Add reverse geocoding

[ertejaspatel]

Any plan to add reverse geocoding functionality?

Yes, but I'm really short on time lately. This project definitely needs a second maintainer.

Hi Stephan

first of all, thank you for the plugin, it is really helpful.

Any feedback on the reverse geocoding option?

I was using axios to use a reverse geocoding in google maps.

// ES7 version
import axios from 'axios';
export const searchReverseLocation = async ({ latitude, longitude }) => {
    try {
        const response = await axios.get(
            `https://maps.googleapis.com/maps/api/geocode/json?latlng=
            ${latitude},${longitude}&key=${API_KEY}`
        );
        return response.data.results[0].formatted_address
    } catch (error) {
        console.error(error);
        return error.toString();
    }
}

I don't know for some providers. I don't have any billing account(except for open street map) for other services that I could test.

I have a solution supporting Nominatim, Bing, Google (Geocoding API Key) and MapBox. You can do this with the javascript fetch now. Just change the url to change providers. Aside from Nominatim (no key required), the required api keys are the same ones that would be provided to the leaflet-geosearch provider.

var url = 'https://nominatim.openstreetmap.org/reverse?format=json&lat=42.39330&lon=-82.17380&zoom=18&addressdetails=1';
//var url = 'https://dev.virtualearth.net/REST/v1/Locations/42.39330,-82.17380?o=json&key=' + bingKey;
//var url = 'https://maps.googleapis.com/maps/api/geocode/json?latlng=42.39330,-82.17380&key=' + googleKey;
//var url = 'https://api.mapbox.com/geocoding/v5/mapbox.places/-82.17380,42.39330.json?access_token=' + mapBoxKey; // (Notice long,lat)
var result = fetch(url)
.then(response => { 
    if(!response.ok){
        let err = new Error("HTTP status code: " + response.status);
        err.response = response;
        err.status = response.status;
        throw err;
    }
    return response.json();
})
.then(responseJson =>{
    console.log('Reverse Geocode Result', responseJson);
})
.catch(error => console.log('Reverse Geocode',error));
