Hyperapp

Hyperapp is an ultra-lightweight JavaScript framework for building single-page applications, emphasizing minimalism and performance. It integrates state management and a Virtual DOM engine, all within a small footprint (around 1 KB gzipped) and without external dependencies. The current stable version is 2.0.22, with major versions introducing significant feature enhancements and API refinements, though a strict release cadence isn't explicitly stated beyond regular updates. Its key differentiators include its small bundle size, a declarative and purely functional API, and a focus on minimizing the concepts developers need to learn, encompassing views, actions, effects, and subscriptions. It offers a streamlined approach to building performant web applications with an optimized diffing algorithm for efficient DOM updates.
