+⚠️ This rule _warns_ in the 🚸 `warnings` config.
+
+<!-- end auto-generated rule header -->
+
+Prohibit importing a default export by another name.
+
+## Rule Details
+
+Given:
+
+```js
+// api/get-users.js
+export default async function getUsers() {}
+```
+
+...this would be valid:
+
+```js
+import getUsers from './api/get-users.js'
+```
+
+...and the following would be reported:
+
+```js
+// Caution: `get-users.js` has a default export `getUsers`.
+// This imports `getUsers` as `findUsers`.
+// Check if you meant to write `import getUsers from './api/get-users'` instead.
+import findUsers from './get-users'
+```
