Well, now Lit 2.0 is here and it is smaller, better and faster.
"Our major goals for Lit 2.0 were to reduce size, add powerful new features, improve performance and make some key changes under the hood to facilitate server-side rendering (SSR)... " - Gray Norton
Unlike most libraries, with a new version Lit actually is smaller, meaning your users get features they deserve faster with reduced download times.
Lit also improved its API so you will find it even easier to write clean and maintainable code. It has ultra fast templating, reactive properties so your components can update in response to changing state, a customisation reactive update lifecycle and very easy to use scoped styles.
Perhaps the biggest change of Lit 2.0 is that it is now much simpler to use Lit for SSR. This enables a full range of integration for SSR including using Next.js and even static site generators or even using apps entirely built with Lit.
Every Lit components is a standard web component. This means you can use it anywhere you can use HTML. Be that another web framework, inside other components and plain html.
Lit then becomes the perfect addition for progressively enhancing basic websites, creating shareable components across frameworks and teams especially in the case of design systems.
