Styled-native-breakpoint-for-web NPM

styled-native-breakpoint-for-web

Add breakpoints to your Styled Components to use for the web in your React Native Universal Expo Web project.

Introduction

When creating a Expo universal app using Styled Components you need desktop breakpoints to deliver a good experience for the web. Your mobile layout is just meant for the mobile web, you are missing our old pal the desktop view.

Styled Components media queries are meant to work just for the web so they are of no use when creating styled components that need breakpoints to work with React Native For Web which is what Expo is using to create your web build.

We are also emulating the responsiveness of web media queries behaviour, so if you resize your browser window and you hit a breakpoint, layout will change accordingly.

Installation

npm install -s styled-native-breakpoint-for-web

Usage with `styled`

Add ThemeProvider as a wrapper to App.js. If you are already using the ThemeProvider component provided by styled-components/native replace it with this one.

You can add your theme in the theme prop or don't use it at all if you are not using a theme right now.

Setup without theme:

//App.js
import ThemeProvider from 'styled-native-breakpoint-for-web';

<ThemeProvider>...your App.js content here</ThemeProvider>;

Setup with theme:

//App.js
import ThemeProvider from 'styled-native-breakpoint-for-web';
import myTheme from 'my-theme-path';

<ThemeProvider theme={myTheme}>...your App.js content here</ThemeProvider>;

import styled from 'styled-components/native';

const MyComponent = styled.View`
  flex: 1;
  background: orangered;
  ${({ theme: { bp } }) =>
    bp.desktop(css`
      background: deepskyblue;
    `)}
`;

Usage with `css` prop

import withTheme and css from styled-components/native and export your component using the HOC.

import { withTheme, css } from 'styled-components/native';
//...rest of MyComponent code
export default withTheme(MyComponent);

With this you will have the theme prop available to consume bp later.

Then when using the css prop simply add an interpolation with theme.bp.lgDesktop()

let {theme} = this.props;
...
<View css={css`
  align-self: center;
  ${theme.bp.lgDesktop(css`
    align-self: flex-start;
  `)}
`}
/>
</View>

Custom breakpoints

By default you get to use 3 breakpoints from bp that have the following values.

{
  tablet: 768,
  desktop: 992,
  lgDesktop: 1200
}

To setup new breakpoints pass the breakpoints prop to ThemeProvider with an object with the key as the name of the breakpoint and the value as number representing the minimum width. Take note that previous defaults will be overwritten.

<ThemeProvider
  breakpoints={{
    ipadPro: 1024,
    lgDesktop: 1280,
    xlDesktop: 1336,
  }}>
  // ...your App.js content here
</ThemeProvider>

import styled, { css } from 'styled-components/native';

const MyComponent = styled.View`
  flex: 1;
  background: orangered;
  ${({ theme: { bp } }) =>
    bp.ipadPro(css`
      background: deepskyblue;
    `)}
  ${({ theme: { bp } }) =>
    bp.xlDesktop(css`
      background: lime;
    `)}
`;
