Nuxt 3 is a progressive framework based on Vue.js that enables developers to build server-side rendered applications, static websites, and single-page applications with minimal configuration. It’s an opinionated framework that provides conventions for structuring a Vue.js application, while also allowing flexibility for complex customizations.

This crash course in Nuxt 3 covers its setup process, directory structure, and automatic routing system derived from the file system. It would also dive into its server-side rendering features and the new composition API, which allows developers to write organized and reusable code. The course would likely touch on Nuxt 3’s improved performance, smaller bundle sizes, and better loading times. Additionally, the integration with Vue 3 brings reactivity and composition API improvements to Nuxt, providing more tools and patterns for managing application state and behavior.
