Express Routing: multiple URLs to the same route

Question

I'm trying to make the multiple URLs work on a single express route. How can I make the following URLs all route to the same page?

• https://example.com/page-slug-name
• https://example.com/page-slug-name/amp
• https://example.com
• https://example.com/amp

It seems like this should work but it's not:

router.get("/:slug?(/amp)?", function(req, res, next) {

  if (!req.params.slug) {
    req.params.slug = 'home'
  }

  getData(slug, function(err, data){

    res.render('index', data)

  });

});

You can have it in single express route by placing multiple URLS inside an array. In your case, this will be

  app.get(['/', '/:slug', '/amp', '/:slug/amp'], function(req, res, next) {
    if (!req.params.slug)
      req.params.slug = 'home'
    getData(slug, function(err, data){
      res.render('index', data)
    });
  );
