Usage

npm install inline-style-transformer --save

Methods

• toCSS
• toObject
• importantify

toCSS(styles [, options])

Takes a styles object and generates a valid CSS string. Property names get converted to dash-case and plain numbers (if they're not unitless properties) get a configurable unit applied.

import { toCSS } from 'inline-style-transformer'

const styles = {
	fontSize: 15,
	color: 'red',
	transform: 'rotate(30deg)'
}

// basic object to CSS string
const CSS = toCSS(styles)
CSS === 'font-size:15px;color:red;transform:rotate(30deg)'

// custom unit transformation
CSS = toCSS(styles, 'em')
CSS === 'font-size:15em;color:red;transform:rotate(30deg)'

Options

unit

default to px

Add a unit which gets added to plain numbers.

toCSS({width: 30}, {unit: 'em'}) === 'width:30em'

ruleSeparator, selectorSeparator & indent

default to '' (empty string)

Used to format the output rules and classes.

const styles = {
  '.class1': {
    fontSize: 30,
    color: 'red'
  }
}
const options = {
  ruleSeparator: '\n',
  selectorSeparator: '\n',
  indent: '  ' // 2 spaces
}
const CSS = toCSS(styles, options)

Will output a formatted CSS string:

.class1 {
  font-size: 30px;
  color: red
}

toObject(CSS [, options])

Converts a CSS string to a optimized javascript object. Property names get camel-cased and number values get converted to pure numbers if possible.

import { toObject } from 'inline-style-transformer'

const CSS = 'font-size:15px;color:red;transform:rotate(30deg)'

// values with px also get
// converted to pure numbers
const styles = toObject(CSS)
styles === {fontSize: 15, color: 'red', transform: 'rotate(30deg)'}

Advanced

You can also use the new ECMAScript 2015 template strings. This let's you effectively write CSS within javascript.
objectifyCSS will automatically normalize all tabs and line-breaks.

const CSS = `
	font-size: 15px;
	color: red;
	transform: rotate(30deg)
`

const styles = toObject(CSS)
styles === {fontSize: 15, color: 'red', transform: 'rotate(30deg)'}

Options

replacer

Optionally you may pass an object containing replacement rules. Those are used to transform multi-selector CSS into an object.

default is {'.' : ''} which replaces the CSS class prefix . with an empty string.

const CSS = `
  .class1 {
	  font-size: 15px;
	  color: red;
	  transform: rotate(30deg)
  }
  .class2 {
    background-color: blue
  }
`

const styles = toObject(CSS)
// styles === transformed
const transformed = {
  class1: {
    fontSize: 15,
    color: 'red',
    transform: 'rotate(30deg)'
  },
  class2: {
    backgroundColor: 'blue'
  }
}
