How do I use this without a bundler?

[douglas-legulas]

My employer doesn't let me use a bundler such as Webpack for our web apps (browser environment only), so what are my options?

I do use Dart Sass to compile .scss files into .css. The built files are committed to the git repository so they don't need to have Sass installed on the server.

You can use postcss-cli to process .css files
