How can I implement server side rendering (ssr) on

Question

I had install my project vuetify with this reference : https://vuetifyjs.com/en/

My project has been 100% complete. Now I want to implement SSR for Search Engine Optimization (SEO)

I search on google and I find there exist 3 option to implement SSR to vuetify project

1. https://ssr.vuejs.org/
2. https://github.com/vuetifyjs/webpack-ssr
3. https://nuxtjs.org/

If I using option 2 or option 3, it seems I must to change my template. Maybe I should rewrite my code on the template. Because my template using vuetify template. I don't know if I choose option 1. Whether it also has to change my template or not. I must to try it first

What I want to ask is if in my position I have completed the 100% vuetify project, which is the best choice I should choose for SSR implementation?

Do I have to rewrite my code or is there another way to implement it?
