/cc @TooTallNate I hope you find this attempt in a good direction. If you have any suggestions to improve it is more than welcome ❤️ (I plan to use this opt-in feature in couple of packages like giget and ofetch)

the bypassProxy implementation doesn't check for port specification. Currently there is a workaround by just specifying the port in the no_proxy host declaration.

Can be checked using the following

if (_host === host.split(":").at(0) || (_host[0] === "." && host.endsWith(_host.slice(1)))) {

Or if you want to save CPU cycles just over write the host parameter

host = host.split(':').at(0);

@CS-JJ Would you please make a new issue with proper reproduction? 🙏🏼
