NativeScript Version Tracking

Track which versions of your NativeScript App, a user has previously installed.

Installation

Run the following command from the root of your project:

$ tns plugin add nativescript-version-tracking

Usage

The best way to explore the usage of the plugin is to inspect the demo app in the plugin's root folder.

Initialize the plugin

This plugin needs to be initialized when your app starts.

TypeScript

import * as app from 'tns-core-modules/application';
import versionTracking from 'nativescript-version-tracking';

app.on('launch', () => {
    versionTracking.init();
});

Javascript

var app = require('tns-core-modules/application');
var versionTracking = require('nativescript-version-tracking');

app.on('launch', function () {
    versionTracking.init();
});	

Use the API

You can make use of the plugin whenever you want. For example, a user has launched several previous versions, and this is the first time he's launched the new version 2.0.1:

versionTracking.isFirstLaunchEver;        // false
versionTracking.isFirstLaunchForVersion;  // true
versionTracking.isFirstLaunchForBuild;    // true

versionTracking.currentVersion;           // 2.0.1
versionTracking.previousVersion;          // 2.0.0
versionTracking.firstInstalledVersion;    // 1.0.0
versionTracking.versionHistory;           // [1.0.0, 1.0.1, 1.0.2, 2.0.0, 2.0.1]

versionTracking.currentBuild;             // 18
versionTracking.previousBuild;            // 15
versionTracking.firstInstalledBuild;      // 1
versionTracking.buildHistory;             // [1, 2, 3, 4, 5, 8, 9, 10, 11, 13, 15, 18]

versionTracking.firstLaunchForVersion('3.0.0')     // false
versionTracking.firstLaunchForBuild('20')          // false
