How to add Compass to the ionic 2 build process? Could you please provide an example?
There already is an answer in the link above, but it is aimed at another mixin (cropper). And is not compass related. I was not able to adapt the solution to compass…
If you’re not totally attached to Compass, I have Bourbon working:
add @import "_bourbon.scss"; to your app.scss
define a custom sass configuration file in package.json using ionic_sass as described here
copy the stock one from node_modules/@ionic/app-scripts/config/sass_config.js and add 'node_modules/bourbon/app/assets/stylesheets' to the includePaths stanza of it
