Notes on Enterprise Video Calling Integration

Introduction

• Integrating video calling into an app can seem complex and time-consuming
• This lecture addresses creating an enterprise-ready video and audio experience in a few hours
• Goals: build a scalable video calling app for millions of users with thousands of participants

Technologies Used

• TypeScript: for type safety and robust code
• Next.js 14: for server-side rendering and optimized performance
• Tailwind CSS: for utility-first styling
• ShadCN UI: for pre-built, customizable components
• Clerk: for user authentication and management
• Stream: for real-time video, audio, and conferencing functionality
• Figma: for design reference and consistency

Project Overview

• Account Creation: User accounts created through Clerk's sign-in component allowing multiple social sign-ins
• Initiating Meetings: Users can initiate new meetings immediately, with options for camera and microphone setup
• **Meeting Features: ** Full control over meeting experiences, including recording, emoji reactions, screen sharing, and more
• Scheduling Meetings: Future meetings can be scheduled, with links ready to share
• Past Meetings: Access to recordings of past meetings
• Personal Room: Each user has their own personal room and unique meeting link
• Joining Meetings: Capability to join meetings via links

Project Development

1. **Setup: **
   • Create a new Next.js project
   • Install necessary dependencies
   • Include Tailwind CSS for styling and ShadCN UI for component library
2. Routing and Layouts:
   • Utilize Next.js file-based routing
   • Organize routes in logical groups (e.g., sign-in, home)
   • Create shared layouts for consistent UI elements like navbars and sidebars
3. Sidebar and Navbar:
   • Implement responsive sidebar and navbar with navigation to various sections
   • Dynamically highlight active routes
4. Authentication with Clerk:
   • Set up Clerk for user authentication
   • Customize sign-in and sign-up pages to match the app's design
   • Ensure private routes using middleware
5. Home Page Design:
   • Create a banner with upcoming meeting details
   • Develop interactive cards for starting, scheduling, viewing, and joining meetings
6. Video Integration with Stream:
   • Set up Stream for real-time video and audio
   • Implement client-side logic for creating and managing video calls

Detailed Implementation

Sidebar Creation

• Categories: Home, Upcoming Meetings, Previous Meetings, Recordings, Personal Room
• Icons and navigation links designed for each category
• Active state indication for current route

Clerk Authentication Integration

• Free for up to 10,000 monthly active users
• Integrated with Next.js for seamless user experience
• Sign up/Signin management through Clerk, fully customizable

Stream Video Integration

• Setting up Stream API client and configurations
• Creating video calls and joining them
• Real-time experiences powered by Stream's APIs

Meetings Management

Home Page Cards

• New Meeting: Initiate an instant meeting
  • Schedule Meeting: Plan future meetings
  • View Recordings: Access past meeting recordings
  • Join Meeting: Join by entering a meeting link

Meeting Setup and Room

• Preview and adjust camera/microphone before joining
  • Dynamic layout options (grid, speaker view)
  • Controls for muting, screen sharing, and ending the call

Deploying the Application

• Hosted on Vercel for seamless deployment from GitHub repository
• Configuration of environment variables for production
• Ensuring the application works in a deployed environment

Final Testing and Quality Assurance

• Test and debug interactions between multiple participants
• Verify features like layout changes, screen sharing, and recording
• Ensure real-time responsiveness and scalability
