What is Redux and how to integrate it with React.js on Vultr?

Redux is a JavaScript library that helps in managing the state of your application. It provides a predictable state container, making it easier to manage and update data in a predictable manner. It is commonly used with React.js to control the application's state.

To integrate Redux with React.js on Vultr, follow these steps:

1. Create a new React.js project on Vultr. You can do this by logging into your Vultr account, selecting the desired server, and installing Node.js and npm.
2. Install Redux and React Redux packages in your project. Open a terminal or command prompt and navigate to the root folder of your project. Run the following command: npm install redux react-redux
3. Create a new folder called redux in the src directory of your project. Inside the redux folder, create the following files: actions.js: Define your Redux actions here. reducers.js: Define your Redux reducers here. store.js: Create and export your Redux store configuration here.
4. In actions.js, define your Redux actions using the createAction function from the Redux library. For example: import { createAction } from 'redux'; export const incrementCounter = createAction('INCREMENT_COUNTER'); export const decrementCounter = createAction('DECREMENT_COUNTER');
5. In reducers.js, write the Redux reducers that will handle the state updates for your actions. For example: import { createReducer } from 'redux'; const initialState = { counter: 0, }; export const counterReducer = createReducer(initialState, { INCREMENT_COUNTER: (state) => ({ ...state, counter: state.counter + 1 }), DECREMENT_COUNTER: (state) => ({ ...state, counter: state.counter - 1 }), });
6. In store.js, create and export your Redux store by combining the reducers. For example: import { createStore, combineReducers } from 'redux'; import { counterReducer } from './reducers'; const rootReducer = combineReducers({ counter: counterReducer, }); const store = createStore(rootReducer); export default store;
7. In your main index.js file, import the Provider component from the react-redux package and wrap your app with it. Pass the Redux store as a prop. For example: import React from 'react'; import ReactDOM from 'react-dom'; import { Provider } from 'react-redux'; import store from './redux/store'; import App from './App'; ReactDOM.render( , document.getElementById('root') );
8. To access and update the Redux state in your React components, you can use the useSelector and useDispatch hooks from react-redux. Import these hooks and use them in your components. For example: import React from 'react'; import { useSelector, useDispatch } from 'react-redux'; import { incrementCounter, decrementCounter } from './redux/actions'; const Counter = () => { const counter = useSelector((state) => state.counter); const dispatch = useDispatch(); const handleIncrement = () => { dispatch(incrementCounter()); }; const handleDecrement = () => { dispatch(decrementCounter()); }; return (

   Counter: {counter}

   IncrementDecrement
   ); }; export default Counter;

That's it! Your React.js application is now integrated with Redux on Vultr. You can use Redux actions and reducers to control your application's state.

How to create a new React.js project on Vultr?
