BEMNames

A utility for easily creating BEM class names in JS

Installation

npm install @takinabradley/bem-names

Usage:

Create BEM object with BEM.b as desired block name

import createBEM from "@takinabradley/bem-names"

const BEM = createBEM("your-block")
BEM.b // 'your-block'

Get BEM string from element name

BEM.e("your-elem") // 'your-block__your-elem'

Get BEM element with modifier

BEM.e("your-elem", "sharp") //'your-block__your-elem--sharp'

Get BEM block modifier

BEM.e(null, "pointy") //'your-block--pointy'

Better BEM block modifier alternative

BEM.bm("super sucky") // 'your-block--super your-block--sucky'

Better way to add modifiers to elements:

const modifierFunc = BEM.m(<block-or-elem-to-modify>)
modifierFunc('modifier1 modifier2')

Ex:

const modifyNavItem = BEM.m("block-name__nav-item")
//        OR          BEM.m(BEM.e('nav-item'))

modifyNavItem("mod1 mod2")
// 'block-name__nav-item--mod1 block-name__nav-item--mod2'
