wasp-lang/open-saas ? reverse-engineered prompt

Build me a starter template for a new SaaS application. I'm looking for a full-stack project using a modern JavaScript stack, probably with React on the front end and Node.js on the back end. It should have all the essential features out of the box so I can get started quickly.

This needs to include a complete user authentication system that supports email/password sign-ups as well as social logins with Google and GitHub. For monetization, please integrate Stripe so I can manage payments and subscriptions. The app should have a clean, modern design with a pre-built admin dashboard. It also needs core SaaS features like sending transactional emails and handling user file uploads. Finally, I want it to be AI-ready, so please set it up to easily call the OpenAI API. Make the whole project easy to deploy when I'm ready.
