Either I don't understand dependencies vs. devDependencies in node 100% yet or eslint is just wrong here (not capable of analyzing this correctly):
3:1 error 'chai' should be listed in the project's dependencies, not devDependencies import/no-extraneous-dependencies
4:1 error 'chai-enzyme' should be listed in the project's dependencies, not devDependencies import/no-extraneous-dependencies
5:1 error 'enzyme' should be listed in the project's dependencies, not devDependencies import/no-extraneous-dependencies
7:1 error 'sinon' should be listed in the project's dependencies, not devDependencies import/no-extraneous-dependencies
9:1 error 'redux-mock-store' should be listed in the project's dependencies, not devDependencies import/no-extraneous-dependencies
These are test dependencies, so why is it saying that they should be listed in dependencies?
Additional note: We're using Travis as our CI so I don't know if it makes a difference for that at all either.
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
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.
I was able to solve it by adding the missing packages (in my case, Typescript and Storybook) to my plugins directory in .eslintrc.
I give the specifics in this post: ESLint error: '@storybook/react' should be listed in the project's dependencies, not devDependencies
