Getting System Info with the os Module
When you build Node.js applications that need to adapt to different environments or monitor system resources, the os module is a powerful tool. You can use it to detect the host operating system, check available memory before performing resource-intensive tasks, or gather detailed CPU info for logging and diagnostics.
For example, a server application might log the platform and memory stats at startup to help with troubleshooting, or a monitoring tool could periodically check CPU load and free memory to alert you before the system runs low on resources.
The os module gives you a simple way to access this data directly from your code, making your applications smarter and more robust in production.
