3.0.0.beta1 — Pre-release

on GitHub

Vaadin Flow 3.0.0.beta1 is a pre-release of Vaadin Flow 3.0.0

The major new feature in the Flow 3.x series is support for TypeScript views, and a new way to bootstrap the app based on index.html and index.ts files, without creating a server-side UI instance. The new way of bootstrapping required a breaking change to the bootstrapping APIs, whereas the support for TypeScript is compatible with the Flow 2.x series. The 3.x series has also removed a number of APIs deprecated in Flow 2.x.

• Support for TypeScript views and client-side routing (#6218)
• @Endpoint annotation to allow calling Java methods from TypeScript views in a type-safe way (#6229)
