Feature request: Initialize StoreProvider with defaultState

[Christopher96u]

I'm trying to implement something like this library: https://github.com/charkour/zustand-di

I'm using the utility helper from this library(zustand-slices) to create the Provider, but I'm still dealing with the TS Type inference to make it type-safe.

Could you provide a example of this feature?

It's really helpful for testing. I don't wanna use stores without Provider because it's really hard to test.

Any idea?

I want to get the Provider like this

<GlobalStoreProvider defaultState={initialState}>
where initialState infers the type based on my store, thanks!

If I understand it correctly, the question is about how to type React Context, which is not specific to Zustand.

How does zustand-di solve it?

Please try to create a very very small example to illustrate what you would like to accomplish with https://www.typescriptlang.org/play.

Hi, a bit busy with my little one today. I'll make a demo tonight and share it with you. Thanks

Hi @dai-shi , I've written an example and added some comments. example

I'm open to any suggestion. I feel adding the ability to define the zustand context with a prop initialState would be helpful for testing and test components in a isolated way. I'm doing this workaround because I have the same tradeoff than the blogger from here blog . Initialize the store with context will save lot of effors. If not, any advice? The Zustand official documentation for testing, doesn't explain it very well. Thanks

Unfortunately, the example doesn't help me understand the problem. Is it modified after you created?

I have a few comments:

• What you request should be possible on your end. You can use Context and zustand-slices and create store using props.
• If your question isn't tied to zustand-slices, you might want to open a discussion in the zustand repo. More people will look
• In general, it's not certain if using Context only for testing is ideal. I would avoid adding code in production which is only required for testing.
