Nuxt is great for single page app development, but it can be a little tricky deploying your site so that it's live on the web.
Here, I'll show you one method for deploying a Nuxt site: Netlify.
Netlify is a cloud hosting and build provider that'll run all the necessary steps to get your site up and running on an actual URL. One of the coolest things about (which I admittedly forgot to mention in the video) is that it has automatic deploys, meaning, whenever you push a change up to your Git repo, Netlify will automatically update your site URL with all of your new code.
You'll need a GitHub and Netlify account in order to complete this tutorial, both which are free:
In the end, you'll have your site up and running on a Netlify generated URL, but you'll have to purchase a domain and continue with Netlify's steps on your own if you'd like to go further.
