This is a continuation to How to Make Your Open Source Project Really Awesome.
In addition to the things recommended in the first part, do the following:
- Talk to your biggest users
- Make it easy to contribute
- Publish releases often
How To Make Your Open Source Project Really Awesome, Part 2
As ClojureWerkz approaches its 3rd birthday, it’s time to expand our (relatively) popular blog post from early 2013, How to Make Your Open Source Project Really Awesome.
The focus of this part is on how to help your users help you, the maintainer. Very few successful open source projects are one man shows. The more people contribute, the better the project can get and less time it will take on your end to maintain it well.
Talk to Your Biggest Users
If your project is reasonably licensed and you maintain it well, eventually there will be people using it in commercial software. Some of them will be one man shops, others are giant public corporations. Most will lie in-between. It’s still possible to identify some key users: those that really push your project to the limits. Their engineers will be filing the most issues, will turn up on your mailing list more often than others, etc.
You need to identify those users and talk to them. Ask them what they do and don’t like, what they find missing, why they decided to use your project over an alternative.
Not only this kind of feedback is the best roadmap for your project, you will build some connections along the way. With ClojureWerkz, we are very fortunate to have commercial users among the companies we admire. Not only that, we now know some of their engineering team members. It’s never a bad position to be in.
Make It Easy to Contribute
We’ve touched on this in the first part. Time to expand on this key subject a little bit.
Identify Low Hanging Fruit Issues
Most contributors start with small issues: contribute a documentation fix here, a tiny feature there, a few extra failing test cases for this issue. Few of your users will jump in and contribute a major feature from the get-go. There are fairly objective reasons for this:
- It takes time to get familiar with a codebase
- People are more confident contributing to the projects where they “know” one of the maintainers
- Contributing major features requires having some experience with the project
All of this takes time. Making it painless for your users to become contributors is perhaps the most important thing you can do. Except for the smallest projects, it usually separates the projects that will die from those that will march on even if you, the author, completely lose interest or ability to work on it.
Here’s a trick we’ve been trying with some of our projects (e.g. Elastisch): label
GitHub issues with
low-hanging fruit. When someone asks how she can help you,
point the person to this label. We’ve seen this work very well for possibly the most
widely used Clojure project out there: Leiningen.
At the time of writing, Leiningen has 217 contributors, which is not a small number by any stretch (the most popular ClojureWerkz projects have something between 25 and 40).
Document Development Setup
Many projects have some kind of development setup that needs to be performed before you can work on it. It can be a database of some kind running locally, or an env variable set to a particular value. For example, testing the Elastisch requires setting an env variable that tells the test suite what’s the name of the local ElasticSearch cluster should be.
On top of that, there can be multiple ways to run the tests, multiple test suites, OS-specific hacks necessary, VM/compiler version requirements, etc. Document as much of this process as you can. It should be dead obvious how to set things up for development.
If you have a specific VCS workflow (e.g. development happens on the branch
master is only used for stable releases), document this as well. Add a CONTRIBUTING.md
file to the repo to make this more visible.
Not doing so will result in frustration for potential contributors. Don’t know about you but I’m not very motivated to contribute to a project that makes it frustrating.
Don’t Be an A-hole
This is a subject of a blog post of its own but be a decent person on the Internet (yes, it’s possible!). Be respectful. Point out various issues in contributed pull request in a reasonably polite way.
Nobody ever will contribute to a project maintained by an a-hole.
Publish Releases Often
This applies to both bug fix releases and development milestone versions. For ClojureWerkz projects, we often publish a new bug fix release when only 1 or 2 bugs were fixed. It’s easy for us to do and may save some pointless work for the users affected by the bugs.
With Leiningen, it takes a couple of commits (version changes) and 2 lines in the terminal to push a new release:
With Leiningen 2.4, it can be as easy as a single command,
It is also an important thing to do for development milestones. Added a couple of neat features to your project? Publish a new beta release. There will be users who were dying to get their hands on this feature, so much so that they’re willing to run a beta in production just to not spend days reinventing the wheel.
As always, state release stability clearly in the change log and release notes.
This helps avoid another common mistake (applicable primarily to JVM languages): forcing your users to use snapshot releases. Snapshot releases make repeatable builds pretty much impossible and some tools (e.g. Leiningen) won’t allow non-snapshot releases depend on snapshot ones.
Give Credit Where Due
It’s always a good idea to give your contributors some credit by mentioning them in the change log. Even better, have a “Thank You, Contributors” section in your release announcement. Few things are as motivating as getting recognized for your work.
Just like it is not terribly hard to make your project approachable, it is also not that hard to make it contributor-friendly. Having a healthy number of contributors (even if it’s just 2-4) ensures that the project will live on even if you no longer have the time (or interest) maintain it. For example, I have a project that I haven’t contributed any code to since 2008. It is still being used and improved by other people.
Maybe more importantly, making your project contributor-friendly will introduce you to a lot of people and may open a lot of doors to you in the software industry, at least in engineering.
