React Responsive Components

Creates media queries at provided breakpoints, allowing various components to take different styles at different screen widths, or to be hidden completely.

Why?

When setting up a responsive layout, it would be nice to have a simple way to get each component in the app to know about what the current form factor is, i.e. is the device small like a mobile or wide like a desktop? This library will create the media queries with listeners needed to do this, based on a simple object.

How does it work?

You use two different components, one is the <ResponsiveRoot> and the other is <Responsive>. Wrap something near the Root component of your app with <ResponsiveRoot>. Then wrap your individual components that need to respond to screen size changes with <Responsive>.

The "name" of the currentBreakpoint becomes the responsiveKey prop. <Responsive> will pass this responsiveKey to it's children where the child is a function.

The magic happens by using the same breakpoint objects in <ResponsiveRoot> as in <Responsive>. You can use responsiveHoC to mix your pre-defined breakpoints object into both components. Better yet, you can connect both of these to a redux store, so the <Responsive> wrappers will automatically get notified with the new breakpoint when the form factor has changed.

Example

// RootComponent.jsx
import {
	ResponsiveRoot,
	ResponsiveRootProps,
    Responsive,
    ResponsiveProps,
	responsiveHoC,
	Breakpoint
} from "react-responsive-components"

const breakpoints = [{
    name: "small",
    width: 768
}, {
    name: "medium",
    width: 1024
}, {
    name: "wide",
    width: 1280
}, {
    name: "wider",
    width: 1440
}, {
    name: "widest",
    width: Infinity
}]

interface RootState {
	currentBreakpoint: Breakpoint
}

const ResponsiveRootContainer = responsiveHoC<ResponsiveRootProps>(ResponsiveRoot, breakpoints)
const ResponsiveWrapper = responsiveHoC<ResponsiveProps>(Responsive, breakpoints)

export class RootComponent extends React.Component<void, RootState> {
	constructor() {
		super()
		this.state = {
			currentBreakpoint: breakpoints[0]
		}
		this.currentBreakpointChanged = this.currentBreakpointChanged.bind(this)
	}

	currentBreakpointChanged (currentBreakpoint: Breakpoint) {
		this.setState({ currentBreakpoint })
	}

	render() {
		return (
			<ResponsiveRootContainer currentBreakpointChanged={this.currentBreakpointChanged}>
				<div>
                    <header>
                        <ResponsiveWrapper maxSize="small" currentBreakpoint={this.state.currentBreakpoint}>
                            {(responsiveKey) => (
                                <div className="side-menu-hamburger">
                                    <i name="hamburger" className={`icon-menu-${responsiveKey}`} />
                                </div>
                            )}
                            <ResponsiveWrapper currentBreakpoint={this.state.currentBreakpoint} minSize="medium">
                                <img src="logo.gif" />
                            </ResponsiveWrapper>
                        </ResponsiveWrapper>
                    </header>
					<ResponsiveWrapper currentBreakpoint={this.state.currentBreakpoint} minSize="medium">
						{(responsiveKey: string) => (
						    <Content responsiveKey={responsiveKey} />
						)}
					</ResponsiveWrapper>
				</div>
			</ResponsiveRootContainer>
		)
	}
}
 
// Content.jsx
import { ResponsiveChildProps } from "react-responsive-components"

interface ContentProps extends ResponsiveChildProps {}

export class Content extends React.Component<ContentProps, void> {
	render() {
        return (
            <div className="content">
                <div className={`content-item-${this.props.responsiveKey}`}>
                    <h3 className={`content-item-heading-${this.props.responsiveKey}`}>{props.title}</h3>
                    <div className={`content-item-text-${this.props.responsiveKey}`}>{props.content}</div>
                </div>
            </div>
		)
	}
}
