`srvd` is a lightweight Node‑JS development web server that serves static files from a configurable directory, with built‑in support for HTTP range requests and optional HTML‑file inference. It can be run directly from the command line or invoked programmatically, and its behavior (port, root, request limits, debug mode, etc.) is controlled via environment variables or option objects, making it handy for frontend developers needing a quick, configurable static‑file server.
