My next.js static blog setup


TL;DR src here https://github.com/cmdcolin/cmdcolin.github.io

Update 2023: converted to app directory mode, see https://cmdcolin.github.io/posts/2023-04-08-nextjs-appdir-blog

My personal homepage originally used statocles, a perl-based static site generator (http://preaction.me/statocles/). I didn't really blog using it, just a homepage for myself plus some links to my tumblr blog. But, if I linked people to the tumblr blog directly, it would give people terrible popup ads and trackers. So, I switched to github pages+next.js this year. I considered a number of alternative static site systems, but next.js seemed to hit some nice goals

Other systems almost worked and were attempted but aborted

#First and second iterations

The first iteration of my next.js blog

The second iteration, I wanted to automatically generate a list of recent blogposts from files on disk

#Stripping off unnecessary stuff from blog-starter-typescript

The blog-starter-typescript template has many tiny components, I removed some of them to make it easier for me to orient myself

#Removing tailwind CSS

The blog-starter-typescript template uses tailwind CSS and uses "modern web design" (aka: gigantic "tiles" instead of links, images that are way too large, etc https://next-blog-starter.vercel.app/)

I started making a more basic design. I tried to roll with the tailwind CSS for a bit, but ended up removing it entirely.

Tailwind CSS is sort of like a CSS-in-JS system, except every CSS attribute is encoded in a CSS classname. For example, here are some tailwind CSS snippets

<div className="container mx-auto px-5"></div>
<footer className="bg-accent-1 border-t border-accent-2"></footer>
<div className="max-w-1xl mx-auto"></div>
<div className="min-h-screen"></div>
<a className="hover:underline"></a>
  className="text-2xl md:text-2xl lg:text-2xl font-bold tracking-tighter leading-tight md:leading-none mb-12 text-center md:text-left"

They claim this is better than using external CSS (see comparison here https://tailwindcss.com/docs/utility-first) but it is yet another language to learn, and kind of tricky.

But, the reason I gave up with tailwind is actually because tailwind CSS resets a lot of HTML styles so things like <h1>, <h2>, <ul>, <li>, <a> have no styling at all. This is done by tailwind preflight https://tailwindcss.com/docs/preflight (which you can disable, but it is enabled by default)

Stackoverflow has some ways to help restore styling and keep preflight, but it still struck me as odd. Examples

To me it was surprising the extend that tailwind goes to unstyle the default browser styles, removing "idiomatic HTML" styles, so I removed tailwind for now. Perhaps I'll return to it another time

#Using MDX for blogposts in next.js

(UPDATE 2022) I no longer use MDX in my blog, my blogposts are all plain markdown and pages tsx, but leave this here for reference

In the template from next.js team, the blog-template-typescript, it uses a fairly simple lib/markdownToHtml.ts function right in the pages/posts/[slug].tsx file (the markdown is statically pre-rendered in the true static blog sense, using the getStaticProps function). This is, unfortunately, over-simplified for the MDX case, because MDX properly needs to hydrate the components using react on the client side also

To fix, the module https://github.com/hashicorp/next-mdx-remote offers a way to load actual MDX files.

#Adding syntax highlighting the next.js code snippets

(UPDATE 2022) I changed to using plain remark with https://github.com/wooorm/starry-night (UPDATE 2022 v2) I changed from starry-night to rehype-highlight. starry-night did not have good typescript/tsx support

There are a couple results from google about how to add syntax highlighting to next.js but I still found it difficult.

My method ended up a bit different where I manually included the prism JS and CSS from a CDN essentially and it worked



Other methods e.g. adding react-prism in next.config.js (like https://github.com/mikeesto/next-mdx-prism-example does) I think clashed with MDXRemote perhaps, or maybe I was tussling with tailwind CSS too much to make a clear thought out of it, but syntax blocks on my blogposts should now be properly highlighted

#RSS feed

I also followed this great guide to add a RSS file for next.js https://ashleemboyer.com/how-i-added-an-rss-feed-to-my-nextjs-site

Link here, for your feed readers https://cmdcolin.github.io/rss.xml

Not many people may use RSS much anymore, but I do use it (via feedly), and I love music blogs that keep posting on blogspot year after year, and the occasional programming post is nice too
