react-styled-shadow-dom (demo)

React shadow DOM that works well with styled-components.

• Uses react-shadow under the hood
• Makes it really simple to use styled-somponents in shadow DOM
• Useful for testing responsive layouts and ensuring isolation from the parent document

Install

npm install --save react-styled-shadow-dom

Usage

Normally, when you try to use react-shadow, CSS styles from styled-components and theming information won't propagate to the shadow DOM.

The following example shows how easy it is to include styled content inside of shadow DOM using react-styled-shadow-dom.

import React, { Component } from 'react'

import StyledShadow from 'react-styled-shadow-dom'
import styled, { ThemeProvider } from 'styled-components'

const InnerBox = styled.div`
  display: flex;
  flex-direction: column;
  justify-content: center;
  align-items: center;
  width: 100%;
  height: 100%;
  background: red;
`

const Text = styled.h4`
  color: #fff;
`

export default () => (
  <ThemeProvider theme={{ mode: 'dark' }}>
    <StyledShadow
      style={{
        width: 320,
        margin: '0 auto'
      }}
    >
      <InnerBox>
        <Text>Hello iframe!</Text>
      </InnerBox>
    </StyledShadow>
  </ThemeProvider>
)

This seems simple, but it's actually fairly involved. It requires the use of StyleSheetManager in order to properly propagate all styles from styled-components.
