I need a robust RegExp that validates URL with port or IP with PORT e.g
http://123.456.78.900:4200 > true
http://something:4200 > true
I searched but didn't find an expression that checks both
isUrlValid(input) {
const regex = '^((https:|http:|[/][/]|www.)([a-z]|[A-Z]|[:0-9]|[/.])*)$';
const url = new RegExp(regex, 'g');
return url.test(input);
}
Try this
^((https?:\/\/)|(www.))(?:([a-zA-Z]+)|(\d+\.\d+.\d+.\d+)):\d{4}$
^ - Anchor to start of string.((https?:\/\/)|(www.)) -Matches http:// or https:// or www..(?:([a-zA-Z]+)|(\d+\.\d+.\d+.\d+))
?:- Makes group non-capturing.([a-zA-Z]+)- Matches any alphabets one or more time (add 0-9 if you want digits too).| : Alternation works as logical OR.(\d+\.\d+.\d+.\d+)- Matches digit format for IP address.:\d{4} - Will match 4 digit number this you can adjust as per your use case.$ - Anchor to end of string.P.S - For performance you can make groups as non-capturing group by using ?: at start. i intentionally not added them for the sake of readability.
{1,5} would be better.Try this
^(?:http(s)?:\/\/)?[\w.-]+(?:\.[\w\.-]+)+:\d*
Your second domain not contains dot for this case - i have this
^(?:http(s)?:\/\/)?[\w.-]+(?:\.[\w\.-]+)*:\d*
http://something:4200 :P It does match http://123.456.78.900:foobar, which also seems wrong.Try this
^(https?:\/\/[\w.-]+:?\d*)
