State sharing in different RecoilRoot components

[daliusd]

We have situation where we need to share state between different RecoilRoot components. I have not found a way to do that via API so I assume it is not possible to do that. Maybe it would be possible to add argument allowing passing state's instance to RecoilRoot component?

Can you provide more details on why you need to share state between different RecoilRoot components, rather than using one RecoilRoot to wrap them all?

[daliusd]

We need to share state between different applications (old project gradually moving to React). There is no way to wrap everything under single RecoilRoot.

E.g. with Redux we can pass store instance to redux Provider components so it would be good if that were possible with Recoil as well.

@drarmstr is this possible yet?

Is this possible using an observer and passing the state setting function in from within the other recoil root?

It is probable that solution to #140 might solve this problem as well. IMHO you can mark this as duplicate of #140 now. In case solution to #140 will not be enough then I or someone else can reopen this issue.
