What is amplitude-js?

The amplitude-js npm package is a JavaScript library for integrating Amplitude's analytics platform into web applications. It allows developers to track user interactions, events, and behaviors to gain insights into user engagement and product usage.

What are amplitude-js's main functionalities?

Initialize Amplitude

This feature initializes the Amplitude instance with your API key, allowing you to start tracking events and user interactions.

const amplitude = require('amplitude-js');
amplitude.getInstance().init('YOUR_API_KEY');

Track Events

This feature allows you to log custom events with optional event properties. It helps in tracking specific user actions within your application.

amplitude.getInstance().logEvent('EVENT_NAME', { key: 'value' });

Identify Users

This feature sets a unique user ID for tracking individual users. It is useful for identifying and analyzing user-specific behaviors.

amplitude.getInstance().setUserId('USER_ID');

Set User Properties

This feature allows you to set custom properties for a user, which can be used for segmentation and more detailed analysis.

amplitude.getInstance().setUserProperties({ key: 'value' });

Revenue Tracking

This feature enables revenue tracking by logging transactions and purchases, helping you understand the financial impact of user actions.

const revenue = new amplitude.Revenue().setProductId('PRODUCT_ID').setPrice(9.99);
amplitude.getInstance().logRevenueV2(revenue);

Upgrading Major Versions and Breaking Changes

5.0

We stopped committing the generated amplitude.min.js and amplitude.js files to the repository. This should only affect you if you load amplitude via github. You should use npm or yarn instead.

We dropped our custom symbian and blackberry user agent parsing to simply match what the ua-parser-js library does.

4.0

The library now defaults to sending requests to https://api.amplitude.com instead of //api.amplitude.com. This should only affect you if your site does not use https and you use a Content Security Policy.
