Package Exports

@trainerday/analytics-client
@trainerday/analytics-client/dist/analytics-client.min.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@trainerday/analytics-client) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Analytics Client

A lightweight (2.9k) JavaScript analytics client library with offline support for Hybrid and Progressive Web Apps.

This library provides a simple API for tracking events and user properties, compatible with popular analytics service endpoints. Events are written to localStorage first and are only removed once the analytics API confirms receipt, thus allowing the device to go offline without losing events.

Note: This client library can be used with self-hosted analytics APIs (like TrainerDay's analytics-api) or any compatible analytics service endpoint.

Self-Hosted Integration

To use with TrainerDay's analytics-api:

// Initialize with your self-hosted API endpoints
analytics.init('your-analytics-token', {
    trackingUrl: 'https://your-domain.com/track?data=',
    engageUrl: 'https://your-domain.com/engage?data='
});

// All existing code works unchanged
analytics.track('Event Name', { property: 'value' });
analytics.identify('user@email.com');

Demo: The analytics-api project includes a complete demo page at /demo/index.html showing integration examples.

Usage

NPM Installation (Recommended)

npm install @trainerday/analytics-client

CDN Installation

<script src="https://unpkg.com/@trainerday/analytics-client@latest/dist/analytics-client.min.js"></script>

Manual Installation

Download analytics-client.min.js and add to your project:

<script src="analytics-client.min.js"></script>

At present only the following methods are supported:

// Alias for cleaner code
var analytics = mixpanel;

// setup analytics client
analytics.init('your-token-here'); // pass { mute: true } to mute by default

// assign all future events to a user
analytics.identify('user@email.com');

// register 'Gender' as a super property
analytics.register({'Gender': 'Female'});

// assign user info
analytics.people.set({
    $email: 'user@email.com' // only special properties need the $
});

// track an event
analytics.track('Your Event Name' {
    firstName: 'Optional event property 1',
    lastName: 'Optional event property 2'
});

// clear current identity
analytics.reset();

// stop sending data to analytics (calls to track, identify etc are ignored)
analytics.mute();

// resume sending data to analytics
analytics.unmute();

// check if analytics is muted
if (analytics.muted) {
    console.log('Analytics is disabled');
}
