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
