React is a free JavaScript library used to develop user interfaces for web applications. You must be wondering what is a JavaScript library. JavaScript libraries consist of pre-existing codes written in JavaScript. These codes can be utilised for carrying out commonly occurring tasks in JS.
The React setup is easy, and it also helps web developers avoid the tedious and often redundant process of writing codes from scratch. It is in charge of streamlining the development of intricate and interactive applications by enabling web developers to create reusable UI components.
Web developers often use this framework to develop desktop, mobile, and web apps- which is why, today, we bring you an easy installation guide for getting started with React on your MacOS.
After installing React and starting your journey to build dynamic interfaces, you can further enhance your skills by signing up for the Full Stack Software Development Bootcamp by upGrad and mastering the art that is development!

Installing React on MacOS is simple but comes with a few prerequisites. Here is a checklist you must keep handy before installing React on MacOS:
Before delving deeper into the installation of Node.js and NPM, let us break down what they actually are. Node.js is a cross-platform and open-source JavaScript library that can run web apps outside the client’s browser.
NPM, on the other hand, is the package manager for Node.js and enables open-source web developers to borrow and lend app development packages.
You need to fulfil a few requirements to download Node.js and NPM on your Mac operating system. You must know the nitty-gritty of the terminal application on your Mac. The next thing you will have to do is, install Homebrew on your device to install Node, avoiding security issues.
Now, let’s get started!
-Type node -v on the terminal to check if the latest version of Node has been downloaded to your system.
-Type npm -v to check if the latest version of NPM has been downloaded to your system.
The Create-react is a catalyst when it comes to seamlessly starting React applications on your system. The Create-react app (CRA) automates the process of configuration of files and installation and configuration of build tools. This saves developers a lot of time and effort that they can utilise by focusing on writing codes and building their applications. Here are some of the features of the CRA:
Configuring React manually is a tedious and complicated task. With the help of the Create-react app, you can develop a new React application locally. It automatically handles all the package installations and configuration for us, further simplifying the process.
A few requirements must be fulfilled before installing React using the Create-react app. You must have a Node version of 8.10 and above and an NPM version of 5.6 and above. Check out how you can install React js using the Create-react app npm:
npm install -g create-react-app
This command will install create-react-app on your system, and by using this, you will be able to create new React projects on your system.
The next step is to set up a new React project on MacOS. Here’s how you should go about it:
create-react-app my-app
You may replace ‘my-app’ with the name of your project. For example, ‘myreactproject1’.
The final step is to run the app on your device. Here’s how you will do it:
Cd my-app
Nmp start
This will start the development server and open your project on your browser.
Focus on structuring your React file a certain way for the best outcomes. A simple React folder can be structured in the following manner:
Src directory: The application’s source code is contained in the Src directory. The components
Components directory: Within the src directory, there is the component directory. The component directory stores all the reusable parts that make up the application.
Pages directory: The pages directory has different application pages, each with its own directory.
Index.js file: The component for each page is exported in the index.js file for that page. To create their UI, pages can import components from the components directory.
Utils directory: The programme’s utility files, such as api.js and helpers.js, are located in the utils directory.
Assets directory: The assets directory stores pictures, font files, and everything that does not relate to coding.
App.js: The programme’s root component, App.js, is the application’s entry point.
Index.js: The React application is mounted to the DOM in index.js.
This is one possible React file structure. However, it can be structured in multiple ways based on each project’s unique needs.
There are a few things that you must keep in mind before getting started with React on MacOS. Here are a few tips:
Mac is a great option for web developers to create React-based applications. With our in-depth guide, you’ll be able to install and initiate creating optimised web applications within no time!
