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
