classnames-rails

Classnames for Rails - a gem package fork from classnames. A simple javascript utility for conditionally joining classNames together.

Installation

Add this line to your application's Gemfile:

gem 'classnames-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install classnames-rails

Remember!! Add the line below in your application.js

//= require classnames

If you need to use dedupe version(option)

//= require classnames-dedupe

But notice it slow(10x) than original version.

That's it and you can use classNames in Rails now.

Usage

In javascript file you can establish complexity class names together for example:

var navClass = classNames("navbar", "navbar-default");
// "navbar navbar-default"

var navClass = classNames({
  "navbar": true,
  "navbar-default": false
  "hidden": false
});
// "navbar"

// More examples...
classNames('foo', 'bar'); // => 'foo bar'
classNames('foo', { bar: true }); // => 'foo bar'
classNames({ foo: true }, { bar: true }); // => 'foo bar'
classNames({ foo: true, bar: true }); // => 'foo bar'

// lots of arguments of various types
classNames('foo', { bar: true, duck: false }, 'baz', { quux: true }) // => 'foo bar baz quux'

// other falsy values are just ignored
classNames(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'

For more information please reference classNames
