|
When there is only a single export from a module, prefer using default export over named export.
|
||
|
|
|
||
|
|
## Rule Details

||
|

The following patterns are considered warnings:

```javascript
|
||
|
|
// bad.js
|
||
|
|
|
||
|
|
// There is only a single module export and it's a named export.
|
||
|
|
export const foo = 'foo';
|
||
|
|
|
||
|
