node.js - Express-js wildcard routing to cover everything under and including a path

Question

I'm trying to have one route cover everything under /foo including /foo itself. I've tried using /foo* which work for everything except it doesn't match /foo. Observe:

var express = require("express"),
    app = express.createServer();

app.get("/foo*", function(req, res, next){
  res.write("Foo*
");
  next();
});

app.get("/foo", function(req, res){
  res.end("Foo
");
});

app.get("/foo/bar", function(req, res){
  res.end("Foo Bar
");
});

app.listen(3000);

Outputs:

$ curl localhost:3000/foo
Foo
$ curl localhost:3000/foo/bar
Foo*
Foo Bar

What are my options? The best I've come up with is to route /fo* which of course isn't very optimal as it would match way too much.

I think you will have to have 2 routes. If you look at line 331 of the connect router the * in a path is replaced with .+ so will match 1 or more characters.

If you have 2 routes that perform the same action you can do the following to keep it DRY.

var express = require("express"),
    app = express.createServer();

function fooRoute(req, res, next) {
  res.end("Foo Route
");
}

app.get("/foo*", fooRoute);
app.get("/foo", fooRoute);

app.listen(3000);
