PatternFly Elements
Table of Contents
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 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 ci # install dependencies.
npm run start
Additional dependencies
nvm
Building PatternFly Elements requires specific versions of Node.js. To automate usage of the correct version, it is recommended that contributors install nvm as well an automatic version switcher like avn or shell-specific nvm integration. With those installed, your terminal will automatically switch to the correct Node.js version when you cd into the PatternFly Elements repository.

Many commands have an optional argument of space-separated component name(s), if left off it will assume it should run on all components. These should run from the project root.
