How to deploy Node.js app with PM2 in production — boobo94

To deploy Node.js app with PM2 it’s very simple and nowadays is very important to use the right tool which facilitate your time. Time is the most valuable resource that a human being can own, so try to avoid those tools which are time-consuming.

I would like to present below a simple solution found by me to deploy Node.js app with PM2. I needed a fast solution and with less configuration as possible. I tried as well Forever JS, you can find the NPM page here or Github repository. But I prefer the documentation and explanation of [PM2](https://pm2.keymetrics.io/).

Firstly you need to create a pm2.json file and put it preferably in the root of your project:

{
    "apps": [
        {
            "name": "web",
            "exec_mode": "cluster",
            "instances": "max",
            "script": "./lib/server.ts",
            "interpreter": "ts-node",
            "env": {
                "ENV": "prod",
                "PORT": 3000,
                "DB_USERNAME": "boobo94_username",
                "DB_PASSWORD": "123",
                "DB_NAME": "some_db_name",
                "DB_HOST": "127.0.0.1",
                "DB_DIALECT": "postgres",
                "DB_PORT": 5432,
                "SECRET_KEY": "boobo94_is_my_secret_key",
            }
        }
    ]
}
