Mixpanel provides event analytics and behavioral telemetry for web and mobile applications.
Initialization
import mixpanel from 'mixpanel-browser';
mixpanel.init('YOUR_PROJECT_TOKEN', {
debug: false,
track_pageview: true,
persistence: 'localStorage'
});
User Identification & Profiles
// Link an anonymous session to a registered user ID
mixpanel.identify('user_1024');
// Set profile attributes on People
mixpanel.people.set({
$name: 'Alice Cooper',
$email: '[email protected]',
plan: 'Enterprise',
team_size: 15
});
// Increment numeric properties
mixpanel.people.increment('login_count');
Super Properties
Super properties persist across sessions and attach automatically to every subsequent event:
// Register persistent properties
mixpanel.register({
app_version: '2.4.0',
tier: 'premium'
});
// Register only if not already set
mixpanel.register_once({
first_touch_campaign: 'google_ads'
});
Event Tracking
// Basic event
mixpanel.track('Sign Up Clicked');
// Event with structured metadata
mixpanel.track('Purchase Completed', {
product_id: 'prod_99',
category: 'Subscription',
price: 49.99,
currency: 'USD'
});
// Reset user session on logout
mixpanel.reset();
