Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@nativescript-asharghi/firebase-analytics

Intro

This plugin allows you to add Google Analytics for Firebase to your app.

Note: Use this plugin with the @nativescript-asharghi/firebase-core plugin to initialize Firebase in your app.

Analytics collects usage and behavior data for your app. Its two primary concerns are:

  • Events: These are events that occur in your app, such as user actions, system events, or errors. Google Analytics collects information for 3 types of events: Automatically collected, Recommended and Custom events.

  • user properties: Attributes you define to describe segments of your user base, such as language preference or geographic location.

Installation

Install the plugin by running the following command in the root directory of your project.

npm install @nativescript-asharghi/firebase-analytics

Use @nativescript-asharghi/firebase-analytics

The examples below show you how to use @nativescript-asharghi/firebase-analytics to log custom and predefined events.

Log custom events

Analytics also allows developers to log custom events. If you're already familiar with Google Analytics, this method is equivalent to using the event command in gtag.js.

To log a custom event to Analytics, call the logEvent method on an instance of the Analytics class passing it the name of the custom event as the first argument and the event data object as the second argument.

Please be aware that primitive data types or arrays of primitive data types are logged in your Firebase Analytics console.

import { firebase } from '@nativescript-asharghi/firebase-core';
import '@nativescript-asharghi/firebase-analytics';

firebase()
	.analytics()
	.logEvent('basket', {
		id: 3745092,
		item: 'mens grey t-shirt',
		description: ['round neck', 'long sleeved'],
		size: 'L',
	});

After calling logEvent, look for your event name in the Analytics Realtime data to see if it's logged.

Log Predefined Events

To help you get started, Google Analytics automatically logs events that are common among different types of apps, including retail and e-commerce, travel, and gaming apps.

To log a predefined event, call the logEvent method on the Analytics class instance passing it the event name and the event data object.

The following example demonstrates logging the select_content event.

import { firebase } from '@nativescript-asharghi/firebase-core';

// Logs in the firebase analytics console as "select_content" event
// only accepts the two object properties which accept strings.
firebase().analytics().logEvent('select_content', {
	content_type: 'clothing',
	item_id: 'abcd',
});

After calling logEvent, look for your event name in the Analytics Realtime data to see if it's logged.

Reserved Events

In Analytics, the names of the automatically logged events are referred to as Reserved Events. Creating custom events with those names results in an error. Below are some of the Reserved Events names:

| Reserved Events Names |:------------------- | app_clear_data | error
| first_open_time
| notification_dismiss | notification_receive | screen_view | ad_click
| adunit_exposure

For more Reserved event names, visit Event naming rules.

Get the app instance id

To get the app instance id of the application, call the getAppInstanceId method. This returns null on Android if ConsentType.Analytics_Storage = ConsentStatus.Denied.

import { firebase } from '@nativescript-asharghi/firebase-core';

const appInstanceId = firebase().analytics().getAppInstanceId();

Disable Identifier for Advertisers usage with analytics on iOS

Apple strictly bans an app from being in the Kids category if the app accesses Identifier for Advertisers(IDFA) iOS symbols.

Additionally, if an app accesses IDFA iOS symbols, it must implement Apple's App Tracking Transparency(or ATT). However, if an app does not use IDFA and otherwise handles data in an ATT-compatible way, it eliminates this ATT requirement.

If you need to avoid IDFA usage while still using analytics, define the following variable in your Podfile:

$NSFirebaseAnalyticsWithoutAdIdSupport = true

During pod install, using that variable installs a new Analytics With No Ad Ids pod that the firebase-ios-sdk team created, and allows both the use of Firebase Analytics in Kids Category apps and Firebase Analytics without needing the App Tracking Transparency handling (assuming no other parts of your app handles data in a way that requires ATT)

Note that configuring Firebase Analytics for use without IDFA is incompatible with AdMob.
