Hi Clifford,
First, br/resource-maybe can only appear as the second item of a route
pair, because it only satisfies the bidi.bidi/Matched protocol. The first
item of a route pair is for patterns only, i.e. types that satisfy
bidi.bidi/Pattern protocol.
What you are trying to do is easy (when you know how).
Let's assume you have a file in your project resources/public/foo.txt such
that
(io/resource "public/foo.txt")
returns non-nil
Your route structure could look like this :-
(def routes
["" [
["/index.html" :index]
["" (br/resources {:prefix "public"})]
]])
Note here I'm using a *vector-of-vectors* syntax, which I recommend when
you have ambiguous patterns because the order in which the patterns should
be tried is made explicit. (You can use maps, but I suggest using the more
verbose vector-of-vectors syntax in cases such as this)
(bidi/match-route routes "/index.html") => {:handler :index}
as we should expect.
(bidi/match-route routes "/foo.txt")
will try fail the "/index.html" pattern, and try the "" pattern with a
remainder of "/foo.txt". The prefix of "public" is then preprending,
resulting in the string "public/foo.txt", which is passed to io/resource -
and we get a hit.
The difference between resources and resources-maybe, is that resources
will always return a handler - if the resource doesn't exist the handler
will return {:status 404} - no other patterns will be tried. If you use
resources-maybe, then a nil is returned if there is no matching resource,
and any remaining patterns are then tried.
I hope this helps - let me know if you need more help.
Regards,
Malcolm
