal Scenario

Cordova Plugins + Ionic Plugins
1. Cordova Plugins are bridges between native API and WebView
2. Quality of those plugin is a controversial point
3. Ionic Plugins are de-facto angular wrappers for Cordova plugins
4. Cordova plugins are native. You can’t fix them with JS
37
Implementation
Ionic CLI
1. Generate a new project
2. Development environment out of the box
3. Build the app
4. Generate components, services, pipes and some other stuff
5. Ionic Pro Services
39
Creating a new app
$ ionic start [name]
Scaffolding
1. Creates basic project structure for JS
2. Prepares basic cordova configuration with standard plugins
3. Installs dependencies (npm install)
4. Creates several basic components
41
Run code with watcher in browser
$ ionic serve
Run Cordova
$ ionic cordova [whatever]
Do not forget to add platforms!
$ ionic cordova platform add android
$ ionic cordova platform add ios
Code Generation
1. Create components, modules, services, unit tests.
2. Generates declarations and dependencies
45
Please

Building
1. You are still required to have environment for building mobile apps
2. But you can use cloud deployment for that
47
Mobile Apps CI: Issues
48
1. Handle git flow
2. Deployment should happen for iOS and Android
3. Build should be published on the internal repository / TestFlight
