Sass watch plugin


Hello, I’m looking for a plugin that would replace this :
“watch”: “node-sass css/sass/main.scss css/style.css -w” in package.json
npm run watch

Actually I’ve found plugins that compile a scss file to css, or min.css, but what I’m trying to do is having my main.scss with all the imports, and only compile the main.scss into main.css, leaving all the other scss as imports into the main.
Could anyone please recommend a plugin that does that, and how to configure it ? Thanks
