Package Exports

find-unused-sass-variables

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (find-unused-sass-variables) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

find-unused-sass-variables

A simple tool to check for unused Sass variables in a directory.

Install

npm install find-unused-sass-variables --save-dev

Usage

find-unused-sass-variables folder [, folder2...] --ignore "$my-var,$my-second-var"
# or
fusv folder [, folder2...]

API

const fusv = require('find-unused-sass-variables')
// 'scss' is a folder
let unused = fusv.find('scss')
// Array of unused variables
console.log(unused.unused);
// ['$foo', '$bar', '$imunused']
console.log(unused.total);
// Total number of variables in the files

// ignoring variables
const ignoredVars = ['$my-var', '$my-second-var']
unused = fusv.find('scss', { ignore: ignoredVars })

find(dir, options)

dir: string
options: optional options Object

Returns an object with unused and total. unused has the array of unused variables and total has the sum of all variables in the files (unused and used ones).

options.ignore

Array of strings of the variables to ignore, e.g. ['$my-var', '$my-second-var']

Disable & enable

Disable or enable fusv with the fusv-disable and fusv-enable comments:

$used-variable-1: #666;

// fusv-disable
$unused-variable: #coffee;
// fusv-enable

$used-variable-2: #ace;

Notes

The tool's logic is pretty "dumb"; if you use the same name for a variable in different files or namespaces, then it won't distinguish between them.
The tool only looks for .scss files currently.
