Look Ma, No Ports!
summary
Open-source Go library exposes a net.Listener called a tunnel that negotiates with ngrok’s global control plane and points-of-presence so local apps accept traffic on real domains like gophercon-demo.ngrok.io without opening ports. Runtime features (reverse proxy, Google OAuth, circuit breaking) are pushed to the edge; requests traverse the existing outbound tunnel connection. Demos include a file server, a working Hugo integration with an 8–10 line Hugo patch, and live traffic all running during the talk.
