> Due to customer demands, end-user requirements, and device fragmentation, front-end development has genuinely become _that_ demanding. So as a non-specialist in the field, you can't look at relatively specialist tools like Vite and Nuxt and expect to understand them straight away.
Vite is a set of front end tooling - it provides a local dev server, allows you to work with JSX, CSS and TypeScript, as well as lets you build your app, amongst other things. It handles most things that go between editing your source files and having distribution bundles.
Nuxt is a framework for Vue, that attempts to provide a lot of defaults for your Vue apps and also supports server side rendering or static site generation. It has functionality for handling views, routing, state, configuration, as well as middleware, fetching data and validations.
You can probably describe anything in a way that people would get the gist of it straight away. It doesn't have to be all encompassing, it doesn't even have to be 100% correct, just easy to understand, maybe even with a comparison in there (e.g. npm + webpack). Many such descriptions might just fit into a single paragraph of text, or even a tooltip.
