style=\"font-weight: 400;\">The first step in getting hands-on experience in ReactJS&nbsp; and creating a React project is installing ReactJS in your system with<\/span><strong><a

400;\">. This can be done using your in-built terminal or you can download one that you prefer. There is a prerequisite to have<\/span><strong><a href=\"https:\/\/nodejs.org\/en\/download\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"> Node.js<\/a><\/strong><span style=\"font-weight: 400;\"> pre-installed on your PC, with NPM in it, for this installation to run smoothly.&nbsp;<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Confirm that you have Node and NPM installed on your PC by typing <\/span><b>node -v<\/b><span style=\"font-weight: 400;\"> and then <\/span><b>npm -v<\/b><span style=\"font-weight: 400;\"> in your terminal\/command prompt.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Because create-react-app requires that you have<\/span><strong><a href=\"https:\/\/github.com\/npm\/npm\/releases\/tag\/v5.2.0\" target=\"_blank\" rel=\"noreferrer noopener nofollow\"> NPX<\/a><\/strong><span style=\"font-weight: 400;\"> installed, you&#8217;ll need to make sure your Node version must not be older than v14.0.0 and NPM version, no older than v5.6.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Now install React with create-react-app.<\/span><\/p>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"Why_use_the_Create-react-app\"><\/span><b>Why use the Create-react-app?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">This is a common question. Although we can create a new ReactJS application manually, this process is cumbersome and time-consuming. The create-react-app makes the installation process much easier by automating the entire configuration and package installation.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">You can easily build a new single-page application in React using the create-react-app.&nbsp;<\/span><\/p>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"How_to_Create_a_React_Application\"><\/span><b>How to Create a React Application<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">In your command prompt\/terminal, navigate to the folder where you wish to save your new React application (here we are naming the application as my-first-app; you can use any name of your choice.) Execute the following command:<\/span><\/p>\n\n\n\n<p><b>npx create-react-app my-first-app<\/b><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">The installation process will take a few minutes to complete, after which, a folder will appear in your workspace with the name \u2018my-first-app\u2019. Congratulations! You have created your first React application.<\/span><\/p>\n\n\n\n<h3><span class=\"ez-toc-section\" id=\"How_to_Run_Your_React_Application\"><\/span><b>How to Run Your React Application<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">In the terminal, type cd my-app to navigate to the folder in which the React app was created.

Make sure that the course helps you gain an in-depth knowledge of various concepts such as Node Packet Manager (NPM), Express.js, REST, Express.js, shrink-wrap, NPM Vet, along with MongoDB, and SQLite CRUD operations. Your Node JS training should focus on the essential Node JS concepts and provide hands-on experience in important tasks like building an HTTP server.&nbsp;<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Wish you all the best in your ReactJS developer journey!<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>In the last few years, ReactJS has emerged as the most sought after tool for<\/p>\n","protected":false},"author":1,"featured_media":4382,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[219],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v15.3 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>A Beginner&#039;s Guide To Become React Js Developer<\/title>\n<meta name=\"description\" content=\"In the last few years, ReactJS has emerged as the most sought after tool for front-end web development.
