react-media-context

React higher-order component (HOC) to provide context for the currently matched media query.

Getting Started

npm i -S react-media-context

Usage

import React from 'react'
import MediaContext from 'react-media-context'

const Title = (props, context) => {
  const { media } = context
  let fontSize = 32
  if (media.indexOf('large') > -1) {
    fontSize = 64
  }

  const style = {
    fontSize
  }

  return (
    <h1 style={style}>
      Responsive Heading
    </h1>
  )
}

Title.contextTypes = {
  media: React.PropTypes.array
}

class App extends React.Component {
  render () {
    <MediaContext>
      <Title />
    </MediaContext>
  }
}

How is this different from x?

Most other responsive React HOCs tend to work on the principle of showing and hiding children based on media queries. With this component, you can alter styling and functionality of components responsively.

This could be handy for:

• Changing font sizes based on the viewport width
• Changing margin or padding
• Grid systems
• Dramatically altering page layout
• Using different routing flows
• Changing image sources based on pixel density (but, srcset is probably a better option)

Props

• queries (Object) - Media queries to match against on window resize

// Default
{
  'xsmall': 'screen and (max-width: 40em)',
  'small': 'screen and (min-width: 40em)',
  'medium': 'screen and (min-width: 52em)',
  'large': 'screen and (min-width: 64em)'
}
