PERTAIN_TOSolution

Use get() inside the store creator to read current state, and call useCart.getState() only on the store hook instance

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_TOProblem

Repeatedly clicking the remove button causes an item's cart quantity to drop below zero instead of stopping at 1 and then removing the item.

PERTAIN_TOSolution

Clamp the decremented quantity to a minimum of 0 using Math.max(item.quantity - 1, 0), and when quantity reaches the minimum (e.g., 0), remove the item from the cart and ensure visibility/state updates based on the positive quantity.

PERTAIN_TOProblem

The Add to cart button never switches to the quantity (increment/decrement) state and always renders the fallback/false state. The conditional logic meant to detect whether an item is already in the cart fails.

PERTAIN_TOSolution

Add stable `id` fields to the product data (e.g., in `data.json`) so each item has an intrinsic id. Then dispatch/use the item’s existing id so the `id` comparisons correctly detect items already in the cart and conditionally render the quantity controls.
