classnames-undefined

Wrap the classnames package for better behavior for react16

Install

npm install --save classnames-undefined

or

yarn add classnames-undefined

Usage

Please refer to document of classnames , and we extend it with this behavior: when the return value of classnames is empty string, we turned it into undefined. This can help you to output better HTML when there is no classname for the elements.

const cn = require('classnames')
console.log(cn()) // will output empty string


const cu = require('classnames-undefined')
console.log(cu()) // will output undefined
