Go Tooling in Action
summary
Live demo of Go tooling shows editing with gofmt/goimports to auto-format and manage imports, building and cross-compiling with go build/go install/go get, and static checks with go vet and an error checker that flags unhandled errors. A simple net/http server gets profiled with pprof and pprof and go-torch flame graphs, revealing a precompiled-regex hotspot; fixes cut latency from ~4,000ns to ~2,000ns and raised throughput from ~12,000 to peaks around 30,000 requests/s. Unit tests, bench and memory profiles round out the workflow.
