10. Deployment Mastery

Deployment should not be the part that ruins the demo.

This section is built around practical launch paths for common hackathon stacks.

Deployment workflow

  1. Push the code to GitHub.
  2. Connect the repo to the deployment service.
  3. Set environment variables.
  4. Configure auth callbacks.
  5. Test the core user flow.
  6. Verify a live URL.
  7. Keep a backup deployment if possible.

Deployment checklist

Best rule

Deploy early.
A working live link reduces risk more than almost anything else.

Platform quickstarts (verified Sept 2026)

Official docs change often — start from these canonical doc roots and follow the current “Deploy” / “Getting started” page:

Vercel (Next.js / frontend + serverless routes)

  1. Push to GitHub. npm run build must pass locally first.
  2. Import the repo in Vercel → Framework preset auto-detects Next.js.
  3. Add Environment Variables (all server keys + NEXT_PUBLIC_* client keys).
  4. Set the Production branch (usually main).
  5. Deploy → open the production URL, not just the preview URL.
  6. If you use Supabase/Firebase Auth: add the Vercel URL to allowed redirect URLs / authorized domains.

Common gotcha: forgetting NEXT_PUBLIC_ prefix for browser-exposed vars, or adding keys to Preview but not Production.

Railway / Render (backend API + jobs)

  1. Create a Web Service from the GitHub repo.
  2. Set the start command explicitly (e.g. uvicorn main:app --host 0.0.0.0 --port $PORT for FastAPI, node server.js for Node).
  3. Add env vars in the dashboard — never commit .env.
  4. Attach a managed Postgres/Redis if needed, or point at Supabase/Neon.
  5. Add a health-check route (GET /healthz → {"ok": true}) so the platform can tell a good deploy from a bad one.
  6. Test cold start: free/low tiers sleep. Hit the URL 2–3 min before your demo.

Firebase / Supabase (auth + data fast path)

  1. Create the project, enable the Auth providers you actually demo.
  2. Firebase: add your deploy domain under Authentication → Authorized domains.
  3. Supabase: add the deploy URL under Authentication → URL Configuration (Site URL + Redirect URLs).
  4. Use Row Level Security (Supabase) / Security Rules (Firestore) that are open enough for the demo but not true for everything in a public repo — note the tradeoff in your README.
  5. Test sign-up → login → write → read on the deployed URL, in an incognito window.

Environment variable checklist

Copy this into your deploy dashboard and tick it off:

Secrets rule: if a key can spend money or read all data, it never goes in client-side code, a committed .env, a screenshot, or a slide.

Demo-day backup plan

Judges remember “it worked when I clicked it.” Plan for failure:

  1. Primary live URL — the link you submit.
  2. Backup deploy — same code on a second host (e.g. Vercel + Cloudflare Pages for frontend, or Railway + Render for API). Takes 10 min, saves demos.
  3. Offline recording — 60–90 s screen recording of the golden path, recorded after the final deploy. Keep it under ~25 MB for form uploads.
  4. Screenshots — 3–5 key screens in /assets or in slides.
  5. Seeded demo account — demo@hack.local / demo1234 with realistic data already created; never rely on live sign-up during judging.
  6. Kill-switch — a ?demo=1 query param or “Load sample data” button that bypasses flaky third-party APIs with local fixtures.
