Hey dudes I've been searching for a way to implement a central login system for like 2 or 3 apps we have, and I'm really confused by the number of options available and the limitations we have in our infrastructure! Most of them require docker to install but our server (shared Node.js host) doesn't support it and I'm not experienced enough to use a VPS. So... I decided to use NextAuth for frontend (our apps are written with Next.js) and connect it to a SuperTokens backend. How can I install SuperTokens in a shared node.js host without docker? (How is Docker image different form
npm i supertokens-node
