Node.js applications are increasingly popular for their scalability and performance. This guide walks you through deploying a Node.js application on AWS Lightsail with production-ready configurations.

Environment Setup

Blueprint Selection and Initial Configuration

1. Choose the Node.js blueprint:
   • Log in to AWS Lightsail console
   • Click “Create instance”
   • Select “Node.js” under the Apps + OS category
   • Verify the Node.js version is current (v18 LTS or newer as of May 2025)
2. Select appropriate instance plan:
   • Small ($5/mo): Development and testing environments
   • Medium ($10/mo): Small production applications with moderate traffic
   • Large ($20/mo): Production applications with higher traffic volume
   • Rule of thumb: Choose an instance with at least 2GB RAM for production Node.js apps
3. Configure instance location:
   • Select a region close to your target audience
   • Choose an availability zone (or use the default)
4. Set instance identifiers:
   • Use descriptive instance names (e.g., “nodejs-api-production”)
   • Add tags for organization (e.g., “service:api”, “environment:production”)

Example: Creating a Node.js instance with AWS CLI

aws lightsail create-instances \
  --region us-west-2 \
  --instance-names nodejs-api-production \
  --availability-zone us-west-2a \
  --blueprint-id nodejs \
  --bundle-id medium_3_0 \
  --tags key=service,value=api key=environment,value=production

Logging into the Instance

1. Download the ssh key

aws lightsail download-default-key-pair --output text --query privateKeyBase64 --region us-west-2 >  lightsail-key.pem

2. SSH to the instance

ssh -i path/to/key bitnami@IP_ADDRESS

The IP address can be retrieved from the AWS Console

Instance Preparation

After your instance is created, perform these important preparation steps:

1. Update system packages:
   sudo apt update && sudo apt upgrade -y
2. Install additional development tools:
   sudo apt install -y build-essential git curl
3. Update Node.js if needed:
   # Check current version
node -v
# If needed, install newer version using NVM
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash
source ~/.bashrc
nvm install --lts
nvm use --lts
nvm alias default 'lts/*'
4. Install global Node.js utilities:
   npm install -g npm-check-updates
5. Configure firewall for Node.js:
   # Using AWS CLI
aws lightsail open-instance-public-ports \
--port-info fromPort=3000,toPort=3000,protocol=TCP \
--instance-name nodejs-api-production

Application Deployment

Code Deployment Options

Choose the deployment method that best fits your workflow:

1. Git-based deployment (recommended):
   # Connect to your instance
ssh -i lightsail_key.pem bitnami@your-instance-ip
# Create app directory
sudo mkdir -p /opt/bitnami/projects
sudo chown -R bitnami:bitnami /opt/bitnami/projects
cd /opt/bitnami/projects
# Clone your repository
git clone https://github.com/yourusername/your-nodejs-app.git .
cd [APP_NAME]
# Install dependencies
npm ci --production
2. Direct file transfer:
   # From your local machine
# Compress your application (excluding node_modules)
tar -czf app.tar.gz --exclude="node_modules" --exclude=".git" .
# Upload to server
scp -i lightsail_key.pem app.tar.gz bitnami@your-instance-ip:/tmp/
# On server: Extract and install
ssh -i lightsail_key.pem bitnami@your-instance-ip
sudo mkdir -p /opt/bitnami/projects
sudo chown -R bitnami:bitnami /opt/bitnami/projects
tar -xzf /tmp/app.tar.gz -C /opt/bitnami/projects
cd /opt/bitnami/projects/[APP_NAME]
npm ci --production

Process Management with systemd

Systemd is the recommended way to manage your Node.js application as a service, ensuring it runs continuously and restarts after crashes or system reboots:

1. Create a systemd service file /etc/systemd/system/nodejs-api.service:
   Add the following basic configuration:
   [Unit]
Description=Node.js API Application
After=network.target
[Service]
Type=simple
User=bitnami
WorkingDirectory=/opt/bitnami/projects/[APP_NAME]
ExecStart=/usr/bin/node /opt/bitnami/projects/[APP_NAME]/app.js
Restart=on-failure
RestartSec=10
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=nodejs-api
[Install]
WantedBy=multi-user.target
2. Create log directory and configure system logging:
   # Create log directory
sudo mkdir -p /opt/bitnami/logs
sudo chown -R bitnami:bitnami /opt/bitnami/logs
   
   Configure rsyslog to store application logs. Add the following content /etc/rsyslog.d/nodejs-api.conf:
   if $programname == 'nodejs-api' then /opt/bitnami/logs/nodejs-app.log & stop
   
   Restart rsyslog:
   sudo systemctl restart rsyslog

Environment Configuration

Configure environment variables for your application before starting the service:

1. Add environment variables directly to the systemd service file (recommended for production) /etc/systemd/system/nodejs-api.service:
   
   Add environment variables under the [Service] section:
   [Service]
# ...existing configuration...
Environment=NODE_ENV=production
Environment=PORT=3000
Environment=DB_HOST=your-db-endpoint.us-west-2.compute.amazonaws.com
Environment=DB_USER=dbuser
Environment=DB_PASS=dbpassword
Environment=DB_NAME=appdb
Environment=REDIS_URL=redis://localhost:6379
Environment=API_KEY=your-api-key
2. Alternative: Use an environment file with systemd:
   
   Create environment file cd /opt/bitnami/projects/.env.production
   Add your variables:
   NODE_ENV=production
PORT=3000
DB_HOST=your-db-endpoint.us-west-2.compute.amazonaws.com
DB_USER=dbuser
DB_PASS=dbpassword
DB_NAME=appdb
REDIS_URL=redis://localhost:6379
API_KEY=your-api-key
   
   Secure the file:
   sudo chmod 600 .env.production
sudo chown bitnami:bitnami .env.production
   
   Then reference it in your systemd service file:
   [Service]
# ...existing configuration...
EnvironmentFile=/opt/bitnami/projects/[APP_NAME]/.env.production
3. For development only: Using .env with dotenv package:
   // Only for development - NOT recommended for production
if (process.env.NODE_ENV !== 'production') {
require('dotenv').config();
}

Starting and Managing the Application

After configuring both the service file and environment variables:

1. Enable and start the application service:
   sudo systemctl daemon-reload
sudo systemctl enable nodejs-api
sudo systemctl start nodejs-api
2. Monitor application status and logs:
   # Check service status
sudo systemctl status nodejs-api
# View application logs
sudo journalctl -u nodejs-api
# Follow logs in real-time
sudo journalctl -u nodejs-api -f
# View logs with timestamps
sudo journalctl -u nodejs-api --since today
# View recent logs from application log file
tail -f /opt/bitnami/logs/nodejs-app.log
3. Service management commands:
   # Stop the application
sudo systemctl stop nodejs-api
# Restart the application
sudo systemctl restart nodejs-api
# Reload systemd after changing service file
sudo systemctl daemon-reload

Production Configuration

Apache as Reverse Proxy

The Bitnami Node.js blueprint comes with Apache pre-installed which can be used as a reverse proxy. If you’d like to use Nginx please follow our Nginx reverse proxy guide.

1. Create an Apache virtual host configuration:
   # Copy the sample vhost configuration
sudo cp /opt/bitnami/apache/conf/vhosts/sample-vhost.conf.disabled /opt/bitnami/apache/conf/vhosts/nodejs-app.conf
2. Update the virtual host configuration:
   <VirtualHost 127.0.0.1:80 _default_:80>
ServerName yourdomain.com
ServerAlias www.yourdomain.com
DocumentRoot /opt/bitnami/projects/[APP_NAME]
<Directory "/opt/bitnami/projects/[APP_NAME]">
Options -Indexes +FollowSymLinks -MultiViews AllowOverride All
Require all granted
</Directory>
# Proxy configuration for Node.js application
ProxyPass / http://localhost:3000/
ProxyPassReverse / http://localhost:3000/
# Add HTTP security headers
Header always set X-Content-Type-Options "nosniff"
Header always set X-Frame-Options "SAMEORIGIN"
Header always set X-XSS-Protection "1; mode=block"
# Enable compression
AddOutputFilterByType DEFLATE text/plain text/html text/xml text/css application/xml application/xhtml+xml application/rss+xml application/javascript application/x-javascript application/json
</VirtualHost>
3. Enable Apache modules needed for proxy:
   sudo /opt/bitnami/apache/bin/a2enmod proxy
sudo /opt/bitnami/apache/bin/a2enmod proxy_http
sudo /opt/bitnami/apache/bin/a2enmod headers
sudo /opt/bitnami/apache/bin/a2enmod deflate
4. Restart Apache to apply changes:
   sudo /opt/bitnami/ctlscript.sh restart apache

Performance Optimization

Application Performance Tuning

1. Configure Node.js memory limits:
   # Update systemd service file with memory limits
sudo nano /etc/systemd/system/nodejs-api.service
# Add under [Service] section:
# MemoryLimit=1G
# Reload systemd and restart service
sudo systemctl daemon-reload
sudo systemctl restart nodejs-api
2. Enable response compression:
   // In your Node.js app
const compression = require('compression');
app.use(compression());
3. Implement caching strategies:
   • Response caching
   • Database query caching
   • Static asset caching
4. Optimize database queries:
   • Use indexing
   • Implement connection pooling
   • Consider Redis for session storage

Static Content Delivery

For applications with static content:

1. Configure Apache caching for static files /opt/bitnami/apache/conf/vhosts/nodejs-app.conf:
   
   Add inside the VirtualHost block:
   # Cache static content
<FilesMatch "\.(jpg|jpeg|png|gif|ico|css|js)$">
Header set Cache-Control "max-age=2592000, public"
</FilesMatch>
2. Consider CloudFront integration:
   • Create a CloudFront distribution
   • Configure your origin as your Lightsail instance
   • Update DNS to use CloudFront endpoint

Monitoring and Logging

Application Monitoring

1. Configure application logging:
   // In your Node.js app
const winston = require('winston');
const logger = winston.createLogger({
level: 'info',
format: winston.format.json(),
defaultMeta: { service: 'nodejs-api' },
transports: [
new winston.transports.File({ filename: 'error.log', level: 'error' }),
new winston.transports.File({ filename: 'combined.log' })
]
});
2. Set up log rotation /etc/logrotate.d/nodejs:
   /opt/bitnami/logs/*.log {
daily
missingok
rotate 14
compress
delaycompress
notifempty
create 0640 bitnami bitnami
sharedscripts
postrotate
systemctl restart nodejs-api > /dev/null 2>&1
endscript
}

Scaling Your Node.js Application

As your application grows, consider these scaling strategies:

1. Vertical scaling:
   • Upgrade to larger Lightsail instance
   • Optimize application for better resource utilization
2. Horizontal scaling:
   • Deploy multiple instances behind a load balancer
   • Ensure application is stateless
   • Use Redis or other external store for sessions
3. Service decomposition:
   • Break monolithic app into microservices
   • Deploy separate services on different instances
   • Implement API gateway pattern

Example: Multi-instance Node.js architecture

[Lightsail Load Balancer]
         /      \
[Node.js Instance 1] [Node.js Instance 2]
         \      /
    [Redis for Sessions]
           |
    [Lightsail Database]
