# import/no-named-as-default-member

|
Reports use of an exported name as a property on the default export.
|
|
|
|
Rationale: Accessing a property that has a name that is shared by an exported
|
|
name from the same module is likely to be a mistake.
|
|
|
|
Named import syntax looks very similar to destructuring assignment. It's easy to
|
|
make the (incorrect) assumption that named exports are also accessible as
|
|
properties of the default export.
|
|
|
|
Furthermore, [in Babel 5 this is actually how things worked][blog]. This was
|
|
fixed in Babel 6. Before upgrading an existing codebase to Babel 6, it can be
|
|
useful to run this lint rule.

## Rule Details
|
|
|
|
Given:
|
|
|
|
```js
|
|
// foo.js
|
|
export default 'foo';
|
|
export const bar = 'baz';
|
|
```
|
|
|
|
...this would be valid:
|
|
|
|
```js
|
|
import foo, {bar} from './foo.js';
|
|
```
|
|
|
|
...and the following would be reported:
|
|
|
|
```js
|
|
// Caution: `foo` also has a named export `bar`.
|
|
// Check if you meant to write `import {bar} from './foo.js'` instead.
|
|
import foo from './foo.js';
|
|
const bar = foo.bar;
|
|
```
|
|
|
|
```js
|
|
// Caution: `foo` also has a named export `bar`.
|
|
// Check if you meant to write `import {bar} from './foo.js'` instead.
|
|
import foo from './foo.js';
|
|
const {bar} = foo;
|
|
```
