npm install react-break --save

Compatibility

Compatible with React versions ^15.3.0 and ^16.0.0. For earlier versions of React, use version 1.2.2.

Usage examples

Create components declaratively using layoutGenerator:

import React from 'react';
import { layoutGenerator } from 'react-break';

const layout = layoutGenerator({
  mobile: 0,
  phablet: 550,
  tablet: 768,
  desktop: 992,
});

const OnMobile = layout.is('mobile');
const OnAtLeastTablet = layout.isAtLeast('tablet');
const OnAtMostPhablet = layout.isAtMost('phablet');
const OnDesktop = layout.is('desktop');

const myApp = () => (
  <div>
    <OnMobile>
      Displayed on mobile layout only
    </OnMobile>

    <OnAtLeastTablet>
      Displayed on tablet and desktop layouts
    </OnAtLeastTablet>

    <OnAtMostPhablet>
      Displayed on mobile and phablet layouts
    </OnAtMostPhablet>

    <OnDesktop>
      Displayed on desktop layout only
    </OnDesktop>
  </div>
);

Create layout components manually by using <Break /> component:

import React from 'react';
import Break from 'react-break';

const UIBreakpoints = {
  mobile: 0,
  phablet: 550,
  tablet: 768,
  desktop: 992,
};

const myApp = () => (
  <div>
    <Break
      breakpoints={UIBreakpoints}
      query={{ method: 'is', breakpoint: 'mobile' }}>
      <div>Displayed on mobile layout only</div>
    </Break>

    <Break
      breakpoints={UIBreakpoints}
      query={{ method: 'isAtLeast', breakpoint: 'tablet' }}>
      <div>Displayed on tablet and desktop layouts</div>
    </Break>

    <Break
      breakpoints={UIBreakpoints}
      query={{ method: 'isAtMost', breakpoint: 'phablet' }}>
      <div>Displayed on mobile and phablet layouts</div>
    </Break>
  </div>
);

Props

forceWrap: Set to true if you want the layout components to create a wrapping div also for single child elements. By default the component creates a wrapper only for multiple child elements. Note that setting style or className props has no effects without a wrapping div.

Break component props

Break component takes two props, breakpoints and query. Breakpoints are key-value pairs of arbitrary names and values for layout breakpoints of your choice. Query has two properties: method and breakpoint. The breakpoint-property must be one of the options you defined for the breakpoints attribute. The method-property has three choices: is, isAtLeast and isAtMost, which are described below.

Methods

is matches exactly the given breakpoint, e.g. in the example above is('mobile') matches window sizes from 0px to 549px.

isAtLeast matches the given and any larger breakpoint, e.g. in the example above atLeast('tablet') matches window sizes above 768px.

isAtMost matches the given and any smaller breakpoint, e.g. in the example above atMost('tablet') matches window size below 767px.

layoutGenerator(String [layout method], String [layout name]) -> Component

layoutGenerator is a utility function that allows you to create custom components for breaking the layout, with declarative names.

First you constructing the generator by calling it with the breakpoints object (key-value pairs of breakpoint name and the pixel value). It returns a function that takes two parameters, layout method and a breakpoint name.
