geocoding services for react native

Install

npm i react-native-geocoder-mrousavy
cd ios; pod install; cd ..

Usage

import Geocoder from 'react-native-geocoder-mrousavy';

// Position Geocoding
var NY = {
  lat: 40.7809261,
  lng: -73.9637594
};

Geocoder.geocodePosition(NY).then(res => {
    // res is an Array of geocoding object (see below)
})
.catch(err => console.log(err))

// Address Geocoding
Geocoder.geocodeAddress('New York').then(res => {
    // res is an Array of geocoding object (see below)
})
.catch(err => console.log(err))

Fallback to google maps geocoding

Geocoding services might not be included in some Android devices (Kindle, some 4.1 devices, non-google devices). For those special cases the lib can fallback to the online google maps geocoding service

import Geocoder from 'react-native-geocoder';
// simply add your google key
Geocoder.fallbackToGoogle(MY_KEY);
 
// use the lib as usual
let ret = await Geocoder.geocodePosition({lat, lng})
// you get the same results
 

With async / await

try {

    const res = await Geocoder.geocodePosition(NY);
    ...

    const res = await Geocoder.geocodeAddress('London');
    ...
}
catch(err) {
    console.log(err);
}

Geocoding object format

both iOS and Android will return the following object:

{
    position: {lat, lng},
    formattedAddress: String, // the full address
    feature: String | null, // ex Yosemite Park, Eiffel Tower
    streetNumber: String | null,
    streetName: String | null,
    postalCode: String | null,
    locality: String | null, // city name
    country: String,
    countryCode: String
    adminArea: String | null
    subAdminArea: String | null,
    subLocality: String | null
}

Notes

iOS

iOS does not allow sending multiple geocoding requests simultaneously, hence if you send a second call, the first one will be cancelled.

Android

geocoding may not work on older android devices (4.1) and will not work if Google play services are not available.
