Batched updates

[huczk]

Zustand is great, but it does not currently support one feature that would help me a lot - batch updates. Batch updates are useful when multiple state changes need to be made within a single action or event.

One approach to adding batch update support is to add a new method to the store object, such as batchUpdate(), that accepts a callback function. This function would contain all the state updates that need to be made, and Zustand would ensure that they are all executed together as a single atomic transaction or pause listeners and trigger them after batchUpdate will finish. Another approach would be to add a middleware.

We made a decision to rely on React for batching. It should cover most cases.
If you need batching, please feel free to create a third-party library to provide a util function or a middleware.

Middleware can do anything. (Even a util can mutate store API.)

I would do a simpler solution.

const useFooStore = create((set) => ...)
const batchUpdateFooStore = (callback) => ...
// usage
batchUpdateFooStore((set) => ...)

Anyway, there can be many solutions. Hope you find something you like.
Feel free to let me know if you need more help.

hi, more than a year has passed, is there any progress

[huczk]

I ended up with forking the package, and added function batch(callback: () => void) which block listeners calling until callback finish

This is exactly what I am looking for while working on my gps tracking solution. Need to send many state updates as one as a result of an event.
