This module is an Aphrodite compatible API on top of JSS. This module is designed to easily switch a large code base from Aphrodite to JSS.
The main difference with aphrodite-jss
is that all of the Aphrodite styles are compatible (ex: css
supports nested arrays, etc).
When using webpack or babel, you can resolve aphrodite
to aphrodite-to-jss
.
$ yarn add aphrodite-to-jss
import React, { Component } from 'react';
import { render } from 'react-dom';
import { StyleSheet, css } from 'aphrodite-to-jss';
const styles = StyleSheet.create({
'@global': {
html: {
textAlign: 'center'
}
},
red: {
backgroundColor: 'red'
},
blue: {
backgroundColor: 'blue'
},
blink: {
animationName: {
from: { opacity: 0 },
to: { opacity: 1 }
},
animationDuration: '3s, 1200ms',
animationIterationCount: 'infinite'
},
hover: {
':hover': {
backgroundColor: 'red'
}
},
small: {
'@media (max-width: 600px)': {
backgroundColor: 'red',
}
}
});
class App extends Component {
render() {
return <div>
<span className={css(styles.red)}>
This is red.
</span>
<span className={css(styles.hover)}>
This turns red on hover.
</span>
<span className={css(styles.small)}>
This turns red when the browser is less than 600px width.
</span>
<span className={css(styles.red, styles.blue)}>
This is blue.
</span>
<span className={css(styles.blue, styles.blink)}>
This is blue and blink
</span>
<span className={css(styles.blue, styles.small)}>
This is blue and turns red when the browser is less than
600px width.
</span>
</div>;
}
}
render(document.body, <App />, () => {
// Difference with aphrodite: need to be called once in the browser
// When not using SSR: it can be called next to StyleSheet.create (before rendering)
StyleSheet.attach();
});
aphrodite-to-jss
takes the best of both worlds:
From Aphrodite:
- ✅ Pseudo-elements:
{ ':hover': { color: 'red' } }
- ✅ Animation keyframes:
{ animation: { from: { opacity: 0 }, to: { opacity: 1} } }
- ✅ SSR autoprefixing: properties are auto-prefixed during server and browser rendering
- ✅ Array fallback:
{ display: ['-webkit-flex', 'flex'] }
- ❌ Font-face: not currently implemented, but could be (PR welcomed !)
From JSS:
- ✅ JSS pseudo-elements:
{ '&:hover': { color: 'red' } }
- ✅ JSS nested:
{ '& .button': { color: 'red' } }
- ✅ JSS global styles:
{ '@global': { html: { color: 'black' } } }
- ✅ Sorted properties:
{ margin: 2, marginRight: 4 }
The API for SSR differs with the one from Aphrodite.
There are 2 functions you need to know - StyleSheet.toCSSString()
and StyleSheet.reset()
. As aphrodite-to-jss
can not know that you are rendering a new response, you need to get the CSS (StyleSheet.toCSSString()
) when you are processing the first request and call StyleSheet.reset()
to clean up the styles your current page has produced.
import { StyleSheet } from 'aphrodite-jss'
function render() {
const app = renderApp()
const css = StyleSheet.toCSSString()
StyleSheet.reset()
return `
<head>
<style>
${css}
</style>
<head>
<body>
${app}
</body>
`
}
Create function doesn't render anything, it just registers your styles.
Returns an object, where key names correspond the original styles object.
This method should be called in the browse, it attach the <style>
element from JSS to the DOM.
When doing SSR, it should be called after the first rendering (after removing the server rendered <style>
element).
When not doing SSR, it can be called when importing aphrodite-to-jss
.
For SSR, it returns the CSS string that have be injected.
Reset the injected styles.
Injects a previously defined rule to the dom. This is done in sync, so the CSS rule is immediately available.
Returns a class name.
