Question: How to launch a cached njs package

Hi, I have a quick question for the esteemed panel
I have a set of nodejs packages which I would like to ensure are launched cached via a json ecosystem file, like one can launch from the commandline with 'npm run start:cached' - I am not sure if this is already happening or if other parameters needs to be set in the file. My apps entries currently look like this:

            {
                    "name": "PackageName",
                    "script": "./dist/app.js",
                    "instances": 1,
                    "cwd": "/home/pi/appfolder"
            },

Would be stellar if you can offer any guidance

The issue mentions an ecosystem JSON file and the npm run start:cached command, but names no repository file, test, or concrete change. First clarify whether the desired outcome is documentation or a configuration behavior, then define how a successful cached launch should be verified.
