react-native-geocoding

A geocoding module for React Native to transform a description of a location (i.e. street address, town name, etc.) into geographic coordinates (i.e. latitude and longitude) and vice versa.

This module uses Google Maps Geocoding API and requires an API key for purposes of quota management. Please check this link out to obtain your API key.

Install

npm install --save react-native-geocoding

Example

import Geocoder from 'react-native-geocoding';

// Initialize the module (needs to be done only once)
Geocoder.init("xxxxxxxxxxxxxxxxxxxxxxxxx"); // use a valid API key
// With more options
// Geocoder.init("xxxxxxxxxxxxxxxxxxxxxxxxx", {language : "en"}); // set the language

// Search by address
Geocoder.from("Colosseum")
		.then(json => {
			var location = json.results[0].geometry.location;
			console.log(location);
		})
		.catch(error => console.warn(error));

// Search by address, with a biased geo-bounds
Geocoder.from("Pyramid", {
		southwest: {lat: 36.05, lng: -115.25},
		northeast: {lat: 36.16, lng: -115.10}})
		.then(json => {
			var location = json.results[0].geometry.location;
			console.log(location);
		})
		.catch(error => console.warn(error));

// Search by geo-location (reverse geo-code)
Geocoder.from(41.89, 12.49)
		.then(json => {
        		var addressComponent = json.results[0].address_components[0];
			console.log(addressComponent);
		})
		.catch(error => console.warn(error));

// Works as well :
// ------------

// location object
Geocoder.from({
	latitude : 41.89,
	longitude : 12.49
});

// latlng object
Geocoder.from({
	lat : 41.89,
	lng : 12.49
});

// array
Geocoder.from([41.89, 12.49]);
