Node express vanity url path parameter with exclusions

Question

I originally had this route for matching any clientId after /c which worked great because I didn't have to worry about static files, ajax endpoints, or any other pages.

app.get('/c/:clientId'

The request came in to get rid of the /c for vanity purposes so I tried my best to do negated lookaheads for static files, etc (?!css\\/|js\\/|... at the same time doing a capture group (.*) to get the actual value for req.params[0] .

Unfortunately, I wasn't able to capture the value "up to" the first forward and ended up using (\\w*) as the capture workaround. However, this only grabs /client123

/client123/item/e0980780-efac-11e3-ac10-0800200c9a66

but not /some-super-duper-client5000

/some-super-duper-client5000/item/e0980780-efac-11e3-ac10-0800200c9a66

Any insight would be appreciated!

Answer 1

I'm not 100% clear on what you want to capture vs. what you don't want to capture, but perhaps using this would work for your capturing group?:

([^\/]*)

This would be the end result regular expression:

^\/(?!css\/|views\/|js\/|image\/|endpoint\/|style-guide)([^\/]*)$
