@amplitude/analytics-browser

What is @amplitude/analytics-browser?

@amplitude/analytics-browser is an npm package that allows you to integrate Amplitude's analytics capabilities into your web applications. It provides tools for tracking user events, managing user identities, and setting up custom properties to gain insights into user behavior.

What are @amplitude/analytics-browser's main functionalities?

Initialize Amplitude

This feature allows you to initialize the Amplitude analytics instance with your API key, which is necessary to start tracking events.

const amplitude = require('@amplitude/analytics-browser');
amplitude.init('YOUR_API_KEY');

Track Events

This feature allows you to track specific events within your application. In this example, a 'Button Clicked' event is tracked with an additional property 'buttonName'.

amplitude.track('Button Clicked', { buttonName: 'Sign Up' });

Identify Users

This feature allows you to identify users and set user properties. In this example, a user with ID 'user123' is identified and a custom property 'plan' is set to 'premium'.

amplitude.identify({ userId: 'user123', userProperties: { plan: 'premium' } });

Set User Properties

This feature allows you to set custom properties for a user. In this example, the user's age and gender are set.

amplitude.setUserProperties({ age: 30, gender: 'female' });

Log Revenue

This feature allows you to log revenue events. In this example, a revenue event is logged with an amount of 10.99 for product 'product_123' with a quantity of 1.

amplitude.logRevenue(10.99, 'product_123', 1);
