I have a fully-functional codebase that combines a front-end, an Express API, and Prisma for data access. Everything runs correctly on my machine, but it still lives only in development. I now need it deployed to production using the stack I have already chosen: on Vercel, the Express server on Railway, and an existing Supabase Postgres instance. The database is set up and populated, so there is no migration work required. What I do need is the entire deployment workflow put in place, along with any environment-variable wiring I may have missed. I can provide the actual secrets; I just need clarity on what must be set where so that the front-end talks to the API and the API talks to Supabase through Prisma. Deliverables • Live, publicly accessible site on Vercel • Expres...
