The os module in Node.js is a core module that provides a set of functions and methods for interacting with the underlying operating system. It allows you to retrieve information about the operating system, system resources, and provides a platform-independent way to perform certain system-related tasks. The primary purpose of the
os module is to provide information and utilities related to the operating system. Here are some of the key purposes and functionalities of the
os module:
Platform Information:
The os.platform() method returns a string indicating the platform on which Node.js is running, such as "darwin" for macOS, "win32" for Windows, or "linux" for Linux.
Operating System Version:
The os.version() method returns the version of the operating system.
Hostname:
The os.hostname() method returns the hostname of the operating system.
User Information:
The os.userInfo() method provides information about the currently logged-in user, including the username, user ID, and home directory.
System Uptime:
The os.uptime() method returns the system uptime in seconds since the computer was last started.
Memory Information:
Functions like os.totalmem() and os.freemem() provide information about the total and free system memory in bytes.
CPU Information:
The os.cpus() method returns an array of objects, each representing a CPU core, with information about the core's speed, model, and more.
Network Interfaces:
The os.networkInterfaces() method retrieves information about the network interfaces on the system, including their IP addresses and related data.
Load Averages:
The os.loadavg() method returns an array of three numbers representing the system's 1-minute, 5-minute, and 15-minute load averages.
File Paths and Delimiters:
The os.homedir(), os.tmpdir(), and 
os.EOL properties provide file system-related information, such as the user's home directory, the system's temporary directory, and the line ending used by the operating system.
