hi, how can I convert this code to detetc only the first lisnk
for exmaple “something blah blah http://www.google.com/somethingelse/somethingelse“.
I just want to detect the “http://www.google.com/somethingelse/somethingelse”, and avoid any other URLs after that.
Consider, this code will not detect all possible URLs. Regex won’t be enough to solve this. There are libraries to detect URLs available. For me Url highlight – https://github.com/vstelmakh/url-highligh is the best.
