Node.js – Express.js routing: optional splat param

expressnode.js

I have a route that looks like this:

app.all('/path/:namedParam/*splat?',function(req,res,next){
  if(!req.params.length){
    // do something when there is no splat
  } else {
    // do something with splat
  }
});

however, this doesn't work – if I call path/foo/bar it hits the route, but if I call path/foo, it doesn't.

Is it possible to have an optional splat param, or do I have to use a regex to detect this?

Edit:

to be clearer, here are the requirements I'm trying to achieve:

  • the first and second params are required
  • the first param is static, the second is a named param.
  • any number of optional additional params can be appended and still hit the route.

Best Solution

This works for /path and /path/foo on express 4, note the * before ?.

router.get('/path/:id*?', function(req, res, next) {
    res.render('page', { title: req.params.id });
});
