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
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


If you will be doing any release work, it is recommended that you install Hub.

To install on a MacOS: brew install hub.

For other systems, please see documentation: - Hub

Note: You will need to use Node v12 or higher.


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.

Command Line Helper Scripts

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.


# Build all components
npm run build

# Build one or more components
npm run build [component-name(s)]

The build command can accept a few flags; for more details, use npm run build -- --help.


# Runs server process to preview files (does not build)
npm start

# Builds, sets up the watch, and runs server process to preview files
npm run dev [component-name(s)]


New tests (Web Test Runner)

# Run all tests in watch mode.
npm run test:watch

# Run a single test in watch mode.
npm run test:watch --element="pfe-select"
# Or multiple:
npm run test:watch --element="{pfe-select,pfe-card}"

# Run all tests using a React wrapper in watch mode.
npm run test:watch --group="with-react"

# Run all tests using a Vue wrapper in watch mode.
npm run test:watch --group="with-vue"

# Build all elements then run all tests in "watch" mode.
npm run test:build:watch

# Build specific elements then run those tests in "watch" mode.
npm run test:build:watch --element="pfe-select"
# Or multiple:
npm run test:build:watch --element="{pfe-select,pfe-card}"

# Run all tests with and without React and Vue wrappers.
# This is run on pull request within CI.
npm run test:ci

Generate a new test file for an existing element by using:

npm run new:test -- [name-of-element]

# Example:
npm run new:test -- pfe-tabs

🕸 Legacy tests (Web Component Tester)

# Build and run tests on all components
npm run test

# Build and run tests on one component
npm run test [component-name(s)]

# Run tests on one component without rebuilding
npm run test [component-name(s)] -- --nobuild
