IONIC IN PRODUCTION ENVIRONMENT

„Code once run every where” Portability of code Cheaper development cost Simpler and cheaper maintenance. HTML – Javascript - CSS – jQuery

PURPOSE OF HYBRID ARCHITECUTRE

CORDOVA APP ARCHITECTURE

Application for airplain crew memebers. Geo positioning, Crew member checkin, monthly schedule, notifications for different

backend events, campaigns, refresh state machine logic. Duplex communication crew member - administration.

Super sexy look and feel Smooooth animations and transitions between screens Native app in JS + CSS3 way Application UI logic Support for Ios/Android/Web browsers

PROJECT DEMANDS

One of the top 5 American airline company18.000 employees, 6.000 crew membersFleet of 220 airplanesRevenue in 2014 cca 5.000 bil. $High demand customer

CUSTOMER

Huge angular js and ionic community among others open source platforms.

(EmberJS, BB + JQM, Onsen) or separate js libraries. Ionic monthly releases after alfe release + extra ionic services that help

you in development huge community support + extra libs: Ng – cordova Fast prototyping (Ionic gave us the best UI – results in prototyping phase)Kendo UI

WHY WE TAKE I+A IN 2015

Performance - solved Dirty watching Screen transitions, animations Dom rendering + caching

Compatibility for different device screen resolutionsCompatibility for different browsers. New components that are not in scope of ionic components /

according the design. Or someone from management / pilots.

PROBLEMS VOL. 1

Cordova plugins Doesn’t work as expected

New platform versions arrivingComplexity of Angulara 1.xMemory leaks

PROBLEMS VOL. 2

Duration – 7 months, 2 months extra over planed schedule. Ipad app on IOS-om 7.X 8.X 9.X in first production version – cca 10.000

lines of code. Extra app has being developed for recreating test use cases.15 people worked on project. Production without hot fixes – all bugs in production has being qualified

as low level risks and fixes were postponed for next production release. Management and customer was satisfied.

SUMMA SUMMARUM OF THE PROJECT

If you need to choose hybrid framework today with fixed end date in nearest future. Don’t choose Ionic platform which is in first beta release and unreliable at the moment for complex business apps.

Alternatives React mobile – FB library. Nativescript + Angular 2.0. Meteor Js + Angular 2.0

If you are in prototype phase and first run isn’t mission critical choose Ionic framework. Angular 2.0 is going to be a leader of JS frameworks in 2016.

LESSON LEARNED - 1

Hybrid development is never code once run everywhere, it is code once adopt everywhere, prepare your management for that.

If you are develop app for the customers define the app os versions and device sizes that are going to support in post production phase. My recommendation is that you choose last 2 major versions, believe me, your life is going to be easier.

Hire senior developers with experience in hybrid mobile development. Developers with HTML + JS + Jquery skills are out of scope for hybrid mobile job.

If you don’t know how to profile JS aps find someone who does, so you can mitigate the risks of app being refused in app store because of memory leaks.

Focus your development on IOS, Android and Web platforms only.
