What is Envas

Envas is a Java software framework that is designed to support the development of modern Niagara web applications and widgets without coding HTML, CSS and JavaScript. Envas takes care of much of the hassle of Web development, so you can focus on writing your code in Java.

Envas relies on the open source project Vaadin. Visit the Vaadin web site and check out the sampler. You will find many examples there, including source code. Good news! Everything, that you will see there, you can do in Niagara. And much more. Envas has a lot of addons making the Niagara integration easy. With Envas you will get data binding, subscribers and listeners, a message bus, Baja field editors, charts, etc.
