SUPPORTSProblem

I'm building a Next.js 14 app that uses Zustand with the persist middleware to store authentication tokens and user info. Tension: authenticated pages redirect me to /error/unauthorized. Outcome: React has detected a change in the order of Hooks...

RELATES_TOSolution

Use import("zustand").UseBoundStore in the JSDoc type for the bound store

REQUIRESSolution

Use Zustand’s recommended store context provider pattern so the store can be created after props/data are available. In the provider, fetch API data in a useEffect, then initialize the store (via a ref) with the fetched results, ensuring components only access the store after it’s created.

REQUIRESSolution

Update the store slice directly without the functional `set` callback, e.g. `set({ storagePolicySettings })` instead of spreading and returning a new state object.

REQUIRESSolution

Use import("zustand").UseBoundStore in the JSDoc type for the bound store

REQUIRESSolution

Create a custom Zustand middleware that wraps the store’s `set` function and, on every state update, merges in `lastModifiedAt: Date.now()` when the state being set includes or is compatible with that field.

REQUIRESSolution

Properly mock the Zustand store module by spying on/overriding the store export (the Zustand `create` result or the correct store factory export) to return a custom state and action implementation, then render the component and assert against the mocked behavior.

REQUIRESSolution

const useMulti = ( useStoreFn: UseBoundStore>, ...items: K[] ): Pick => useStoreFn((state) => Object.fromEntries(items.map((item) => [item, state[item]])) as Pick ) — wrapper hook for `useStore`. Outcome: const useStoreState = (...items: Array) => useMulti(useStore, ...items).

REQUIRESSolution

Treat the selected value as a shared reference (avoid unnecessary cloning/deriving new arrays/objects in selectors). If memory pressure occurs, ensure large datasets are not being copied or accidentally retained (e.g., avoid creating new Float32Array/object instances per render; consider weak caching patterns such as WeakMap only for derived mappings).

REQUIRESSolution

found it pretty awesome, but was stuck on the same question — The problem is in the comparison function. Tension: two objects are being compared (which won't return true on the comparison and thus always update). Outcome: import shallow from 'zustand/shallow'.

REQUIRESSolution

Create/move the React.lazy import initialization so it isn’t executed on every render (e.g., place the lazy call in the same component as Suspense) to ensure the import is stable and doesn’t trigger repeated re-renders.

REQUIRESSolution

an alternative approach could be to use a global store, such as zustand — once the Tiptap extension is initialized. Tension: it's not going to react to prop changes. Outcome: Here's an example from an implementation that I'm using:.

PERTAIN_TOSolution

Make both select inputs controlled components by binding their value to the zustand language state (using `value={language}`) and updating the store on change via the store `set`/action, so both selects re-render and stay in sync.

PERTAIN_TOProblem

A TypeScript error occurs when using Zustand's persist middleware with a custom StateCreator, stating that a StateCreator argument is not assignable to the expected StateCreator type due to mismatched $$storeMutators typing.

PERTAIN_TOSolution

const usePermissionsStoreAsync = hook(usePermissionsStore, /*suspense*/false); — const YourComponent = () => {. Tension: if (userPermissions.isLoading) { return Loading... ; } if (userPermissions.error) { return An error occurred ; }. Outcome: Try Leo Query. It handle's async data for Zustand.

PERTAIN_TORootCause

doing `export * from` only re-exports named exports. Tension: neither default export from vanilla nor react would be re-exported here. Outcome: Without lines 3 and 4, the above would not occur.

PERTAIN_TOSolution

To import vanilla's default export, you'd need to do.

PERTAIN_TOProblem

can't for the life of me get the typing to work out correctly — create a wrapper hook for `useStore` that will just take a list of keys. Tension: Zustand's types are pretty complicated and do a lot of inference.

PERTAIN_TOSolution

Use the event value directly for the network call (e.g., `event.value`) or move the dependent side effect to a store subscription/`useEffect` that runs after `sortBy` updates.

OCCURS_INProblem

After migrating to React 18, dynamically importing a language-specific component with React.lazy based on a zustand state variable causes the component to infinitely render/loading.

ENRICHESPackage

create

AFFECTSRootCause

const useTodoStore = create((set) => ({ — handleAddItem: (title) => {. Tension: const newId = Math.max(...set.getState().toDoList.map((todo) => todo.id)) + 1;. Outcome: use get().item in case of fetching state instead of set.getState().item.

AFFECTSRootCause

The setters you're providing from your store, only accept regular values and not updater functions too. — Tanstack react-table expects a function for controlling the change handlers which accept both a value and an updater. Tension: think of React's useState api.

AFFECTSRootCause

The selector subscribes to `state.nestedObject.name`, but with Immer the selector equality/subscribe behavior prevents a re-render when only a nested property changes. Without proper equality handling, Zustand may not detect the change for the selected value.

AFFECTSRootCause

A globally instantiated Zustand store is reused across requests in a server environment, so multiple simultaneous requests may read/write the same state. This violates Next.js guidance that requires per-request store instances to avoid cross-request state leakage.

AFFECTSRootCause

await fetchUserPermissionss(id); const districtsData = [...new Set(**test**.map((item) => item.district_id))];. Outcome: Try Leo Query. It handle's async data for Zustand.

AFFECTSRootCause

https://docs.pmnd.rs/zustand/guides/slices-pattern. Tension: however for some reason I get some errors.

AFFECTSRootCause

The event handlers capture an outdated `sequence` value from the initial render; when sequence updates occur (especially within pointer lifecycle events), the handlers continue referencing the stale closure. Recreating handlers within handlers still preserves the original stale closure because updates are not synchronized with the event callback timing.

AFFECTSRootCause

The code reads `retry_n` once via `retryStore.getState().retry_n` outside the loop, so it repeatedly computes `retry_n + 1` from a stale value. Additionally, using `setState` directly with a captured value prevents the state from being derived from the latest store state.

AFFECTSRootCause

Using `set` with incorrect references (e.g., `state.uid` inside a setter defined without proper state/input) and not directly setting `user` from the Firebase payload leads to wrong or incomplete state updates.

AFFECTSRootCause

console.log(sortBy) // this is the zustand state variable that is in scope — setSort(event.value). Tension: I expect these would be the same, but they aren't! Outcome: console.log(store.getState().sortBy) // event.value == sortBy.
