Get rest of the path from requested route in nodejs

Can you get the rest of the path in node.js from reuqested route using express?

Assuming I have my server on port 8080 and I just visit http://example.com:8080/get/path/to/file

var url = require("url");
app.get("/get/*", function(req, res) {
  console.log(req.path);

  // this will return
  // '/get/path/to/file'

  console.log(url.parse(req.path);

  // this will return
  // protocol: null,
  // slashes: null,
  // auth: null,
  // host: null,
  // port: null,
  // hostname: null,
  // hash: null,
  // search: null,
  // query: null,
  // pathname: '/get/path/to/file',
  // path: '/get/path/to/file',
  // href: '/get/path/to/file' }
});

What I want here is to return path/to/file is there a way to get that? or could it be my app.get() route is wrong here?

I know that there are ways to do it using regex, split, substring and many other ways using plain JavaScript, but just want to see the best way to go for this.

I know this is a really old question, but I will post the answer for anyone searching for this. At the time of writing I am using express 4.18.2. To match the remainder of a route you can actually do something like this:

app.get("/some/url/:pathToFile(*)", (req, res) => {
  const pathToFile = req.params["pathToFile"]; //<- Holds the remainder of the route.
});

So navigating to /some/url/path/to/file will result in the route above being matched and the pathToFile variable will be "path/to/file".

You can find path/to/file in req.params:

When a regular expression is used for the route definition, capture groups are provided in the array using req.params[N], where N is the nth capture group. This rule is applied to unnamed wild-card matches with string routes such as /file/*:

// GET /get/path/to/file
req.params[0]
// => path/to/file
