Redux is a predictable state container for JavaScript apps, widely used in the React ecosystem. It helps manage the state of your application in a centralized and predictable way.

Key Concepts

  • Actions: Actions are payloads that carry information. They are the only way to communicate to the store.
  • Reducers: Reducers are functions that specify how the application's state changes in response to actions.
  • Store: The store is the single source of truth for all the data in your app. It holds the whole state tree of your app.

Getting Started

To get started with Redux, you can use the following steps:

  1. Install Redux: You can install Redux using npm or yarn.

    npm install redux
    

    or

    yarn add redux
    
  2. Create the Store: Create a Redux store with your root reducer.

    import { createStore } from 'redux';
    
    const store = createStore(rootReducer);
    
  3. Connect React with Redux: Use react-redux to connect React components to the Redux store.

    npm install react-redux
    
  4. Use the Provider Component: Wrap your app with the Provider component and pass the store to it.

    import { Provider } from 'react-redux';
    import store from './store';
    
    const App = () => {
      return (
        <Provider store={store}>
          <YourApp />
        </Provider>
      );
    };
    
  5. Dispatch Actions: Dispatch actions from your components to update the store.

    import { useDispatch } from 'react-redux';
    import { increment } from './actions';
    
    const Counter = () => {
      const dispatch = useDispatch();
    
      return (
        <button onClick={() => dispatch(increment())}>
          Increment
        </button>
      );
    };
