How to run a Debian Node.js application stably

This article describes how to run Node.js applications stably on Debian systems and provides a series of best practices.

1. Install Node.js and npm

It is recommended to use the NodeSource repository to get the latest stable version. First add the repository:

 curl -fsSL https://deb.nodesource.com/setup_14.x | sudo -E bash -

Then install Node.js and npm:

 sudo apt-get install nodejs

After the installation is complete, verify using the following command:

 node -v
npm -v

2. Security configuration

• Avoid root permissions running: Never use root users to run Node.js applications, as this will greatly increase security risks.
• Regularly update npm packages: Use npm audit or similar tools (such as snyk) to regularly check and update npm packages to fix potential security vulnerabilities.
• Secure HTTP headers: Configure secure HTTP headers, such as Content-Security-Policy and X-Content-Type-Options , to enhance application security.
• Implement rate limiting: Rate limiting requests to effectively defend against potential DDoS attacks.
• Force HTTPS: Always use HTTPS to encrypt data transmission to protect user data security.

3. Monitoring and maintenance

• Performance monitoring: Use monitoring tools such as Prometheus and Grafana to track application performance and resource consumption in real time.
• Regular updates: Regular updates to Node.js version and application dependencies to ensure application stability and security.

4. Select the LTS version

The Long-term Support (LTS) version of Node.js is preferred, which has longer maintenance cycles and security updates, making it more suitable for production environments.

Following the above steps and suggestions can significantly improve the stability and security of Node.js applications on Debian systems.
