react-with-breakpoints

Build leaner webpages with react-with-breakpoints like Airbnb. 👌

NOTE: If you have [email protected] installed, using react-with-breakpoints v4 is recommended as it's written with React Hooks and Typescript.

🔧 Install

npm install react-with-breakpoints

# or use yarn

yarn add react-with-breakpoints

👈 Usage

// in index.js
import { BreakpointsProvider } from 'react-with-breakpoints';

const myApp = () => (
  <BreakpointsProvider>
    <App />
  </BreakpointsProvider>
);

// in App.js
import { ShowAt, HideAt } from 'react-with-breakpoints';

const App = () => (
  <ShowAt breakpoint="mediumAndBelow">
    <div>Hello World!</div>
  </ShowAt>
  <HideAt breakpoint="mediumAndBelow">
    <div>Hola Mundo!</div>
  </HideAt>
);

⚡️ Component list

• <BreakpointsProvider />
• <HideAt />
• <ShowAt />

<BreakpointsProvider />

BreakpointsProvider is taking advantage of the new React v16.3 Context API. It is a context provider and therefore it needs to be rendered on the top of your component tree. For more information about React v16.3's Context API please visit this link.

See in an example how you can use it:

// in index.js
import { BreakpointsProvider } from 'react-with-breakpoints';

const breakpoints = {
  small: 468,
  medium: 768,
  large: 1024,
  xlarge: Infinity,
}

const myApp = () => (
  <BreakpointsProvider breakpoints={ breakpoints }> // breakpoints prop is optional
    <App />
  </BreakpointsProvider>
);

NOTE: As you can see in the example above, the breakpoints prop has been moved from HideAt and ShowAt to the BreakpointsProvider component. There is a disadvantage and an advantage of this. You can finally modify the breakpoints object at one place in your app, it became centralised. The disadvantage is that now you need to refactor your code if you manually set the breakpoints in your project if you used v2.

| Prop name | Type | Value | Default value | Description | Required | | --------- | ---- | ----- | ------------- | ----------- | -------- | | breakpoints | Object | { small: Number, medium: Number, large: Number, xlarge: Number } | See it at util/airbnbBreakpoints: { small: 744, medium: 1128, large: 1440, xlarge: Infinity } | Here you can override the default Airbnb breakpoints. It needs to be an object with a strict shape, which is shown at the value row. | false | | onBreakpointChange | Function | (breakpoint) => void | - | Callback invoked on breakpoint change. | false |

<HideAt />

HideAt is a stateless function, which helps you make your DOM leaner. It hides its children, when the proper criterias are met.

Let’s see it in action:

import { HideAt } from 'react-with-breakpoints';

const myApp = () => (
  <HideAt breakpoint="small">
    <div>Hello World!</div>
  </HideAt>
);

Here, the div with the ‘Hello World!’ text is going to appear only if you are viewing your website on a medium or larger sized screen. It’ll be hidden and removed from the DOM on small screen width. HideAt gets the current breakpoint (screen width described as a text eg.: small) from BreakpointsProvider.

NOTE: As HideAt and ShowAt function the same way (they do the opposite things of each other), they share the same props and prop-types.

| Prop name | Type | Value | Default value | Description | Required | | --------- | ---- | ----- | ------------- | ----------- | -------- | | breakpoint | String | Either one of these: 'small', 'medium', 'mediumAndBelow', 'mediumAndAbove', 'large', 'xlarge' | - | You can set either one of the values to tell the component where to hide or show its children. | true | | currentBreakpoint | String | Either one of these: 'small', 'medium', 'large', 'xlarge' | - | It's used by withBreakpoints. Whenever there is a change with the breakpoints, the appropriate value will be passed down to HideAt or ShowAt. | false |

<ShowAt />

ShowAt functions the opposite way as HideAt does. It reveals its children when the current breakpoint matches its breakpoint. (eg.: small, smallAndBelow)

As said above, ShowAt and HideAt share the same props and propTypes, so please look at the prop descriptions at HideAt.

import { ShowAt } from 'react-with-breakpoints';

const myApp = () => (
  <ShowAt breakpoint="mediumAndBelow">
    <div>Hello World!</div>
  </ShowAt>
);

👏 Story

I wrote a 4 min long story on Medium about what I learned along the way, when I created the first version of these three modules. It got published in DailyJS. 🤗
