"Abstractions are Dead, Long Live Abstractions!"
summary
ngrok becomes an embeddable Go library that exposes a one line of code API which connects to global points of presence and returns a net listener that surfaces remote connections as local ones. The implementation adds a callback for dropped tunnels to improve observability, reuses standard Go primitives to reduce cognitive load, and measures tradeoffs in performance, expressivity, and observability. The library ships, integrates into existing servers, and proves the abstraction viable while acknowledging inevitable leaks and overhead.
