# import/no-named-as-default-member | |
⚠️ This rule _warns_ in the following configs: ☑️ `recommended`, 🚸 `warnings`. | |
<!-- end auto-generated rule header --> | |
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; | |
``` |
