It’s time to clear some of the backlog. I started this post a few months back and it should probably be sent on its way to clear the pile of drafts I haven’t finished yet… 🤔

I have a bit of a passion for open source software. My preferred distribution of Linux has been Ubuntu since 4.10, the Warty Warthog (I was even a minor contributor on a short lived, wildly popular project that aimed at improving the Ubuntu experience early on), I’ve enjoyed most open source projects I’ve run into, and I thoroughly enjoy supporting open source projects. Recently I had an opportunity to learn a little more than I knew prior to, by being nudged to submit a pull request to a project I’m interested in.

The Project

The project is prettier-eslint’s cli tool, to which I added a (simple) logging option --silly-logs. This came about while running a requested test from Mr. Kent C. Dodds, while the project was still in beta (pre-release). Why am I celebrating a CLI flag for a cli tool? I’m not, I’m more geeking out over the tool itself instead of my minor partial involvement. That’s a part of the beauty of open source, anyone can contribute or help, even with something as small as testing out a beta version.


This led to an observation that while I was getting the benefits of prettier, it was inducing a dangling comma, making it fail my eslint configuration (which explicitly disallows them). While I could reconfigure my eslint config to accommodate for and/or use a dangling comma, that sort of defeats the purpose of plugging into an existing eslint config. The whole point of Mr. Dodds’s prettier-eslint and its cli tool, prettier-eslint-cli which I was testing, was to provide a more seamless integration with the two.

prettier working, just not playing great with eslint


What is prettier? It’s a tool for consistently formatting JavaScript, including support for modern syntaxes, in an opinionated fashion. I liken it to how I have My Eclipse and DDE settings, so that my XML attributes get forcibly formatted onto separate lines. In the end, it’s supposed to help make your code more readable and less confusing. 🎉

The Pull Request

Since it was requested, and it was something I thought would help me learn a little and potentially be of interest to others, I followed Kent’s recommendation and submitted a pull request (PR) to add the --sillyLogs option. Did it go perfectly the first time? Not at all! That’s a sure sign in my book that I’m learning; I was mildly out of my comfort zone and trying something new. In fact, since this time frame, I’ve gone on to find a true appreciation for jest over mocha for my Node test runner and framework; it’s incredibly slick and has lots of great benefits, and I found it thanks to this PR and Kent’s use of, and recommendations of, it.

Since this project was a CLI tool consuming a “regular” Node module (API), so the logging option I added was under a dependent repo’s (PR #8 for prettier-eslint).

The Results

This speaks for itself. Once the logging was established, some modifications were made int he -cli project, and now it plays great with my project’s eslint config. That’s a big win, in my opinion. Here it is, doing what it does w/ the same section of my code, acting as I want and cleaning things up for me.

Shout Out

Now that it has hit version 1.0, the cli tool works great! It formats my code using prettier and triggers an eslint --fix, making my eslint config win in the end, with the formatting assist from prettier. It helps make for some good looking code, so you may wish to check it out. There’s also a package for Atom and for VS Code.

Want to Get Involved?

My suggestion, especially if you’re new at it, is to follow a small handful of developers on Twitter or GitHub; preferably ones with interesting projects that sound useful and innovative to you. Watch, read, learn, listen. When there’s an opportunity to help, go for it. My only words of caution, don’t commit to more than you can do and if you need help, ask for it. You’ll <sarcasm> never guess who one of the developers I follow is </sarcasm> 🙄. In fact, one of the reason I follow Kent is that he actively creates, maintains, and contributes to projects that help people contribute more; in my estimation, that’s one hallmark of a truly good person in the open source world. In fact, he’s even got a (free) series on that is helpful for such beginners, for any interested:

Closing Thoughts

This is far from my first open source contribution, and it certainly won’t be my last, but what stood out to me was that I was more assistive in being aware and willing to test something that just hacking away on my own side projects. Don’t get me wrong, those have plenty of usefulness in their own right, but when we interact with others, we learn how they do things, and that can help us change and grow our own habits, processes, and traits.

Until next time, cheers!
