Lit: a library for building fast, lightweight web components

Lit maintainer here. I should be going to bed, but I'll answer any questions if people have any!

Not sure why Lit showed up on the front page tonight :)

Curious which web platform features are missing that are preventing Web components to complete with React(for application development not widgets)?

I think web components already compete extremely well for application development, and you see very complex apps built with Lit out there: Photoshop, Firefox, Chrome OS, Chrome DevTools.

Apps are well served because they have more control about how components are used: they can import the same shared styles into every component, take are to not double-register elements, etc.

But I think there are some important standards still missing that would open things up even more in the design system and standalone components side:

- Scoped custom element registries. This moves away from a single global namespace of tag names. Seems like it's about to ship in Safari. Chrome next.

- Open styleable shadow roots. Would allow page styles to flow into shadow roots. This would make building components for use with existing stylesheets easier.

- CSS Modules. Import CSS into JS. Shipping in Chrome. About to land in Firefox.

- ARIA reference target: make idref-based reference work across shadow roots
