An easier way to build web applications
You don't need to think about requests, responses, and other low-level web development concepts with Vaadin Flow.
Much like building a traditional desktop application, you compose the UI from components, connect it to a data source and react to user events. The UI runs on the JVM without the need to expose REST services or come up with other ways to move data to the browser.
Flow apps are rendered in the browser as standard HTML. They work in all modern browsers and devices, no plugins required.
@Route("hello-world")
public class HelloWorld extends VerticalLayout {
public HelloWorld() {
TextField name = new TextField("Name");
Paragraph greeting = new Paragraph("");
Button button = new Button("Greet", event -> {
greeting.setText("Hello " + name.getValue());
});
add(name, button, greeting);
}
}
UI components included
Vaadin comes with an extensive set of beautiful UI components, like form inputs, dialogs, data grids and visualizations. You can extend components and create compositions directly in your Java code. Everything is built on open web standards and runs on all modern browsers (without plugins).
Supports real-time collaboration
Collaboration Engine provides features that enable your users to work together, in real-time, directly within the app. Show active users, implement a chat and allow multiple people to work on the same views with just a few lines of code.
Automated UI testing
Implement and automate UI testing with Vaadin TestBench. User simulated test allows you to catch any regressions or compatibility issues with all the major browsers before your users do.
Visual UI building
Use Vaadin Designer to build UIs faster. The drag & drop functionality and external device preview feature enables you to quickly assemble a HTML template that you can implement for your Flow app.
