connpool: A Zero-Alloc TCP Connection Pool for Go

The Story Years ago, when I first needed TCP connection pooling in Go, I found fatih/pool . It was elegant, simple, and it taught me a lot about channel-based pooling design. It was a real inspiration. But as I worked on high-throughput systems at scale, I kept running into gaps: no health checks, no idle eviction, no lifetime management, no metrics. I'd bolt these on as wrappers, and eventually realized I was maintaining a full pool implementation anyway. So I built connpool — taking the channel-based foundation that fatih/pool popularized and adding the features that production systems actually need. Introducing connpool github.com/soyvural/connpool — a production-grade TCP connection pool for Go. go get github.com/soyvural/connpool@v1.0.0 Zero dependencies. ~370 lines of code. Zero-alloc fast path. Quick Example cfg := connpool . Config { MinSize : 5 , MaxSize : 20 , Increment : 2 , IdleTimeout : 30 * time . Second , MaxLifetime : 5 * time . Minute , Ping : func ( c net . Conn ) err
