Leaflet4Vaadin

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

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);
