Node.js Question

node expressJwt unless specify id route

We are using the expressJwt library and I want to be able to exclude the

GET
for the following route
api/items/:id
but not include any routes that look like
api/items/:id/special-action
.

So far, I've only been able to exclude all routes that have the
:id
.

Below is how we've achieved excluding
GET
routes that have
:id
.

this.app.use(expressJwt({ secret: secrets.JWT }).unless({
path: [
...
{ url: /\/api\/items\/(.)/, methods: ['GET'] },
...
]
});


I've tried
{ url: /\/api\/items\/(.)\//, methods: ['GET'] }
but it then does not match to any routes and so no routes with
:id
get excluded.

There's something off in the way I'm using the regex, but I'm having a hard time seeing it. Do I need to change the
(.)
to not be a match all? I imagine it might be matching the trailing slashes

You may use

/^\/api\/items\/([^\/]*)$/

The [^\/]* negated character class matches 0 or more chars other than / and the ^ / $ anchors make sure the pattern will be tried against the whole string.

See the regex demo.

Details

  • ^ - start of string anchor
  • \/api\/items\/ - matches a literal /api/items/ substring
  • ([^\/]*) - Capturing group 1: any 0+ chars other than /.
  • $ - end of string anchor. Note that in case you want to make sure the [^\/]* has no / after, add a $ end of string anchor at the end.
