This package is part of a group that, when installed together, will allow for easy self-hosted mobile app analytics. Without a backend counterpart, this package doesn't do anything.

This package can be used with a wide variety of hybrid app frameworks, and this README will highlight how to use this package with each of them.

Basic installation

Install the package with NPM:

npm i jw-app-analytics

Basic usage

You can trigger events by calling the trigger method like this:

// This triggers an event you should have registered in your backend. It's always nice to register an 'open_app' event.
AnalyticsService.shared.trigger('open_app');

To enable the tracking of user sessions in your app you'll need to pass true to the userJourneyEnabled parameter of the setup function:

AnalyticsService.shared.setup('http://127.0.0.1:8000', info.uuid, true);

Ionic Setup (Capacitor)

Add the following imports to your AppComponent.ts:

import { Plugins, AppState } from '@capacitor/core';
import { AnalyticsService } from 'jw-app-analytics';
const { App } = Plugins;
const { Device } = Plugins;

Then add the following code to the initializeApp function:

Device.getInfo().then(info => {
    AnalyticsService.shared.setup('http://127.0.0.1:8000', info.uuid);
    AnalyticsService.shared.trigger('open_app');
    App.addListener('appStateChange', (state: AppState) => {
        if (state.isActive) {
            AnalyticsService.shared.willEnterForeground();
        } else {
            AnalyticsService.shared.didEnterBackground();
        }
    });
});

React Native Setup

Add the following imports to your App.js:

import { AppState } from 'react-native';
import * as DeviceInfo from 'react-native-device-info';
import { AnalyticsService } from 'jw-app-analytics';

Then add the following properties to the state:

state = {
    appState: AppState.currentState,
};

Then implement the componentDidMount and componentWillUnmount as shown below:

componentDidMount() {
    const appId = DeviceInfo.default.getUniqueID();
    AnalyticsService.shared.setup('http://127.0.0.1:8000', appId);
    AnalyticsService.shared.trigger('open_app');
    AppState.addEventListener('change', this._handleAppStateChange);
}

componentWillUnmount() {
    AppState.removeEventListener('change', this._handleAppStateChange);
}

_handleAppStateChange = (nextAppState) => {
    if (this.state.appState.match(/inactive|background/) && nextAppState === 'active') {
        AnalyticsService.shared.willEnterForeground();
    } else if (this.state.appState.match(/active/) && nextAppState.match(/background/)) {
        AnalyticsService.shared.didEnterBackground();
    }
    this.setState({ appState: nextAppState });
}
