PatternFly\n \n## Contributing\n\nWe welcome contributions to PatternFly! Please read our [Contributing Guide](https://pf-core-staging.patternfly.org/contribution) to learn how to get started, submit issues, and contribute code to the project. \n\n## Install\n\n- This assumes an environment is already set up for npm packages - if not, please use npm init following the steps at [https://docs.npmjs.com/getting-started/using-a-package.json](https://docs.npmjs.com/getting-started/using-a-package.json).\n- run `npm install @patternfly/patternfly --save`\n\nWhen you install PatternFly, the package includes:\n\n- @patternfly/patternfly/patternfly-base.css - base styles. Global styles, reset/normalize styles, global variables. These styles are required for patternfly styles to work properly.\n- @patternfly/patternfly/patternfly.css - this is patternfly-base.css, as well as all component and layout styles. Does not include utility styles.\n- @patternfly/patternfly/patternfly-addons.css - all utility class styles. These do not come with patternfly.css, and must be imported manually.\n- @patternfly/patternfly/utilities/[UtilityName]/[utility-name].css - individual utility class styles if you prefer only use one or two, and don't want to import all of them.\n- @patternfly/patternfly/patternfly-charts.css - required if using dark theme with [PatternFly charts](https://www.patternfly.org/charts/about-charts).\n\nAny of the files above are meant for use in consuming the library. The recommended consumption approach will vary from project to project.\n\n## Development\n\n**PatternFly Development requires Node v20.18.3 or greater**\n\nTo setup the PatternFly development environment:\n\n- clone the project\n- ensure you have Node.js v20.18.3 or greater installed\n- enable corepack: `corepack enable`\n- run `yarn install` from the project root\n- run `yarn start`\n- open your browser to `http://localhost:8001`\n\nAfter working on your contribution, check for [accessibility violations](#testing-for-accessibility).\n\n### Create components, layouts...\n\nTo create source file scaffolding for a new component, layout, utility, or demo, run the NPM script:\n\n`node generate \u003cCamelName\u003e`\n\nBelow are the full options for this script:\n\n```sh\nOptions:\n  -f, --folder \u003cfolder\u003e  Source folder (components, demos, layouts, or utilities) (default: \"components\")\n```\n\n#### Examples\n\nTo create a \"Test component\" component (`.pf-v6-c-test-component`), run:\n\n`node generate TestComponent`\n\nTo create a \"Test layout\" layout (`.pf-l-test-layout`), run:\n\n`node generate TestLayout -f layouts`\n\nTo create 3 new demos named \"Test demo\", \"Test demo 2\", and \"Test demo 3\", run:\n\n`node generate TestDemo TestDemo2 TestDemo3 -f demos`\n\n\n#### Update screenshots\nWhen making visual changes to a full page example, new example preview screenshots must be generated. To update the screenshots:\n\n- open a terminal and run `yarn build \u0026\u0026 yarn serve`\n- in another terminal, run `yarn screenshots`\n\n## Guidelines for CSS development\n\n- For issues created in Core that will affect a component in PF-React, a follow up issue must be created in PF-React once the Pull Request is merged. The issue should include the Core PR #, the Core Release, a link to the component in https://pf-core-staging.patternfly.org, and information detailing the change.\n- If global variables are modified in Core, a React issue should be opened to address this.\n- CSS developers should ensure that animation is well documented and communicated to the respective React developer.\n- Once the component/enhancement is complete it should receive sign off from a visual designer who can then update the master sketch file with any changes.\n\n### Contribution guide \nFor information on how to contribute, refer to our [contribution guide](https://pf-core-staging.patternfly.org/contribution).\n\n### Development guidelines\nFor more information on using CSS, Sass, and handlebars, refer to our [development guidelines](https://pf-core-staging.patternfly.org/guidelines).\n\n### Custom icon guidelines\nFor more information on custom icons, refer to our [custom icon guidelines](https://pf-core-staging.patternfly.org/custom-icons).\n\n## Beta components\n\nWhen creating a brand new component, it should be released as beta in order to get feedback.\n\n## Testing for accessibility\n\nPatternFly uses [aXe: The Accessibility Engine](https://www.deque.com/axe/) to check for accessibility violations. Our goal is to meet WCAG 2.0 AA requirements, as noted in our [Accessibility guide](https://www.patternfly.org/accessibility/patternflys-accessibility).\n\n### How to perform an accessibility audit with aXe\naXe is available as either a browser extension or npm script.\n\nTo run the a11y audit locally:\n\n- install the latest [chromedriver](http://chromedriver.chromium.org/downloads) and ensure its available on your system `$PATH`\n  - macOS users can simply `brew cask install chromedriver`\n- open a terminal and run `yarn build \u0026\u0026 yarn serve`\n- in another terminal, run `yarn a11y`\n\nThe tool is configured to return WCAG 2.0 AA violations for the full page renderings of all components, layouts, utilities, and demos. The tool will provide feedback about what the violation is and a link to documentation about how to address the violation.\n\nThe same tool is also available as a browser extension for [Chrome](https://chrome.google.com/webstore/detail/axe-devtools-web-accessib/lhdoppojpmngadmnindnejefpokejbdd) and [Firefox](https://addons.mozilla.org/en-US/firefox/addon/axe-devtools/).\n\n### Fixing violations\n\nIgnore the violations that aren’t related to your contribution.\n\nFix violations related to your contribution.\n\nIf there are violations that are not obvious how to fix, then [create an issue](https://github.com/patternfly/patternfly/issues/new) with information about the violation that was found. For example, some violations might require further discussion before they can be addressed. And some violations may not be valid and require changes to the workspace or tooling to stop flagging the violation.\n\nIf you have any suggestions about ways that we can improve how we use this tool, please let us know by opening an issue.\n\n## FAQ\n\n### CSS Variables\n[How do I use CSS variables to customize the library?](https://pf-core-staging.patternfly.org/guidelines#variables)\n\n### Browser support\nPatternFly is supported on the latest two major versions of the following browsers:\n\n- Chrome\n- Firefox\n- Safari\n- Edge\n\n","funding_links":[],"categories":["SCSS","General Purpose","Frameworks / Resources"],"sub_categories":["P"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpatternfly%2Fpatternfly","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpatternfly%2Fpatternfly","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpatternfly%2Fpatternfly/lists"}
