react-media-universal v2.0.2

react-media-universal

react-media-universal is a CSS media query component for React, for use with server side rendering.

It is based on react-media and uses the same API, with the addition of a <MediaProvider> component. It solves problems when hydrating a server side rendered app that uses <Media> components for conditional rendering.

Installation

Using npm:

$ npm install --save react-media-universal

Then, use the <MediaProvider> and <Media> component as you would anything else:

// using ES modules
import Media, { MediaProvider } from "react-media-universal";

// using CommonJS modules
var Media = require("react-media-universal");
var MediaProvider = require("react-media-universal").MediaProvider;

The UMD build is also available on unpkg:

<script src="https://unpkg.com/react-media-universal/umd/react-media-universal.min.js"></script>

You can find the library on window.ReactMediaUniversal.

Usage

Make sure to wrap your entire tree in the <MediaProvider> component for the hydration from server side rendering to work properly.

For the API of the <Media> component, see the docs for react-media.

import React from "react";
import Media, { MediaProvider } from "react-media-universal";

class App extends React.Component {
  render() {
    return (
      <MediaProvider>
        <div>
          <Media query="(max-width: 599px)">
            {matches =>
              matches ? (
                <p>The document is less than 600px wide.</p>
              ) : (
                <p>The document is at least 600px wide.</p>
              )
            }
          </Media>
        </div>
      </MediaProvider>
    );
  }
}

If you render a <Media> component on the server, it always matches. To change this behaviour, use the defaultMatches prop:

import React from "react";
import Media, { MediaProvider } from "react-media-universal";

class App extends React.Component {
  render() {
    return (
      <MediaProvider>
        <div>
          <Media
            query="(max-width: 599px)"
            defaultMatches={false}
            render={() => <p>This will not be rendered on the server, nor on the first render pass on client, even if the screen is less than 600px wide.</p>}
          />
        </div>
      </MediaProvider>
    );
  }
}
