-This example React application uses [react-leaflet](https://www.npmjs.com/package/react-leaflet) and [shpjs](https://www.npmjs.com/package/shpjs?activeTab=readme) npm packages to display a full-screen interactive map (like google maps, without geolocation, but for free) with a simple button to upload geospatial data files in zipped [shapefile (.shp) spatial data format](https://en.wikipedia.org/wiki/Shapefile). As a bonus, it shows a marker on the centre of the map, and displays the latitude/longitude of that marker. :P

The geospatial data are then displayed in an Overlay. At the moment, only a single Overlay is supported (cannot render multiple shapefiles). As a bonus, it shows a marker on the centre of the map, and displays the latitude/longitude of that marker. :P
 
 Supports 30+ free [Tile Layers](https://wiki.openstreetmap.org/wiki/Tile_servers), i.e. OpenStreetMap, Stamen, ESRI, Stadia, USGI, etc. 
 Actually, the app includes an adapted copy of the [Leaflet-providers](https://github.com/leaflet-extras/leaflet-providers) configurations for various tiles providers. Fork it and edit the lib/TileProviders.js file to add your API keys, if you want to use one of the non-free tile providers (api key support not tested, though, you may have to hack it).
