storeGalleta is a Zustand store created with create that holds the state for a simple cookie (“galleta”) demo used in the Zustand concept page of Fundamentos React. It stores a single detalle object describing a cookie by its nombre (name) and tipo (type), and exposes one action — setGalleta — that replaces the entire detalle object with a new value. Because the store is defined at module level, any component in the application can subscribe to it and dispatch updates without wrapping the tree in a context provider.

​
Import

import storeGalleta from '../context/storeGalleta'

​
Store shape

​
detalle
object
The currently stored cookie descriptor. Contains two string fields:
  • nombre string — The cookie’s name. Initial value: 'Nucita'.
  • tipo string — The cookie’s type or category. Initial value: 'galleta'.
Initial value of the full object: { nombre: 'Nucita', tipo: 'galleta' }.
​
setGalleta
function
Action that replaces detalle with a new object. Accepts a single argument — a plain object with nombre and tipo string properties — and calls Zustand’s set to update the store.Signature: (newGalleta: { nombre: string; tipo: string }) => void

​
Full source

import { create } from "zustand";


const storeGalleta = create((set)=>({
    
    detalle:{
        nombre: "Nucita",
        tipo: "galleta",
    },
    
    setGalleta: (newGalleta) => set({ detalle: newGalleta })
    
}))


export default storeGalleta

​
Usage

Call storeGalleta() inside any functional component to destructure the state and action you need. Zustand re-renders only the components that subscribe to the slice of state they use. 
const { detalle, setGalleta } = storeGalleta()

// read
console.log(detalle.nombre) // 'Nucita'

// update
setGalleta({ nombre: 'BIMBO', tipo: 'Ponkey' })
Because Zustand stores are module-level singletons, storeGalleta does not require a <Provider> wrapper anywhere in the component tree. Simply import the store and call it as a hook from any component — reads and writes are automatically shared across all subscribers.
