Style

Use the GitHub JavaScript Styleguide for your CoffeeScript. Also, use CoffeeScript for more readable code.

Indentation: two spaces.

Testing

Unit tests. Write them. Make sure your code is covered. Follow TDD. For Javascript/Coffeescript, I like Mocha/Should, but feel free to use something else.

Continuous Integration

All projects should have a Travis CI build set up to run unit tests and linting (if applicable) when a PR is made. If a project is Heroku-based, enable review apps so you will get a copy of the app with your changes linked to automatically on the PR.

Continuous Deployment

All merges on master should be deployed automatically (in the case of static GH pages sites, this will be the gh-pages branch). For Heroku, use the GitHub hooks to accomplish this.
