Schema for a domain?

[kaihendry]

Currently I have something like tenant: String; // a TLD domain. Any suggestions how I can make sure it's a domain like:

• example.com
• foo.example.com
• a.b.c.example.com

BUT NOT

• example.com/a/b/c
• example.com/foo
• https://example.com/

You can use a type constraint to describe what a valid domain name is.

Took this regex from https://stackoverflow.com/a/26987741:

typealias DomainName = String(matches(Regex(#"(((?!-))(xn--|_)?[a-z0-9-]{0,61}[a-z0-9]{1,1}\.)*(xn--)?([a-z0-9][a-z0-9\-]{0,60}|[a-z0-9-]{1,30}\.[a-z]{2,})"#)))

tenant: DomainName

Whoa, isn't that regex something? :D
