I am trying to define a route in express js that takes an unknown amount N of parameters. It should match the following routes, capturing all digit groups:
/scope
/scope/1/12
/scope/1/12/123
etc.
I wrote a regex for the matching of the n-amount of numbers, as follows:
/(?:\/?(\d+)\/?)/g
The global /g however doesn't seem to be allowed, see (The regex parser of express js on github). Am I doing something wrong here? I could solve this very ugly and dirty by doing something like:
^\/scope\/?(\d+)?\/?(\d+)?\/?(\d+)?
But this is not dynamic, feels dirty and if I add deeper levels of scoping I always will need to add more /?(\d+) regex parts, which is a model that does not fit my business logic. I am shure there must be a better way...
Okay, after a discussion with @vks, which was useful but unfortunately not answering the question, we came to the conclusion that this is not a regex problem. With the \g modifier a regex capturing all digit groups can quite easily be written, even in javascripts very limited regex engine.
The question now becomes more clearly formulated: since expressjs does not allow a full regex from begin to end, but rather encloses the regex you use in a route in it's own begin and end of a regex, not allowing /g modifiers, what is the expressjs idiomatic way to solve this problem?
