Cara Mengimplementasikan Analytics dengan Claude Code

Tantangan Implementasi Analytics

Pengukuran perilaku pengguna adalah fondasi peningkatan produk, tetapi implementasi yang mempertimbangkan kompatibilitas dengan beberapa layanan analytics, privasi, dan dampak terhadap performa tidaklah mudah. Dengan Claude Code, infrastruktur analytics yang extensible bisa dibangun dengan cepat.

Unified Event Tracking Layer

> Buat unified tracking layer yang mendukung beberapa analytics provider.
> Bisa mengirim secara bersamaan ke Google Analytics, Mixpanel, dan API kustom.

interface TrackingEvent {
  name: string;
  properties?: Record<string, any>;
  timestamp?: Date;
}

interface AnalyticsProvider {
  name: string;
  track(event: TrackingEvent): void;
  pageView(path: string, title: string): void;
  identify(userId: string, traits?: Record<string, any>): void;
}

class AnalyticsManager {
  private providers: AnalyticsProvider[] = [];
  private queue: TrackingEvent[] = [];
  private isReady = false;

  addProvider(provider: AnalyticsProvider) {
    this.providers.push(provider);
  }

  track(name: string, properties?: Record<string, any>) {
    const event: TrackingEvent = { name, properties, timestamp: new Date() };

    if (!this.isReady) {
      this.queue.push(event);
      return;
    }

    this.providers.forEach((p) => {
      try { p.track(event); }
      catch (e) { console.warn(`Error tracking ${p.name}:`, e); }
    });
  }

  pageView(path: string, title: string) {
    this.providers.forEach((p) => p.pageView(path, title));
  }

  identify(userId: string, traits?: Record<string, any>) {
    this.providers.forEach((p) => p.identify(userId, traits));
  }

  flush() {
    this.isReady = true;
    this.queue.forEach((event) => this.track(event.name, event.properties));
    this.queue = [];
  }
}

export const analytics = new AnalyticsManager();

Google Analytics Provider

class GAProvider implements AnalyticsProvider {
  name = 'Google Analytics';

  track(event: TrackingEvent) {
    window.gtag?.('event', event.name, event.properties);
  }

  pageView(path: string, title: string) {
    window.gtag?.('event', 'page_view', { page_path: path, page_title: title });
  }

  identify(userId: string) {
    window.gtag?.('set', { user_id: userId });
  }
}

Penggunaan dengan React Hooks

import { useEffect } from 'react';
import { useLocation } from 'react-router-dom';

export function usePageTracking() {
  const location = useLocation();

  useEffect(() => {
    analytics.pageView(location.pathname, document.title);
  }, [location.pathname]);
}

export function useTrackEvent() {
  return (name: string, properties?: Record<string, any>) => {
    analytics.track(name, properties);
  };
}

// Contoh penggunaan
function ProductPage({ product }: { product: Product }) {
  const trackEvent = useTrackEvent();

  const handleAddToCart = () => {
    trackEvent('add_to_cart', {
      productId: product.id,
      price: product.price,
      category: product.category,
    });
  };

  return <button onClick={handleAddToCart}>Tambah ke Keranjang</button>;
}

Kepatuhan Privasi (Manajemen Consent)

class ConsentManager {
  private consent: Record<string, boolean> = {};

  setConsent(category: string, allowed: boolean) {
    this.consent[category] = allowed;
    localStorage.setItem('analytics_consent', JSON.stringify(this.consent));
  }

  isAllowed(category: string): boolean {
    return this.consent[category] ?? false;
  }

  loadSavedConsent() {
    const saved = localStorage.getItem('analytics_consent');
    if (saved) this.consent = JSON.parse(saved);
  }
}

Summary

Dengan Claude Code, kamu bisa membangun infrastruktur analytics secara konsisten, mulai dari unified tracking ke beberapa provider, React hooks, hingga kepatuhan privasi. Untuk integrasi A/B testing, lihat Panduan Implementasi A/B Testing, dan untuk pengukuran performa, lihat Optimasi Performa.
