How nhatpham12/simplemap works
SimpleMap is a browser map and driving-directions app. A user searches for a destination; the search component resolves it through OpenStreetMap’s Nominatim service and passes the selected coordinates to the map controller. The controller obtains the browser’s current location, requests a driving route from OSRM, and displays the route and destination on a Leaflet map with turn-by-turn details. The README is empty, so this view follows the sampled React source and does not infer additional capabilities.
