Returning a value to shell script from a node.js file

Question

I am calling a NodeJS file like this in a shell script:

$ node process.js
$ let "errors |= $?"

I want to see if the process.js file returned any errors. How do I return a value inside process.js file so that I can capture it in my shell script.

Answer 1

You can set the exitCode (and let the node process die naturally):

process.exitCode = 1 

Or you can force-kill it:

process.exit(1)

in both cases it will return 1 as the exit code.
