The path core module gives you the tools to deal with this. So, just put this logic in a middleware before your static middleware, like:

var express = require("express"); var path = require("path");  var app = express(); var port = 8181;  app.use(function (req, res, next) {     var filename = path.basename(req.url);     var extension = path.extname(filename);     if (extension === '.css')         console.log("The file " + filename + " was requested.");     next(); }); app.use(express.static(__dirname));  app.listen(port);
