Leaflet4Vaadin provides a Java API for Leaflet, which is a popular map implementation.

With this Vaadin add-on you can use LeafletJS with java on server side.

If you want to contribute this add-on on github no hesitate just contact me.

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 supports
  • supports Leaflet plugins (eg.: fullscreen, heatmap, markercluster)

Future improvements

  • i18n supports
  • leaflet editable plugin integration
  • design and performance improvements
  • use Typescript on client-side instead of JS
  • supports parameters in custom events
  • bugfixes

Example usage

MapOptions options = new DefaultMapOptions();
options.setCenter(new LatLng(47.070121823, 19.204101562500004));
options.setZoom(7);
LeafletMap leafletMap = new LeafletMap(options );
leafletMap.setBaseUrl("https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png");
add(leafletMap);
