relementjs (Reactive Element)

Isomorphic ui rendering & state management on the browser & server. The smallest reactive UI library on the browser & server. relementjs scales large & small with tree-shakable modules for rendering, reactivity, contexts, & hydration.

relementjs started as a fork from VanJS. The bold use cases have rough equivalence to what VanJS provides. The browser export is smaller than VanJS. The server export is smaller than mini-van-plate/van-plate. relementjs exports rmemo for reactivity & ctx-core/be for contexts.
