React-Native Get Location

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

Requirements

• React Native >= 0.45.0
• iOS >= 8.0

Install

1. Install dependency package

   yarn add react-native-get-location

   Or

   npm i -S react-native-get-location

2. Link the native project

   react-native link react-native-get-location

Android post install

For Android API < 23 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: 15000,
})
.then(location => {
    console.log(location);
})
.catch(error => {
    const { code, message } = error;
    console.warn(code, message);
})

For more details, see the Sample Project .
