How to check if an arbitrary PID is running using Node.js?

Question

Is there some way to check if an arbitrary PID is running or alive on the system, using Node.js? Assume that the Node.js script has the appropriate permissions to read

Answer 1

I needed to check for running pid's in a project as well. I took this answer of using kill -0 and wrapped it up in a module called is-running https://npmjs.org/package/is-running

npm install is-running
