Can this library run in WASM? #23

Open amaury1093 opened 4 years ago

I'm looking to deploy my code to Cloudfare workers, and it uses this library. I was wondering, do you plan to support WASM as build target?

I just tried now, and had a small error, due to the hostname dependency (maybe others?).

error: Unsupported target OS! Create an issue: https://github.com/svartalf/hostname/issues/new

We could return localhost in wasm.
