This article represents some of the key reasons why one would want to adopt or migrate to Ionic 2. I am doing for my apps soon. Read out the original announcement on this page. Please feel free to comment/suggest if I missed to mention one or more important points. Also, sorry for the typos.
- Significant Performance Improvements: Leverages Angular 2 thereby bringing significant performance boosts to the ionic apps. Additionally, some of the following improvements brought by Angular 2 will further boost the Ionic 2 adoption:
- Server-side rendering
- cross-platform views
- Web workers
- Improved Overall Navigation: The way ionic pages were navigated in past, especially, between standard and tabbed pages was cumbersome. They have brought significant improvements in that area. Further pages can be nested infinitely and one may not be required to associate a route to a particular page. That is a huge gain.
- Sidemenu Improvements: Gone are the days when one would require to search how to make sidemenu and tabbed pages work. While building an app, I faced this issue and searched the net to find solution. It was quite an effort. with Ionic 2, it would become easy to have multiple menus, navigate menu from anywhere in the app and also enable/disable menus as required.
- Support for Material Design: This one is my favorite from UI design perspective. I remember including material design module and disabling it later due to platform issues especially on iOS. With support for material design, one can achieve what they have called as Platform continuity
- Theming based on Sass: Creating custom themes has become very easy with the help of Sass. There are some common/shared variable along with specific variables for different platforms. By changing values of these variables, one could get different effect. This was difficult to achieve in Ionic 1.
- More Ionic Icons: Seems they have come up with a library of 900 icons. One of the coolest thing about ionic icons is the fact that the icons could change, depending on the platform from which the app is running.
- Build Tools: Each starter template comes up with following:
- Webpack for bundling and transpiling
- Sass for CSS compilation
- NPM for package management
