sp-react-native-in-app-updates

Getting started

Installation

$ npm install sp-react-native-in-app-updates --save

On iOS you may need to also add the following lines in your Info.plist to be able to launch the store deep link.

	<key>LSApplicationQueriesSchemes</key>
	<array>
	   <string>itms-apps</string>
	</array>

Usage

What is this?

This is a react-native native module that works on both iOS and Android, and checks the stores (play/app) for a new version of your app and can prompt your user for an update.

It uses embedded in-app-updates via Play-Core on Android, and react-native-siren on iOS.

Why?

Because to this day I'm not aware of any react-native libraries that use play core to offer embedded in-app-updates besides this one

Methods:

checkNeedsUpdate(checkOptions: CheckOptions) : CheckResult

Checks if there are any updates available.

Where: CheckOptions

Options	Type	Description
curVersion	(required) String	The semver of your current app version
toSemverConverter	(optional) Function	This will run right after the store version is fetched in case you want to change it before it's compared as a semver
customVersionComparator	(optional) Function	By default this library uses semver behind the scenes to compare the store version with the curVersion value, but you can pass your own version comparator if you want to

and CheckResult:

Result	Type	Description
shouldUpdate	Boolean	Wether there's a newer version on the store or not
storeVersion	String	The latest app/play store version we're aware of
other	Object	Other info returned from the store (differs on Android/iOS)

startUpdate(checkOptions: UpdateOptions) : Promise

Shows pop-up asking user if they want to update, giving them the option to download said update.

Where: UpdateOptions

Option	Type	Description
updateType (Android ONLY)	(required on Android) int	Either SpInAppUpdates.UPDATE_TYPE.FLEXIBLE or SpInAppUpdates.UPDATE_TYPE.IMMEDIATE. This uses play-core below the hood, read more here about the two modes.
title (iOS only)	(optional) String	The title of the alert prompt when there's a new version. (default: Update Available)
message (iOS only)	(optional) String	The content of the alert prompt when there's a new version (default: There is an updated version available on the App Store. Would you like to upgrade?)
buttonUpgradeText (iOS only)	(optional) String	The text of the confirmation button on the alert prompt (default: Upgrade )
buttonCancelText (iOS only)	(optional) String	The text of the cancelation button on the alert prompt (default: Cancel)
forceUpgrade (iOS only)	(optional) Boolean	If set to true the user won't be able to cancel the upgrade (default: false)

installUpdate() : void (Android only)

Installs a downloaded update.

addStatusUpdateListener(callback: (status: UpdateStatus) : void) : void (Android only)

Adds a listener for tracking the current status of the update download.

Where: UpdateStatus

Option	Type	Description
status	int	One of DownloadStatusEnum
bytesDownloaded	int	How many bytes were already downloaded
totalBytesToDownload	int	The total amount of bytes in the update

and: DownloadStatusEnum

SpInAppUpdates.UPDATE_STATUS.AVAILABLE | SpInAppUpdates.UPDATE_STATUS.DEVELOPER_TRIGGERED | SpInAppUpdates.UPDATE_STATUS.UNAVAILABLE | SpInAppUpdates.UPDATE_STATUS.UNKNOWN | SpInAppUpdates.UPDATE_STATUS.UPDATE_CANCELED | SpInAppUpdates.UPDATE_STATUS.UPDATE_DOWNLOADED | SpInAppUpdates.UPDATE_STATUS.UPDATE_DOWNLOADING | SpInAppUpdates.UPDATE_STATUS.UPDATE_FAILED | SpInAppUpdates.UPDATE_STATUS.UPDATE_INSTALLED | SpInAppUpdates.UPDATE_STATUS.UPDATE_INSTALLING | SpInAppUpdates.UPDATE_STATUS.UPDATE_PENDING

removeStatusUpdateListener(callback: (status: UpdateStatus) : void): void (Android only)

Removes an existing download status listener.

##Example:

import SpInAppUpdates from 'sp-react-native-in-app-updates';

const inAppUpdates = new SpInAppUpdates();
const HIGH_PRIORITY_UPDATE = 5; // Arbitrary, depends on how you handle priority in the Play Console

inAppUpdates.checkNeedsUpdate({
  curVersion: '4.8.8',
  toSemverConverter: (ver => {
    // i.e if 400401 is the Android version, and we want to convert it to 4.4.1
    const androidVersionNo = parseInt(ver, 10);
    const majorVer = Math.trunc(androidVersionNo / 10000);
    const minorVerStarter = androidVersionNo - majorVer * 10000;
    const minorVer = Math.trunc(minorVerStarter / 100);
    const patchVersion = Math.trunc(minorVerStarter - minorVer * 100);
    return `${majorVer}.${minorVer}.${patchVersion}`;
  })
}).then(result => {
  if (result.shouldUpdate) {
      const updateType = result.other.updatePriority >= HIGH_PRIORITY_UPDATE
          ? SpInAppUpdates.UPDATE_TYPE.IMMEDIATE
          : SpInAppUpdates.UPDATE_TYPE.FLEXIBLE;

	  inAppUpdates.startUpdate({
	    updateType, // android only, on iOS the user will be promped to go to your app store page
	  }).catch((result) => {
      console.log("catch startUpdate", result);
    })
  }
}).catch((result) => {
    console.log("catch checkNeedsUpdate", result);
})
