This is a toolkit that we use internally at Half Helix to develop our frontend Shopify themes. It enables us to develop websites the way that we want to, with a focus on modularity. We developed this tool for our own team but hey, we thought that there might be other people out there that could enjoy this so we made it public.
npm i -g @halfhelix/kit
