## What it is
A tiny React library implementing reverse portals, allowing rendered React elements to be reparented anywhere in the tree without re-rendering. It preserves internal component and DOM state (e.g. a playing video or an initialized editor) while moving elements between locations.

## Use cases
- move a react component elsewhere without losing its state
- reuse an expensive-to-render editor instance in multiple places
- persist a playing video element while relocating it in the dom
- render modals or breadcrumbs declaratively from anywhere in the tree
- pool expensive components and place/unplace them on demand
- detach a react node from the dom and reattach it later without rerendering

## When to choose
- you need to reparent react-rendered DOM nodes while preserving state
- you render costly components once and want to reuse them in different tree locations
- you want a more flexible, declarative alternative to normal portals

## When to avoid
- your components are cheap to render and can simply be re-rendered elsewhere
- you need SSR or non-DOM renderers, which reparenting does not support
- you are not using React

## Facets
- artifact type: library
- maturity: stable
- function: ui-components, state-management
- domain: frontend, web-development
