React-Native Get Location

⚛ Simple to use React Native library to get native device location for Android and iOS.

Requirements

• React Native >= 0.60.0
• iOS >= 9.0

Install

Install dependency package

yarn add react-native-get-location

Or

npm i -S react-native-get-location

Go to the folder your-project/ios and run pod install, and you're done.

Android post install

For Android you need to define the location permissions on AndroidManifest.xml.

<!-- Define ACCESS_FINE_LOCATION if you will use enableHighAccuracy=true  -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

<!-- Define ACCESS_COARSE_LOCATION if you will use enableHighAccuracy=false  -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

iOS post install

You need to define the permission NSLocationWhenInUseUsageDescription on Info.plist.

<key>NSLocationWhenInUseUsageDescription</key>
<string>This app needs to get your location...</string>

Usage

There is only one function that you need to use to get the user's current location.

import GetLocation from 'react-native-get-location'

GetLocation.getCurrentPosition({
    enableHighAccuracy: true,
    timeout: 60000,
})
.then(location => {
    console.log(location);
})
.catch(error => {
    const { code, message } = error;
    console.warn(code, message);
})

For more details, see the Sample Project.
