| # import/export |
| |
| 💼 This rule is enabled in the following configs: ❗ `errors`, ☑️ `recommended`. |
| |
| <!-- end auto-generated rule header --> |
| |
| 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. |
