Scaffold generators

These generators help you kickstart a new app or web component. They will create a new folder and set up everything you need to get started immediately.

Example usage:

npm init @open-wc
# Select "Scaffold a new project"

Available scaffold generators:

• Web Component This generator scaffolds a starting point for a web component. We recommend using this generator when you want to develop and publish a single web component.

• Application This generator scaffolds a new starter application. We recommend using this generator at the start of your web component project.

Features

The above generators are the perfect playgrounds to prototype. Add linting, testing, demoing and building whenever the need arises.

Example usage:

cd existing-web-component
npm init @open-wc
# select "Upgrade an existing project" or add features while scaffolding

Available Upgrade features

• Linting This generator adds a complete linting setup with ESLint, Prettier, Husky and commitlint.

• Testing This generator adds a complete testing setup with Web Test Runner.

• Demoing This generator adds a complete demoing setup with Storybook.

• Building This generator adds a complete building setup with Rollup.
