ParsedMessage

Since Node v9.6.0, http.createServer supports an options argument to override the IncomingMessage and ServerResponse constructed for each request. Pass this class as IncomingMessage and have convenient access to properties provided by url.parse and path.parse:

http.createServer({
    IncomingMessage: require("ParsedMessage")
}, (req, res) => {
    req.path       // url.parse(req.url).path
    req.pathname   // url.parse(req.url).pathname
    req.query      // querystring.parse(url.parse(req.url).query
    req.search     // url.parse(req.url).search
    req.hash       // url.parse(req.url).hash
    req.parsedUrl  // url.parse(req.url)
    req.parsedPath // path.parse(req.pathname)
    req.root       // path.parse(req.pathname).root
    req.dir        // path.parse(req.pathname).dir
    req.base       // path.parse(req.pathname).base
    req.ext        // path.parse(req.pathname).ext
    req.name       // path.parse(req.pathname).name
}))

Check out the source code, it's very simple. I cache the result of url.parse so it's only called once, and only once you use one of the shortcuts.
