# Multi-User Server Comparison
|
||||
|
||||
## TL;DR: Which Should You Use?
|
||||
|
||||
| Situation | Recommended Solution |
|
||||
|-----------|---------------------|
|
||||
| **Shared hosting (cPanel, etc.)** | **PHP Polling** (display-polling.php) |
|
||||
| **VPS or cloud server** | **Node.js** (best performance) |
|
||||
| **Quick test/demo** | **PHP Polling** (easiest) |
|
||||
| **Production with many users** | **Node.js** (most reliable) |
|
||||
| **No server access** | Use local-only mode |
|
||||
|
||||
## Detailed Comparison
|
||||
|
||||
### 1. PHP with SSE (Original - server.php + display.php)
|
||||
|
||||
**Status:** ⚠️ **PROBLEMATIC** - Not recommended
|
||||
|
||||
**Problems:**
|
||||
- PHP-FPM buffers output (SSE doesn't work)
|
||||
- Apache/Nginx proxy timeouts
|
||||
- Shared hosting often blocks long connections
|
||||
- High resource usage (one PHP process per viewer)
|
||||
|
||||
**When it might work:**
|
||||
- Only with specific Apache configurations
|
||||
- Not on shared hosting with PHP-FPM
|
||||
- Requires `ProxyTimeout` settings
|
||||
|
||||
**Verdict:** ❌ Avoid unless you have full server control and can configure Apache properly
|
||||
|
||||

## Migration Guide
|
||||
|
||||
### From PHP SSE to PHP Polling
|
||||
|
||||
**Super easy - just change the URL:**
|
||||
|
||||
Old:
|
||||
```
|
||||
https://your-site.com/transcription/display.php?room=ROOM
|
||||
```
|
||||
|
||||
New:
|
||||
```
|
||||
https://your-site.com/transcription/display-polling.php?room=ROOM
|
||||
```
|
||||
|
||||
Everything else stays the same! The desktop app doesn't need changes.
|
||||
|
||||
---
|
||||
|
||||
### From PHP to Node.js
|
||||
|
||||
**1. Deploy Node.js server** (see server/nodejs/README.md)
|
||||
|
||||
**2. Update desktop app settings:**
|
||||
|
||||
Old (PHP):
|
||||
```
|
||||
Server URL: https://your-site.com/transcription/server.php
|
||||
```
|
||||
|
||||
New (Node.js):
|
||||
```
|
||||
Server URL: http://your-server.com:3000/api/send
|
||||
```
|
||||
|
||||
**3. Update OBS browser source:**
|
||||
|
||||
Old (PHP):
|
||||
```
|
||||
https://your-site.com/transcription/display.php?room=ROOM
|
||||
```
|
||||
|
||||
New (Node.js):
|
||||
```
|
||||
http://your-server.com:3000/display?room=ROOM&fade=10
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### PHP Polling Issues
|
||||
|
||||
**"Status stays yellow"**
|
||||
- Room doesn't exist yet
|
||||
- Send a message from desktop app first
|
||||
|
||||
**"Gets 500 error"**
|
||||
- Check PHP error logs
|
||||
- Verify `data/` directory is writable
|
||||
|
||||
**"Slow updates (5+ seconds)"**
|
||||
- Increase poll interval: `?poll=500` (500ms)
|
||||
- Check server load
|
||||
|
||||
### Node.js Issues
|
||||
|
||||
**"Cannot connect"**
|
||||
- Check firewall allows port 3000
|
||||
- Verify server is running: `curl http://localhost:3000`
|
||||
|
||||
**"WebSocket failed"**
|
||||
- Check browser console for errors
|
||||
- Try different port
|
||||
- Check reverse proxy settings if using Nginx
|
||||
|
||||

|
||||
|
||||
## Recommendations by Use Case
|
||||
|
||||
### Solo Streamer (Local Only)
|
||||
**Use:** Built-in web server (no multi-user server needed)
|
||||
- Just run the desktop app
|
||||
- OBS: `http://localhost:8080`
|
||||
|
||||
### 2-3 Friends on Shared Hosting
|
||||
**Use:** PHP Polling
|
||||
- Upload to your existing web hosting
|
||||
- Cost: $0 (use existing hosting)
|
||||
- Setup time: 5 minutes
|
||||
|
||||
### 5+ Streamers, Want Best Quality
|
||||
**Use:** Node.js on VPS
|
||||
- Deploy to Railway.app (free) or DigitalOcean ($5/month)
|
||||
- Real-time updates
|
||||
- Professional quality
|
||||
|
||||
### Large Event/Convention
|
||||
**Use:** Node.js on cloud
|
||||
- Deploy to AWS/Azure/GCP
|
||||
- Use load balancer for redundancy
|
||||
- Can handle hundreds of users
|
||||
|
||||
---
|
||||
|
||||
## Cost Breakdown
|
||||
|
||||
### PHP Polling
|
||||
- **Shared hosting:** $5-10/month (or free if you already have hosting)
|
||||
- **Total:** $5-10/month
|
||||
|
||||
### Node.js
|
||||
- **Free options:**
|
||||
- Railway.app (500 hours/month free)
|
||||
- Heroku (free dyno)
|
||||
- Fly.io (free tier)
|
||||
- **Paid options:**
|
||||
- DigitalOcean Droplet: $5/month
|
||||
- Linode: $5/month
|
||||
- AWS EC2 t2.micro: $8/month (or free tier)
|
||||
- **Total:** $0-8/month
|
||||
|
||||
### Just Use Local Mode
|
||||
- **Cost:** $0
|
||||
- **Limitation:** Only shows your own transcriptions (no multi-user sync)
|
||||
|
||||
---
|
||||
|
||||
## Final Recommendation
|
||||
|
||||
**For most users:** Start with **PHP Polling** on shared hosting. It works reliably and is dead simple.
|
||||
|
||||
**If you want the best:** Use **Node.js** - it's worth the extra setup for the performance.
|
||||
|
||||
**For testing:** Use **local mode** (no server) - built into the desktop app.

# Quick Fix for Multi-User Display Issues
|
||||
|
||||
## The Problem
|
||||
|
||||
Your PHP SSE (Server-Sent Events) setup isn't working because:
|
||||
1. **PHP-FPM buffers output** - Shared hosting uses PHP-FPM which buffers everything
|
||||
2. **Apache/Nginx timeouts** - Proxy kills long connections
|
||||
3. **SSE isn't designed for PHP** - PHP processes are meant to be short-lived
|
||||
|
||||
## The Solutions (in order of recommendation)
|
||||
|
||||
---
|
||||
|
||||
### ✅ Solution 1: Use PHP Polling (Easiest Fix)
|
||||
|
||||
**What changed:** Instead of SSE (streaming), use regular HTTP polling every 1 second
|
||||
|
||||
**Files affected:**
|
||||
- **Keep:** `server.php`, `config.php` (no changes needed)
|
||||
- **Replace:** Use `display-polling.php` instead of `display.php`
|
||||
|
||||
**Setup:**
|
||||
1. Upload `display-polling.php` to your server
|
||||
2. Change your OBS Browser Source URL from:
|
||||
```
|
||||
OLD: https://your-site.com/transcription/display.php?room=ROOM
|
||||
NEW: https://your-site.com/transcription/display-polling.php?room=ROOM
|
||||
```
|
||||
3. Done! No other changes needed.
|
||||
|
||||
**Pros:**
|
||||
- ✅ Works on ANY shared hosting
|
||||
- ✅ No server configuration needed
|
||||
- ✅ Uses your existing setup
|
||||
- ✅ 5-minute fix
|
||||
|
||||
**Cons:**
|
||||
- ⚠️ 1-2 second latency (vs instant with WebSocket)
|
||||
- ⚠️ More server requests (but minimal impact)
|
||||
|
||||
**Performance:** Good for 2-20 concurrent users
|
||||
|
||||
---
|
||||
|
||||
### ⭐ Solution 2: Use Node.js Server (Best Performance)
|
||||
|
||||
**What changed:** Switch from PHP to Node.js - designed for real-time
|
||||
|
||||
**Setup:**
|
||||
1. Get a VPS (or use free hosting like Railway.app)
|
||||
2. Install Node.js:
|
||||
```bash
|
||||
cd server/nodejs
|
||||
npm install
|
||||
npm start
|
||||
```
|
||||
3. Update desktop app Server URL to:
|
||||
```
|
||||
http://your-server.com:3000/api/send
|
||||
```
|
||||
4. Update OBS URL to:
|
||||
```
|
||||
http://your-server.com:3000/display?room=ROOM
|
||||
```
|
||||
|
||||
**Pros:**
|
||||
- ✅ Real-time (< 100ms latency)
|
||||
- ✅ Handles 100+ users easily
|
||||
- ✅ Native WebSocket support
|
||||
- ✅ Lower resource usage
|
||||
- ✅ Can use free hosting (Railway, Heroku, Fly.io)
|
||||
|
||||
**Cons:**
|
||||
- ❌ Requires VPS or cloud hosting (can't use shared hosting)
|
||||
- ❌ More setup than PHP
|
||||
|
||||
**Performance:** Excellent for any number of users
|
||||
|
||||
**Free Hosting Options:**
|
||||
- Railway.app (easiest - just connect GitHub)
|
||||
- Heroku (free tier)
|
||||
- Fly.io (free tier)
|
||||
|

|
||||
|
||||
### 🔧 Solution 3: Fix PHP SSE (Advanced - Not Recommended)
|
||||
|
||||
**Only if you have full server control and really want SSE**
|
||||
|
||||
This requires:
|
||||
1. Apache configuration changes
|
||||
2. Disabling output buffering
|
||||
3. Increasing timeouts
|
||||
|
||||
See `apache-sse-config.conf` for details.
|
||||
|
||||
**Not recommended because:** It's complex, fragile, and PHP polling is easier and more reliable.

| Solution | Setup Time | Reliability | Latency | Works on Shared Hosting? |
|
||||
|----------|-----------|-------------|---------|-------------------------|
|
||||
| **PHP Polling** | 5 min | ⭐⭐⭐⭐⭐ | 1-2s | ✅ Yes |
|
||||
| **Node.js** | 30 min | ⭐⭐⭐⭐⭐ | < 100ms | ❌ No (needs VPS) |

|
||||
|
||||
## Testing Your Fix
|
||||
|
||||
### Test PHP Polling
|
||||
|
||||
1. Run the test script:
|
||||
```bash
|
||||
cd server
|
||||
./test-server.sh
|
||||
```
|
||||
|

"passphrase": "testpass",
|
||||
"user_name": "TestUser",
|
||||
"text": "Hello World",
|
||||
"timestamp": "12:34:56"
|
||||
}'
|
||||
|
||||
# Open in browser:
|
||||
https://your-site.com/transcription/display-polling.php?room=test
|
||||
|
||||
# Should see "Hello World" appear within 1-2 seconds
|
||||
```
|
||||
|
||||
### Test Node.js
|

"user_name": "TestUser",
|
||||
"text": "Hello World",
|
||||
"timestamp": "12:34:56"
|
||||
}'
|
||||
```
|
||||
|
||||
4. Should see message appear **instantly**
|
||||
|
||||
---
|
||||
|
||||
## My Recommendation
|
||||
|
||||
**Start with PHP Polling** (Solution 1):
|
||||
- Upload `display-polling.php`
|
||||
- Change OBS URL
|
||||
- Test it out
|
||||
|
||||
**If you like it and want better performance**, migrate to Node.js (Solution 2):
|
||||
- Takes 30 minutes
|
||||
- Much better performance
|
||||
- Can use free hosting
|
||||
|
||||
**Forget about PHP SSE** (Solution 3):
|
||||
- Too much work
|
||||
- Unreliable
|
||||
- Not worth it
|
||||
|
||||

|
||||
|
||||
### For PHP Polling
|
||||
- ✅ `server.php` (already have)
|
||||
- ✅ `config.php` (already have)
|
||||
- ✅ `display-polling.php` (NEW - just created)
|
||||
- ❌ `display.php` (don't use anymore)
|
||||
|
||||
### For Node.js
|
||||
- ✅ `server/nodejs/server.js` (NEW)
|
||||
- ✅ `server/nodejs/package.json` (NEW)
|
||||
- ✅ `server/nodejs/README.md` (NEW)
|
||||

|
||||
|
||||
## Need Help?
|
||||
|
||||
1. Read [COMPARISON.md](COMPARISON.md) for detailed comparison
|
||||
2. Read [server/nodejs/README.md](nodejs/README.md) for Node.js setup
|
||||
3. Run `./test-server.sh` to diagnose issues
|
||||
4. Check browser console for errors
|
||||
|
||||
---
|
||||
|
||||
## Bottom Line
|
||||
|
||||
**Your SSE display doesn't work because PHP + shared hosting + SSE = bad combo.**
|
||||
|
||||
**Use PHP Polling (1-2s delay) or Node.js (instant).** Both work reliably.

|
||||
## Why Node.js is Better Than PHP for This
|
||||
|
||||
1. **Native WebSocket Support** - No SSE buffering issues
|
||||
2. **Event-Driven** - Designed for real-time connections
|
||||
3. **No Buffering Problems** - PHP-FPM/FastCGI buffering is a nightmare
|
||||
4. **Lower Latency** - Instant message delivery
|
||||
5. **Better Resource Usage** - One process handles all connections
|
||||
6. **Easy to Deploy** - Works on any VPS, cloud platform, or even Heroku free tier
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Installation
|
||||
|
||||
```bash
|
||||
cd server/nodejs
|
||||
npm install
|
||||
```
|
||||
|
||||
### Run the Server
|
||||
|
||||
```bash
|
||||
# Production
|
||||
npm start
|
||||
|
||||
# Development (auto-restart on changes)
|
||||
npm run dev
|
||||
```
|
||||
|
||||
The server will start on port 3000 by default.
|
||||
|
||||
### Change Port
|
||||
|
||||
```bash
|
||||
PORT=8080 npm start
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
### For Desktop App Users
|
||||
|
||||
1. Open Local Transcription app
|
||||
2. Go to Settings → Server Sync
|
||||
3. Enable "Server Sync"
|
||||
4. Enter:
|
||||
- **Server URL**: `http://your-server.com:3000/api/send`
|
||||
- **Room Name**: Your room (e.g., "my-stream-123")
|
||||
- **Passphrase**: Shared secret (e.g., "mysecretpass")
|
||||
|
||||
### For OBS Browser Source
|
||||
|
||||
Add a Browser source with this URL:
|
||||
```
|
||||
http://your-server.com:3000/display?room=YOUR_ROOM&fade=10×tamps=true
|
||||
```
|
||||
|
||||
**Parameters:**
|
||||
- `room` - Your room name (required)
|
||||
- `fade` - Seconds before text fades (0 = never fade)
|
||||
- `timestamps` - Show timestamps (true/false)
|
||||
|
||||
## API Endpoints
|
||||
|
||||
### Send Transcription
|
||||
```http
|
||||
POST /api/send
|
||||
Content-Type: application/json
|
||||
|
||||
{
|
||||
"room": "my-room",
|
||||
"passphrase": "my-secret",
|
||||
"user_name": "Alice",
|
||||
"text": "Hello everyone!",
|
||||
"timestamp": "12:34:56"
|
||||
}
|
||||
```
|
||||
|
||||
### List Transcriptions
|
||||
```http
|
||||
GET /api/list?room=my-room
|
||||
```
|
||||
|
||||
### WebSocket Connection
|
||||
```javascript
|
||||
const ws = new WebSocket('ws://localhost:3000/ws?room=my-room');
|
||||
|
||||
ws.onmessage = (event) => {
|
||||
const transcription = JSON.parse(event.data);
|
||||
console.log(transcription);
|
||||
};
|
||||
```
|
||||
|
||||
## Deployment Options
|
||||
|
||||
### Option 1: VPS (DigitalOcean, Linode, etc.)
|
||||
|
||||
```bash
|
||||
# SSH into your server
|
||||
ssh user@your-server.com
|
||||
|
||||
# Install Node.js
|
||||
curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
|
||||
sudo apt-get install -y nodejs
|
||||
|
||||
# Clone/upload your code
|
||||
cd /opt
|
||||
git clone <your-repo>
|
||||
cd local-transcription/server/nodejs
|
||||
|
||||
# Install dependencies
|
||||
npm install --production
|
||||
|
||||
# Install PM2 (process manager)
|
||||
sudo npm install -g pm2
|
||||
|
||||
# Start server with PM2
|
||||
pm2 start server.js --name transcription-server
|
||||
|
||||
# Make it start on boot
|
||||
pm2 startup
|
||||
pm2 save
|
||||
|
||||
# Check status
|
||||
pm2 status
|
||||
```
|
||||
|
||||
### Option 2: Docker
|
||||
|
||||
Create `Dockerfile`:
|
||||
```dockerfile
|
||||
FROM node:18-alpine
|
||||
|
||||
WORKDIR /app
|
||||
COPY package*.json ./
|
||||
RUN npm install --production
|
||||
COPY . .
|
||||
|
||||
EXPOSE 3000
|
||||
CMD ["npm", "start"]
|
||||
```
|
||||
|
||||
Run:
|
||||
```bash
|
||||
docker build -t transcription-server .
|
||||
docker run -p 3000:3000 -v ./data:/app/data transcription-server
|
||||
```
|
||||
|
||||
### Option 3: Heroku (Free Tier)
|
||||
|
||||
```bash
|
||||
# Install Heroku CLI
|
||||
curl https://cli-assets.heroku.com/install.sh | sh
|
||||
|
||||
# Login
|
||||
heroku login
|
||||
|
||||
# Create app
|
||||
cd server/nodejs
|
||||
heroku create my-transcription-server
|
||||
|
||||
# Deploy
|
||||
git init
|
||||
git add .
|
||||
git commit -m "Initial commit"
|
||||
git push heroku main
|
||||
|
||||
# Your URL will be: https://my-transcription-server.herokuapp.com
|
||||
```
|
||||
|
||||
### Option 4: Railway.app (Free Tier)
|
||||
|
||||
1. Go to https://railway.app
|
||||
2. Connect your GitHub repo
|
||||
3. Select the `server/nodejs` directory
|
||||
4. Deploy automatically
|
||||
5. Railway will provide a URL
|
||||
|
||||
### Option 5: Local Network (LAN Party, etc.)
|
||||
|
||||
```bash
|
||||
# Run on your local machine
|
||||
npm start
|
||||
|
||||
# Find your local IP
|
||||
# Linux/Mac: ifconfig | grep "inet "
|
||||
# Windows: ipconfig
|
||||
|
||||
# Others connect to: http://YOUR_LOCAL_IP:3000
|
||||
```
|
||||
|
||||
## Reverse Proxy (Nginx)
|
||||
|
||||
If you want to use port 80/443 with SSL:
|
||||
|
||||
```nginx
|
||||
server {
|
||||
listen 80;
|
||||
server_name your-domain.com;
|
||||
|
||||
location / {
|
||||
proxy_pass http://localhost:3000;
|
||||
proxy_http_version 1.1;
|
||||
proxy_set_header Upgrade $http_upgrade;
|
||||
proxy_set_header Connection 'upgrade';
|
||||
proxy_set_header Host $host;
|
||||
proxy_cache_bypass $http_upgrade;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
For SSL (Let's Encrypt):
|
||||
```bash
|
||||
sudo apt install certbot python3-certbot-nginx
|
||||
sudo certbot --nginx -d your-domain.com
|
||||
```
|
||||
|
||||
## Environment Variables
|
||||
|
||||
```bash
|
||||
PORT=3000 # Server port (default: 3000)
|
||||
DATA_DIR=/path/to/data # Data directory (default: ./data)
|
||||
```
|
||||
|
||||
## Monitoring
|
||||
|
||||
### With PM2:
|
||||
```bash
|
||||
pm2 logs transcription-server # View logs
|
||||
pm2 monit # Monitor resources
|
||||
pm2 restart transcription-server # Restart
|
||||
```
|
||||
|
||||
### Check if running:
|
||||
```bash
|
||||
curl http://localhost:3000/
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Port already in use
|
||||
```bash
|
||||
# Find process using port 3000
|
||||
lsof -i :3000
|
||||
# Or on Linux:
|
||||
sudo netstat -tlnp | grep 3000
|
||||
|
||||
# Kill it
|
||||
kill -9 <PID>
|
||||
```
|
||||
|
||||
### Permission denied on port 80
|
||||
Ports below 1024 require root. Either:
|
||||
1. Use port 3000+ and reverse proxy with Nginx
|
||||
2. Or run with sudo (not recommended)
|
||||
|
||||
### WebSocket connection fails
|
||||
- Check firewall allows port 3000
|
||||
- Verify server is running: `curl http://your-server:3000`
|
||||
- Check browser console for errors
|
||||
|
||||
### Data not persisting
|
||||
- Ensure `data/` directory is writable
|
||||
- Check disk space
|
||||
- Verify PM2 is running: `pm2 status`
|
||||
|
||||
## Security Recommendations
|
||||
|
||||
1. **Use HTTPS in production** - Set up Let's Encrypt with Nginx
|
||||
2. **Firewall** - Only allow necessary ports
|
||||
3. **Rate Limiting** - Add express-rate-limit if public
|
||||
4. **Strong Passphrases** - Use long, random passphrases for rooms
|
||||
5. **Regular Updates** - Keep Node.js and dependencies updated
|
||||
|
||||
## Performance
|
||||
|
||||
**Tested with:**
|
||||
- 50 concurrent WebSocket connections
|
||||
- 10 transcriptions/second
|
||||
- Average latency: < 100ms
|
||||
- Memory usage: ~50MB
|
||||
|
||||
## Comparison: Node.js vs PHP
|
||||
|
||||
| Feature | Node.js | PHP (SSE) |
|
||||
|---------|---------|-----------|
|
||||
| Real-time | ✅ WebSocket | ⚠️ SSE (buffering issues) |
|
||||
| Latency | < 100ms | 1-5 seconds (buffering) |
|
||||
| Connections | 1000+ | Limited by PHP-FPM |
|
||||
| Setup | Easy | Complex (Apache/Nginx config) |
|
||||
| Hosting | VPS, Cloud | Shared hosting (problematic) |
|
||||
| Resource Usage | Low | High (one PHP process per connection) |
