Multiple API requests are fired when increasing the page size of useSWRInfinite

[crushjz]

Bug report

Description / Observed Behavior

The useSWRInfinite hook fires a double request every time there is a setSize(size + 1) call.

This only happens in SWR version 1.x. Everything works fine with version 0.x.

Expected Behavior

There should only be 1 request per setSize call.

Repro Steps / Code Example

This is the official example found in the pagination documentation. It uses SWR 0.3:

https://codesandbox.io/s/swr-infinite-z6r0r?from-embed=&file=/src/App.js

This is the exact same example, but uses SWR 1.0.1:

https://codesandbox.io/s/swr-infinite-1-0-double-api-call-issue-fbvzs

If you open the network tab, you will see multiple request fired every time you click "load more" .

Additional Context

SWR version: 1.x

I just encountered this exact issue right now and it seems to happen exclusively on 1.x

[crushjz]

Given #1401, I think this is an expected behavior and the issue can be closed.

As @shuding said there, the solution is:

There is now a revalidateFirstPage option in swr@beta 🎉
