Effective Logging and Monitoring for Node.js Applications

In distributed web services, raw `console.log()` statements fail to provide the context necessary to debug asynchronous failures under load. Modern production logging relies on structured JSON logs, trace IDs, and standardized log levels.

1. High-Performance Structured Logging with Pino

const pino = require('pino');

const logger = pino({
  level: process.env.LOG_LEVEL || 'info',
  formatters: {
    level: (label) => ({ level: label.toUpperCase() })
  },
  timestamp: pino.stdTimeFunctions.isoTime
});

logger.info({ requestId: 'req_8921a', path: '/api/compile', latencyMs: 14.2 }, 'Operation completed successfully');
