If you want to use React, use something like Nextjs or Gatsby to compile it into a static HTML website.

Gatsby doesn't compile to a static HTML website. It compiles to a static site. There's a subtle difference. The pages are rendered on the server and served as static assets, but the entire React routing and content loading is still there. When a visitor loads a page it renders and then gets turned from plain HTML back in to a React again. When you navigate from one page to the next all the content for further pages is preloaded. You are not loading a full HTML page for each link you click on (which is exactly what makes it feel so lovely and fast - everything is being preloaded behind the scenes).
