When running default npm init - can we not name it app.js anymore? I am getting error for not finding index.js.

Looks like npm init now has index.js as the default for the main js file

Tom Settle When you first run npm init it will take you through the setup of the npm package. Many of these are options that you have likely sort of just hit "Enter" and skipped through up until now. One of them looks like this:

entry point: (index.js)

If you do not enter a value here, it will default to index.js.

You will have a package.json file that may look similar to this:

{
  "name": "html",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "dependencies": {
    "normalize": "^0.3.1"
  },
  "devDependencies": {},
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC"
}

You can edit the "index.js" directly in that file and have it point to the main.js if you wish :smiley:

Hope this helps! :sparkles:

you get error if only the script your running is different than the package.json. however if you have nodemon installed as your dev setting then you change your main to app.js or what ever.
