import/no-internal-modules

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

Rule Details

This rule has two mutally exclusive options that are arrays of minimatch/glob patterns patterns:

allow that include paths and import statements that can be imported with reaching.
forbid that exclude 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

export { settings } from './app/index'; // Reaching to "./app/index" is not allowed
export * from './reducer/user'; // Reaching to "./reducer/user" 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';

export * from 'source-map-support/register';
export { settings } from '../app';
