Custom Elements Everywhere
summary
Builds a set of vanilla examples called HowTo Components and an automated test site Custom Elements Everywhere to prove interoperability; shows that Shadow DOM is usually required for implementation safety, primitives should reflect attributes↔properties, rich objects must be passed as properties, and events fire only for internal activity. Tests run against popular frameworks: Angular and Vue score 30/30, Preact 24/30, React 16/30. The tools are native custom elements, Shadow DOM, polyfill tests and framework-specific adapters, and the sites work as living diagnostics.
