Introduction

codemod-utils doesn't provide a utility package to handle CSS. This is because (1) a few different libraries can be used, each with pros and cons, and (2) most codemods for Ember projects concern updating *.{hbs,js,ts} files (more recently, *.{gjs,gts}).

Nonetheless, you can write a codemod to update *.css files. This tutorial will show how to integrate PostCSS. Our target project is assumed to be an Ember app with CSS modules.
