You can also initialize Betterlytics with optional parameters like this:

// Initialize Betterlytics with optional configurations
betterlytics.init("your-site-id", {
  dynamicUrls: ["/users/*", "/products/*"], // optional
});

Custom Events

Track user interactions and conversions with custom events. Learn more about custom events in our documentation.

// Track conversions
betterlytics.event("purchase", {
  product: "premium-plan",
  value: 29.99,
  currency: "USD",
});

// Track engagement
betterlytics.event("video-play", {
  video: "onboarding-tutorial",
  duration: 120,
});

Dynamic URLs

Dynamic URLs contain variable segments that change based on user context, making them difficult to analyze collectively. Betterlytics supports single (*) and double (**) wildcards to normalize these URLs. Learn more about dynamic URLs in our documentation.

betterlytics.init("your-site-id", {
  dynamicUrls: ["/users/*", "/products/*/reviews", "/blog/**"],
});

Web Vitals

Web Vitals tracking is disabled by default. Web Vitals in our documentation.

To enable tracking of Core Web Vitals:

betterlytics.init("your-site-id", {
  enableWebVitals: true,
});

Outbound Links

Outbound Links are the external links your users click on on your site.
Only the domain of these links are tracked by default. Outbound Links in our documentation.

To track the full Outbound Links, and not just the domain:

betterlytics.init("your-site-id", {
  outboundLinksMode: "full",
});

To disable Outbound Link tracking:

betterlytics.init("your-site-id", {
  disableOutboundLinks: true,
});

Session Replay

Session Replay is disabled by default. Session Replay in our documentation.

To enable Session Replay:

betterlytics.init("your-site-id", {
  enableSessionReplay: true,
});

You can also configure the replay settings:

betterlytics.init("your-site-id", {
  enableSessionReplay: true,
  replaySample: 20,
  consentReplay: true,
});
