import/export

💼 This rule is enabled in the following configs: ❗ errors, ☑️ recommended.

Reports funny business with exports, like repeated exports of names or defaults.

Rule Details

```js export default class MyClass { /…/ } // Multiple default exports.

function makeClass() { return new MyClass(…arguments) }

export default makeClass // Multiple default exports. ```

or

```js export const foo = function () { /…/ } // Multiple exports of name ‘foo’.

function bar() { /…/ } export { bar as foo } // Multiple exports of name ‘foo’. ```

In the case of named/default re-export, all n re-exports will be reported, as at least n-1 of them are clearly mistakes, but it is not clear which one (if any) is intended. Could be the result of copy/paste, code duplication with intent to rename, etc.
