## What it is
Open Web Components (open-wc) is a collection of guides, recommendations, generators, and tools for developing web components in JavaScript. It provides opinionated defaults for scaffolding, linting, testing, building, demoing, and publishing web component projects.

## Use cases
- scaffold a new web component project
- add recommended linting and testing to an existing web components repo
- set up rollup build config for web components
- demo web components with storybook
- learn best practices for developing web components
- publish and automate web component packages

## When to choose
- you are starting or maintaining a standards-based web components project
- you want opinionated, battle-tested defaults for the full web component lifecycle
- you work with lit-element or vanilla web components and want community recommendations

## When to avoid
- you need a full application framework with routing and state management built in
- your project is React/Vue/Angular based and does not use web components
- you want a single small library rather than a suite of tools and generators

## Facets
- artifact type: framework
- maturity: active
- function: developer-tools, build-tool, testing, linter, cli, documentation
- domain: web-development, frontend, developer-tools, tutorials
- platform: browser, cli
- tags: web-components, lit-element, scaffolding, rollup, storybook, opinionated-defaults, monorepo, nodejs, web-server
