🤔 Expected Behavior

scss is compiled on both ng serve and parcel ./src/index.html

😯 Current Behavior

ng serve creates project with compiled scss. no errors, parcel ./src/index.html ignores scss files entirely and outputs this error :

💁 Possible Solution

path into angular-cli's usage of scss compilation and use it for parcel or make sure parcel continues to use node-sass as it does with React.

@tatsujb Parcel isn't responsible for the Angular CSS support, the plugin is. It works with React projects because they mostly use the standard import/require. I'm closing this as it's a bug of the Angular plugin, please open an issue on the plugin tracker.
