I don’t mean to shoot down a helpful tutorial, but a solution like this that calls a third-party API to download content for every page view is going to perform badly and possibly crash under heavy load. It’s generally a much better approach these days to use an SSG (Static Site Generator) such as a Jekyll, and you can even use content APIs such as Contentful with an SSG. With the pages being generated once and then propagated through a CDN, you’ll have a blog that can scale from 1 viewer to 1 million viewers without breaking a sweat.
