Booster Payback

Receipt submission app for Booster conferences.

Local development

Prerequisites: Bun, Vercel CLI

First, log in to Vercel and link the project (one-time setup):

vercel login
vercel link

Then install dependencies and start the dev server:

bun install
bun run dev

bun run dev will:

1. Pull environment variables from Vercel into .env.local
2. Build the Vercel Blob client
3. Start the server with hot reload at http://localhost:3000

Local development bypasses Slack login and signs you in automatically as a hardcoded dev user. Slack OAuth doesn't support http on localhost callback URLs, unlike sensible companies.

Environment variables are managed via Vercel. After linking the project (vercel link), bun run dev pulls them automatically.
