Nuxt is a framework built on top of Vue that allows us to overcome some of the inherent problems with a single page application (aka SPA).

Why do we need Nuxt?

The primary issue with an SPA with search engine optimization (aka SEO). This is a big topic in itself, but the gist is that it web page contains various pieces of information that can be read by the search engine bots when they index the page. The more information that can be indexed, the higher chance the page has of being found by the search engines.

Nuxt addresses this by either a) generating the content on the server side, and sending fully rendered HTML to the templates, or b) generating static HTML pages, which is far and away the quickest way to provide content to a browser.
