💪 Adonis: Aphrodite's lover

Adonis combines the best of Aphrodite and styled-components: Named DOM elements, stylable via object literals with support for inheritance, overriding and theming while staying lightweight (28 KB / 7.6 KB gzipped)

Installation

  npm install --save adonis

API

import React, { Component } from 'react'
import adonis from 'adonis'

class App extends Component {
  render () {
    return (<div>
      <Section red>
        This is red.
      </Section>
      <Section hover>
        This turns red on hover.
      </Section>
      <Section small>
        This turns red when the browser is less than 600px wide.
      </Section>
      <Section blue small>
        This is blue and turns red when the browser is less than 600px wide.
      </Section>
    </div>)
  }
}

const Section = adonis.div({
  width: '500px',
  height: '100px',
  textAlign: 'center',
  marginBottom: '20px'
}, {
  red: {
    backgroundColor: 'red'
  },
  blue: {
    backgroundColor: 'blue'
  },
  hover: {
    ':hover': {
      backgroundColor: 'red'
    }
  },
  small: {
    '@media (max-width: 600px)': {
      backgroundColor: 'red'
    }
  }
})

Creating an Adonis Component

Adonis components can be created from DOM elements, React Components or other Adonis Components:

  // A styled `div` tag:
  const Title = adonis.div({
    fontSize: '24px'
  })

  // Overriding `Title`'s styles
  const SubTitle = adonis(Title)({
    fontSize: '15px',
    fontStyle: 'italic'
  })

  // Overriding styles of a React component
  class Button extends React.Component({
    render () {
      // You need to pass the `styles` prop in order to override this component's styles
      return <ButtonContainer styles={this.props.styles} />
    }
  })

  const ButtonContainer = adonis.div({
    padding: '5px 10px'
  })

  // Primary button will have `padding: 5px 10px` as well as `background: blue`
  const PrimaryButton = adonis(Button)({
    background: 'blue'
  })

Variations and flags

Adonis adds support for element variations that can be toggled using properties passed to the element:

const Button = adonis.div(
  // Base styles
  {
    width: '100px',
    height: '50px',
    background: 'grey'
  },
  // Variation styles
  {
    primary: {
      background: 'blue'
    }
  }
)

<Button /> // This would be styled with `background: grey`
<Button primary /> // This would be styled with `background: blue`

Re-usable base styles

You can specify "base" styles that can be re-used in any other component:

const primaryBackgroundColor = adonis.css({
  backgroundColor: 'blue'
})

const Button = adonis(primaryBackgroundColor).button({
  color: 'white'
})

Theming

Similarly to styled-components, you can wrap your React application in a ThemeProvider and pass a theme object.

import { Component } from 'react'
import adonis, { ThemeProvider } from 'adonis'
import AppComponent from './app-component'

const theme = {
  buttonBackgroundColor: 'grey'
}

ReactDOM.render(<ThemeProvider theme={theme}>
  <AppComponent />
</ThemeProvider>, appContainerElement)

You need to make sure that your topmost component is wrapped in withTheme(), so that all child components are receiving the theme:

import { Component } from 'react'
import adonis, { withTheme } from 'adonis'

class AppComponent extends Component {
  render () {
    return <Button />
  }
}

const Button = adonis.div({
  background: 'grey'
})

export default withTheme(AppComponent)

Instead of specifying values inside your style object literals, you can now also pass functions with a theme argument:

const Button = adonis.div({
  background: theme => theme.buttonBackgroundColor
})

Or, if you're using your theme a lot, you can pass a function returning a whole object:

const Button = adonis.div(theme => {
  return {
    background: theme.buttonBackgroundColor,
    borderWidth: theme.buttonBorderWidth,
    borderRadius: theme.buttonBorderRadius,
    color: theme.textColor,
  }
})
