Silence deprecation warnings in Dart Sass

You may see deprecation warnings when compiling your Sass. For example:

DEPRECATION WARNING: Using / for division is deprecated and will be removed in Dart Sass 2.0.0.

You can silence the warnings caused by MOD.UK Frontend and other dependencies.

Make sure you’re using Dart Sass 1.49.10 or higher, and then if you’re:

  • calling the Sass compiler from the command line, pass the --quiet-deps flag
  • using the JavaScript API, include quietDeps: true in the options object

You’ll still see deprecation warnings if you’re using / for division in your own Sass code.
