Contributing

We are open to, and grateful for, any of your contributions. By contributing to step-flow, you agree to abide by the code of conduct.

Reporting Issues and Asking Questions

Before opening an issue, please search the issue tracker to make sure your issue hasn't already been reported.

New Features

Please open an issue with a proposal for a new feature or refactoring before starting on the work. We don't want you to waste your efforts on a pull request that we won't want to accept.

Code Style

step-flow use semistandard code style. The main rules:

  • semicolons
  • 2 spaces – for indentation
  • Single quotes for strings – except to avoid escaping
  • No unused variables – this one catches tons of bugs!
  • Never start a line with (, [, or `
    • This is the only gotcha with omitting semicolons – automatically checked for you!
    • More details
  • Space after keywords if (condition) { ... }
  • Space after function name function name (arg) { ... }
  • Always use === instead of == – but obj == null is allowed to check null || undefined.
  • Always handle the node.js err function parameter
  • Always prefix browser globals with window – except document and navigator are okay
    • Prevents accidental use of poorly-named browser globals like open, length, event, and name.

Test

Before you submit a pull request. You should pass the auto test case. And if you change some code, you should also add new test case for the changed code or function.

You can use the following command to perform the test:

npm test

Steps for Contributing

  1. Create an issue for the bug you want to fix or the feature that you want to add.
  2. Create your own fork on github, then checkout your fork.
  3. Write your code in your local copy. It's good practice to create a branch based off the master branch for each new issue you work on, although not compulsory.
  4. To run the test suite, first install the dependencies by running npm install, then run npm test.
  5. If the tests pass, you can commit your changes to your fork and then create a pull request from there. Make sure to reference your issue from the pull request comments by including the issue number e.g. #123.

Please try to keep your pull request focused in scope and avoid including unrelated commits.

After you have submitted your pull request, we'll try to get back to you as soon as possible. We may suggest some changes or improvements.

Thank you for contributing!
