Explain
Nuxt.js allows building scalable Vue applications with automatic routing, SSR, SSG, Edge rendering, and server API integration.
It simplifies Vue development by providing file-based routing, server utilities, and project conventions.
Nuxt supports hybrid rendering, static generation, middleware, and server APIs to power modern full-stack applications.
Core Features
