AI-Powered Video Calling App

A production-ready, TypeScript-first Next.js application that enables AI-enhanced video calling and collaboration. Built with modern tooling for realtime media, messaging, server-side orchestration, and a robust API surface intended for enterprise and developer use.

Key Features

• Real-time video calling and group meetings
• Chat and presence integrated with Stream services
• Server-side event orchestration with Inngest
• Type-safe APIs using tRPC and Drizzle (database schema)
• Role-based dashboard, meeting management, and user flows

Tech Stack

• Framework: Next.js (App Router)
• Language: TypeScript
• Realtime / Media: Stream Video & Stream Chat (see src/lib/stream-video.ts)
• API: tRPC (src/trpc) and Inngest (src/inngest)
• DB: Drizzle ORM (drizzle.config.ts, src/db)
• Styling: Tailwind / CSS modules (see src/app/globals.css)

Architecture Overview

The app uses a server-driven approach where Next.js API routes and tRPC resolvers orchestrate authentication, meeting lifecycle, and background workflows. Realtime media (video/chat) is handled by Stream; background jobs and analytics use Inngest for reliable server-side events.

Quickstart — Development

Prerequisites:

• Node.js 18+ and a package manager (npm, pnpm, or yarn)
• Environment variables (see ./env.example or .env.local)

Install dependencies:

npm install
# or
pnpm install
# or
yarn

Run the dev server:

npm run dev
# opens at http://localhost:3000

Key scripts:

• dev — start development server
• build — production build
• start — start production server after build
• lint — run ESLint

Environment Variables

Create a .env.local file with the required keys. Typical variables used by the project include:

• NEXT_PUBLIC_STREAM_KEY, STREAM_SECRET
• DATABASE_URL (for Drizzle)
• INNGEST_API_KEY
• NEXTAUTH_URL and provider secrets (if used)

Check the source for exact variable names under src/lib and src/api.

Testing & Quality

• Linting: npm run lint
• Add unit and integration tests near the modules they cover. CI should run build, lint, and tests on pull requests.

Deployment

This repository is deployable to Vercel, but any Node-friendly platform works. For Vercel:

# Build and preview locally
npm run build
npm run start

Ensure environment variables are copied into the target environment and secrets are stored securely.

Contributing

• Fork the repo and open a pull request with a clear description
• Follow conventional commits for changelogs
• Add tests for new features and update docs when behavior changes

Troubleshooting

• If video or chat fails, confirm Stream keys and network connectivity
• For DB issues, verify DATABASE_URL and run migrations if applicable

Roadmap & Notes

• Add end-to-end tests for meeting flows
• Enhance observability (metrics, tracing)
• Provide deploy recipes for Kubernetes and serverless
