DIY API Documentation

How difficult can writing my own API doc pages be?

I needed a good documentation solution for NodeMC’s RESTful API. But alas, I could find no solutions that really met my particular need. Most API documentation services I could find were either aimed more towards web APIs, like Facebook’s or the various API’s from Microsoft, very, very slow, or just far too expensive for what I wanted to do (I’m looking at you, So, as I usually do, I decided to tackle this issue myself.

The current docs!

I knew I wanted to use Markdown for writing the docs, so the first step was to find a Markdown-to-HTML converter that I could easily automate for a smoother workflow. After a bit of research, I came along Pandoc, a converter that does pretty much everything I need, including adding in CSS resources to the exported file. Excellent. There is also quite a few integrations for several Markdown (or text) editors, but none for vsCode so I didn’t need to worry about those, choosing instead to use the *nix watch command to run my ‘makefile’ every second to build to HTML.

The next decision I had to make was what to use for CSS. I was very tempted to use Bootstrap, which I have always used for pretty much all of my projects that I needed a grid system for. However, instead, I decided on the much more lightweight Skeleton framework, which does pretty much everything I need to in a much smaller package. Admittedly it’s not as feature-packed as Bootstrap, but it does the job for something that is designed to be mostly text for developers who want to get around quickly. Plus, it’s not too bad looking.

So the final piece of the puzzle was “how can I present the information attractively?”, which took a little bit more time to figure out. I wanted to do something like what most traditional companies will do, with a sidebar table of contents, headers, etc. The easiest way to do this was a bit of custom HTML and a handy bit of Pandoc parameters, and off to the races.

Now at this point you’re probably wondering why I’m not just using Jekyll, and the answer to that is… well, I just didn’t. Honestly I wanted to try to roll my own Jekyll-esque tool, which while slightly less efficient still gets the job done.

So where can you see these docs in action? Well, you can view the finished result over at, and the source code for the docs (where you can make suggestions as pull requests) is available on my GitHub, which I hope can be used by other people to build their own cool docs.
