How to set up PM2?

Question

JavaScript

I started to deal with Node.js and got stuck with pm2 I run
the application on express.js like this pm2 start processes.json
The processes.json file itself

{
    "apps": [
        {
            "name": "Application",
            "script": "server.js",
            "port": "3000",
            "host": "127.0.0.1",
            "cwd": "./",
            "exec_interpreter" : "node",
            "watch": "true"
        }
    ]
}

I'm trying to open 127.0.0.1:3000
In Server.js, port 3000 is listening. What am I doing wrong?

Answer 1

The problem was in the last lines of the server. Thanks for the help.

// If someone ran: "node server.js" then automatically start the server
if (path.basename(process.argv[1], '.js') == path.basename(__filename, '.js')) {
    module.exports.start()
}
