 1 | react-media-queryable
 2 | =====================
 3 | 
 4 | Trigger state updates when a media query matches the current state of the browser.
 5 | 
 6 | Background
 7 | ----------
 8 | 
 9 | [Adaptive Design](https://developer.mozilla.org/en-US/Apps/Design/UI_layout_basics/Responsive_design_versus_adaptive_design)
10 | is characterized as rendering only the content that a user's browser is equipped to handle. This is often used in scenarios where you want the markup for a component to differ based on screen size: showing a table of data, for example, on a desktop-class screen while showing the data as a list on a mobile-class screen.
11 | 
12 | Typically, Adaptive Design is a server-side methodology, where the server parses the User Agent string and delivers the best experience based on the data found there. Server-side User Agent sniffing, however, can be complex, hard to maintain, and often wrong. Single page apps written in JavaScript generate the HTML on the client side and can't take advantage of any server-side Adaptive Design implementation.
13 | 
14 | react-media-queryable is a React component that allows child components to know the rendering capabilities of the browser (via [media queries](https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Media_queries)) and decide how to render themselves based on those capabilities.
15 | 
16 | Usage
17 | -----
18 | 
19 | Use it like any other React component, passing it a set of named media queries as `props`:
20 | 
21 | ```js
22 | var MediaQueryable = require('react-media-queryable'); // also available via amd define or window global
23 | var mediaQueries = {
24 |   small: "(max-width: 800px)",
25 |   large: "(min-width: 801px)"
26 | };
27 | 
28 | <MediaQueryable mediaQueries={mediaQueries} defaultMediaQuery="small">
29 |   <MyComponent />
30 | </MediaQueryable>
31 | ```
32 | 
33 | You must also specify a `defaultMediaQuery` prop, which will get used when no
34 | other media queries match. If a browser does not support matchMedia, the
35 | children will will always receive the default. This is also useful if you're
36 | rendering your component server side.
37 | 
38 | `MyComponent` will now get a `mediaQuery` prop that will be set to the currently matched media query name and can render itself using that information:
39 | 
40 | ```js
41 | var MyComponent = React.createClass({
42 |   render: function() {
43 |     if (this.props.mediaQuery === 'large') {
44 |       return <p>Desktop Experience!</p>;
45 |     } else {
46 |       return <p>Mobile Experience!</p>;
47 |     }
48 |   }
49 | });
50 | ```
51 | 
52 | Whenever a new media query is matched (i.e. screen rotation or browser window resize), the `mediaQuery` prop will update, forcing a re-render of the child component. The media query object that you pass into the `MediaQueryable` component can contain any browser-supported media query definitions.
53 | 
54 | Compatibility
55 | -------------
56 | 
57 | This library makes use of the [`window.matchMedia`](https://developer.mozilla.org/en-US/docs/Web/API/Window/matchMedia) API that's available in IE 10+. If you want to use it in older browsers, you can use the [matchMedia polyfill](https://github.com/paulirish/matchMedia.js/).
