Next.js describes itself as "The React Framework" for a number of different use cases, ranging from static to dynamic websites, small to large companies, and mobile to classic websites. Next.js lives up to its claim, as 36,000 stars on GitHub indicate; it is extremely popular within the community. For many, Next.js is a serious alternative to Create React App. As opposed to CRA, Next.js supports server-side rendering out of the box, which is especially important for developers optimizing for SEO.
