Ask HN: What are the best ways to build a single-page site?

Depends how complicated it is. If it's a really simple site where you won't be updating the content all too often (or ever), then good old static HTML and CSS should do fine, along with whatever host takes your fancy. Heck, even something like GitHub pages may be a good choice here, since you don't need anything with server side language support for a site this simple.

And if you can avoid bringing in JavaScript frameworks or what not, well all the better there. Making a fast site seems to have become a lost art nowadays, in part due to all the people just bringing in dozens or hundreds of libraries for the simplest possible things.

If you want something more complex? Then look into a framework like React or Vue, or maybe a very basic CMS.

If looking for static site (single page or not), Hugo (https://gohugo.io) + Netlify.com work great!

I was able to easily churn out a single-page "for rent" site using the Hugo Creative theme[0].

I can recommend you https://carrd.co

I love using netlify with a React or Vue app

With or without HTML skills? Im no expert but knocking up a Bootstrap page in notepad++ is easy

I'm using html and surge.sh. It's been great. Deployment is a breeze with their CLI.

Is it static or a web app?

If it doesn't require complicated functionality just use Wix.
