A Linear-style, single-tenant scheduling app — your own self-hosted alternative to Calendly.

Pick from your event types, share a public booking page, and let guests grab a slot. Your Google Calendar is the source of truth for availability and where the booking lands.

• Next.js 16 (App Router, Turbopack)
• TypeScript, Tailwind v4
• NextAuth v5 (credentials, single admin)
• MongoDB (driver, Atlas-friendly)
• Composio for Google Calendar OAuth + busy-time / event creation
• Vitest for unit tests
• shadcn-style UI primitives built on base-ui + Radix popover

• Public booking pages with searchable timezone picker (auto-detects, IANA list)
• Reschedule + cancel via signed magic-link tokens (/b/[token])
• Admin dashboard, event types, availability editor, bookings inbox, settings
• Light / dark / system theme
• Mobile-friendly Linear-style chrome (hairline borders, mono numerals, single accent)
• Loading skeletons on every admin route

git clone https://github.com/albertshiney/kalendly_public.git kalendly
cd kalendly
npm install
cp .env.example .env.local
# fill in the values in .env.local — see below
npm run dev

Open http://localhost:3000 and you'll be redirected to /login. Sign in with the ADMIN_EMAIL / ADMIN_PASSWORD you set, then connect Google Calendar from Settings.

All seven are required (see lib/env.ts):

1. Import the repo on Vercel.
2. Add all seven env vars under Project → Settings → Environment Variables (Production + Preview).
3. Set NEXTAUTH_URL and APP_URL to your final domain (e.g. https://kalendly.example.com).
4. Redeploy.

The build is tolerant when env vars are missing (won't fail the deploy), but the running site will throw on every request until they're set — set them, then redeploy.
