# 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;
```
