Today, I’m thrilled to announce the beta release of the best version of Ionic Framework yet: Ionic 4.0.0-beta.0! 🎉
Representing over a year’s worth of work, Ionic 4 brings significant performance and build time improvements, powerful theming capabilities, multi-framework compatibility, brand new documentation, and so much more to the Framework you know and love. And, despite all of the new improvements, transitioning to Ionic 4 is our easiest upgrade process yet!
Ionic 4 marks the first version of the Framework to completely embrace modern Web APIs such as Custom Elements, CSS Variables and Shadow DOM. And it’s completely framework-agnostic at the core, fulfilling our original mission to be, first and foremost, a UI library for web developers no matter what frontend tools or frameworks they decide to use.
At the same time, Ionic 4 continues to solidify its roots as Angular’s leading mobile solution. And we’re taking it even further by adopting new Angular tooling and features, ensuring that Ionic apps follow Angular standards and conventions, and benefit immediately from new Angular features the community has to offer.
There’s just so much awesome stuff to unpack with Ionic 4, but keep in mind Ionic 4 is in beta! Read on to learn more about the technology, how to migrate your existing ionic-angular apps if you’re feeling brave, and how to get started testing. We are working hard on the final release and your help will be huge for us getting there as soon as possible.
We’d also like to extend a huge THANK YOU to everyone that helped test the previous v4 alpha releases. Your input and feedback was instrumental in getting to this point. 💙
