React Reverse Portal

React Reverse Portal is a utility library that enables the reparenting of rendered React elements within the DOM without triggering a re-render. Unlike standard React portals which allow an element rendered in one part of the React tree to be physically moved elsewhere in the DOM, reverse portals facilitate pulling an already rendered element from a source location into a target within the React tree. This mechanism is particularly useful for preserving internal React component state and inherent DOM element state (e.g., a playing video) when elements need to be moved, hidden, or reused across different parts of an application. The library is currently at version 2.3.0, actively maintained with a focus on stability and broad React version compatibility (16+). Key differentiators include its small bundle size, zero runtime dependencies, full TypeScript support, and the ability to define props at either the creation or usage location. It's designed for scenarios involving expensive-to-render components that benefit from being instantiated once and then dynamically placed or unplaced.
