I can't create a route path with optionals strings and parameters - ExpressJS

Question

I want to be able to write a route in the following ways (I have 3 parameters: lapsnumber, time and breaktime):

/20minutes
/1laps-20minutes-10secondsbreak
/2laps-20minutes

My current code is this one:

router.get('/(:lapsnumber-)?:time(-:breaktime)?', function(req,res,next) {
  res.render('timer', {
    lap: req.params.lapsnumber,
    time: req.params.time,
    breaks: req.params.breaktime
  });
})

How can I do that? Thank you so much! :)
