TSX, but not a Virtual DOM

While Knockout-inspired, I do not miss trying to runtime debug change binding issues and want as much "compile-time" type checking as I can get while building a component.

TSX in Typescript is a powerful compile-time type checked template language for HTML and similar trees. With TSX Butterfloat can provide a best-in-class development experience at a fraction of the budget of some other web views.

Butterfloat does not take a "Virtual DOM" approach, but it does try to preserve some "Virtual DOM"-like benefits such as easier component testing with access to DOM-less testing data structures. Instead, Butterfloat takes a "static-by-default" approach to DOM building and only runs its components once (and only once) per component instance.

Butterfloat relies entirely on pure observables to signal changes to be made, and the power of Butterfloat is how it schedules those changes by default for you. It has no Virtual DOM diff/patch routines, it binds changes directly to DOM elements.

The only parts of a Butterfloat component that may change are Observables and Components, everything else is setup once and only once.

I think Butterfloat offers a great type check experience, leveraging a lot of intelligence from intelligent usage of some of Typescript's more advanced features.
