js-to-styles-var-loader, which is a more flexible loader, it handles Less, too.This project is not maintained any more. Please try the
- Nodejs >= 4.0
- sass for css pre-processing
- Webpack for module bundle
Setting up Webpack config
Probably you use sass-loader with Webpack. The usage in this case is pretty simple: just put this loader before sass-loader in your webpack config:
rules:test: /\.sass$/use:loader: "style-loader"loader: "css-loader"loader: "sass-loader"loader: "js-to-sass-var-loader"
Let's assume we would like to store some variable data in a module like this:
// colors.jsconst colors ='fancy-white': '#FFFFFE''fancy-black': '#000001';moduleexports = colors;
You can use this module in your favorite templates / frameworks etc., and you don't want to repeat yourself when using these colors in a sass file as variable (e.g.
$fancy-white: #FFFFFE; /*...*/ background-color: $fancy-white). In this situation just require your module in the beginning of your sass module:
;// ...some-classbackground-color: $fancy-white// ...
The form of the required data is important: it must be an object with key/values pair, the key will be the name of the sass variable.
You can use other require form (
You can try the loader via a small fake app in the
cd demonpm inpm run demo
The webpack dev server serves the app on
localhost:8030. In the app we share data between js and sass modules.
Run tests with
npm test or
npm run test:watch.
