To know more about Node.js check . here What is ReactJS? As I’ve noticed earlier, React is based on using components. Components allow you to split the UI into independent reusable pieces and think about each piece in isolation. You can find many sources about components creating including . If you take a look at the examples you will see the funny mix of JS and HTML. It’s called (Javascript XML). So if you want to learn React you should know about both of them. official React docs JSX Popular React libraries The template from this article is built with tool and libraries and . Create-React-App React-router Redux Create-React-App Create-React-App is a boilerplate provided by Facebook for almost any React project. It has a ready project structure, base setup and dependencies for a quick start. It’s created by developers of React and constantly updated. React Router React-router is a library that allows you to build SPA routing within your web app in the easiest way. What it means — you can swap pages (components) in real time without page reloading by using simple components. Each route renders its respective component when its path matches the URL. Also, you can find a router which allows you to change a page’s content without refreshing. Thanks to it you get a Single Page Application (SPA). React Router allows you to add new pages to your app easily. In the template you can just add new Route in : '~/easydevseed/src/containers/App/Router.jsx' import LogIn from '../LogIn/index';... Now you can add to URL and see your page. That’s easy, isn’t it? '/login' Then you can go to Redux. Redux Redux is a tool for managing both data-state and UI-state in React applications. It’s perfect for SPAs where state growing with new features, becoming more and more complicated. It is more complex than the libraries before, but it’s very useful for data managing. Redux works this way: The only way to trigger a state change is to call . It dispatches an action. For example, we can change sidebar state: dispatch(action) changeSidebarVisibility = () => { this.props.dispatch(changeSidebarVisibility());}; Action makes a request and gets a current data. Its return value will be considered as the next state. Actions must have a property that indicates the type of action being performed. Types should typically be defined as string constants. There is the action that is triggered in dispatch above: “type” export const CANGE_SIDEBAR_VISIBILITY='CANGE_SIDEBAR_VISIBILITY'; export function changeSidebasVisibility() { return { type: CANGE_SIDEBAR_VISIBILITY, };} Action returns an object that contains required data and field which represents part of reducer to be used (matched by name). Dispatch sends returned object to the reducer. The reducer decides how to change redux state according to data in the action object. In the example, you can see that our action returns type, but no value. Reducer accepts our action, finds a case in switch and updates state. It takes the old state as it and reverses collapse value. “type” const initialState = {show: false,collapse: false,}; export default function (state = initialState, action) {switch (action.type) {case CHANGE_SIDEBAR_VISIBILITY:return { ...state, collapse: !state.collapse };case CHANGE_MOBILE_SIDEBAR_VISIBILITY:return { ...state, show: !state.show };default:return state;}} New data is caught by connecting function in the component which extracts required data and returns it to props. React handles data change and re-renders an app with new data. export default connect(state=> ({sidebar: state.sidebar,}))(Layout); The code above allows changing the sidebar state from any part of the app. Depending on the value in the state, the sidebar class will change: const Sidebar = ({ return ( );}; And this will change component styles: Here you can see the new style of the sidebar. Code linting A code quality is one of the important things of any project. ESLint is good for improving a project code style. It’s the pluggable linting utility for JavaScript and JSX. It allows you to write a code in the same style thanks to highlighting formatting errors. This is especially helpful when you work with a team. You can write some rules in . and your code gets more attractive and readable. eslintrc Project build When you finished your project you need to deploy it. Just run the command or to build project to the folder. It correctly bundles React in production mode and optimizes the build for the best performance. Your app is ready to be deployed! “npm run build” “yarn build” ‘build’ Conclusion The template from this article helps you to start your way in ReactJS.
