FAQs on React JS In Urdu ~ JSX and React CLI (part 9 of 9) Video Lecture - Learn React JS: Fundamentals for Front-End Developers (in Urdu) - Front-End Programming

1. React CLI is an important tool for developing React applications, but what is JSX?
Ans. JSX is a syntax extension for JavaScript that allows us to write HTML-like code in our React components. It is not a requirement for using React, but it is commonly used as it provides a more concise and familiar syntax for building user interfaces. JSX is transformed into regular JavaScript function calls and objects by tools like Babel before being executed by the browser.
2. How can I install React CLI?
Ans. To install React CLI, you first need to have Node.js installed on your machine. Once you have Node.js, you can open a terminal or command prompt and run the following command: ``` npm install -g create-react-app ``` This will install the React CLI globally on your machine. After the installation is complete, you can use the `create-react-app` command to create new React projects.
3. Can I use React CLI to build a production-ready application?
Ans. Yes, React CLI provides several built-in features and optimizations that make it easy to create production-ready React applications. It sets up a development environment with live reloading and error handling, and also includes a build script that optimizes and bundles your code for production. The resulting build can be deployed to a web server or a hosting service to make your application available to users.
4. Is it possible to customize the configuration of a React CLI project?
Ans. Yes, React CLI allows you to customize the configuration of your project by using a `react-scripts` package. This package provides a set of scripts and configuration files that control the build process and development server. You can eject the project from React CLI using the `npm run eject` command, which will give you full control over the configuration files. However, ejecting is a one-way operation and should be done with caution, as it removes the ability to easily update React CLI and its dependencies.
5. Can I use React CLI to create a project with TypeScript instead of JavaScript?
Ans. Yes, React CLI supports TypeScript out of the box. When creating a new project, you can specify the `--template typescript` flag to generate a project with TypeScript configuration and files. This will set up the necessary dependencies and configuration files for TypeScript development. TypeScript provides static typing and other language features that can improve the development experience and help catch potential errors early on.
