Project “cheat-codes” (clone → run → prod in 5 min)

Each repo is minimal (one feature only) and has a RENDER.md / FLY.md file that shows the exact 3-click deploy.

Feature	Stack	Clone command	Why it’s a cheat-code
Auth	Next.js 14 + NextAuth v5 + Prisma + Postgres	`git clone https://github.com/vercel/nextjs-postgres-auth-starter`	OAuth (Google/GitHub) + JWT cookie + RBAC in 1 file (`middleware.ts`)
Payments	React + Express + Stripe	`git clone --branch one-time-payment https://github.com/stripe-samples/react-elements-card-payment`	Webhook endpoint already written + `.env.example` filled
Real-time	React + Socket.io + Redis adapter	`git clone --branch redis-adapter https://github.com/socketio/chat-example`	1-docker-compose file spins up Redis + Node + React
File uploads	React + NestJS + S3 presigned URL	`git clone https://github.com/asimashfaq/minio-nest-react-upload`	Front-end gets 60-s URL, no backend traffic
CI/CD	GitHub Actions → Fly.io	`git clone https://github.com/superfly/flyctl-actions`	`.github/workflows/fly.yml` – change `app=`name and push
Monorepo	Turborepo + Next (front) + Fastify (api)	`npx create-turbo@latest -e with-docker`	Docker layer caching pre-configured
E2E tests	Playwright + GitHub Actions	`npm create playwright@latest` (choose GitHub Actions)	1 command gives you `tests/` + CI badge

# 1. Clone any repo above
git clone <repo>
cd <repo>

# 2. Lift to prod (example on Fly)
npm install
fly launch --copy-config # answers yes to all
fly deploy

# 3. Seed DB (if Prisma)
npx prisma migrate deploy
npx prisma db seed
