Fixing bug of React article




State management is a crucial aspect of developing React applications, especially as your application grows in complexity. While React has its own built-in state management system, there are many third-party libraries and tools available to make state management more efficient and scalable. One such library is Zustand, a lightweight and flexible state management solution. In this article, we will explore how to implement Zustand in a React.js application with code snippets.

What is Zustand?

Zustand is a minimalistic and simple state management library for React. It is designed to provide a way to manage the global state without much boilerplate code. Zustand's key features include a minimal API surface, the use of hooks for state management, and a small bundle size. It's a great choice for applications of various sizes, from small projects to large-scale applications.

Setting Up a React Application

Before we dive into Zustand, you need to set up a basic React application. If you don't have one already, you can create a new React application using Create React App:

npx create-react-app zustand-example
cd zustand-example
npm start

Installing Zustand

You can install Zustand via npm or yarn.

npm install zustand
# or
yarn add zustand

Creating a Zustand Store

Zustand stores are where you define and manage your application's state. Let's create a simple store for managing a counter in your application.

In a new file, such as counterStore.js, define your store:

import create from 'zustand';

const useCounterStore = create((set) => ({
  count: 0,
  increment: () => set((state) => ({ count: state.count + 1 })),
  decrement: () => set((state) => ({ count: state.count - 1 })),

export default useCounterStore;

In this example, we use the create function from Zustand to create a store for managing a counter. The store includes the initial state of count and two functions to increment and decrement the counter.

Using Zustand in a React Component

Now that you have created a Zustand store, you can use it in your React components. Let's create a simple counter component that interacts with the useCounterStore:

import React from 'react';
import useCounterStore from './counterStore';

function Counter() {
  const { count, increment, decrement } = useCounterStore();

  return (
      <p>Count: {count}</p>IncrementDecrement

export default Counter;

Here, you import the useCounterStore hook and use it to access the count state and the increment and decrement functions from the store.

Consuming the Store in Other Components

To consume the same store in other components, you can import and use the useCounterStore hook in those components. This allows you to access the shared state across your application.

import React from 'react';
import useCounterStore from './counterStore';

function AnotherComponent() {
  const { count } = useCounterStore();

  return (
      <p>Count in AnotherComponent: {count}</p>

export default AnotherComponent;

By using the same useCounterStore hook, both components will have access to and update the same state.


Zustand is a lightweight, easy-to-use state management library for React applications. It simplifies global state management by using hooks and providing a minimal API surface. With Zustand, you can easily create and share states across different components in your application. This article provides a basic introduction to implementing Zustand in a React application, and you can expand on these concepts to build more complex state management solutions.
