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.

Thanks again for looking at my problem.
I understood that it eslint is not needed to resume the tutorial
and I did what showed with your package.json.
I didn’t know about npx as I’m supposed to learn the
essentials and having the minimal working steps to reach some
knowledge !
What troubles me the most is that eslint on the the index.js
file ends up saying that require() is not defined !
Having followed other node.js and javascript tutorial, I would
have use “import”/“export” to include other .js file in
ES6. But I’ve noticed that node would not recognize that syntax
and I should use require().
Now, the eslint package does not recognize require, it is quite
shocking !
It is already confusing elsewhere, I did not expect more confusing
here at MDN !
Thanks again Chris, I’m still following the tutorial.
