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

        <PseudoModal>
          <h2>Pseudo Modal</h2>
          <p>This react component is appended to the document body.</p>
        </PseudoModal>
      </Portal>
    );
  }

}

export class PseudoModal extends React.Component {

  render() {
    return (
      <div>
        {this.props.children}
        <p><button onClick={this.props.closePortal}>Close this</button></p>
      </div>
    );
  }

}

ReactDOM.render(<App />, document.getElementById('react-body'));
