import/no-internal-modules

Use this rule to prevent importing the submodules of other modules.

Rule Details

This rule has one option, allow which is an array of minimatch/glob patterns patterns that whitelist paths and import statements that can be imported with reaching.

Examples

Given the following folder structure:

my-project
├── actions
│   └── getUser.js
│   └── updateUser.js
├── reducer
│   └── index.js
│   └── user.js
├── redux
│   └── index.js
│   └── configureStore.js
└── app
│   └── index.js
│   └── settings.js
└── entry.js

And the .eslintrc file:

{
  ...
  "rules": {
    "import/no-internal-modules": [ "error", {
      "allow": [ "**/actions/*", "source-map-support/*" ]
    } ]
  }
}

The following patterns are considered problems:

/**
 *  in my-project/entry.js
 */

import { settings } from './app/index'; // Reaching to "./app/index" is not allowed
import userReducer from './reducer/user'; // Reaching to "./reducer/user" is not allowed
import configureStore from './redux/configureStore'; // Reaching to "./redux/configureStore" is not allowed

The following patterns are NOT considered problems:

/**
 *  in my-project/entry.js
 */

import 'source-map-support/register';
import { settings } from '../app';
import getUser from '../actions/getUser';
