A React portal component designed for browser extension development

When developing browser extensions with React, you often need to inject React components into host web pages. However, the target mounting points in these pages are frequently dynamic - they may not exist when your extension loads, or they might be created and destroyed as users navigate and interact with the page.

React Magic Portal solves these challenges by automatically detecting when target elements appear or disappear in the DOM, ensuring your React components are always rendered in the right place at the right time.
