In this article, we will show you a step-by-step guide to installing and configuring a working React development environment.We will discuss the following approaches to setup environment in React.Table of ContentMethod 1: Using create-react-app (CRA command)Method 2: Using webpack and babelMethod 3: Using Vite build toolPre-requisite:We must have NodeJS installed on our PC. So, the very first step will be to install NodeJS. Once we have set up NodeJS on our PC, the next thing we need to do is set up React Boilerplate.Installation of Node.js on WindowsInstallation of Node.js on LinuxInstallation of Node.js on macMethod 1: Using create-react-app (CRA command)Step 1: Navigate to the folder where you want to create the project and open it in terminalStep 2: In the terminal of the application directory type the following commandnpx create-react-app <<Application_Name>>Step 3: Navigate to the newly created folder using the commandcd <<Application_Name>>Step 4: A default application will be created with the following project structure and dependenciesApplication structureIt will install some packages by default which can be seen in the dependencies in package.json file as follows:"dependencies": { "@testing-library/jest-dom": "^5.17.0", "@testing-library/react": "^13.4.0", "@testing-library/user-event": "^13.5.0", "react": "^18.2.0", "react-dom": "^18.2.0", "react-scripts": "5.0.1", "web-vitals": "^2.1.4"}Step 5: To run this application type the following command in terminalnpm startStep 6: The following output will be displayed in the browserReactJS InstallationYou can modify the application according to your preferences and change the code accordingly.Method 2: Using webpack and babelTo setup a react development environment using webpack and babel is a long process and we have to import each package and create setup files ourselves.We have to create the setup using 'npm init -y' command and then import the necessary packages in the folder and then install react using the command.npm i react react-domTo install the necessary packages in our project use the commandnpm i webpack webpack-cli @babel/core @babel/preset-env@babel/preset-react babel-loader html-webpack-plugin webpack-dev-server --save-devP.S.: This tutorial covers only the steps to install the packages. To understand how to configure these packages refer to the Introduction to babel article. Method 3: Using Vite build toolStep 1: Navigate to the folder where you want to create the project and open it in terminalStep 2: In the terminal of the application directory type the following command.npm create vite@latest <<Application_name>>npm create vite@latestStep 3: Select the React Framework and then variant as JavaScript from options.select javascript variantStep 4: Navigate to the newly created folder using the command.cd <<Application_name>>now, we can see the basic project structure show in below image.project structureStep 5: Use the below command in terminal to install all required dependencies.npm install ORnpm inpm installAfter successfully executing this command we can see a new folder named "node_module" in the project folder which contains all the dependencies.node_modulesStep 6: To run the application use the following command in terminal.npm run devvite+react page Comment More infoAdvertise with us Next Article React JS ReactDOM H harsh.agarwal0 Follow Improve Article Tags : Misc Web Technologies ReactJS ReactJS-Basics Practice Tags : Misc Similar Reads React Tutorial React is a JavaScript Library known for front-end development (or user interface).
