Best Practice: Isolated Environments
# Install Railway CLI
npm install -g @railway/cli
# Login to Railway
railway login
# Initialize project
railway init
# Create staging environment
railway environment --create staging
# Create production environment
railway environment --create production
# List all environments
railway environment
Environment Switching
# Switch to staging
railway environment staging
# Switch to production
railway environment production
# Deploy to specific environment
railway up --environment staging
railway up --environment production
Critical Pattern: Environment Variables Per Environment
# Switch to staging
railway environment staging
# Set staging-specific variables
railway variables set NODE_ENV=staging
railway variables set DATABASE_URL=${{Postgres.DATABASE_URL}}
railway variables set API_BASE_URL=https://api-staging.example.com
railway variables set LOG_LEVEL=debug
railway variables set RATE_LIMIT_MAX=1000
# Switch to production
railway environment production
# Set production-specific variables
railway variables set NODE_ENV=production
railway variables set DATABASE_URL=${{Postgres.DATABASE_URL}}
railway variables set API_BASE_URL=https://api.example.com
railway variables set LOG_LEVEL=error
railway variables set RATE_LIMIT_MAX=100
Multi-Environment Railway Configuration
# railway.toml
[build]
builder = "NIXPACKS"
buildCommand = "npm run build"
[deploy]
startCommand = "npm start"
healthcheckPath = "/health"
healthcheckTimeout = 100
restartPolicyType = "ON_FAILURE"
restartPolicyMaxRetries = 10
# Staging-specific overrides
[environments.staging]
[environments.staging.deploy]
startCommand = "npm run start:staging"
# Production-specific overrides
[environments.production]
[environments.production.deploy]
startCommand = "npm run start:production"
numReplicas = 2
Per-Environment Databases
# Staging environment
railway environment staging
railway add --plugin postgresql
# Production environment
railway environment production
railway add --plugin postgresql
Database Connection Pattern
// config/database.js
const getDatabaseConfig = () => {
const env = process.env.RAILWAY_ENVIRONMENT || 'development';
return {
connectionString: process.env.DATABASE_URL,
ssl: env === 'production' ? { rejectUnauthorized: false } : false,
max: env === 'production' ? 20 : 10,
idleTimeoutMillis: 30000,
connectionTimeoutMillis: 2000,
};
};
module.exports = getDatabaseConfig();
Cache Layer Setup
# Add Redis to staging
railway environment staging
railway add --plugin redis
# Add Redis to production
railway environment production
railway add --plugin redis
Redis Configuration
// config/redis.js
const redis = require('redis');
const client = redis.createClient({
url: process.env.REDIS_URL,
socket: {
connectTimeout: 5000,
reconnectStrategy: (retries) => {
if (retries > 10) return new Error('Max retries reached');
return Math.min(retries * 100, 3000);
}
}
});
module.exports = client;
Setting Up Custom Domains
# Staging domain
railway environment staging
railway domain add staging.example.com
# Production domain
railway environment production
railway domain add example.com
railway domain add www.example.com
SSL Certificate Management
DNS Configuration
# For root domain (example.com)
Type: A
Name: @
Value: [Railway IP from dashboard]
# For www subdomain
Type: CNAME
Name: www
Value: [Railway domain from dashboard]
# For staging subdomain
Type: CNAME
Name: staging
Value: [Railway staging domain]
Railway Service Configuration
# apps/api/railway.toml
[build]
builder = "NIXPACKS"
buildCommand = "npm run build --workspace=api"
watchPaths = ["apps/api/**"]
[deploy]
startCommand = "npm run start --workspace=api"
# apps/web/railway.toml
[build]
builder = "NIXPACKS"
buildCommand = "npm run build --workspace=web"
watchPaths = ["apps/web/**"]
[deploy]
startCommand = "npm run start --workspace=web"
Multi-Service Deployment Strategy
# Deploy API service
cd apps/api
railway up --service api
# Deploy Web service
cd apps/web
railway up --service web
# Deploy Worker service
cd apps/worker
railway up --service worker
Internal Service Communication
// Use Railway private networking
const API_INTERNAL_URL = process.env.RAILWAY_PRIVATE_DOMAIN
? `http://${process.env.RAILWAY_PRIVATE_DOMAIN}:${process.env.PORT}`
: process.env.API_URL;
// Service-to-service communication
const response = await fetch(`${API_INTERNAL_URL}/internal/data`);
Enable Private Networking
# Private networking is automatically available
# Access services via: servicename.railway.internal
Private Network Usage
// config/services.js
const getServiceUrls = () => {
const isRailway = process.env.RAILWAY_ENVIRONMENT;
return {
apiUrl: isRailway
? 'http://api.railway.internal:3000'
: 'http://localhost:3000',
workerUrl: isRailway
? 'http://worker.railway.internal:4000'
: 'http://localhost:4000',
};
};
Creating Volumes
# Via CLI (dashboard preferred for volumes)
# Volumes persist data across deployments
# Mount point configuration in railway.toml
[deploy]
volumes = [
{ name = "uploads", mountPath = "/app/uploads" },
{ name = "cache", mountPath = "/app/cache" }
]
Volume Usage Patterns
// services/storage.js
const fs = require('fs').promises;
const path = require('path');
const UPLOAD_DIR = process.env.RAILWAY_VOLUME_UPLOADS_PATH || './uploads';
const saveFile = async (filename, data) => {
const filepath = path.join(UPLOAD_DIR, filename);
await fs.writeFile(filepath, data);
return filepath;
};
module.exports = { saveFile };
Automatic Deployments
# Configure branch-based deployments in Railway dashboard
# Staging: deploy from 'develop' branch
# Production: deploy from 'main' branch
Manual Deployment Control
# Disable auto-deploy and deploy manually
railway up
# Deploy specific commit
railway up --commit abc123
# Deploy from local directory
railway up --detach
Triggering Deployments
# Get webhook URL from Railway dashboard
curl -X POST https://railway.app/api/webhooks/deploy/[project-id]
Implementing Health Endpoints
// routes/health.js
const express = require('express');
const router = express.Router();
router.get('/health', async (req, res) => {
const checks = {
database: await checkDatabase(),
redis: await checkRedis(),
disk: await checkDiskSpace(),
};
const isHealthy = Object.values(checks).every(c => c.status === 'ok');
const statusCode = isHealthy ? 200 : 503;
res.status(statusCode).json({
status: isHealthy ? 'healthy' : 'unhealthy',
environment: process.env.RAILWAY_ENVIRONMENT,
checks,
timestamp: new Date().toISOString(),
});
});
module.exports = router;
Railway Health Check Config
[deploy]
healthcheckPath = "/health"
healthcheckTimeout = 100
restartPolicyType = "ON_FAILURE"
restartPolicyMaxRetries = 10
Structured Logging
// utils/logger.js
const winston = require('winston');
const logger = winston.createLogger({
level: process.env.LOG_LEVEL || 'info',
format: winston.format.json(),
defaultMeta: {
service: process.env.RAILWAY_SERVICE_NAME,
environment: process.env.RAILWAY_ENVIRONMENT,
},
transports: [
new winston.transports.Console({
format: winston.format.simple(),
}),
],
});
module.exports = logger;
CLI Log Access
# View recent logs
railway logs
# Follow logs in real-time
railway logs --follow
# Filter logs by service
railway logs --service api
# Filter by environment
railway environment production
railway logs --follow
Log Management Strategies
// middleware/logging.js
const logger = require('../utils/logger');
const requestLogger = (req, res, next) => {
const start = Date.now();
res.on('finish', () => {
const duration = Date.now() - start;
logger.info('HTTP Request', {
method: req.method,
path: req.path,
statusCode: res.statusCode,
duration,
userAgent: req.get('user-agent'),
ip: req.ip,
});
});
next();
};
module.exports = requestLogger;
Resource Optimization Checklist
Environment-Specific Scaling
# Staging: minimal resources
[environments.staging.deploy]
numReplicas = 1
# Production: scaled resources
[environments.production.deploy]
numReplicas = 2
Pre-Promotion Checklist
Promotion Strategy
# 1. Test in staging
railway environment staging
railway up
# Verify deployment
# 2. Run smoke tests
npm run test:smoke -- --env=staging
# 3. Promote to production
railway environment production
# 4. Update production environment variables if needed
railway variables set NEW_FEATURE_FLAG=true
# 5. Deploy to production
railway up
# 6. Monitor production logs
railway logs --follow
# 7. Verify production health
curl https://example.com/health
Database Migration Pattern
# 1. Run migrations in staging
railway environment staging
railway run npm run migrate
# 2. Verify data integrity
railway run npm run verify:data
# 3. Run migrations in production
railway environment production
railway run npm run migrate
# 4. Deploy application
railway up
Issue: Build Failures
# Check build logs
railway logs --build
# Common fixes:
# 1. Verify buildCommand in railway.toml
# 2. Check Node.js version compatibility
# 3. Verify dependencies in package.json
# 4. Clear build cache via dashboard
Issue: Environment Variable Not Found
# List all variables in current environment
railway variables
# Verify environment
railway environment
# Set missing variable
railway variables set VAR_NAME=value
Issue: Database Connection Failures
// Add connection retry logic
const { Pool } = require('pg');
const pool = new Pool({
connectionString: process.env.DATABASE_URL,
max: 20,
connectionTimeoutMillis: 5000,
idleTimeoutMillis: 30000,
ssl: { rejectUnauthorized: false }
});
pool.on('error', (err) => {
console.error('Unexpected database error', err);
});
Issue: Service Won't Start
# Check service logs
railway logs --service servicename
# Verify start command
railway run echo $PORT
# Test locally with same environment
railway run npm start
Issue: Domain Not Resolving
# Verify DNS propagation
dig example.com
nslookup example.com
# Check Railway domain status in dashboard
# Verify SSL certificate provisioned
# Allow 24-48 hours for DNS propagation
Slow Response Times
// Add performance monitoring
const perf = require('perf_hooks').performance;
app.use((req, res, next) => {
const start = perf.now();
res.on('finish', () => {
const duration = perf.now() - start;
if (duration > 1000) {
logger.warn('Slow request', {
path: req.path,
duration
});
}
});
next();
});
