React-Portal-Minimal

Demo

React-Portal-Minimal is a minimalistic version of React-Portal.

Compared to React-Portal, it is less than 1/3 the size, has minimal options, and no state.

It is intended as a building block. It does only three things:

Hoists its contents to a new React subtree.
Optionally sets a className on the subtree root.
Updates that className on the subtree root if it changes.

Features

Transports its child into a new React component and appends it to the document.body (creates a new independent React tree)
Doesn't leave any mess in DOM after unmount.
no dependencies
fully covered by tests

Installation

npm install react react-dom react-portal-minimal --save
