This project is no longer being actively maintained. FARFETCH has decided to archive this project, as widely adopted alternatives, like react-responsive, have become available.
We won't be accepting pull requests or responding to issues for this project anymore. Thank you for your understanding.
A package that provides a responsive context to your application, using React Context API.
It has the same API of redux-responsive
and they are easily interchangeable.
$ yarn add @farfetch/react-context-responsive
$ npm i @farfetch/react-context-responsive
...and include it in your project
import { ResponsiveProvider, useResponsive } from '@farfetch/react-context-responsive';
The app, ideally, should have only one <ResponsiveProvider>
, usually at app.js
, wrapping all the components.
You can have as much consumers (useResponsive
, useIsMobile
, Responsive
, withResponsive
and withIsMobile
) as you need. When the Provider value changes, all the consumers will update.
The hooks (useResponsive
and useIsMobile
) are the preferred method of using the context, when possible.
When possible, use the withIsMobile
and useIsMobile
for mobile devices detection. In the future we might use it to automatically splitting of mobile-only code.
Prop | Type | Required | Default | Description |
---|---|---|---|---|
initialMediaType | '_initial' |Â 'xs' |Â 'sm' |Â 'md' |Â 'lg' |Â 'xl' |
no | 'xs' | Initial media type before the calculation of the real measures |
defaultOrientation | 'landscape' |Â 'portrait' |
no | null | Initial orientation before the calculation of the real measures |
children | node | yes | - | React component |
breakpoints | { xs: string, sm: string, md: string, lg: string, xl: string } | no | - | Min breakpoints |
breakpointsMax | { xs: string, sm: string, md: string, lg: string, xl: string } | no | - | Max breakpoints |
mediaQueries | { _initial: string, xs: string, sm: string, md: string, lg: string, xl: string } | no | - | Represents the screen media queries (If this is passed, breakpoints and breakpointsMax props are obsolete) |
mobileBreakpoint | '_initial' |Â 'xs' |Â 'sm' |Â 'md' |Â 'lg' |Â 'xl' |
no | - | It's considered mobile until this breakpoint |
Key | Type | Description |
---|---|---|
mediaType | '_initial' |Â 'xs' |Â 'sm' |Â 'md' |Â 'lg' |Â 'xl' |
Current breakpoint name |
orientation | string | Current browser orientation |
isCalculated | boolean | False on first render. Once true, it means all breakpoints values are based on the window. |
is | { _initial: boolean, xs: boolean, sm: boolean, md: boolean, lg: boolean, xl: boolean } | Object key breakpoint name and value boolean that shows if width is at a certain breakpoint |
lessThan | { _initial: boolean, xs: boolean, sm: boolean, md: boolean, lg: boolean, xl: boolean } | Object key breakpoint name and value boolean that shows if width is less than a certain breakpoint |
greaterThan | { _initial: boolean, xs: boolean, sm: boolean, md: boolean, lg: boolean, xl: boolean } | Object key breakpoint name and value boolean that shows if width is greater than a certain breakpoint |
Key | Type | Description |
---|---|---|
isMobile | boolean | If it's below the mobile breakpoint defined by mobileBreakpoint |
isCalculated | boolean | False on first render. Once true, it means all breakpoints values are based on the window. |
To use the package, you must embrace your code with the ResponsiveProvider
, following the guidelines.
The component has five different exported consumption APIs:
useResponsive
: A hook which returns the responsive objectuseIsMobile
: A hook which returns an object withisMobile
andisCalculated
Responsive
: A render prop componentwithResponsive
: A HoC which passes the responsive data to theresponsive
propwithIsMobile
: A HoC which passesisMobile
andisCalculated
props only
There are two possible options to configure your responsive provider with breakpoints
or with mediaQueries
Using breakpoints
and breakpointsMax
const breakpoints = {
xs: "320px",
sm: "576px",
md: "960px",
lg: "1280px",
xl: "1800px"
};
const breakpointsMax = {
xs: "319px",
sm: "575px",
md: "959px",
lg: "1279px",
xl: "1799px"
};
const App = () => {
return (
<ResponsiveProvider breakpoints={breakpoints} breakpointsMax={breakpointsMax}>
<Content />
</ResponsiveProvider>
);
};
export default App;
Using mediaQueries
const mediaQueries = {
_initial: "(min-width: 0px) and (max-width: 319px)",
xs: "(min-width: 320px) and (max-width: 575px)",
sm: "(min-width: 576px) and (max-width: 959px)",
md: "(min-width: 960px) and (max-width: 1279px)",
lg: "(min-width: 1280px) and (max-width: 1799px)",
xl: "(min-width: 1800px)"
};
const App = () => {
return (
<ResponsiveProvider mediaQueries={mediaQueries}>
<Content />
</ResponsiveProvider>
);
};
export default App;
const Greetings = () => {
const { lessThan } = useResponsive();
if (lessThan.sm) {
return (<p>Hello small screen!</p>);
}
return (<p>Hello medium/big screen!</p>);
};
export default Greetings;
const Greetings = () => {
const { isMobile } = useIsMobile();
if (isMobile) {
return (<p>Hello mobile!</p>);
}
return (<p>Hello desktop!</p>);
};
export default Greetings;
class Greetings extends Component {
render() {
return (
<ResponsiveProvider>
<Content>
<Responsive>
{ (responsive) => ( <Component1 currentBreakpoint={ responsive.mediaType } /> ) }
</Responsive>
<Responsive>
{ (responsive) => ( <Component2 orientation={ responsive.orientation } /> ) }
</Responsive>
</Content>
</ResponsiveProvider>
)
}
}
export default Greetings;
class Greetings extends Component {
render() {
return this.props.responsive.lessThan.sm ? <p>Hello small screen!</p> : <p>Hello big/small screen!</p>
}
}
export default withResponsive(Greetings);
class Greetings extends Component {
render() {
return this.props.isMobile ? <p>Hello mobile!</p> : <p>Hello desktop!</p>
}
}
export default withIsMobile(Greetings);
The gap between window width 0 and the first breakpoint is called _initial
media type.
It fixes a problem at redux-responsive
in the calculation:
If the first breakpoint starts in a number bigger than 0 (let's call it X), it considers that everything between 0 and X as the first breakpoint when it's not true.
For example, our breakpoints start at 320 (XS), redux-responsive
considers 270 as XS, a wrong calculation. We call it _initial
.
React >= 16.8.0
is required to use this package as the ResponsiveProvider
is hook-based.
The non-hook APIs just expose the useResponsive
hook with different APIs, for compatibility with class components.
