react-native-geocoder-reborn

Geocoding services for react native.

The project is built on top of devfd/react-native-geocoder, due to original project is not likely being maintained. This fork should be a drop-in replacement. Some bug fixing and TypeScript support have being added.

Version table

| Geocoder Version | RN | |--|--| | >=0.7.0 | >= 0.56.0 |

If you're using an older version of react-native, please consider using devfd/react-native-geocoder instead.

Install

yarn add react-native-geocoder-reborn

or

npm install --save react-native-geocoder-reborn

Link

Autolinking with react-native-cli (requires react-native 0.60 or above)

cd ios && pod install && cd .. # CocoaPods on iOS needs this extra step
# run with react-native-cli
react-native run-ios
react-native run-android

Please review autolinking docs for detials.

If "Autolinking" is not available for you, please try the following:

react-native link react-native-geocoder-reborn

iOS

1. In the XCode's "Project navigator", right click on Libraries folder under your project ➜ Add Files to <...>
2. Go to node_modules ➜ react-native-geocoder-reborn and add ios/RNGeocoder.xcodeproj file
3. Add libRNGeocoder.a to "Build Phases" -> "Link Binary With Libraries"

Android

1. In android/setting.gradle add:

...
include ':react-native-geocoder-reborn', ':app'
project(':react-native-geocoder-reborn').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-geocoder-reborn/android')

3. In android/app/build.gradle

...
dependencies {
    ...
    implementation project(':react-native-geocoder-reborn')
}

4. register module (in MainApplication.java)

import com.devfd.RNGeocoder.RNGeocoderPackage; // <--- import

public class MainActivity extends ReactActivity {
  ......
  @Override
  protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
            new MainReactPackage(),
            new RNGeocoderPackage()     // <------ add this
        ); 
  }
  ......
}

Usage

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

// 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-reborn';
// simply add your google maps key
Geocoder.fallbackToGoogle(YOUR_API_KEY);
// Add next line if you also want to use Google Maps api on iOS.
Geocode.forceGoogleOnIos(true);

// use the lib as usual
let res = await Geocoder.geocodePosition({lat, lng})
// you get the same results

With language preference

import Geocoder from 'react-native-geocoder-reborn';
// Set language attribute before api calls.
Geocoder.setLanguage('fr'); // Set language to French.

let res = await Geocoder.geocodePosition({lat, lng});

Note: Platforms may have different implantations for locale preference. Here is Google Maps API supported language list.

With async / await

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

try {
    ...
    await Geocoder.geocodePosition({ lat, lng });
    ...
    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
}

Known Issues

iOS

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