title: Can I use Cloud Firestore for E-commerce Website? And how?
body: <p>I have a client asking for an e-commerce website and considering I'm a frontend Vue.js developer and never coded backend ever, I was thinking of using Cloud Firestore for the backend. Can somebody kindly drop down a brief roadmap I will have to follow in order to build an e-commerce site with firestore with user authentication and admin controls?
