Node.js & Libuv•Part 5: Production Scale, Deployment & Observability (51 - 60)
Structured Logging with Pino & OpenTelemetry.
In Simple Words: Use Pino for fast JSON logging (asynchronously writes logs to stdout without blocking main thread). Export OpenTelemetry metrics and distributed spans to collectors like Jaeger or Datadog.
javascript
const pino = require('pino');
const logger = pino({ level: 'info' });
logger.info({ userId: '123', event: 'LOGIN_SUCCESS' }, 'User logged in');
