NodeJS passing command line arguments to forever

Question

Im trying to pass command line arguments to forever, that I want to parse in my app.

Currently I'm starting my app like this:

forever start -c "node --max-old-space-size=8192 --nouse-idle-notification" /home/ubuntu/node/server.js

I want to be able to read some arguments in my server.js.

My code for reading:

var arguments = process.argv.slice(2);
console.log(arguments[0]);

if(!arguments[0]) {
    console.log("Error: Missing port.");
    process.exit(1);
}

But how to I tell forever to pass arguments that can be read inside server.js?

Answer 1

According to the forever docs, you should use this format where you append your script arguments to the very end:

forever [action] [options] SCRIPT [script-options]

So for your example, you should be able to do this (omitting the -c options to make this a little more readable):

forever start server.js 9000 anotherarg evenanother

You can add the -c and the full path to server.js back into your real call, based upon your situation.
