OPNode Live Streaming Features - Complete Implementation

✅ Features Implemented

1. Real-time Viewer Count Tracking

  • How it works:

    • When a viewer joins a stream, the viewer count increments automatically
    • Updates every 30 seconds to maintain presence
    • Decrements when viewer leaves (component unmount)
    • Shows live count in the stream stats section

  • Implementation: /app/stream/[id]/page.tsx lines 60-85

2. Live Chat

  • Features:

    • Real-time message delivery via Convex
    • Username display with host badge
    • Auto-scroll to latest messages
    • Optimistic UI (messages appear instantly while sending)
    • Requires wallet connection to chat

  • How to test:

    1. Open a stream in two browser windows
    2. Connect wallet in both (or use incognito for second session)
    3. Send messages from either window
    4. Messages appear in real-time in both windows

3. Lightning Gifts/Tips ⚡

  • Full Lightning Network Integration:

    • Uses Breez SDK for spontaneous payments (keysend)
    • Sends actual Lightning payments from viewer to streamer
    • No invoices needed - direct peer-to-peer payments
    • Real-time payment verification
    • Updates stream earnings and gift count

  • How it works:

    1. Viewer clicks gift button
    2. Selects amount (quick buttons: 100, 500, 1000, 5000 sats)
    3. Payment is sent via Lightning Network to streamer's node
    4. Payment confirmation updates database
    5. Gift appears in chat with amount
    6. Stream stats update automatically

  • Requirements:

    • Viewer must have connected wallet with sufficient balance
    • Streamer must have wallet set up (public key available)
    • Both must be on same network (testnet/mainnet)

4. Stream Status Integration

  • Mux Webhook Integration:
    • Automatically updates stream status when OBS connects
    • Removes "Stream Starting Soon" overlay when live
    • Marks stream as ended when OBS disconnects

5. Enhanced UI/UX

  • Gift Modal Improvements:

    • Loading states with animated lightning bolt
    • Error handling with user-friendly messages
    • Quick amount selection buttons
    • Disabled state during processing
    • Success/failure notifications

  • Stats Display:

    • Formatted number display (e.g., "1,234 sats")
    • Null-safe rendering (shows 0 if no data)
    • Real-time updates as gifts are received

5. UI shows live count from database

🧪 Testing Guide

Test Chat:

  1. Open stream in two browsers/tabs
  2. Connect wallet in both
  3. Send messages from each
  4. Verify real-time delivery
  5. Check host badge appears for streamer

Test Gifting:

  1. Setup:

    • Ensure viewer wallet has balance
    • Verify streamer wallet is connected
    • Check both on same network

  2. Send Gift:

    • Open gift modal
    • Select amount (start with 100 sats)
    • Click "Send"
    • Watch for lightning animation
    • Verify success message

  3. Verify:

    • Gift appears in chat
    • Stream earnings increase
    • Gift count increments
    • Streamer receives payment in wallet

Test Viewer Count:

  1. Open stream (count = 1)
  2. Open in another tab (count = 2)
  3. Close one tab (count = 1)
  4. Verify count updates in remaining tab

⚠️ Error Handling

Gift Errors:

  • "Streamer hasn't set up wallet" → Streamer needs to connect wallet
  • "Recipient public key not found" → Database issue, check wallet profile
  • "Insufficient balance" → Viewer needs more sats
  • "Payment failed" → Network/node connection issue

All errors are:

  • Logged to console for debugging
  • Shown to user in modal
  • Update gift status to "failed"
  • Prevent multiple attempts during processing
