Contributing to @swaggerexpert/json-api-merge

As a contributor, here are the guidelines we would like you to follow:

Submission Guidelines

Submitting a Pull Request (PR)

Before you submit your Pull Request (PR) consider the following guidelines:

  • Make your self familiar with git rebase workflow

  • Make your changes in a new git branch:

    git checkout -b my-fix-branch master

  • Create your patch, including appropriate test cases.

  • Follow our Coding Rules.

  • Run the full test suite, as described in the developer documentation, and ensure that all tests pass.

  • Commit your changes using a descriptive commit message that follows our commit message conventions. Adherence to these conventions is necessary because release notes are automatically generated from these messages.

    git commit -a

    Note: the optional commit -a command line option will automatically "add" and "rm" edited files.

  • Push your branch to GitHub:

    git push origin my-fix-branch

  • In GitHub, send a pull request to json-api-merge:master.

  • If we suggest changes then:

    • Make the required updates.

    • Re-run the test suites to ensure tests are still passing.

    • Rebase your branch and force push to your GitHub repository (this will update your Pull Request):

      git rebase master -i
git push -f

That's it!

After your pull request is merged

After your pull request is merged, you can safely delete your branch and pull the changes from the main (upstream) repository:

  • Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:

    git push origin --delete my-fix-branch

  • Check out the master branch:

    git checkout master -f

  • Delete the local branch:

    git branch -D my-fix-branch

  • Update your master with the latest upstream version:

    git pull

Coding Rules

To ensure consistency throughout the source code, keep these rules in mind as you are working:

  • All features or bug fixes must be tested by one or more specs (unit-tests).
  • Every cryptic code block must be documented.
  • We follow Airbnb JavaScript Style Guide, but wrap all code at 120 characters. We use eslint to enforce the codestyle.

Commit Message Guidelines

We have very precise rules over how our git commit messages can be formatted. This leads to more readable messages that are easy to follow when looking through the project history. But also, we use the git commit messages to generate the @swaggerexpert/json-api-merge change log.

Commit Message Format

Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, a scope and a subject:

<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

The header is mandatory and the scope of the header is optional.

Any line of the commit message cannot be longer 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.

Footer should contain a closing reference to an issue if any.

Samples: (even more samples)

docs(changelog): update change log to beta.5

fix(release): need to depend on latest rxjs and zone.js

The version in our package.json gets copied to the one we publish, and users need the latest of these.

refactor(login): make the login form validators more functional

Closes #2

If you want to reference an issue, but the commit doesn't close one use Ref keyword.

style(router): fix linting errors

Ref #3

Revert

If the commit reverts a previous commit, it should begin with revert: , followed by the header of the reverted commit. In the body it should say: This reverts commit <hash>., where the hash is the SHA of the commit being reverted.

Type

Must be one of the following:

  • feat: A new feature
  • fix: A bug fix
  • docs: Documentation only changes
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
  • refactor: A code change that neither fixes a bug nor adds a feature
  • perf: A code change that improves performance
  • test: Adding missing tests or correcting existing tests
  • build: Changes that affect the build system or external dependencies (example scopes: gulp, broccoli, npm)
  • ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
  • chore: Other changes that don't modify src or test files

Scope

The scope could be anything specifying place of the commit change. For example DevicesRoute, logging, etc.

Subject

The subject contains succinct description of the change:

  • use the imperative, present tense: "change" not "changed" nor "changes"
  • don't capitalize first letter
  • no dot (.) at the end

Body

Just as in the subject, use the imperative, present tense: "change" not "changed" nor "changes". The body should include the motivation for the change and contrast this with previous behavior.

Footer

The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.

Breaking Changes should start with the word BREAKING CHANGE: with a space or two newlines. The rest of the commit message is then used for this.

A detailed explanation can be found in this document.
