Improvements in Ionic v4 RC?
Ivy Renderer for Angular users
Ionic v4 will be shipped with Angular Ivy Renderer. It is Angular’s fastest and smallest renderer so far and will prove to be useful for Angular and Ionic developers. Interestingly, even a simple Ivy “Hello World” app reduces down to a size of 2.7kb.
UI Library Distribution
Ionic Neutronium has made improvements to the UI library. It features the use of standard Web APIs like custom elements that are capable of lazy-loading themselves on-demand. Now both Angular and Ionic can iterate and improve independently, and developers can take advantage of these improvements with fewer restrictions.
Support for Angular tooling
Angular CLI and Router both have become production ready with this release and are capable of native-style navigation required by Ionic apps. This release also comes with an added support for Angular schematics, so Angular developers can run ng add @ionic/ angular to add Ionic directly to their app.
Angular, React, and Vue
Ionic v4 RC allows users to continue using Ionic in their projects based on React or Vue. The goal behind this release was to decouple Ionic from any specific version of one single framework’s runtime and component model. Last month, Ionic community and Modus Create released the alpha version of @ionic/vue. @ionic/ react is in progress and is expected to release soon.
Major bug fixes
- The issues with scrollable options have been fixed.
- The Cordova browser error has been fixed.
- Fixes have been made to sibling router-outlets and router-outlet memory.
- There is an improvement in progress-bar as it looks better now.
- Issues with virtual-scroll have been fixed.
Many users are happy with this release and awaiting the final version in 2019. This might prove to be the perfect new year celebration for the developers as well as the Ionic team.
