Zenhand

Zenhand parses a shorthand CSS selector like string representing an HTML element, and returns an object describing that element.

Example

var {zenhand} = require('zenhand')
// import {zenhand} from 'zenhand'  // If you're using es modules.
 
var obj = zenhand('div#ex.exmpl.info[style=background:red;color:black][data-name=temp]')
console.log(obj)

output:

{ tag: 'div',
  attrs: 
   { class: [ 'exmpl', 'info' ],
     style: { background: 'red', color: 'black' },
     id: 'ex',
     'data-name': 'temp' } }

Install

npm install --save zenhand

or

yarn add zenhand

API

zenhand(str[, opts])

• str The CSS selector like string to convert into an object representing the HTML element. The str is made up of the following parts:
  • The very first part of the string can be an HTML tag, if left out it defaults to div.
  • # defines an id, should only have one, duplicates will overwrite one another, can be placed anywhere in the string after the tag.
  • . defines a class, multiples allowed, duplicates will be added to the class property, can be placed anywhere in the string after the tag.
  • [attr=val] place an attribute definition inside square brackets, multiples allowed, can be placed anywhere in the string after the tag.
• opts An options object.
  • changeStyleCase If true automatic conversion between camelCase and kebab-case for property names, default is true.
• return An object representing the HTML element.

The module also exports two helper functions; toStyleStr and fromStyleStr.

toStyleStr(obj[, fromCase, toCase])

Convert an object representation of CSS styles into a string, optionally converting property case.

var {toStyleStr, zenhand} = require('zenhand')
// Input.
var obj = {
  position: 'absolute',
  'backgroundColor': '#ff0000',
}
 
console.log(toStyleStr(obj, 'camel', 'kebab'))
 
// Output.
'position:absolute; background-color:#ff0000;'

Supports camel for camelCase, kebab for kebab-case, and snake for snake_case.

fromStyleStr(str[, fromCase, toCase])

Convert a str representation of CSS styles into an object, optionally converting property case.

var {fromStyleStr, zenhand} = require('zenhand')
// Input.
var str = 'position:absolute; background-color:#ff0000;'
 
console.log(fromStyleStr(str, 'kebab', 'camel'))
 
// Output.

  position: 'absolute',
  'backgroundColor': '#ff0000',
}
