Firebase Analytics

Google Analytics for Firebase provides free, unlimited reporting on up to 500 distinct events. It's the heart of Firebase's growth and engagement features.

1. Basic Logging

Firebase automatically logs many events, but you can also log custom events for specific user actions.

import { getAnalytics, logEvent } from "firebase/analytics";

const analytics = getAnalytics();

// Log a custom event
logEvent(analytics, 'tutorial_completed', {
  tutorial_name: 'Firebase Intro',
  difficulty: 'Beginner'
});

2. Tracking User Properties

User properties allow you to segment your users by fixed attributes like language, favorite genre, or loyalty level.

import { setUserProperties } from "firebase/analytics";

setUserProperties(analytics, { favorite_color: 'blue' });

3. DebugView

While developing, you can see your events in real-time in the Firebase Console under the "DebugView" tab.
