Question 1

How do I use ps-list to only show processes from the current user?

Accepted Answer

Pass the option {all: false} when calling psList(). On macOS and Linux, this filters to current user processes, but on Windows, it has no effect and all users' processes are always included, as noted in the README.

Question 2

ps-list vs systeminformation library for process monitoring in Node.js?

Accepted Answer

ps-list is focused solely on process listing with a minimal API, ideal for lightweight process inspection. systeminformation offers broader system metrics (CPU, memory, disk) but is heavier; choose ps-list for simplicity or systeminformation for comprehensive data.

Question 3

Why does ps-list not return CPU usage on Windows?

Accepted Answer

The README states that on Windows, properties like cpu, memory, and cmd are unavailable due to platform constraints. ps-list uses fastlist, which may not expose these details, so you'll need alternative tools for Windows-specific metrics.

Question 4

Can ps-list be used in Electron apps?

Accepted Answer

Yes, since it's a Node.js library, it should work in Electron. However, ensure the fastlist binary is bundled correctly for Windows deployments, and be mindful of platform-specific data limitations in cross-platform apps.

Question 5

How to handle the fastlist binary in production with ps-list?

Accepted Answer

The binary is typically installed automatically, but for production, verify it's included in your deployment package or PATH. Refer to the fastlist project documentation for specific installation steps and security considerations.

Question 6

What are the performance implications of calling ps-list repeatedly?

Accepted Answer

ps-list is asynchronous and involves system calls or binary execution, so frequent polling (e.g., in loops) can add overhead. For real-time monitoring, cache results or throttle calls to avoid performance degradation.
