node.js - How to use SASS in Laravel 8?

Question

I want to use SASS in my project in Laravel 8. I have put my scss code under resources/sass/app.scss and added following code to webpack.mix.js:

const mix = require('laravel-mix');

mix.js('resources/js/app.js', 'public/js').sass('resources/sass/app.scss', 'public/css');

However, when I run npm run watch command I get the following error:

> watch
> mix watch

node:internal/crypto/hash:105
    throw new ERR_INVALID_ARG_TYPE(
    ^

TypeError [ERR_INVALID_ARG_TYPE]: The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received undefined

Answer 1

What works for me

mix.js("resources/assets/site/js/app.js", "public/assets/site/js")
    .sass("resources/assets/site/sass/app.scss", "public/assets/site/css").options({
    postCss: [require("autoprefixer"), require("postcss-rtl")], })
