[v2] Support for Emotion 10

[aaronjensen]

react-select appears to depend on emotion 9. Similar to #3120, if I'm using a newer version of emotion (like 10) I'll have 2 versions of emotion at best (if it works). At the moment I'm running into typing errors between the two, but ideally we could upgrade react-select to emotion 10. If you're up for a PR doing this, I may have some time to pull that together.

Cheers!

That would also fix SSR issues for Next.js users without needing to set up the whole emotion-server infrastructure.

@aaronjensen thanks for raising the issue, this is something we have on our roadmap but haven't yet gotten to. If you still have the time, a PR to upgrade to emotion 10 would be greatly appreciated 👍

@gwyneplaine it looks like this was actually done and released here already: 4bad8b8

@aaronjensen Thanks for the reply but I don't see it released on latest (2.4.2). I also don't see an alpha release. This issue should be open until it is released.

@andrerpena when I wrote this, I believe 2.2.0 was the latest version and it was using create-emotion 10 and not depending on emotion at all: https://unpkg.com/react-select@2.2.0/package.json

We used it successfully w/ emotion 10 on my last project. Since it appears this was undone 214a161 I'll reopen.

Thank you so much @aaronjensen. This is important to unlock Next.js users

Hi all, for context, the upgrade to create-emotion 10 doesn't unlock zero-configuration SSR, actually it makes ssr more difficult as the same custom emotion instance needs to be passed to both the client side and server-side select. The work in #3260 didn't allow for an easy way to do that at all, at least not without making compromises to our API that would tightly couple react-select with emotion.

This is the primary reasoning behind the reversion in 2.3.0. For more details about this please see #3317 and #3346.

I'm looking to release 3.0.0 with an upgrade to emotion 10 with a NonceProvider export which should both unblock CSP users and enable true zero-config SSR, you can see the details of that pr here #3321.

@gwyneplaine That would be amazing! The Next.js community is growing rapidly and would love to use react-select!
