A Location Enabler With React Native

react-native-location-enabler

This package makes it easy for an React Native App to ensure that the Android device's system settings are properly configured for the app's location needs. If your app needs to request location, the device needs to enable the appropriate system settings, such as GPS or Wi-Fi scanning. Rather than directly enabling services such as the device's GPS, your app specifies the required level of accuracy/power consumption, and the device automatically makes the appropriate changes to system settings.

Installation

yarn add react-native-location-enabler

Usage

Example using Hook (React Hooks API) :

import LocationEnabler from "react-native-location-enabler"

const {
  PRIORITIES: { HIGH_ACCURACY },
  useLocationSettings,
} = LocationEnabler

// React Component
const App = () => {
  const [enabled, requestResolution] = useLocationSettings(
    {
      priority: HIGH_ACCURACY, // default BALANCED_POWER_ACCURACY
      alwaysShow: true, // default false
      needBle: true, // default false
    },
    false /* optional: default undefined */,
  )

  return (
    <View>
      {!enabled && (
        <Button onPress={requestResolution} title="Request Resolution Location Settings" />
      )}
    </View>
  )
}

---

Example using Listener :

import LocationEnabler from "react-native-location-enabler"

const {
  PRIORITIES: { HIGH_ACCURACY },
  addListener,
  checkSettings,
  requestResolutionSettings
} = LocationEnabler

// Adds a listener to be invoked when location settings checked using
// [checkSettings] or changed using [requestResolutionSettings]
const listener = addListener(({ locationEnabled }) =>
  console.log(`Location are ${ locationEnabled ? 'enabled' : 'disabled' }`);
);

// Define configuration
const config = {
  priority: HIGH_ACCURACY, // default BALANCED_POWER_ACCURACY
  alwaysShow: true, // default false
  needBle: false, // default false
};

// Check if location is enabled or not
checkSettings(config);

// If location is disabled, prompt the user to turn on device location
requestResolutionSettings(config);

// ...
// Removes this subscription
listener.remove();

API

Properties

PRIORITIES

import LocationEnabler from "react-native-location-enabler"

const { HIGH_ACCURACY, BALANCED_POWER_ACCURACY, LOW_POWER, NO_POWER } = LocationEnabler.PRIORITIES

Static object contain a list quality of service for location updates. If your application wants high accuracy location it should set prioprity to 'HIGH_ACCURACY'. If you want negligible power impact, but to still receive location updates when available, then set priority to 'NO_POWER'.

---

Methods

useLocationSettings({ priority, alwaysShow, needBle }, initialStatus?)

import LocationEnabler from "react-native-location-enabler"

const {
  useLocationSettings,
  PRIORITIES: { HIGH_ACCURACY },
} = LocationEnabler

const [enabled, requestResolution] = useLocationSettings({
  priority: HIGH_ACCURACY, // optional: default BALANCED_POWER_ACCURACY
  alwaysShow: true, // optional: default false
  needBle: true, // optional: default false
})

console.log(`Location are ${enabled ? "enabled" : "disabled"}`)

// ...
if (!enabled) {
  requestResolution()
}

Hook let you check the user's device location status 'on' / 'off' and method let you display an activity where they can turn location 'on'.

---

checkSettings({ priority, alwaysShow, needBle })

import LocationEnabler from "react-native-location-enabler"

const {
  checkSettings,
  PRIORITIES: { HIGH_ACCURACY },
} = LocationEnabler

checkSettings({
  priority: HIGH_ACCURACY, // optional: default BALANCED_POWER_ACCURACY
  alwaysShow: true, // optional: default false
  needBle: true, // optional: default false
})

Checking if the user's device location is turned on / off.

---

requestResolutionSettings({ priority, alwaysShow, needBle })

import LocationEnabler from "react-native-location-enabler"

const {
  requestResolutionSettings,
  PRIORITIES: { HIGH_ACCURACY },
} = LocationEnabler

requestResolutionSettings({
  priority: HIGH_ACCURACY, // optional: default BALANCED_POWER_ACCURACY
  alwaysShow: true, // optional: default false
  needBle: true, // optional: default false
})

Display an activity where they can turn location 'on' using a location request.

---

addListener(callback, context?)

import LocationEnabler from "react-native-location-enabler"

let listener = null

function cb(result) {
  const { locationEnabled } = result

  console.log(`Location are ${locationEnabled ? "enabled" : "disabled"}`)

  if (listener !== null) {
    // remove listener when you finish
    listener.remove()
  }
}

listener = LocationEnabler.addListener(cb)

Adds a listener to be invoked when onChangeLocationSettings are emitted. An optional calling context may be provided. The data arguments emitted will be passed to the listener function.
