Location Monitor is a very simple plugin which runs in the background to monitor location changes such as network and/or geolocation changes.

Installing the plugin

$ npm install react-native-location-monitor --save

Installing the dependencies

react-native-location-monitor uses the two dependencies below.

react-native-background-fetch

$ npm install react-native-background-fetch --save

• iOS Setup
• Android Setup

react-native-network-info

$ npm install react-native-network-info --save
$ react-native link

Config

Common Options

@param {Integer} minimumFetchInterval [15]

The minimum interval in minutes to execute background fetch events. Defaults to 15 minutes. Note: Background-fetch events will never occur at a frequency higher than every 15 minutes. Apple uses a secret algorithm to adjust the frequency of fetch events, presumably based upon usage patterns of the app. Fetch events can occur less often than your configured minimumFetchInterval.

Android Options

@config {Boolean} stopOnTerminate [true]

Set false to continue background-fetch events after user terminates the app. Default to true.

@config {Boolean} startOnBoot [false]

Set true to initiate background-fetch events when the device is rebooted. Defaults to false.

:exclamation: NOTE: startOnBoot requires stopOnTerminate: false.

Usage Example

import {LocationMonitor} from "react-native-location-monitor";

export default class App extends Component {
    constructor(props) {
        super(props);
        let params = { minimumFetchInterval: 15,
                        stopOnTerminate: false,
                        startOnBoot: true };
        let locationMonitorConfig = LocationMonitor.createConfiguration(params);
        LocationMonitor.configure(locationMonitorConfig);
    }
    
    componentDidMount() {
        LocationMonitor.start(
            location => console.log(JSON.stringify(location)),
            err => console.error(err))
            .then(status => {
                switch (status) {
                    case LocationMonitor.Status.READY:
                        console.log("started");
                        break;
                    case LocationMonitor.Status.BACKGROUND_FETCH_DENIED:
                    case LocationMonitor.Status.BACKGROUND_FETCH_RESTRICTED:
                        console.error("did not start");
                        break;
                }});
    }
}
