+# no-reaching-inside
+
+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 patterns to identify directories whose children can be imported explicitly.
+
+### 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-reaching-inside": [ "error", {
+      "allow": [ "**/actions", "source-map-support/*" ]
+    } ]
+  }
+}
+```
+
+The following patterns are considered problems:
+
+```js
+/**
+ *  in my-project/entry.jz
+ */
+
+import { settings } from './app/index'; // Reaching into "./app" is not allowed
+import userReducer from './reducer/user'; // Reaching into "./reducer" is not allowed
+import configureStore from './redux/configureStore'; // Reaching into "./redux" is not allowed
+```
+
+The following patterns are NOT considered problems:
+
+```js
+/**
+ *  in my-project/entry.jz
+ */
+
+import 'source-map-support/register';
+import { settings } from '../app';
+import getUser from '../actions/getUser';
+```
