== Demo ==
The Autoprefixer turnes out to reduce sourceMap quality.
Steps to reproduce:
- Installation
git clone https://github.com/aslushnikov/autoprefixer-breaks-sourcemap
cd autoprefixer-breaks-sourcemap
npm install .
- Build style.scss with autoprefixer
gulp sass
Notice, how the "red" sass variable is not mapped anywhere.
- Build style.scss without autoprefixer (via commenting out autoprefixer pipe in gulpfile.js)
gulp sass
Notice, how "red" sass variable is now matched to CSS property value.
