react-with-styles-interface-amp-aphrodite

Interface to use react-with-styles with Aphrodite and Amp.

Import

import ampAphroditeInterface from 'react-with-styles-interface-amp-aphrodite';

or when you need to disable !important:

import ampAphroditeInterface from 'react-with-styles-interface-amp-aphrodite/no-important';

Amp Support

If your app is being rendered with Amp, react-with-styles-interface-amp-aphrodite expects you to set process.env.AMP to 'true' at compile time. This can readily be accomplished by using the following option in your webpack config:

{
  name: 'amp',
  plugins: [
    new webpack.DefinePlugin({
      'process.env.AMP': 'true',
    }),
  ],
}

Built-in RTL support

react-with-styles-interface-amp-aphrodite has built-in LTR/RTL context support. Specifically, it uses rtl-css-js to automatically flip styles (margin, padding, float, textAlign, etc.) that were written for an LTR page when your app is wrapped in react-with-direction's DirectionProvider with direction set to DIRECTIONS.RTL.

It accomplishes this by providing a directional create and resolve method. react-with-styles automatically uses the correct create method based on the direction value set in context and then passes down the appropriate resolve method as a prop named css.

For instance, if you were to write your styles as follows:

import ThemedStyleSheet from 'react-with-styles/lib/ThemedStyleSheet';
import ampAphroditeInterface from 'react-with-styles-interface-amp-aphrodite';
import { withStyles, css } from 'react-with-styles';

ThemedStyleSheet.registerTheme({});
ThemedStyleSheet.registerInterface(ampAphroditeInterface);

function MyComponent({ css }) {
  return <div {...css(styles.container)}>Hello World</div>;
}

export default withStyles(() => ({
  container: {
    background: '#fff',
    float: 'left',
  },
}))(MyComponent);

The generated css for an app where you set <DirectionProvider direction={DIRECTIONS.LTR}> at the top would look like:

.container_r5r4of {
  background: #fff !important;
  float: 'left' !important;
}

whereas if you had set <DirectionProvider direction={DIRECTIONS.RTL}>, the generated css would be:

.container_kui6s4 {
  background: #fff !important;
  float: 'right' !important;
}

If you used an inline style instead:

import { css } from 'react-with-styles';

export default function MyComponent() {
  return <div {...css({ background: '#fff', float: 'left' })}>Hello World</div>;
}

In the case where <DirectionProvider direction={DIRECTIONS.LTR}> is wrapping your component, this would map to a style={{ background: '#fff', float: 'left' }} on the div in question. If <DirectionProvider direction={DIRECTIONS.RTL}> is present instead, this would simply apply style={{ background: '#fff', float: 'right' }} to the div.
