Nowadays I'm very busy, unfortunately, I have no enough time to enhance this awesome Vaadin add-on. But its source code is available on GitHub so you can contribute if you have a feature request. Currently, this addon may have a lot of bugs so I don't recommend using this in a production environment. Of course, if you create a pull request on GitHub I will merge and release it if you want. Thank you for your understanding.

Leaflet4Vaadin provides a Java API for Leaflet, which is a popular map implementation, similar to Google Maps. Leaflet is lightweight and shines on mobile devices. Also it has an extensive set of add-ons, of which many are available for Vaadin too. With this Vaadin add-on you can use LeafletJS with the server side Java you know best, and you can easily extend it or just implement your custom plugins and integrate them.

Core Features:

• map configuration
• interactive layers
• map and layer events
• markers
• tooltip and popup binding
• layer groups
• vector layers
• dark theme
• map controls (zoom, layers, scale)
• map state functions
• tile layers
• GeoJSON support
• supports Leaflet plugins (eg.: fullscreen, heatmap, markercluster)

Future improvements

• i18n support
• leaflet draw integration
• design and performance improvements
• use Typescript on client-side instead of JS
• supports parameters in custom events
• selenium ui tests
• more examples
• bugfixes
• documentation
