JSass Vars

JSass Vars allows you to defined your scss or sass varibles as a javascript object created from one or more JavaScript modules. JSass Vars will create a valid sass/scss variables file from the object create by the src modules. It also creates a valid JacaScript module with UMD wrapped which will return an object containing all your variables and values for use in your JS scripts. In the browser with out AMD it will create a single global object containing the varibels.

Functions have a special meaning in jSass. When constructing the js and scss files jSass checks if the value is a function. If the value is a function it is executed and the return value is "de-refrenced". This is used to be able to refrence previously defined variables. jSass expects the return value from functions to be a string in the form of "module.property".

Example:

a.js

module.exports = {
	foo: {
		value: "bar"
	}
};

b.js

module.exports = {
	baz: {
		value: () => "a.foo"
	}
};

output.js

module.exports = {
	a: {
		foo: {
			value: "bar"
		}
	},
	b: {
		baz: {
			value: "bar"
		}
	}
};

output.scss

$foo: bar;
$baz: $foo;

Note

The recomended syntax for basic de-refrencing is to use an ES6 arrow function for easy readability

prop: () => "module.prop"
