Hi Chris,
Thanks for trying to help !
This is the URL of my tutorial :
MDN Web Docs
Setting up a Node development environment
You now have a Node development environment up and running on
your computer that can be used for creating Express web
applications. You've also seen how NPM can be used to import
Express into an application, and also how you can create
applications...
I was following the section “Using NPM”, at the “Running
tasks” step.
I successfully ran through all the steps above when I encountered
the problems I described.

Right.
So the good news is that you don’t need to follow this bit of
the tutorial to use the rest of it. I’d probably advise ignoring
eslint and npm scripts for now, as they are fiddly and hard to
configure.
If you want to continue trying to get this working, here are
some tips:
You need to add in the npm script to the package.json file,
something like this:
{
"name": "myapp",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"lint": "eslint index.js"
},
"author": "",
"license": "ISC",
"dependencies": {
"express": "^4.17.1"
},
"devDependencies": {
"eslint": "^6.0.1"
}
}
To create an eslint config, the easiest way is to use npx
eslint --init - npx directly runs commands that
are available inside node modules, rather than you having to go
through the nightmare of figuring out all the path issues and
stuff
You can then run eslint on your index file using npx
eslint index.js. This works fine
To run the actual npm script we added to the package.json file,
you should be able to do npm run lint. This gives the
expected result, but it also throws an error right afterwards. And
I’m not sure why.
I’ve run out of time to look into this any more, but I hope
this helps a bit.
