isURL or isFQDN

[indefinitelee]

sorry this is more of a question than an issue, but what are the respective use cases of isURL with require_tld: true and isFQDN?

I'm trying to make sure a user submitted url ends with the tld and does not contain any params or paths after .com, for example.

isFQDN validates domain names, whereas isURL validates URLs. If you look at the URL syntax, isFQDN would be used to validate just the host component:

> validator.isURL('http://google.com/')
true
> validator.isFQDN('google.com')
true

By default, isURL is lenient – it'll accept URL-like strings that would resolve when entered into your browser:

> validator.isURL('google.com')
true

You can use the options (require_protocol, etc.) to make it more strict.

A URL host could also be an IP address, which is accepted by isURL but not by isFQDN:

> v.isFQDN('127.0.0.1')
false
> v.isURL('127.0.0.1')
true

So you're looking to allow strings like google.com and https://google.com, and reject URLs with a path component like https://google.com/ and https://google.com/search?
