How do I use nuxt.js for server-side rendering of existing vue spa projects?

A new project that has just been completed takes into account the problem of seo after it is launched. It uses prerender-spa-plugin to pre-render the page, but the dynamic routing page can not achieve the rendering effect. More often, the meta information is returned from the background and cannot be rendered, and other methods cannot be thought of. So we consider using nuxt to render the project on the server side, but we do not know where to start. Can you guys give me some advice?

NUXT.js official document

read the official documents for yourself! It's very comprehensive.
my own website is written in nuxt.js, or the syntax of VUE. It is convenient to use pm2 to manage processes on the server.
