Vaadin Examples

A repository with examples based on Vaadin Flow 14 and the simple Beverage Buddy app.

Initial aim is to provide a good example of D3js integration where backing data from the Vaadin application is loaded via a separate servlet. Other examples are welcome.

Characteristics

• Based on Vaadin 14 and Spring Boot
• Uses JAR-based packaging, so static resources (images, JavaScript files) are in src/main/resources/META-INF/resources/frontend
• The property file is filtered, see the Maven pom.xml and src/main/resources/env/application.dev.properties, etc.
• Internationalization supports UTF-8-based resource files

To get started

• To build: mvn package
• To run: mvn spring-boot:run
• Open a browser to http://localhost:8081/app

Backlog / issues for the D3 Tree example

• Drag/Move events are not available under Vaadin, see this post.
• The proper node/item for JavaScript click results should be available in Java
• Nodes should be colorable from Java
• other

Other examples to be added

• tbd
