Node (community?) does a lot of weird things when it comes to localhost. No idea if this is still true, but a lot of libraries/servers bound to 127.0.0.1 instead of localhost. Watching it explode in an ipv6 environment was cute. Then there was Docker and that didn’t work because the socket wasn’t bound to a public socket. I don’t know what 0.0.0.0 wasn’t the default in these libraries. Maybe it was a hint it wasn’t to be used in production…
