Question

I want to set up some more complex routes that can include a number of optional parameters. Preferably, I would like to use named parameters for ease of access. Here is an examp

It looks like you want to re-implement the query string using the URL path. My guess is that if you really wanted that, yes, you would have to write your own parsing/interpreting logic. AFAIK express path parameters are positional, whereas the query string is not. Just use a query string and express will parse it for you automatically.

/books?category=sports&author=jack&limit=15?sortby=title

That will enable you to do

req.query.sortby

You may be able to get express to do 1/2 of the parsing for you with a regular expression path like (:key/:value)* or something along those lines (that will match multiple key/value pairs), but express isn't going to then further parse those results for you.
