How Vercel Serves It

Browser → vercel.app/          → public/index.html  (static)
Browser → vercel.app/api/*     → api/index.js       (serverless Express)

Deploy Steps

Step 1 — Get a free Postgres database

Go to https://neon.tech → New Project → copy the connection string.
It looks like: postgresql://user:pass@ep-xxx.neon.tech/dataproof?sslmode=require

Step 2 — Push to GitHub

git init
git add .
git commit -m "initial commit"
git remote add origin https://github.com/YOUR_USERNAME/dataproof.git
git push -u origin main

Step 3 — Deploy on Vercel

npm install -g vercel
vercel login
vercel
# Answer the prompts:
#   Set up and deploy? Y
#   Which scope? (your account)
#   Link to existing project? N
#   Project name: dataproof
#   Directory: ./
#   Override settings? N

Or connect via the Vercel dashboard: vercel.com/new → Import Git Repository.

Step 4 — Add Environment Variables

In your Vercel dashboard → Project → Settings → Environment Variables, add:

Name	Value
DATABASE_URL	your Neon/Supabase connection string
JWT_SECRET	any random 64-char string
SHELBY_ENDPOINT	https://s3.shelby.xyz
SHELBY_ACCESS_KEY	from Shelby Early Access
SHELBY_SECRET_KEY	from Shelby Early Access
SHELBY_BUCKET	dataproof-datasets
SHELBY_REGION	global
APTOS_NODE_URL	https://api.testnet.aptoslabs.com/v1
APTOS_INDEXER_URL	https://api.testnet.aptoslabs.com/v1/graphql
APTOS_MODULE_ADDRESS	your deployed module address
APTOS_PRIVATE_KEY	your Aptos account private key

Step 5 — Push DB schema

# Set DATABASE_URL locally first (from .env)
cp .env.example .env
# edit .env with your Neon URL
npm run db:push

Step 6 — Redeploy

vercel --prod

Your app is live at https://dataproof.vercel.app (or your custom domain).

Local Dev

npm install
cp .env.example .env   # fill in creds
npm run db:push
vercel dev             # runs both frontend + API locally on port 3000

Notes

• Vercel serverless functions have a 4.5 MB body limit — for large dataset uploads, the UI will need to upload directly to Shelby using a pre-signed URL instead of routing through the API. This is a standard pattern for large file uploads on serverless.
• The frontend has demo data fallback — the UI shows data even if the DB isn't connected yet.
• Free Neon and Supabase both work with Prisma out of the box.
