Redux Tutorial

Welcome to the Redux tutorial! Redux is a predictable state container for JavaScript apps, often used with React. It helps you manage the state of your application in a centralized way, making it easier to debug and maintain.

Basics of Redux

State Container: Redux acts as a single source of truth for all the data in your application.
Actions: Actions are payloads of information that send data from your application to your store.
Reducers: Reducers are functions that specify how the application's state changes in response to actions.

Install Redux

Before you start, make sure you have Node.js installed. Then, use npm to install Redux:

npm install redux

Example

Here's a simple example of a Redux application:

// Store
const store = createStore(reducer);

// Action
const increment = { type: 'INCREMENT' };

// Reducer
const reducer = (state = 0, action) => {
  switch (action.type) {
    case 'INCREMENT':
      return state + 1;
    default:
      return state;
  }
};
