We should pull out categories of a page into an array as part of the new /page/metadata/{title} endpoint.
If we can use a MW API for this, we can make a call directly. Otherwise we should parse the HTML to get at these.

Please no... categories should remain out of the payload of the MCS endpoint. In mobile we only need to show them with a categories button. The HTML for categories can be quite large and is not necessary for an initial view and arguably not needed even for a below the fold view. I'd recommend the creation of a new endpoint for categories if needed for scalability...

Is anything needed here beyond a simple list of categories?
It would be trivially easy to get these directly from the Parsoid HTML with something like
const categoryLinks = doc.querySelectorAll('link[rel="mw:PageProp/Category"]');
return [].map.call(categoryLinks, link => link.getAttribute('href'));Comment Actions
In mobile web, we currently need to know which categories are hidden
We render like so: https://en.m.wikipedia.org/wiki/Barack_Obama?mobileaction=beta#/categories
https://en.m.wikipedia.org/w/api.php?action=query&format=json&prop=categories&titles=Barack%20Obama&clprop=hidden&cllimit=50&formatversion=2
Can we get that information from Parsoid HTML?

Interesting. Parsoid HTML currently doesn't expose hidden categories. I wonder how @ssastry would feel about adding those.
