Production Deployment Guide

This guide covers deploying vuer-rtc applications to production environments, including client deployment, server deployment, database setup, and scaling considerations.

Overview

A production vuer-rtc deployment consists of:

Client Application: Static site (React/Next.js) deployed to CDN/edge network
RTC Server: Node.js server with WebSocket support
MongoDB: Replica set for Change Streams (minimum 1 node)
Redis: For pub/sub and session management
SSL/TLS: Required for secure WebSocket connections

1. Client Deployment

The client is a static site that can be deployed to any CDN or edge network.

Netlify Deployment

Setup:

Install Netlify CLI:
bash
```
npm i -g netlify-cli
```

Configure netlify.toml:

toml

[build]
  command = "pnpm build"
  publish = "dist"

[build.environment]
  NODE_VERSION = "20"

[[redirects]]
  from = "/*"
  to = "/index.html"
  status = 200

Set environment variables in Netlify dashboard or CLI:

bash

netlify env:set VITE_RTC_SERVER_URL "https://api.your-domain.com"
netlify env:set VITE_RTC_SERVER_WS "wss://api.your-domain.com"

Deploy:
bash
```
netlify deploy --prod
```

2. Server Deployment

The RTC server requires WebSocket support and persistent connections.

Railway Deployment

Railway offers excellent WebSocket support and automatic scaling.

Setup:

Install Railway CLI:
bash
```
npm i -g @railway/cli
```

  },
  "deploy": {
    "startCommand": "cd packages/vuer-rtc-server && pnpm start",
    "healthcheckPath": "/health",
    "healthcheckTimeout": 300
  }
}

Set environment variables:

bash

railway variables set MONGODB_URI="mongodb+srv://..."
railway variables set REDIS_URL="redis://..."
railway variables set NODE_ENV="production"
railway variables set CORS_ORIGIN="https://your-app.netlify.app"

      }
    }
  ]
}

Fly.io Deployment

Setup:

Install Fly CLI:
bash
```
curl -L https://fly.io/install.sh | sh
```

Create fly.toml:

toml

app = "vuer-rtc-server"
primary_region = "sjc"

fly secrets set MONGODB_URI="mongodb+srv://..."
fly secrets set REDIS_URL="redis://..."
fly secrets set CORS_ORIGIN="https://your-app.com"

Deploy:
bash
```
fly deploy
```

3. MongoDB Atlas Setup

MongoDB Atlas provides managed MongoDB with built-in replica sets.

Setup Steps:

Create Cluster:
- Go to cloud.mongodb.com
- Create a new cluster (M0 free tier works for development)
- Choose region closest to your server

Configure Network Access:

Security → Network Access → Add IP Address
- Add your server's IP or 0.0.0.0/0 (for Railway/Render)

Create Database User:

Security → Database Access → Add New Database User
- Username: vuer-rtc
- Password: (auto-generate)
- Database User Privileges: Read and write to any database

Get Connection String:

Deployment → Database → Connect → Connect your application

Example connection string:

mongodb+srv://vuer-rtc:PASSWORD@cluster0.xxxxx.mongodb.net/vuer-rtc?retryWrites=true&w=majority&replicaSet=atlas-xxxxx-shard-0

Important: Atlas clusters are automatically configured as replica sets!

Create Indexes (Optional but recommended):

javascript

// In mongosh or Compass
use vuer-rtc

// Document indexes
db.Document.createIndex({ "sceneId": 1 })
db.Document.createIndex({ "updatedAt": -1 })

// Operation indexes
db.Operation.createIndex({ "documentId": 1, "lamportTime": 1 })
db.Operation.createIndex({ "sessionId": 1 })

// Session indexes
db.Session.createIndex({ "sceneId": 1, "connected": 1 })
db.Session.createIndex({ "expiresAt": 1 }, { expireAfterSeconds: 0 })

Environment Variable:

bash

MONGODB_URI="mongodb+srv://vuer-rtc:PASSWORD@cluster0.xxxxx.mongodb.net/vuer-rtc?retryWrites=true&w=majority&replicaSet=atlas-xxxxx-shard-0"

4. Redis Cloud Setup

Redis Cloud provides managed Redis with persistence and high availability.

Setup Steps:

Create Database:
- Go to redis.com/try-free
- Create a free 30MB database
- Choose region closest to your server

Get Connection String:

Databases → Your Database → Configuration

Example:

redis://default:PASSWORD@redis-12345.c123.us-east-1-1.ec2.cloud.redislabs.com:12345

Configure Persistence (Optional):

Databases → Configuration → Data Persistence
- Enable AOF (Append Only File) for durability

Environment Variable:

bash

REDIS_URL="redis://default:PASSWORD@redis-12345.c123.us-east-1-1.ec2.cloud.redislabs.com:12345"

Alternative: Upstash (Serverless Redis)

bash

# Free tier: 10,000 commands/day
REDIS_URL="redis://default:PASSWORD@us1-example-12345.upstash.io:6379"

5. Environment Variables Checklist

Client (.env.production)

bash

# RTC Server URLs
VITE_RTC_SERVER_URL=https://api.your-domain.com
VITE_RTC_SERVER_WS=wss://api.your-domain.com

# Optional: Analytics, monitoring
VITE_SENTRY_DSN=https://...

Server (.env.production)

bash

# Database
MONGODB_URI=mongodb+srv://user:pass@cluster.mongodb.net/vuer-rtc?replicaSet=...
REDIS_URL=redis://default:pass@redis.example.com:6379

# Server
NODE_ENV=production
PORT=3000

# CORS (comma-separated)
CORS_ORIGIN=https://app.example.com,https://www.app.example.com

# Optional: Session management
SESSION_TTL=86400        # 24 hours in seconds
MAX_CONNECTIONS=1000     # Max concurrent WebSocket connections

# Optional: Monitoring
SENTRY_DSN=https://...
LOG_LEVEL=info

# Optional: Security
JWT_SECRET=your-secret-key
RATE_LIMIT_WINDOW=60000  # 1 minute
RATE_LIMIT_MAX=100       # 100 requests per window

6. CORS Configuration for WebSockets

WebSocket connections require proper CORS configuration.

Server Configuration (Fastify):

typescript

import Fastify from 'fastify';
import cors from '@fastify/cors';
import websocket from '@fastify/websocket';

const app = Fastify({ logger: true });

// CORS for HTTP endpoints
await app.register(cors, {
  origin: process.env.CORS_ORIGIN?.split(',') || ['http://localhost:5173'],
  credentials: true,
  methods: ['GET', 'POST', 'PUT', 'DELETE', 'OPTIONS'],
});

// WebSocket with origin checking
await app.register(websocket, {
  options: {
    verifyClient: (info, callback) => {
      const origin = info.origin || info.req.headers.origin;
      const allowedOrigins = process.env.CORS_ORIGIN?.split(',') || [];

      if (allowedOrigins.includes(origin)) {
        callback(true);
      } else {
        callback(false, 403, 'Origin not allowed');
      }
    },
  },
});

Client Configuration:

typescript

import { RTCClient } from '@vuer-ai/vuer-rtc';

const client = new RTCClient({
  serverUrl: import.meta.env.VITE_RTC_SERVER_URL,
  wsUrl: import.meta.env.VITE_RTC_SERVER_WS,
  // Credentials are sent automatically by the browser
});

7. SSL/TLS for WebSocket Connections

Production WebSocket connections must use WSS (WebSocket Secure).

Automatic SSL (Recommended)

Most platforms handle SSL automatically:

Platform	SSL Setup
Railway	Automatic SSL via Railway domains or custom domains
Render	Automatic SSL via Let's Encrypt
Fly.io	Automatic SSL via Let's Encrypt
Netlify	Automatic SSL for all deployments

Manual SSL (Nginx + Let's Encrypt)

If self-hosting, use Nginx as a reverse proxy:

Install Certbot:

bash

sudo apt-get update
sudo apt-get install certbot python3-certbot-nginx

Nginx Configuration (/etc/nginx/sites-available/vuer-rtc):

nginx

upstream vuer_rtc_server {
    server localhost:3000;
}

server {
    listen 80;
    server_name api.your-domain.com;

    # Redirect to HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name api.your-domain.com;

    # SSL certificates (managed by Certbot)
    ssl_certificate /etc/letsencrypt/live/api.your-domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/api.your-domain.com/privkey.pem;

    # SSL configuration
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;

    # WebSocket upgrade
    location / {
        proxy_pass http://vuer_rtc_server;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        # WebSocket timeouts
        proxy_read_timeout 86400s;
        proxy_send_timeout 86400s;
    }
}

Enable and get certificate:

bash

sudo ln -s /etc/nginx/sites-available/vuer-rtc /etc/nginx/sites-enabled/
sudo certbot --nginx -d api.your-domain.com
sudo systemctl restart nginx

Auto-renewal:

bash

sudo certbot renew --dry-run

8. Scaling Considerations

Horizontal Scaling

Use Redis Pub/Sub to synchronize state across multiple server instances.

Architecture:

┌─────────────┐    ┌─────────────┐    ┌─────────────┐
│  Server 1   │    │  Server 2   │    │  Server 3   │
│  (Node.js)  │    │  (Node.js)  │    │  (Node.js)  │
└──────┬──────┘    └──────┬──────┘    └──────┬──────┘
       │                  │                  │
       └──────────────────┼──────────────────┘
                          │
                   ┌──────▼──────┐
                   │    Redis    │
                   │  (Pub/Sub)  │
                   └─────────────┘

Implementation:

typescript

import Redis from 'ioredis';

class ScalableRTCServer {
  private redis: Redis;
  private subscriber: Redis;

  constructor() {
    this.redis = new Redis(process.env.REDIS_URL);
    this.subscriber = new Redis(process.env.REDIS_URL);

    // Subscribe to broadcast channel
    this.subscriber.subscribe('rtc:broadcast');
    this.subscriber.on('message', (channel, message) => {
      const { sceneId, msg, senderId } = JSON.parse(message);
      this.broadcastToLocal(sceneId, msg, senderId);
    });
  }

  handleMessage(sceneId: string, msg: CRDTMessage, senderId: string) {
    // Process locally
    this.processMessage(sceneId, msg);

    // Broadcast to other servers via Redis
    this.redis.publish('rtc:broadcast', JSON.stringify({
      sceneId,
      msg,
      senderId,
    }));
  }

  private broadcastToLocal(sceneId: string, msg: CRDTMessage, senderId: string) {
    // Send to local clients only (excluding sender)
    const clients = this.getLocalClients(sceneId);
    for (const client of clients) {
      if (client.id !== senderId) {
        client.send(JSON.stringify({ mtype: 'message', msg }));
      }
    }
  }
}

Load Balancing

Railway/Render: Automatic load balancing with multiple instances

AWS ALB Configuration:

json

{
  "Type": "application",
  "Scheme": "internet-facing",
  "TargetType": "ip",
  "HealthCheck": {
    "Path": "/health",
    "Protocol": "HTTP",
    "Interval": 30,
    "Timeout": 5,
    "HealthyThreshold": 2,
    "UnhealthyThreshold": 3
  },
  "Stickiness": {
    "Enabled": true,
    "Type": "lb_cookie",
    "DurationSeconds": 86400
  }
}

Important: Enable sticky sessions (session affinity) for WebSocket connections!

Database Scaling

MongoDB Atlas:

M0 (Free)       → 512MB, shared CPU     → Development
M10 ($57/mo)    → 2GB, dedicated        → Small production
M30 ($237/mo)   → 8GB, dedicated        → Medium production
M50+ (Custom)   → 16GB+, auto-scaling   → Large production

Sharding (Advanced):

javascript

// Enable sharding for large-scale deployments
sh.enableSharding("vuer-rtc")
sh.shardCollection("vuer-rtc.operations", { "documentId": 1, "lamportTime": 1 })

9. Health Checks and Monitoring

Health Check Endpoint

typescript

// packages/vuer-rtc-server/src/routes/health.ts
import { FastifyInstance } from 'fastify';

export async function healthRoutes(app: FastifyInstance) {
  app.get('/health', async (request, reply) => {
    const mongoOk = await checkMongo();
    const redisOk = await checkRedis();

    const status = mongoOk && redisOk ? 200 : 503;

    return reply.status(status).send({
      status: status === 200 ? 'healthy' : 'unhealthy',
      timestamp: new Date().toISOString(),
      services: {
        mongo: mongoOk ? 'up' : 'down',
        redis: redisOk ? 'up' : 'down',
      },
    });
  });

  app.get('/metrics', async (request, reply) => {
    return {
      connections: app.websocketServer.clients.size,
      uptime: process.uptime(),
      memory: process.memoryUsage(),
    };
  });
}

async function checkMongo(): Promise<boolean> {
  try {
    await prisma.$queryRaw`SELECT 1`;
    return true;
  } catch {
    return false;
  }
}

async function checkRedis(): Promise<boolean> {
  try {
    await redis.ping();
    return true;
  } catch {
    return false;
  }
}

Monitoring with Sentry

Install:

bash

pnpm add @sentry/node @sentry/profiling-node

Setup:

typescript

import * as Sentry from '@sentry/node';
import { ProfilingIntegration } from '@sentry/profiling-node';

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  environment: process.env.NODE_ENV,
  integrations: [
    new ProfilingIntegration(),
  ],
  tracesSampleRate: 0.1,
  profilesSampleRate: 0.1,
});

// Error handling
app.setErrorHandler((error, request, reply) => {
  Sentry.captureException(error);
  reply.status(500).send({ error: 'Internal Server Error' });
});

Logging

typescript

import pino from 'pino';

const logger = pino({
  level: process.env.LOG_LEVEL || 'info',
  transport: process.env.NODE_ENV === 'development' ? {
    target: 'pino-pretty',
    options: { colorize: true }
  } : undefined,
});

// Log WebSocket events
ws.on('message', (data) => {
  logger.info({ type: 'ws:message', size: data.length }, 'Received message');
});

ws.on('error', (error) => {
  logger.error({ err: error }, 'WebSocket error');
});

10. Backup and Disaster Recovery

MongoDB Backup

Automated Backups (Atlas):

Atlas provides automatic daily backups with point-in-time recovery:

Deployment → Backup → Configure
- Cloud Provider: AWS/GCP/Azure
- Backup Policy: Daily snapshots + continuous backups
- Retention: 1-7 days (free tier) or custom

Manual Backup:

bash

# Export database
mongodump --uri="mongodb+srv://..." --out=/backup/$(date +%Y%m%d)

# Restore
mongorestore --uri="mongodb+srv://..." /backup/20260227

Backup Strategy:

bash

#!/bin/bash
# backup.sh - Run daily via cron

BACKUP_DIR="/backups/vuer-rtc"
DATE=$(date +%Y%m%d_%H%M%S)
RETENTION_DAYS=7

# Create backup
mongodump --uri="${MONGODB_URI}" --out="${BACKUP_DIR}/${DATE}"

# Compress
tar -czf "${BACKUP_DIR}/${DATE}.tar.gz" -C "${BACKUP_DIR}" "${DATE}"
rm -rf "${BACKUP_DIR}/${DATE}"

# Delete old backups
find "${BACKUP_DIR}" -name "*.tar.gz" -mtime +${RETENTION_DAYS} -delete

# Upload to S3 (optional)
aws s3 cp "${BACKUP_DIR}/${DATE}.tar.gz" "s3://your-bucket/backups/"

Cron job:

bash

0 2 * * * /usr/local/bin/backup.sh >> /var/log/vuer-rtc-backup.log 2>&1

Redis Backup

Redis Cloud: Automatic daily backups

Manual Backup:

bash

# Snapshot
redis-cli --rdb /backup/redis/dump-$(date +%Y%m%d).rdb

# Restore
cp /backup/redis/dump-20260227.rdb /var/lib/redis/dump.rdb
systemctl restart redis

Disaster Recovery Plan

Regular Backups:
- MongoDB: Daily automated backups via Atlas
- Redis: Daily snapshots
- Code: GitHub repository

Recovery Procedures:

bash

# 1. Restore MongoDB
mongorestore --uri="${MONGODB_URI}" /backup/latest

# 2. Restore Redis
redis-cli --rdb /backup/redis/dump.rdb

# 3. Redeploy server
railway up  # or your deployment command

# 4. Verify health
curl https://api.your-domain.com/health

Failover Strategy:
- Use MongoDB Atlas automatic failover
- Deploy to multiple regions (Railway/Render supports this)
- Implement circuit breakers in client code

Testing:

bash

# Test restore quarterly
mongorestore --uri="${TEST_MONGODB_URI}" /backup/latest
# Verify data integrity

Monitoring Alerts

Setup alerts for:

Server downtime (health check failures)
High memory/CPU usage (>80%)
Database connection failures
WebSocket connection spikes
High error rates (>1% of requests)

Example (Railway):

bash

# Railway automatically monitors uptime
# Configure alerts in Settings → Notifications

Example (Sentry):

javascript

Sentry.init({
  beforeSend(event, hint) {
    // Alert on critical errors
    if (event.level === 'fatal') {
      // Trigger PagerDuty/Slack/email alert
    }
    return event;
  },
});

Quick Start Checklist

Troubleshooting

WebSocket Connection Fails

Symptoms: Client cannot connect, "WebSocket connection failed" error

Solutions:

Check CORS:

bash

# Test from browser console
new WebSocket('wss://api.your-domain.com')

Verify SSL:

bash

openssl s_client -connect api.your-domain.com:443

Check server logs:

bash

railway logs  # or your platform's log command

MongoDB Replica Set Error

Symptoms: MongoServerError: The command requires replica set

Solution: Ensure connection string includes replicaSet parameter:

mongodb+srv://...?replicaSet=atlas-xxxxx-shard-0

High Latency

Symptoms: Slow updates, delayed synchronization

Solutions:

Check region proximity:
- Deploy server close to MongoDB cluster
- Use same cloud provider for server and database

Enable connection pooling:

typescript

const prisma = new PrismaClient({
  datasources: {
    db: {
      url: process.env.MONGODB_URI,
    },
  },
  // Increase pool size
  pool: {
    min: 5,
    max: 20,
  },
});

Optimize queries:

typescript

// Add indexes
db.Operation.createIndex({ documentId: 1, lamportTime: 1 })

Memory Leaks

Symptoms: Increasing memory usage over time

Solutions:

Monitor with metrics:

bash

curl https://api.your-domain.com/metrics

Clean up stale connections:

typescript

setInterval(() => {
  for (const [id, ws] of connections) {
    if (ws.readyState === WebSocket.CLOSED) {
      connections.delete(id);
    }
  }
}, 60000); // Every minute

Limit journal size:

typescript

if (journal.length > 10000) {
  journal = journal.slice(-5000); // Keep last 5000 entries
}
