5 Useful React Commands

React is a popular frontend library for building user interfaces. If you’re a developer working with React, you’ll likely find these 5 useful commands to be time-saving and helpful in your day-to-day work. Let’s dive in!

#1: npx create-react-app

Creating a new React application can be a tedious process, but with the npx create-react-app command, you can quickly scaffold a new project with all the necessary files and dependencies. Simply run npx create-react-app my-app and you’ll have a new React project up and running in no time.

#2: npm start

Once you’ve created a new React project, the npm start command is your go-to for starting the development server. This command will launch your React application in your browser, allowing you to see your changes in real-time as you develop.

#3: npm run build

When you’re ready to deploy your React application to a production environment, the npm run build command comes in handy. This command will create a production-ready build of your application, optimizing and minifying your code for improved performance.

#4: npm test

Testing is an important part of the development process, and React provides built-in support for writing and running tests. Simply use the npm test command to run your test suite and ensure that your React components and functionality are working as expected.

#5: npm run eject

While React’s default configuration is great for getting started, you may find yourself needing more control over your project’s build configuration. In such cases, the npm run eject command can be used to “eject” from the default configuration and make all build dependencies and scripts available for customization.

These 5 useful React commands can save you time and make your development process more efficient. Whether you’re starting a new project, running tests, or deploying to production, these commands will be valuable tools in your React development toolkit.
