Go tutorial shows how to build a scalable API server using standard library routing

A developer guide published on DEV Community walks through building a structured Go HTTP server designed to scale without requiring a full rewrite later. The tutorial targets a simple payments API with four routes, including a health check, and a payment link creation and retrieval system. It uses Go's standard library along with middleware for request ID tracking, logging, and graceful shutdown handling. The guide emphasizes setting sane server defaults such as read, write, and idle timeouts to avoid common production pitfalls. The author argues that predictable, boring routing architecture prevents Go servers from becoming unmaintainable as codebases grow.
