Overview

Atomizer is a tool that helps you create Atomic CSS rules (acss.io).

Atomic CSS is a collection of single purpose styling units for maximum reuse that fits well with components in templated frameworks such as React, Ember or Angular. For more information we recommend that you read "Challenging CSS best practices", watch the Atomic CSS presentation, or check this deck.

Install

npm install atomizer -g

Usage

CLI

Usage: atomizer [options] [path]

  Options:

    -h, --help                          output usage information
    -V, --version                       output the version number
    -R, --recursive                     process all files recursively in the path.
    -c, --config=[file]                 source config file if any.
    -r, --rules=[file]                  custom rules file (argument may be passed multiple times)
    -o, --outfile=[file]                destination config file.
    -n, --namespace=[namespace]         adds the given namespace to all generated Atomic CSS selectors.
    -H, --helpersNamespace=[namespace]  adds the given namespace to all helper selectors.
    -w, --watch=[target]                rebuilds when changes are detected in the file, directory, or glob (argument may be passed multiple times and is parsed for Atomic CSS classes)

    --rtl                               swaps `start` and `end` keyword replacements with `right` and `left`.
    --ie                                adds old IE hacks to the output.
    --exclude=[pattern]                 pattern to exclude file to be scanned
    --bump-mq                           increases specificity of media queries a small amount
    --verbose                           show additional log info (warnings).

Example:

atomizer -o atomic.css ./site/*.html
atomizer -o atomic.css ./site/*.html --exclude=*-0.html
atomizer -c config.js -R ./site/ > atomic.css
atomizer -c config.js -n \#myrootclass > atomic.css

API

var Atomizer = require('atomizer');

var defaultConfig = {
    "breakPoints": {
        'sm': '@media(min-width:750px)',
        'md': '@media(min-width:1000px)',
        'lg': '@media(min-width:1200px)'
    },
    "custom": {
        "1": "1px solid #000",
        "foo": "2px dotted #f00"
    },
    "classNames": [
        'Bd(1)',
        'Bd(foo)',
        'Bd(foo)--sm',
        'Bd(foo)--md',
        'D(n)!'
    ]
};

var atomizer = new Atomizer({verbose: true});

// Parse text to find Atomic CSS classes
var foundClasses = atomizer.findClassNames('<div class="D(n)! P(10px) M(20%) Bd(1) Bd(foo)--sm"></div>');

// Generate Atomizer configuration from an array of Atomic classnames
var finalConfig = atomizer.getConfig(foundClasses, defaultConfig);

// Generate Atomic CSS from configuration
var css = atomizer.getCss(finalConfig);
