React Bounds Element Queries in React

• Like Media Queries - Set min and max values like breakpoints.

• Use the Bounds in JS - Active bounds are passed down as props.

• Use the Bounds in CSS - Use the bound names to style the component with CSS.

Installation & Usage

npm install react-bounds --save

Wrap a Component

Require react-bounds into a component. Wrap the export with bounds.wrap and react-bounds will start tracking the width and height of the component.

var React = require('react');
var bounds = require('react-bounds');

var SomeComponent = React.createClass({
  render(){
    return <div>Some Component</div>
  }
});

module.exports = bounds.wrap(SomeComponent);

Define Bounds

Create a bounds method that returns an object with all of the bound information for that component:

var React = require('react');
var bounds = require('react-bounds');

var SomeComponent = React.createClass({

  bounds() {
    return {
      'bound-name': {
        minWidth: 0,
        maxWidth: 500,
      },
    };
  }

  render(){
    return <div>{ this.props.activeBounds }</div>
  }
});

module.exports = bounds.wrap(SomeComponent);

Use with inline styles via ReactCSS
