What did you do? Please include the actual source code causing the issue.

I added

"quotes": ["error", "backtick"]

to .eslintrc and

eslint src --fix to the scripts in package.json

after reading this

What did you expect to happen?

' to be replaced by backtips ONLY where applicable (as like: not in 'use strict'). OR: Other rules not to complain about where --fix sets backtips.

What actually happened? Please include the actual, raw output from ESLint.

this code:

'use strict'

module.exports = (string) => {
  if (string && typeof string === `string`) {
    // does something

produced this error:

  10:35   error  Typeof comparisons should be to string literals  valid-typeof

It seems like the bug here is that valid-typeof doesn’t allow comparisons to template literals.

typeof foo === `string`

should not cause an error to be reported.
