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
