@wordpress/viewport Edit

Viewport is a module for responding to changes in the browser viewport size. It registers its own data module, updated in response to browser media queries on a standard set of supported breakpoints. This data and the included higher-order components can be used in your own modules and components to implement viewport-dependent behaviors.

Installation Installation

Install the module

npm install @wordpress/viewport --save

This package assumes that your code will run in an ES2015+ environment. If you’re using an environment that has limited or no support for ES2015+ such as lower versions of IE then using core-js or @babel/polyfill will add support for these methods. Learn more about it in Babel docs.

Breakpoints Breakpoints

The standard set of breakpoint thresholds is as follows:

Name Pixel Width
huge 1440
wide 1280
large 960
medium 782
small 600
mobile 480

Data Module Data Module

The Viewport module registers itself under the core/viewport data namespace.

const isSmall = select( 'core/viewport' ).isViewportMatch( '< medium' );

The isViewportMatch selector accepts a single string argument query. It consists of an optional operator and breakpoint name, separated with a space. The operator can be < or >=, defaulting to >=.

const { isViewportMatch } = select( 'core/viewport' );
const isSmall = isViewportMatch( '< medium' );
const isWideOrHuge = isViewportMatch( '>= wide' );
// Equivalent: 
//  const isWideOrHuge = isViewportMatch( 'wide' );

ifViewportMatches Higher-Order Component ifViewportMatches Higher-Order Component

If you are authoring a component which should only be shown under a specific viewport condition, you can leverage the ifViewportMatches higher-order component to achieve this requirement.

Pass a viewport query to render the component only when the query is matched:

function MyMobileComponent() {
    return <div>I'm only rendered on mobile viewports!</div>;

MyMobileComponent = ifViewportMatches( '< small' )( MyMobileComponent );

withViewportMatch Higher-Order Component withViewportMatch Higher-Order Component

If you are authoring a component which should vary its rendering behavior depending upon the matching viewport, you can leverage the withViewportMatch higher-order component to achieve this requirement.

Pass an object, where each key is a prop name and its value a viewport query. The component will be rendered with your prop(s) assigned with the result(s) of the query match:

function MyComponent( { isMobile } ) {
    return (
        <div>Currently: { isMobile ? 'Mobile' : 'Not Mobile' }</div>

MyComponent = withViewportMatch( { isMobile: '< small' } )( MyComponent );

Code is Poetry.
