purescript-halogen

Leverages PureScript's type system to catch UI errors at compile time, reducing runtime bugs and ensuring correctness, as highlighted in its emphasis on type-safe applications.

Uses a PureScript-implemented virtual DOM for performant re-renders based on state changes, with performance claimed comparable to React and Angular.

Supports both Elm-like single components and composable multi-component structures, enabling scalable and maintainable UI development.

Entirely written in PureScript, providing a seamless experience for developers already in that ecosystem without JavaScript interoperability overhead.
