In Express.js, how do I set a wildcard route to not match for asset files?

I'm building my first real Express.js app, and stuck on the routing.

I am enabling static hosting:

app.use("/", express.static("public"));

And then I have a wildcard route:

router.get("/:page", function(req, res) {
    // do stuff
});

This route is matching for urls like "/about" and "/contact" - which I want. But it appears that it's also trying to match for "/style.css" and other static asset files - which is unnecessary.

How do I make this wildcard not match for asset files?

if I understand what you want to do ,you should just do something like :

app.js

 app.use(express.static(__dirname + '/public'));
 app.use(express.static(__dirname + '/static'));
 app.use('/:page',function(){}..)

this configuration works when ur public and static folder is relative to app.js, when browser request for static file , first server will look at public folder , if file is no there will continue to static folder and finally to /:page

One solution I found, is to search for a "." inside the query and then set a flag if it's found:

router.get("/:page", function(req, res) {
    if (req.render_view) res.render("index");
});

router.param("page", function(req, res, next, page) {

    // if request is not an asset file      
    if (page.indexOf(".") == -1) {

        // do stuff

        // set a flag
        req.render_view = true;

    }

    next(); 

});

But I would like to find a cleaner solution, possibly using a regular expression in the router.get?
