Here are the guidelines we'd like you to follow:
Before you submit your Pull Request (PR) consider the following guidelines:
- Search Github for an open or closed PR that relates to your submission. You don't want to duplicate effort.
- 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.
- Fill out our
Pull Request Template
. Your pull request will not be considered if it is ignored.
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.
The footer should contain a closing reference to an issue if any.
Examples:
docs(readme): update install instructions
fix: refer to the `entrypoint` instead of the first `module`
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.
Must be one of the following:
- build: Changes that affect the build system or external dependencies (example scopes: babel, npm)
- chore: Changes that fall outside of build / docs that do not effect source code (example scopes: package, defaults)
- ci: Changes to our CI configuration files and scripts (example scopes: circleci, travis)
- docs: Documentation only changes (example scopes: readme, changelog)
- feat: A new feature
- fix: A bug fix
- perf: A code change that improves performance
- refactor: A code change that neither fixes a bug nor adds a feature
- revert: Used when reverting a committed change
- style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons)
- test: Addition of or updates to Jest tests
The scope is subjective & depends on the type
see above. A good example would be a change to a particular class / module.
The subject contains a succinct description of the change:
- use the imperative, present tense: "change" not "changed" nor "changes"
- don't capitalize the first letter
- no dot (.) at the end
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.
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.
You may have the need to test your changes in a real-world project or dependent
module. Thankfully, Github provides a means to do this. Add a dependency to the
package.json
for such a project as follows:
{
"dependencies": {
"json-schema-faker-types": "null/json-schema-faker-types#{id}/head"
}
}
Where {id}
is the # ID of your Pull Request.
For your interest, time, understanding, and for following this simple guide.
