Aphrodite-like API on top of JSS.

This project is a merge of good ideas from aphrodite and JSS. It provides an API of aphrodite but fixes lots of limitations and caveats by using JSS as a rendering engine under the hood.

Good parts from aphrodite.

Pretty much like inline styles known from React, except it allows to use the entire CSS.
No CSS is generated until css() function invocation. Only the passed rules are converted to a CSS string and injected.
Theming is possible without any headache or framework integrations.

Benefits compared to aphrodite.

More powerfull rendering abstraction through JSS under the hood. You are using all it's plugins and JSON DSL. To name a few:
- Children, siblings and any other kinds of selectors. (jss-nested)
- Global styles, without auto namespacing (jss-global).
Immediate render upon css() call invocation. It gives you an access to computed styles right after render, no need to use setTimeout(). It also avoids additional recalcs and repaints, which can cause flickers and general performance overhead.
No auto "!important" insertion. You can write a plugin for this though.

Example

import {StyleSheet, css} from 'aphrodite-jss'

const sheet = StyleSheet.create({
  button: {
    border: '1px solid',
    borderRadius: 5,
    fontSize: 'inherit',
    lineHeight: '2.3em',
    padding: '0 1em',
    boxShadow: 'inset 0 1px 0 rgba(255, 255, 255, 0.1)',
    textShadow: '0 -1px 0 rgba(0, 0, 0, 0.25)',
    backgroundRepeat: 'repeat-x',
    color: '#fff',
    fontWeight: 400,
    '& span': {
      marginRight: 5,
      color: '#fff'
    }
  },
  primary: {
    borderColor: '#1177cd #0f6ab6 #0d5c9e',
    backgroundImage: 'linear-gradient(to bottom, #2591ed 0%, #1177cd 100%)',
    backgroundColor: '#1385e5',
    '&:hover': {
      backgroundImage: 'linear-gradient(to bottom, #3c9def 0%, #1385e5 100%)'
    }
  }
})

document.body.innerHTML = `
  <button class="${css(sheet.button, sheet.primary)}">
    <span>&#10004;</span>Primary
  </button>
`

API

Create style sheet.

StyleSheet.create(styles)

Create function doesn't render anything, it just registers your styles.

Returns an object, where key names correspond the original styles obejct.

Inject rules.

css(rule1, [rule2], [rule3], ...)

Injects a previously defined rule to the dom. This is done in sync, so the CSS rule is immediately available.

Returns a class name.

Styles format.

The format for styles is defined in jss. Aprodisiac uses jss-preset-default, so all default presets are already in place.

Customizing JSS.

aphroditeJss(jss, [options])

You can pass your own JSS instance with your custom setup.

Returns aphrodite's interface.

import aphroditeJss from 'aphrodite-jss'
import {create} from 'jss'

const {css, StyleSheet} = aphroditeJss(create())

Serverside Rendering.

There are 2 functions you need to know - toString() and reset(). As aphrodite-jss can not know that you are rendering a new response, you need to get the CSS (toString()) when you are processing the first request and call reset() to clean up the styles your current page has produced.

import {toString, reset} from 'aphrodite-jss'

function render() {
  const app = renderApp()
  const css = toString()
  reset()

  return `
    <head>
      <style>
        ${css}
      </style>
    <head>
    <body>
      ${app}
    </body>
  `
}
