PatternFly Elements

PatternFly Elements is a work-in-progress collection of flexible and lightweight Web Components based on the Unified Design Kit. The repo also includes a generator to build new components. PatternFly Elements are:

Lightweight: small file size, minimal boilerplate, no "framework-like" features.
Universal: write once, use everywhere. PatternFly Elements work in React, Vue, Angular, vanilla JS, anywhere HTML elements are used.
Themable: Make overrides as needed via attributes or CSS variables

The result of these principles is that you can plug one set of components into a wide variety of applications; bringing UX consistency and developer familiarity to any web project.

A Yeoman generator is included for creating web components that meet these goals.

Quick start

git clone git@github.com:patternfly/patternfly-elements.git
cd patternfly-elements
npm install # this will take a while due to lerna bootstrap
npm run dev -- --storybook --docs # This will build and spin up a local server with storybook preview and documentation

Additional dependencies
