eslint should be listed in the project's dependencies, not devDependencies

Question

Either I don\'t understand dependencies vs. devDependencies in node 100% yet or eslint is just wrong here (not capable of analyzing this correctly):

Answer 1

If you want to allow imports of devDependencies in test files only you can use an array of globs, as the documentation of no-extraneous-dependencies states:

When using an array of globs, the setting will be set to true (no errors reported) if the name of the file being linted matches a single glob in the array, and false otherwise.

The following setting will disable the lint for test files only.

"import/no-extraneous-dependencies": ["error", {"devDependencies": ["**/*.test.ts", "**/*.test.tsx"]}]

That way imports from devDependencies are still reported as errors.
