For existing applications, you can manually install the required packages and update your file extensions to .tsx.
Service Workers: Unregistered by Default
The structure of the project created by Create React App remains largely unchanged. However, service workers are now unregistered by default. To learn more about service workers and progressive web apps, check out the official documentation.
Sass, CSS Modules, and PostCSS: Styling Made Easy
Create React App 2 provides more options for styling your application without requiring complex configurations or ejecting the application. You can now use Sass, CSS Modules, and PostCSS to create visually stunning applications.

node-sassand create a Sass file. - For CSS Modules, follow the
[name].module.cssfile naming convention. - PostCSS is included by default, allowing you to use vendor prefixes and polyfill new CSS features.
React Fragments Short Syntax: Simplifying Your Code
React 16.2 introduced support for fragments, which allow you to return multiple children from a component’s render method. Create React App 2 now supports the short syntax for fragments, making your code even more concise.
Babel Macros: Streamlining Your Development Process
Babel macros allow you to use a special type of Babel plugin without any configuration. With Create React App 2, you can now use macros to perform build-time transformations and simplify your development process.
Custom Proxy Implementation: Flexible API Requests
Create React App 2 introduces a custom proxy implementation, allowing you to configure a proxy server for API requests. This feature provides more flexibility and control over your application’s API interactions.
Yarn Plug’n’Play Mode: Faster App Creation
Yarn Plug’n’Play mode allows your application to work without a node_modules directory. This feature enables faster app creation and improved performance.
