Introduction to Create React App (CRA)

Create React App (CRA) is a toolchain that allows developers to quickly create React applications. It sets up a new project with sensible defaults, including a development server, a build system, and a linter. CRA also provides a number of features that make it easy to develop React applications, such as hot reloading, code splitting, and a built-in development server.

Comparing features of CRA and Next.js - SSR, CSR, maintainability

Next.js is a full-featured framework that provides a number of features out of the box, including server-side rendering (SSR), code splitting, and automatic code optimization. CRA, on the other hand, is a more lightweight toolchain that provides a basic set of features. This makes it a good choice for developers who want more control over their projects or who are already familiar with React.

One of the biggest differences between Next.js and CRA is the way they handle server-side rendering. Next.js uses SSR by default, which means that pages are rendered on the server before being sent to the client. This can improve performance and SEO, but it can also add complexity to the development process. CRA, on the other hand, uses client-side rendering (CSR) by default, which means that pages are rendered on the client side. This can make development easier, but it can also lead to slower performance and worse SEO.

Another key difference between Next.js and CRA is their approach to maintainability. Next.js uses a file-based routing system, which makes it easy to add new pages and components to your project. CRA, on the other hand, uses a component-based routing system, which can be more difficult to understand and use.
