Question 1

How do I use human-signals to check if a signal is supported on my OS?

Accepted Answer

Import the library and access the signal object via signalsByName or signalsByNumber; the 'supported' property indicates if Node.js can handle it on your current OS, as shown in the README example with SIGINT.

Question 2

Human-signals vs os.constants.signals: what's the difference?

Accepted Answer

Human-signals adds human-readable descriptions, OS support detection, and action details, while os.constants.signals only provides raw constants. Use human-signals for better developer insight and cross-platform compatibility.

Question 3

Does human-signals include all signals for Windows?

Accepted Answer

It includes known signals across standards, but OS support varies; check the 'supported' property for Windows-specific signals, as the library maps cross-platform signals with details on compatibility.

Question 4

How to prevent a signal's default action using human-signals?

Accepted Answer

Human-signals doesn't handle signals; it provides metadata. Look at the 'forced' property—if false, you can prevent the default action by adding a signal handler in Node.js, but implementation is separate.

Question 5

What signals are covered in human-signals?

Accepted Answer

It covers known process signals from standards like ANSI, POSIX, BSD, and System V, with details on name, number, description, and more; refer to the library's source or documentation for the full list.

Question 6

Can I use human-signals in a TypeScript project?

Accepted Answer

Yes, it includes TypeScript definitions, but you must configure TypeScript to output ES modules, as specified in the README, due to its ESM-only nature.
