Next.js 13.1 includes a number of improvements to the app/ (beta) directory, including better reliability and performance, and a new TypeScript plugin for page and layout configuration options. The app directory now includes 9.3kB less client-side Javascript than the pages directory, making it more efficient. In addition, Next.js now has built-in support for module transpilation, replacing the next-transpile-modules package. These updates make Next.js even more powerful and user-friendly for developers. Update today by running npm i next@latest react@latest react-dom@latest eslint-config-next@latest to take advantage of the new features and improvements.
