Next.js is a react framework that uses React Library to build static and dynamic production-grade scalable applications. Next.js has many-inbuilt functionality which we can adopt without depending on external libraries like Hot code Reload, File-based Routing, SSR, SSG, Auto Code Splitting, Prefetching, Built-in ts support, etc.
Next.js simplifies react app development with great features, it also allows us to write API routes on the same application, so we don’t require to create API separately. Which makes it perfect for the Node ecosystem also.
