Overview

"So you want to build a native app?"

More Platforms.  More Problems.

Why are we still coding for multiple platforms?

The Downsides of Native

  • Proficiency in each platform required

  • Entirely separate code bases

  • Timely & expensive development

  • Diminishing returns

"Is there an alternative?"

  • Hybrid Apps: Html 5 that acts like native
  • Phonegap renamed to Cordova
  • Web wrapped in native layer
  • Direct access to native APIs
  • Familiar web dev environment
  • Develop a single code base (web platform)

"Hybrid apps are slow!"

"The Times They Are a-Changin"

Mobile devices have rapidly improved!

Year Device Processor RAM
2007 iPhone 620 MHz 128 MB
2010 iPhone 4 1 GHz 512 MB
2015 iPhone 6 1.4 GHz dual-core 1 GB

Native SDKs Are Great

  • Common UI

  • Views

  • Navigation and stack history

  • Transitions

  • Gestures

There's No Web SDK

  • It's the wild-west for hybrid apps

  • We need to bridge the gap between web and native

  • We need rich, native-style UI components and interactions

  • We need UI APIs, not just jQuery widgets
