Limited documentation on array keys & pagination

[colinhacks]

Having read the full docs, I'm still confused about the behavior when using array keys.

• If any of the items in the array key are null, does SWR cancel the request?
• Do all items have to be strings? Another discussion seemed to imply that. If so, why isn't that enforced by the TypeScript typings?
• Pagination is listed as a feature but not documented at all?

I appreciate any help/clarification here.

1. No, swr will still fire the request

const { data } = useSWR(['/api', null], (...args) => {
  console.log(...args) // api null
})

2. items in the array key could be object. But swr shallowly compares (===) the arguments on every render, and triggers revalidation if any of them has changed. Arguments
3. The docs does have a section about Pagination

Ah thanks! I didn't know there was additional documentation at swr.vercel.com. Seems like they tried to add all the docs into the README and gave up at some point. Strange.

Thanks for your help!
