package.json file is modified automatically when you add some dependencies.

In the very beginning you need to initialize your app with:

npm init

then install what you need use: npm i mysql

https://www.npmjs.com/package/mysql

and so on for other dependencies

You can run npm init to run a questionnaire to generate a package.json or run npm init -y to generate a default package.json.

See this documentation.

Here is how a default package.json looks like:

{
    "name": "my_package",
    "description": "",
    "version": "1.0.0",
    "main": "index.js",
    "scripts": {
      "test": "echo \"Error: no test specified\" && exit 1"
    },
    "repository": {
      "type": "git",
      "url": "https://github.com/ashleygwilliams/my_package.git"
    },
    "keywords": [],
    "author": "",
    "license": "ISC",
    "bugs": {
      "url": "https://github.com/ashleygwilliams/my_package/issues"
    },
    "homepage": "https://github.com/ashleygwilliams/my_package"
  }

Then when you run npm install some_package it will be added to the denpendencies.
