Vaadin Flow 1.5.0.alpha4 is a prerelease of Vaadin Flow 1.5.0

Vaadin Flow 1.5.0.alpha4

Flow is a new Java web framework for creating UIs using Java or HTML. Flow handles everything related to communication between client and server and makes it possible to create UIs using the desired abstraction level you choose. It has all the capabilities you need to build a modern web app: from high level APIs for structuring your applications and binding data to it, into taking full control over the DOM and communication with HTML templates.

Flow is a part of the Vaadin platform. For information and helpful resources like documentation and examples on Vaadin Flow, please visit the Flow page vaadin.com/flow.
