Get data about process resources without executing terminal commands

That's right. Unlike existing tools, this module directly retrieves data about processes without needing to open a new shell and wait for a terminal command's response.
Supports Windows, Linux, and MacOS
NodeJS module written in C++
Prebuilt binaries for linux-x64, win32-x64, darwin-x64, and darwin-arm64 (Darwin is the MacOS kernel)

Features

cpuUserTime(pid): Get user-mode CPU usage for a process in milliseconds.
cpuKernelTime(pid): Get kernel/system-mode CPU usage for a process in milliseconds.
cpuTime(pid): Get total CPU usage for a process in milliseconds (equivalent to cpuUserTime(pid) + cpuKernelTime(pid)).
memInfo(pid): Get current memory usage for a process in bytes.
memRSS(pid): Get current memory resident/working set size for a process in bytes.
fileRead(pid): Get total file read size for a process in bytes.
fileWrite(pid): Get total file write size for a process in bytes.

Installation

npm install node-ps-data

Known Issues and Future Plans

Build more binaries for other platforms and architectures.
More library functions: - CPU/Memory subcategories (e.g. child process time, pages info, etc.) - Network usage - GPU memory and usage - More!
