optimal-select

optimal select

A library which creates efficient and robust CSS selectors for HTML elements.

Features

• support UMD (Browser + Node)
• allow single and multiple element inputs
• configurations for excludes can be defined with filters
• micro library (~ 5kb + no external dependency)
• shortest path and fastest selection in comparison

How To Use

import { select } from 'optimal-select' // global: 'OptimalSelect'

document.addEventListener('click', (e) => {
  var selector = select(e.target)
  console.log(selector)  
})

By default following attributes are excluded for robustness towards changes:

• style (inline styles often used for dynamic visualizations)
• data-reactid (reacts element identifier which depends on the current DOM structure)
• data-react-checksum (react string rendered markup which depends on the current DOM structure)

// pass the attribute as additional parameters (extends defaults)
var selector = select(element, {
  excludes: {
    'href': '.*',
    'class': ['^example']
  }
})

TODO

• extend documentation
• add tests
• check attributes in multi-select
• check attributes for complex classname
