Ionic 2 Beta 8 has arrived! This release brings many bug fixes, some breaking API changes and even a few new highly requested components!
What’s New in Beta 8?
Popover has landed
A Popover is a dialog box that appears on top of the current page. It’s positioned relative to the element that was tapped to open it, or in the center of the view if no element was passed.
Popovers can be used for displaying all types of information, but they’re most commonly used for overflow actions that don’t fit in the navigation bar. Take a look at our Popover documentation, which includes different usage examples.
The Range is a slider that lets users select from an array of values by moving a slider knob along the slider bar or track. The Range component has one knob by default, but it can be customized to use two knobs with a
upper value. We’ve included a ton of properties that can be set to change the behavior of the Range, such as setting the number to step by, and adding a pin that displays the value while being dragged.
As with other v2 components, the Range comes with full platform continuity design for iOS, Android, and Windows versions. Make sure to check out the Range documentation for more information!
What’s Changed in Beta 8?
We’ve made some API changes in order to improve the framework and make it more compatible with other libraries. We’re hoping these changes will be the last major changes to the API. Let’s dig in.
Progressive Web App Support
The web is the future of apps: It runs everywhere, it’s the most widely known technology stack, and it powers a rapidly increasing number of apps. Progressive Web Apps give you the best of both worlds: cross-platform app store deployment on iOS, Android, and Windows, along with deployment to the mobile web with the same code!
We’ve started the process of optimizing Ionic 2 in specific ways that improve our support for Progressive Web Apps. Here’s the low down:
- Ionic’s custom decorators have been removed.
@Pageshould be replaced with
IonicApphas been renamed to
ionicBootstrapis required to bootstrap the app.
- Config is now the third parameter in
ionicBootstrap(rootComponent, providers, config).
prodModeis now a config option, enabling or disabling production mode.
Please see the changelog for a step-by-step guide to update your app.
Ionic Component Events
All Ionic component events have been renamed to start with
ion. This is to prevent the Ionic events from clashing with native HTML events. For a full list of the events changed, please see the changelog.
Ionic Lifecycle Events
All Ionic lifecycle events have been renamed from the
onPage prefix to an
ionView prefix. The following is a full list of the name changes.
So, What’s Next?
