Solved it with adding this to my .eslintrc:
"import/no-extraneous-dependencies": ["error", {"devDependencies": true}]
[no-extraneous-dependencies] Add exceptions? #422
Based on this user’s reply:
you could set the option devDependencies: true in an .eslintrc in your
test folder:rules: import/no-extraneous-dependencies: [error, { devDependencies:
true }] Then you’ll get reports of any packages referenced that are
not included dependencies or devDependencies. Then you get the
goodness of the rule, with no noise from the disable comments.I think that might work for you? This is how I would use the rule, in
your case, since you have your test code separated into a test
directory.
Also this post was helpful to confirm I wasn’t insane to not want some of these in my dependencies list: Sharable ESLint Config
