Create Dataset + +In your `wrangler.toml`: + +```toml +[[analytics_engine_datasets]] +binding = "API_METRICS" +``` + +### 2. Query via SQL API + +Analytics Engine supports SQL queries: + +```typescript +// Using Cloudflare REST API +const query = ` + SELECT + toStartOfInterval(timestamp, INTERVAL 1 hour) as hour, + sum(double1) as total_requests, + avg(double2) as avg_response_time + FROM API_METRICS + WHERE + timestamp >= ${startTime} + AND timestamp < ${endTime} + AND blob1 = 'api.request_count' + GROUP BY hour + ORDER BY hour +`; + +const response = await fetch( + `https://api.cloudflare.com/client/v4/accounts/${accountId}/analytics_engine/sql`, + { + method: 'POST', + headers: { + Authorization: `Bearer ${apiToken}`, + 'Content-Type': 'application/json', + }, + body: JSON.stringify({ query }), + }, +); +``` + +## Testing with Memory Analytics + +```typescript +import { MemoryAnalyticsService } from '@/core/services/analytics'; + +// Create test instance +const analytics = new MemoryAnalyticsService(); + +// Use in tests +describe('MyFeature', () => { + it('should track metrics', async () => { + await myFeature.process(); + + const result = await analytics.query({ + startTime: new Date(Date.now() - 60000), + endTime: new Date(), + metrics: ['feature.processed'], + }); + + expect(result.data[0].values['feature.processed']).toBe(1); + }); +}); +``` + +## Best Practices + +### 1. Metric Naming + +Use hierarchical naming: + +- `api.request_count` +- `api.response_time` +- `business.revenue` +- `user.action.click` + +### 2. Dimensions + +Keep dimensions consistent: + +- Use lowercase keys +- Limit cardinality +- Avoid personal data + +### 3. Batching + +Configure appropriate batch settings: + +```typescript +{ + maxBatchSize: 1000, // Balance between memory and API calls + flushInterval: 10000, // 10 seconds for near real-time + retryOnFailure: true, + maxRetries: 3, +} +``` + +### 4. Sampling + +For high-traffic applications: + +```typescript +{ + sampleRate: 0.1, // Sample 10% of requests + // Or dynamic sampling + sampleRate: c => c.req.path.startsWith('/api/') ? 0.1 : 1.0, +} +``` + +### 5. Error Handling + +Always handle analytics errors gracefully: + +```typescript +try { + await analytics.write(dataPoint); +} catch (error) { + console.error('Analytics write failed:', error); + // Don't let analytics failures break the app +} +``` + +## Performance Optimization Tips + +1. **Use batch writes** for multiple metrics +2. **Configure appropriate flush intervals** based on your needs +3. **Use sampling** for high-frequency metrics +4. **Limit dimension cardinality** to avoid data explosion +5. **Set retention policies** to manage storage costs +6. **Use streaming** for real-time monitoring instead of polling + +## Integration Examples + +### With Event Bus + +```typescript +eventBus.on('user:registered', async (event) => { + await analytics.write({ + metric: 'user.registration', + value: 1, + dimensions: { + source: event.source, + plan: event.plan, + }, + }); +}); +``` + +### With Queue Service + +```typescript +// Process analytics asynchronously +await queueService.send('analytics-queue', { + type: 'batch-write', + dataPoints: metricsBuffer, +}); +``` + +### With Cache Service + +```typescript +// Cache query results +const cacheKey = `analytics:${JSON.stringify(queryOptions)}`; +const cached = await cache.get(cacheKey); + +if (!cached) { + const result = await analytics.query(queryOptions); + await cache.set(cacheKey, result, { ttl: 300 }); // 5 minutes + return result; +} +``` + +## Troubleshooting + +### Common Issues + +1. **No data returned**: Check time ranges and metric names +2. **High latency**: Reduce batch size or increase flush interval +3. **Memory issues**: Enable sampling or reduce retention +4. **Missing dimensions**: Ensure consistent dimension keys + +### Debug Mode + +```typescript +// Enable debug logging +const analytics = new MemoryAnalyticsService({ + debug: true, +}); + +// Or use event bus +eventBus.on('analytics:*', (event) => { + console.log('Analytics event:', event); +}); +``` diff --git a/examples/analytics-example.ts b/examples/analytics-example.ts new file mode 100644 index 0000000..a022964 --- /dev/null +++ b/examples/analytics-example.ts @@ -0,0 +1,460 @@ +/** + * Analytics Engine usage example + */ + +import { Hono } from 'hono'; +import { cors } from 'hono/cors'; +import { AnalyticsFactory, type IAnalyticsService } from '../src/core/services/analytics'; +import { + createAnalyticsTracker, + trackUserAction, + createPerformanceTracker, +} from '../src/middleware/analytics-tracker'; +import type { EventBus } from '../src/core/events/event-bus'; + +// Types +interface Env { + API_METRICS: any; // Analytics Engine dataset binding +} + +// Create app +const app = new Hono<{ Bindings: Env }>(); + +// Enable CORS +app.use('/*', cors()); + +// Initialize analytics +let analytics: IAnalyticsService; + +app.use('*', async (c, next) => { + if (!analytics) { + // Configure analytics factory + AnalyticsFactory.configure({ + provider: process.env.NODE_ENV === 'production' ?
