We love your input! We want to make contributing to this project as easy and transparent as possible, whether it's:
- Reporting a bug
- Discussing the current state of the code
- Submitting a fix
- Proposing new features
- Becoming a maintainer
We use github to host code, to track issues and feature requests, as well as accept pull requests.
We use Github Flow, so all code changes happen through Pull Requests
Pull requests are the best way to propose changes to the codebase (we use Github Flow). We actively welcome your pull requests:
- Fork the repo and create your branch from
master
. - If you've added code that should be tested, add tests.
- If you've changed APIs, update the documentation.
- Ensure the test suite passes.
- Make sure your code lints.
- Issue that pull request!
In short, when you submit code changes, your submissions are understood to be under the same MIT License that covers the project. Feel free to contact the maintainers if that's a concern.
Report bugs using Github's Issues
We use GitHub issues to track public bugs. Report a bug by opening a new issue; it's that easy!
This is an example of a bug report written, and it's not a bad model. Here's another example from Craig Hockenberry.
Great Bug Reports tend to have:
- A quick summary and/or background
- Steps to reproduce
- Be specific!
- Give sample code if you can. My stackoverflow question includes sample code that anyone with a base R setup can run to reproduce what I was seeing
- What you expected would happen
- What actually happens
- Notes (possibly including why you think this might be happening, or stuff you tried that didn't work)
People love thorough bug reports. I'm not even kidding.
Loosely borrowing these from Facebook's Guidelines
- Tabs or four spaces for indentation
- You can try running
npm run lint
for style unification - Name your objects explicity, be descriptive
More detail is available on the repo's wiki, House Styles: Git, but in short.
- Principle: Each branch should have a single purpose.
- Frequency: Every time you want to work on part of a project, create a branch for it.
- Naming Convention:
type/name
- this lets branches of the same type be grouped together in VSTS- Choose short and descriptive names
Note this is not an exhaustive list:
feature Additional functionality or features
bugfix Fixing an error
data Updating data or data connections
format Changing the format/layout
Any suggestions, let us know!
- Principle: Include "what the commit does" as well as "why it does it" if the "what the commit does" message is not sufficient. Like Twitter, any commit message cannot be longer than 80 characters.
- Frequency: Commit often and early, to ensure you don't lose any work. Don't worry about your
git log
orgit nl
looking ugly. You can clean this up afterwards. - Naming Convention: Should follow the below form, where <type> and <subject> are mandatory, whilst <body> and `<footer> are optional.
- If <body> and <footer> are present, <BLANK LINE> is mandatory.
<type>: <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>
Most commits will be of the form <type>: <subject>
.
feat A new feature
fix A bug
docs Documentation only changes
style Changes that do not affect the meaning of the code *e.g. white-space, formatting*
refactor A code change that neither fixes a bug or adds a feature
perf A code change that improves performance
test Add missing tests
chore Changes to build process or auxiliary tools and libraries such as documentation generator
