# MeetCast
MeetCast is a video meeting application built with Next.js, LiveKit, PostgreSQL, and TypeScript.
You schedule a room, share an invite, and join with camera, mic, screen share, chat, and basic moderation. Plans control participant counts and meeting duration. Private rooms restrict join to allowlisted account emails.
**Stack:** Next.js 16 · React 19 · TypeScript · Tailwind CSS 4 · Drizzle · Neon Postgres · LiveKit · Vitest · pnpm 12
In-app docs (after `pnpm dev`): open `/docs` on your local app.

## Features
### Meetings
- Create / edit rooms with a start and end time
- Public or private visibility
- Invite links (`inviteCode`)
- Allowed-email list for private rooms (no invite emails — share the link yourself)
- Participant capacity (plan-driven; SFU hard cap 50)
- Status: waiting / active / ended
- Host can end a meeting from the dashboard
### Realtime
- Camera, microphone, screen share
- Participant grid and speaking state
- Chat, raise hand, reactions (LiveKit data channel)
- Soft LiveKit token refresh before JWT expiry
- Reconnect / disconnect banner
### Roles & moderation
- Host, moderator, participant, guest (guests only on public rooms)
- Mute, disable camera, remove participant
- Moderator promote/demote
### Account
- Register / login / logout
- Database sessions (httpOnly cookie)
- Password change, session revoke, account delete
- Soft email verification (login works without verifying)
- Forgot / reset password (Resend optional)
### Plans & billing
- Free / Starter / Pro / Business (seeded in migrations; admins can edit)
- Limits: max concurrent participants, max room duration
- Checkout → order → payment → idempotent fulfill
- ZarinPal when configured; in-app mock gateway in non-production without a merchant
- Current migration sets plan prices to **0** IRR so checkout still runs without a gateway
### Admin
- Users, rooms, plans, orders, audit logs
- Bootstrap admins via `ADMIN_EMAILS`

## Architecture
 [code] 
**Next.js** owns authentication, room access, plan limits, billing fulfillment, admin actions, and LiveKit token minting.
**PostgreSQL** stores durable application data. LiveKit is not the database.
**LiveKit** carries AV and lightweight collaboration. Secrets (`LIVEKIT_API_SECRET`, `AUTH_SECRET`, `DATABASE_URL`) stay server-side.
There is **no** `middleware.ts`, **
