clssx

I just got tired of copying these functions throughout my projects and decided to turn then into a simple library.

Installing from npm

yarn add clssx or npm install clssx

Usage

Import csx or ssx from the library

import { csx, ssx } from 'clssx'

Example using react: https://codesandbox.io/s/vigorous-voice-ef38p

csx

It receives any amount of strings, numbers or conditional objects and returns a single string containing the allowed rulesets.

type csx = (...rulesets: Array<string | number | [key:string]: boolean>) => string

Ex:

csx('') // => ''
csx('flex padding-ns') // => 'flex padding-ns'
csx('flex padding-ns', 't-bold') // => 'flex padding-ns t-bold'
 
csx(0) // => '0'
csx(1, 2, 3) // => '1 2 3'
csx(1, 't-bold') // => '1 t-bold'
 
csx({ 'flex padding-ns': false, grow: true }) // => 'grow'
csx({ 'flex padding-ns': false, grow: false }) // => ''
csx({ 'flex padding-ns': true, grow: true }) // => 'flex padding-ns grow'
 
csx(1, { 'flex padding-ns': true }, { grow: true }, 'margin-xl') // => '1 flex padding-ns grow margin-xl'

ssx

It receives any amount of objects or arrays with lenght 2 and returns a single object containing the allowed rulesets.

type ssx = (...rulesets: Array<Object, boolean>) => Object

Ex:

ssx({}) // => {}
ssx({ padding: 1 }) // => {padding: 1}
ssx({ padding: 1 }, { display: 'flex' }) // => {padding: 1, display='flex'}
ssx({ padding: 1 }, [{ display: 'flex' }: false]) // => {padding: 1}
ssx({ padding: 1 }, [{ display: 'flex' }: false], [{ display: 'inline' }: true]) // => {padding: 1, display: 'inline'}
