SCSS Toolkit

A small and configurable SCSS Toolkit to boost your project! 🚀

Installation

Install it with Yarn:

$ yarn add @studiometa/scss-toolkit

Or with NPM:

$ npm install @studiometa/scss-toolkit

Usage

Simple Usage

Import the toolkit in your project to have access to all helpers functions, mixins, variables and classes:

@import '~@studiometa/scss-toolkit';

If your current Sass implementation does not support @imports from Node modules, have a look at the node-sass-magic-importer custom importer.

Advanced usage

If you need to specify a custom configuration — you probably will, the best way to use the micro framework in your application is to create a separate _config.scss file which will override the configurations of the framework.

_config.scss

/*==========================================================================*\
   Global SCSS configuration
\*==========================================================================*/

// Colors definition
$colors: (
  'red': #f00,
  'green': #0f0,
  'blue': #00f,
);

// Import SCSS Toolkit after the configuration overrides
@import '~@studiometa/scss-toolkit';

You can then import your _config.scss file wherever you need to access a function, mixin or variable from the toolkit. You can import both your configuration file and the SCSS Toolkit package in your main SCSS file with a variable $has-classes set to true to import all the class helpers from the toolkit.

app.scss

/*==========================================================================*\
   Main styles
\*==========================================================================*/

// Import dependencies:
// - _config.scss to override the SCSS toolkit's defaults
// - @studiometa/scss-toolkit/components/reset to get some nice defaults
@import './config';
@import '~@studiometa/scss-toolkit/components/reset';

// Import your project files
@import './components/foo';
@import './components/bar';
// ...

// Import the toolkit latst with the `$has-classes` variable set to `true`
// for the functions, mixins and classes helpers. Importing it last will let
// you use the classes without the `--force` modifier to override some
// of your components behaviours.
$has-classes: true;
@import '~@studiometa/scss-toolkit';
$has-classes: false;

⚠️ We reset the $has-classes variable to false right after the toolkit import to make sure future import in any SCSS file will only import the mixins, functions and variables declarations without the class helpers.
