'Why does this error happen? "npm run dev missing script error"

I've been trying to follow the following tutorial: https://github.com/digitsensitive/phaser3-typescript/blob/master/README.md

These are the steps that I had to follow

Prerequisites Download and install npm with Node.js @ https://nodejs.org/en Installing Select a folder, navigate to it, and clone this repository with this command-line:

git clone https://github.com/digitsensitive/phaser3-typescript.git

Install the dependencies with this command-line:

npm install

If you use yarn just replace npm with yarn

Building and Running Perform a quick build (bundle.js) and start server: npm run dev

I've never used node.js and npm before so I'm stumbling across some newbie mistakes. One error I get is that when I try to run npm run dev, Git bash returns the following error code:

npm ERR! missing script: dev

I don't know what I should be adding to my package.json file to make this work. Could anyone help me with this please?

I made a package.json using init, but the tutorial doesn't state that I have to do this. I don't know why I should manually make a package.json file in the first place.

Just add div in scripts object in your package.json file as you see

"scripts": {
    "start": "node ./bin/www",
      "dev": "nodemon ./bin/www"
    },

that's if you use nodemon package
