Contributing to @patternfly/react-core

Adding a new component

  1. Check for open issues that are not assigned to anyone, and assign yourself. If you do not see an issue for the component you want to contribute open an issue and assign yourself. Assigning yourself will ensure that others do not begin working on the component you currently have in progress.
  2. Generate the component scaffolding by running yarn generate. This will generate a structure that resembles the followingpackages/react-core/src/[type]/[ComponentName]/ index.js - Barrel File exporting public exports ComponentName.js - Component Implementation ComponentName.test.js - Component Tests - Component Docs examples/ - dir for all examples SimpleComponentName.js - Simple Example
  3. Write the component implementation in [Component].js.
  4. Add jest tests to [Component].test.js. All new components must be tested.
  5. Add any additional public exports to index.js
  6. Update the generated [ComponentName].md. See how to create component docs.
  7. Add integration tests to the demo-app found here

Code contribution guidelines

Adhering to the following process is the best way to get your work included in the project:

  1. Fork the project, clone your fork, and configure the remotes:
# Clone your fork of the repo into the current directory git clone<your-username>/patternfly-react.git # Navigate to the newly cloned directory cd patternfly-react # Assign the original repo to a remote called "upstream" git remote add upstream
  1. Create a branch:
$ git checkout -b my-branch -t upstream/master
  1. Generate your component
# Run the tool to Generate the component scaffolding yarn generate
  • When you select the option to generate a PatternFly 4 component, a structure resembling the following is generatedpackages/patternfly-4/react-core/src/[type]/[ComponentName]/ index.js - Barrel File exporting public exports ComponentName.js - Component Implementation ComponentName.test.js - Component Tests - Component Docs
  1. Develop your component. After development is complete, ensure tests and lint standards pass.
$ yarn test

Ensure no lint errors are introduced in yarn-error.log after running this command.

  1. Add a commit using yarn commit:

This project uses lerna to do automatic releases and generate a changelog based on the commit history. So we follow [a convention][3] for commit messages. Please follow this convention for your commit messages.

You can use commitizen to help you to follow [the convention][3].

Once you are ready to commit the changes, please use the below commands:

$ git add <files to be committed> $ yarn commit

... and follow the instruction of the interactive prompt.

  1. Rebase

Use git rebase (not git merge) to sync your work from time to time. Ensure all commits related to a single issue have been squashed.

$ git fetch upstream $ git rebase upstream/master
  1. Push
$ git push origin my-branch
  1. Create a pull request

    • A link to the PatternFly 4 demo documentation will be automatically generated and posted as a comment after the pull request build is complete.
