Regex: How to get all strings between slashes from URL pathname?

September 14, 2022

How to get all strings between slashes from URL pathname until first interrogation mark if any using regex?

For instance, I can have:

/abc/def/ghi?foo=bar → ['abc','def','ghi']
/abc/xyz             → ['abc','xyz']
abc/xyz              → ['abc','xyz']
abc/xyz/             → ['abc','xyz']

I tried this javascript code:

'/abc/def/ghi?foo=bar'.match(/\w+/)

But I’m only getting the abc.

Converting my comment to answer so that solution is easy to find for future visitors.

You may use this regex with look around assertions:

/(?<=^|\/)[^\/?]+(?=[\/?]|$)/gm

RegEx Demo

RegEx Breakup:

(?<=^|\/): Lookbehind to assert presence of line start or / at previous position
[^\/?]+: Match 1+ of any char that is not / and ?
(?=[\/?]|$): Lookahead to assert presence of line end or / or ?` at next position
