      waypoints: [
       ...
      ],
      language: 'fr',
      showAlternatives: true,
      routeWhileDragging: true,
      reverseWaypoints: true,
      routeDragInterval: 0,
      autoRoute: true,
      **geocoder: L.Control.Geocoder.nominatim(),**
      
      altLineOptions: {
        styles: [
          {color: 'black', opacity: 0.1, weight: 11},
          {color: 'white', opacity: 0.25, weight: 9},
          {color: 'blue', opacity: 0.25, weight: 3}
        ]
      },
      lineOptions: {
        styles: [
          {color: 'black', opacity: 0.3, weight: 11},
          {color: 'white', opacity: 0.9, weight: 9},
          {color: 'red', opacity: 1, weight: 3}
        ]
      },
        }
      }
    }).addTo(map);
