I am not familiar with Node.js or npm at all, but my IT has told me node.js/npm is not compatible with our IIS, and the only search plugins to add on to leaflet are using npm to install them.
I did a search here and found this solution without npm - leaflet-control-geocoder, but it searches address databases such as google or bing, not the geojson data I have plugged into my map that I need to be able to search.
So my question is, is there a way to use the Leaflet Search plugin or leaflet-fusesearch plugin without using npm to install it?
