Deployment Overview of Node.js on Server¶

Prerequisites and Basic Requirements¶

To ensure a successful deployment, the server must meet the following requirements:

Operating System: Ubuntu or Debian-based Linux distribution.
Privileges: Root or sudo access is required to install system packages and manage repositories.
Network Access: The server must have outbound internet access to reach NodeSource repositories and APT package mirrors.
System State: cloud-init must have completed its initial setup before the installation process begins.

Application Installation Process¶

The application environment is set up using a system-level installation method targeting the OS package manager. The following steps are performed:

Prerequisite Package Installation: The system installs curl and npm via the apt package manager to facilitate repository management.
Repository Configuration: The NodeSource APT repository is added to the system to ensure access to the latest stable Node.js versions.
Node.js Installation: The nodejs package is installed from the newly configured NodeSource repository.
Verification: The installation is verified by executing node -v to confirm the presence of the runtime in the system path.

Access Rights and Security¶

Package Management Security: During the installation, the process waits for any existing dpkg or apt locks to be released to prevent database corruption.
System Updates: The package lists are updated (apt update) prior to installing dependencies to ensure all software is sourced from secure, up-to-date repositories.

Application Update Instructions¶

To update the Node.js runtime and associated system dependencies, use the standard package manager commands:

sudo apt update && sudo apt upgrade nodejs

Available Ports for Connection¶

The application utilizes the Node.js runtime; specific application ports are determined by the application configuration once the service is initialized. Standard web traffic typically flows through port 80 or 443.
