geocoding services for react native

Download

Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.devfd:react-native-geocoder:'
	}

	dependencies {
		implementation("com.github.devfd:react-native-geocoder:")
	}

	<dependency>
	    <groupId>com.github.devfd</groupId>
	    <artifactId>react-native-geocoder</artifactId>
	    <version></version>
	</dependency>


                            
    libraryDependencies += "com.github.devfd" % "react-native-geocoder" % ""


                            
    :dependencies [[com.github.devfd/react-native-geocoder ""]]

Readme

react-native-geocoder

geocoding services for react native

Version table

| Geocoder Version | RN | | ------- |:----------| | >=0.5.0 | >= 0.47.0 | | >=0.4.6 | >= 0.40.0 | | <0.4.5 | <0.40.0 |

Install

npm install --save react-native-geocoder

iOS

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

Android

In android/setting.gradle

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

In android/app/build.gradle

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

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';

// 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.
