This project contains simple Angular 10 app with Nominatim API geocoding integration, plus Graphhopper. Also the project uses Firebase to save all distances between two addresses.
Run ng serve for a dev server.
Navigate to http://localhost:4200/.
Run ng build to build the project.
Look into RespuestasPreguntasSpike added to this repository.
I used a project called Angular-Leaflet as example to build this one. I tried to keep it simple.
Cheers.
