redux - NPM Package

Redux is a popular state management library that is commonly used in React applications to manage complex state across components. When you work with Redux, npm (Node Package Manager) plays an integral role in managing the Redux packages and other related dependencies in your project.

In this article, we’ll explore how to use npm with Redux in a React project.

What is Redux?

Redux is a predictable state container for JavaScript applications. It helps manage the state of your application in a single, centralized store, making it easier to handle complex state changes, especially in larger applications. Redux can be used with any JavaScript framework, but it’s most commonly associated with React.

Core Principles of Redux

• Single Source of Truth: The state of your entire application is stored in one centralized object tree, known as the store.
• State is Read-Only: The only way to change the state is by dispatching an action, which is a plain object that describes what happened.
• Changes are Made with Pure Functions: Reducers are pure functions that take the current state and an action, and return a new state based on the action.

Setting Up Redux with npm

To start using Redux, you'll need to install it and related packages using npm. Below is a step-by-step guide on how to set up Redux in a React project.

Step 1: Create a React Project

If you don’t have a React project set up already, you can create one using npx and create-react-app:

npx create-react-app my-redux-app
cd my-redux-app
npm start

This will create a new React project and start the development server. You can now integrate Redux into this project.

Step 2: Installing Redux and Related Packages

To use Redux with React, you need to install two main packages:

1. redux: The core Redux library.
2. react-redux: A library that provides React bindings for Redux, enabling your React components to interact with the Redux store.

You can install both of these packages using npm:

npm install redux react-redux

This command installs both Redux and React-Redux into your project and adds them to your package.json under dependencies.
