## What it is
Dva is a lightweight React and Redux based front-end framework with an Elm-style architecture, built on redux, redux-saga, and react-router. It organizes app logic into models with reducers, effects, and subscriptions, and offers a plugin system and HMR support.

## Use cases
- build a react app with redux without boilerplate
- manage side effects with redux-saga in an elm-style way
- organize reducers, effects, and subscriptions as models
- create an admin dashboard with ant design and dva
- add hot module reloading for models and routes
- extend state handling with a plugin like dva-loading

## When to choose
- you want an elm-style model organization on top of redux and redux-saga
- you are building react or react-native apps with minimal redux boilerplate
- you use umi and want zero-config dva integration

## When to avoid
- you prefer modern react state solutions like zustand or react query
- you want a framework with frequent updates and a large active community
- your project does not use redux patterns

## Facets
- artifact type: framework
- maturity: maintenance
- function: state-management, frontend-framework, middleware
- domain: web-development, frontend
- platform: cross-platform
