## What it is
A React library for resolving components asynchronously with support for code splitting and advanced server side rendering. It provides a Promise-based API for lazy-loading components with loading and error states, plus client-side state rehydration to avoid checksum errors.

## Use cases
- lazy load react components with a loading spinner
- code split my react app with import()
- server side render react components that load asynchronously
- avoid react checksum errors with async components
- show error component when chunk loading fails
- prevent flash of content for already resolved components

## When to choose
- you need async React components with full SSR support and state rehydration
- you want a bundler-agnostic code splitting API that works with any major splitting mechanism
- you need loading and error component states out of the box

## When to avoid
- you use modern React 18+ where React.lazy and Suspense cover most needs
- you need an actively maintained library with recent updates
- you only do client-side rendering without SSR complexity
