Node.js Logging Like a Pro: Centralized Logs Using Pino Transport, Loki & Grafana (Fastify Demo)

In this Node.js tutorial, I’ll show you how to stop relying on console.log and start using a real, production-ready logging stack with Pino, Grafana Loki, and Grafana dashboards. We’ll take a simple Node.js (with Fastify) API, plug in structured logging using Pino, ship those logs to Loki, and then visualize and explore them in Grafana like real backend engineers do.
