Native GPS location support for React Native.


Three installation methods are provided here for compatibility and ease of use. All of them require installing the package using NPM. However, you can install the iOS specific bits using one of three methods: RNPM, React-Native Link (only v0.28), or manual linking in XCode.

First step for all three is NPM Install to your project:

npm install --save react-native-location

RNPM Installation

For RNPM, first install RNPM globally and then simply run it with the 'link' command at the root of your project:

npm install rnpm -g
rnpm link

React-Native Link Installation

Since version 0.28 of React Native, rnpm has been merged into the codebase. So, as long as you are using the latest version of the CLI, then you can simply run link:

react-native link

Manual Installation

Finally, you can do a manual installation with XCode. Drag ios/RNLocation.xcodeproj from the node_modules/react-native-location folder into your XCode project. Click on the your project in XCode, goto Build Phases then Link Binary With Libraries and add libRNLocation.a and CoreLocation.framework.

NOTE: Make sure you don't have the RNLocation project open separately in XCode otherwise it won't work.

Example application

In the example folder is a React Native sample app which simply allows you to test out whether the library is working for you. You can also use this as a sample implementation to start from. The app requests always on permissions, takes reading every 5 distance and starts immediately. To utilize in the simulator, look on the Debug -> Location menu for optional sample trips that will show you updating location such as City Bicicle Ride, City Run and Freeway Drive.

Example App

PList Permissions

In order to use permissions, your enclosing app needs to grant permissions in the info.plist file. React Native automatically sets up the PList config key for NSLocationWhenInUseUsageDescription. However, to use NSLocationAlwaysUsageDescription you will need to add that in your PList file. The string message in the key will show in the Alert box when your app requests permissions. To start, you can simply add these to your file and edit them (or remove them) later. Remember to only request the permissions you NEED within your app. See the detail on Background Mode later on.

<string>This is the plist item for NSLocationWhenInUseUsageDescription</string>
<string>This is the plist item for NSLocationAlwaysUsageDescription</string>

Location Usage

var React = require('react-native');
var { DeviceEventEmitter } = React;

var { RNLocation: Location } = require('NativeModules');


var subscription = DeviceEventEmitter.addListener(
    (location) => {
        /* Example location returned
          coords: {
            speed: -1,
            longitude: -0.1337,
            latitude: 51.50998,
            accuracy: 5,
            heading: -1,
            altitude: 0,
            altitudeAccuracy: -1
          timestamp: 1446007304457.029

Heading Usage

var React = require('react-native');
var { DeviceEventEmitter } = React;

var { RNLocation: Location } = require('NativeModules');

    (data) => {
        /* Example data returned
          heading: 57.2839832

It is recommended to set NSWhenInUseUsageDescription in your Info.plist file.

Background mode

For background mode to work, a few things need to be configured:

  1. In the Xcode project, go to Capabilities, switch on "Background Modes" and check "Location updates".

  2. Using requestAlwaysAuthorization in place of requestWhenInUseAuthorization, like this:

  3. Set NSLocationAlwaysUsageDescription in your Info.plist file.

  4. For iOS9, set allowsBackgroundLocationUpdates to true, like this:



To access the methods, you need import the react-native-location module. This is done through var Location = require('react-native-location').



This method should be called before anything else. It requests location updates while the application is open. If the application is in the background, you will not get location updates. Either this method or Location.requestAlwaysAuthorization (but not both) needs to be called to receive updates.



This method should be called before anything else is called. It requests location updates while the application is open or in the background. Either this method or Location.requestWhenInUseAuthorization (but not both) needs to be called to receive updates.


Location.getAuthorizationStatus(function(authorization) {
  // authorization is a string which is either "authorizedAlways",
  // "authorizedWhenInUse", "denied", "notDetermined" or "restricted"

This methods gets the current authorization status. While this methods provides a callback, it is not executed asynchronously. The values authorizedAlways and authorizedWhenInUse correspond to the methods requestWhenInUseAuthorization and requestAlwaysAuthorization respectively.



Set the desired accuracy of location updates in meters. Determines the method used to obtain location updates. Low values will trigger using GPS.



Set the desired minimum distance between location updates in meters.




var subscription = DeviceEventEmitter.addListener(
    (location) => {
        // do something with the location

Start location updates. Your application will be called back with location updates that meet any mininum distance requirements that you specify via the DeviceEventEmitter event 'locationUpdated'.


var subscription = DeviceEventEmitter.addListener(
    (data) => {
        // do something with the heading

Start heading updates. Your application will be called back with heading updates.



Stop receiving location events.



Stop receiving heading events.



Stop receiving sigificant location change events.


To listen to events we need to call DeviceEventEmitter.addListener (var {DeviceEventEmitter} = require('react-native')) where the first parameter is the event we want to listen to and the second is a callback function that will be called once the event is triggered.


Received when a location update has been sensed by the system. The event delivers one parameter, location, that is an object with location, elevation, and accuracy data.


Received when the heading changes. The event delivers one parameter: an object with the current heading in degrees.
