purescript-purview

Uses incremental lambda calculus to propagate model changes directly to the DOM, avoiding virtual DOM diff algorithms, as motivated by the author's claim that 'you might not need the virtual DOM.'

Employs PureScript's type system to enforce constraints on rendering functions, enabling static DOM optimizations for efficient updates, as described in the approach to restrict functions to incrementalizable ones.

Provides an unopinionated toolkit that allows for defining various UI APIs, with an example implementation included, offering a customizable foundation for different use cases.

Restricts rendering to incrementalizable functions to exploit static DOM structure, leading to performance improvements by computing only changed parts, as outlined in the library's design.
