Sub-Folder style routing in Express

Question

I want to parse simple routes like these:

http://example.com/foo/bar/baz/

where there is no theoretical limitation to the number of them. And it would be nice to have an array ['foo','bar','baz'] from it.

How to do it with Express routing?

Answer 1

Use a regular expression.

app.get(/^\/((?:[^\/]+\/?)+)\//, function(req, res) {
  res.send(req.params[0].split('/'));
});

app.listen(8080);

Run it and then

$ curl localhost:8080/foo/bar/baz/
["foo","bar","baz"]
