dva: Elm-style React/Redux Framework

Dva is a lightweight, Elm-style front-end framework designed for building single-page applications by integrating React, Redux, React Router, and Redux Saga into a cohesive development experience. It simplifies state management and side effects through a declarative model system and streamlined data flow, aiming to reduce boilerplate typically associated with Redux setups. The package's last stable release, version 2.4.1, dates back to 2018, with subsequent beta versions for 2.6.0 released in late 2019. The project currently exhibits an abandoned release cadence, with no further stable releases or active development beyond 2019. Its key differentiators include an opinionated, "batteries-included" approach that pre-configures major React ecosystem libraries and its model-centric architecture for managing application state and logic.
