Adds a reusable skill for deploying full-stack apps (React/Vite frontend + Python/FastAPI backend) to Vercel as serverless demos. Covers: - Vercel deploy directory structure - FastAPI serverless function wrapper (api/index.py) - SQLite on /tmp with auto-seeding on cold start - vercel.json rewrite config for SPA + API routing - Gotchas: ephemeral storage, CORS, requirements.txt placement - Vercel CLI quick reference

What
Adds a new skill to the Vellum skills catalog: Deploy Fullstack to Vercel 🚀
A reusable workflow for deploying full-stack apps (React/Vite frontend + Python/FastAPI backend) to Vercel as serverless demos. No auth required — meant for demos, portfolio pieces, and quick showcases.
What the skill covers
api/serverless functions)api/index.py) with propersys.pathsetup/tmpwith auto-seeding on every cold start (the feat: initialize Next.js app in /web directory #1 gotcha)vercel.jsonrewrite config for SPA + API routingWhy
This was battle-tested during a real deployment of a full-stack personal trainer app (FitForge). The biggest lesson learned: Vercel serverless uses ephemeral
/tmpfor SQLite, so ALL required data must be seeded on cold start — not just reference data but also any records the frontend expects to exist (like a default user).How to test
