How can I get city name from a latitude and longitude point?

Here is the latest sample of Google's geocode Web Service

https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&key=YOUR_API_KEY

Simply change the YOUR_API_KEY to the API key you get from Google Geocoding API

P/S: Geocoding API is under Places NOT Maps ;)

BigDataCloud also has a nice API for this, also for nodejs users.

they have API for client - free. But also for backend, using API_KEY (free according to quota).

Their GitHub page.

the code looks like:

const client = require('@bigdatacloudapi/client')(API_KEY);

async foo() {
    ...
    const location: string = await client.getReverseGeocode({
          latitude:'32.101786566878445', 
          longitude: '34.858965073072056'
    });
}

In case if you don't want to use google geocoding API than you can refer to few other Free APIs for the development purpose. for example i used [mapquest] API in order to get the location name.

you can fetch location name easily by implementing this following function

 const fetchLocationName = async (lat,lng) => {
    await fetch(
      'https://www.mapquestapi.com/geocoding/v1/reverse?key=API-Key&location='+lat+'%2C'+lng+'&outFormat=json&thumbMaps=false',
    )
      .then((response) => response.json())
      .then((responseJson) => {
        console.log(
          'ADDRESS GEOCODE is BACK!! => ' + JSON.stringify(responseJson),
        );
      });
  };

Following Code Works Fine For Me to Get City, state, country, zipcode (Using Google Map Geo API) :

 var url = "https://maps.googleapis.com/maps/api/geocode/json?latlng="+lat+","+long+"&key=KEY_HERE&sensor=false";
        $.get(url, function(data) {
        var results = data.results;
            if (data.status === 'OK') 
            {
                //console.log(JSON.stringify(results));
                if (results[0]) 
                {
                    var city = "";
                    var state = "";
                    var country = "";
                    var zipcode = "";
                    
                   var address_components = results[0].address_components;
                    
                    for (var i = 0; i < address_components.length; i++) 
                    {
                       if (address_components[i].types[0] === "administrative_area_level_1" && address_components[i].types[1] === "political") {
                            state = address_components[i].long_name;    
                        }
                        if (address_components[i].types[0] === "locality" && address_components[i].types[1] === "political" ) {                                
                            city = address_components[i].long_name;   
                        }
                        
                        if (address_components[i].types[0] === "postal_code" && zipcode == "") {
                            zipcode = address_components[i].long_name;

                        }
                        
                        if (address_components[i].types[0] === "country") {
                            country = address_components[i].long_name;

                        }
                    }
                  var address = {
                        "city": city,
                        "state": state,
                        "country": country,
                        "zipcode": zipcode,
                  };
                  console.log(address);
               } 
               else 
               {
                   window.alert('No results found');
               }
            } 
            else 
            {
                window.alert('Geocoder failed due to: ' + status);
            
            }
        });

There are many tools available

1. google maps API as like all had written
2. use this data "https://simplemaps.com/data/world-cities" download free version and convert excel to JSON with some online converter like "http://beautifytools.com/excel-to-json-converter.php"
3. use IP address which is not good because using IP address of someone may not good users think that you can hack them.

other free and paid tools are available also

you can do it with pure php and google geocode api
