Tools

Getting Started with Vaadin

App starters

The best way to get started with Vaadin is to go to https://start.vaadin.com and configure your new application by setting up your views, entities, styles, and the technology stack you’re interested in.

Note

Vaadin 22 starters are not available just yet in vaadin.com. You can use Vaadin 21 starter and manually change Vaadin version (see instructions below).

Maven Archetypes

Maven is the de-facto build tool for Java web applications. Major IDEs also support Maven out of the box and most often you'll be using Maven via your favorite IDE.
There are currently two Maven archetypes available, the vaadin-archetype-application which corresponds to the project base for Flow and the corresponding vaadin-archetype-spring-application if you prefer use Flow with Spring.
The version of the archetype should match the platform version. After you have Maven installed, you can quickly create and run a Vaadin app with the following command: 

mvn -B archetype:generate \
                -DarchetypeGroupId=com.vaadin \
                -DarchetypeArtifactId=vaadin-archetype-application \
                -DarchetypeVersion=22.2.0\
                -DgroupId=org.test \
                -DartifactId=vaadin-app \
                -Dversion=1.0-SNAPSHOT \
                && cd vaadin-app \
                && mvn package jetty:run

mvn -B archetype:generate \
                -DarchetypeGroupId=com.vaadin \
                -DarchetypeArtifactId=vaadin-archetype-spring-application \
                -DarchetypeVersion=22.2.0\
                -DgroupId=org.test \
                -DartifactId=vaadin-app \
                -Dversion=1.0-SNAPSHOT \
                && cd vaadin-app \
                && mvn

Manually changing Vaadin version for Java projects

Known Issues and Limitations

Flow

  • The Template-in-Template feature has some limitations
  • Links matching the context do not result in browser page load by default, instead they are handled with application routing. To opt-out, set the router-ignore attribute on the anchor element. This opt-out is needed for cases when native browser navigation is necessary, e. g., when using Anchor to link a StreamResource download.

OSGi support
