Ok, for HTTP request pathname matching you can just use express. I'm
pretty sure it allows this kind of pattern matching our of the box. To
implement such matching yourself it easy.
var http = require('http');
var url = require('url');
// Match /some/folder/:id/*
var pattern = new RegExp("^/some/folder/([^/]+)(.*)$");
http.createServer(function (req, res) {
// pathname removes trailing query strings and gives just the path
var pathname = url.parse(req.url).pathname;
var match = pathname.match(pattern);
if (match) {
// the request matched
// :id is in match[1] and anything after it is in match[2];
}
})
What most frameworks will do is take your string like
"/foo/bar/:param1/:param2" and compile it into a custom regular expression
and then match on that.
