bemmit
A small utility for quickly generating BEM-style naming for CSS classes.
Installation
# Install the package
npm install --save bemmit
Usage
var bemmit = require('bemmit');
// Create an instance of bemmit.
var getClass = bemmit('my-block');
// Now you can quickly add BEM-friendly classes to your HTML:
var myMarkup = `
<div class="${getClass()}">
<h1 class="${getClass('header')}">Choose Your Weapon</h1>
<ul class="${getClass('weapon-list')}">
<li class="${getClass('weapon', ['rubber-chicken'])}">
Rubber Chicken
</li>
<li class="${getClass('weapon', ['feather'])}">
Feather
</li>
<li class="${getClass('weapon', ['colorful-language'])}">
Colorful Language
</li>
</ul>
</div>
`;
This generates the following markup:
<div class="my-block">
<h1 class="my-block__header">Choose Your Weapon</h1>
<ul class="my-block__weapon-list">
<li class="my-block__weapon my-block__weapon--rubber-chicken">
Rubber Chicken
</li>
<li class="my-block__weapon my-block__weapon--feather">
Feather
</li>
<li class="my-block__weapon my-block__weapon--colorful-language">
Colorful Language
</li>
</ul>
</div>
