# import/no-named-as-default
|
||
|
|
||
|
Reports use of an exported name as the locally imported name of a default export.
|
||
|
|
||
|
Rationale: using an exported name as the name of the default export is likely...
|
||
|
|
||
|
- *misleading*: others familiar with `foo.js` probably expect the name to be `foo`
|
||
|
- *a mistake*: only needed to import `bar` and forgot the brackets (the case that is prompting this)
|
||
|
|
||
|
## Rule Details
|
||
|
|
||
|
Given:
|
||
|
```js
|
||
|
// foo.js
|
||
|
export default 'foo';
|
||
|
export const bar = 'baz';
|
||
|
```
|
||
|
|
||
|
...this would be valid:
|
||
|
```js
|
||
|
import foo from './foo.js';
|
||
|
```
|
||
|
|
||
|
...and this would be reported:
|
||
|
```js
|
||
|
// message: Using exported name 'bar' as identifier for default export.
|
||
|
import bar from './foo.js';
|
||
|
```
|
||
|
|
||
|
For post-ES2015 `export` extensions, this also prevents exporting the default from a referenced module as a name within that module, for the same reasons:
|
||
|
|
||
|
```js
|
||
|
// valid:
|
||
|
export foo from './foo.js'
|
||
|
|
||
|
// message: Using exported name 'bar' as identifier for default export.
|
||
|
export bar from './foo.js';
|
||
|
```
|
||
|
|
