Verify it in production

Prove it works, in production

Run through this list on the production URL, not on localhost:

• /signup created your account, and a second attempt with another address is refused.
• You can create a trip with a budget.
• You can add an expense in a foreign currency, and the Canadian total is right.
• You can attach a PDF receipt, and download it again from the expense page.
• The dashboard shows the trip under, near or over budget.
• Export → Excel downloads a .xlsx file with your expense in it.
• Settings → Invitations creates a link bound to one address.

The PDF export on Vercel

The PDF report is printed by a headless Chromium through playwright. Vercel functions do not include a Chromium binary, so on a plain deploy this export is expected to fail while everything else works. Test it, and if it fails you have two honest options:

1. Use a serverless Chromium build. Add @sparticuz/chromium and pass its executablePath() to chromium.launch() in lib/report/pdf.ts. Keep playwright for local runs.
2. Host the app in a container. On Railway, Fly.io or your own server, install Chromium in the image with bunx playwright install --with-deps chromium. The code needs no change.

Option 1 keeps you on the free tier. Option 2 costs a few dollars a month and removes the difference between your laptop and production.

Close the bootstrap door for good

It already closed itself when you signed up: the first account claims a one-row latch that is never released, even if every user is deleted. You can still set AUTH_ALLOW_FIRST_USER=false in Vercel and redeploy, so the setting says what the database already enforces.

You are done

You have a deployed Travole with your own database, your own receipt storage, and you as its only admin. From here:

• read lib/auth/policy.ts to see how one function guards every way to create an account;
• read lib/report/shape.ts to see how one data shape feeds three outputs;
• change lib/db/schema.ts, run bun run db:generate, and ship your first migration — migrate first, deploy second.
