Workbox: writing regular expression for url patterns

I am trying to precache routes. I have successfully precaches the homepage using

 workbox.precaching.precacheAndRoute(['/']);

and this to match route for homepage

workbox.routing.registerRoute(
 /^\/$/,
  new workbox.strategies.NetworkFirst({
    cacheName: 'static-resources',
  })
);

I still have other top level routes i will like to match but not sure how.

localhost/subcategory //subcategory and slug attached to it
localhost/product  //product and slug attached to it
localhost/product-single // and slug attached to it

How do i write the regular expression for the above

    A regex like ^localhost(\/.+)?$ should do the trick
