# import/prefer-default-export
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';
```
The following patterns are not warnings:
```javascript
// good1.js
// There is a default export.
export const foo = 'foo';
const bar = 'bar';
export default bar;
```
```javascript
// good2.js
// There is more than one named export in the module.
export const foo = 'foo';
export const bar = 'bar';
```
```javascript
// good3.js
// There is more than one named export in the module
const foo = 'foo';
const bar = 'bar';
export { foo, bar }
```
```javascript
// good4.js
// There is a default export.
const foo = 'foo';
export { foo as default }
```
```javascript
// export-star.js
// Any batch export will disable this rule. The remote module is not inspected.
export * from './other-module'
```
