How do I do an eol-last check with ESLint?

Question

I'm writing a node project with syntax checking through ESLint. I want to meet POSIX standard and have a newline at the end of every file, so I set the eol-last test to 2 in my .eslintrc . However, this rule seems to be totally ignored while others work just fine.

I tried this .eslintrc :

{
  "rules": {
    "eol-last": 2,
    "no-console": 2
  }
}

and tested this file:

 console.log('Test');

In response, I get:

1:1  error  Unexpected console statement  no-console

✖ 1 problem (1 error, 0 warnings)

It makes no sense to me. I've tried everything and the rule seems to be useless. Thank you.

If you use unix style ( lf ) then it will work as you have it configured above. You can try it on online demo .

If you use windows styles ( crlf ), then you need to configure the rule like this:

{
    "eol-last": [2, "windows"]
}
