# import/no-default-export | |
<!-- end auto-generated rule header --> | |
Prohibit default exports. Mostly an inverse of [`prefer-default-export`]. | |
[`prefer-default-export`]: ./prefer-default-export.md | |
## Rule Details | |
The following patterns are considered warnings: | |
```javascript | |
// bad1.js | |
// There is a default export. | |
export const foo = 'foo'; | |
const bar = 'bar'; | |
export default 'bar'; | |
``` | |
```javascript | |
// bad2.js | |
// There is a default export. | |
const foo = 'foo'; | |
export { foo as default } | |
``` | |
The following patterns are not warnings: | |
```javascript | |
// good1.js | |
// There is only a single module export and it's a named export. | |
export const foo = 'foo'; | |
``` | |
```javascript | |
// good2.js | |
// There is more than one named export in the module. | |
export const foo = 'foo'; | |
export const bar = 'bar'; | |
``` | |
```javascript | |
// good3.js | |
// There is more than one named export in the module | |
const foo = 'foo'; | |
const bar = 'bar'; | |
export { foo, bar } | |
``` | |
```javascript | |
// export-star.js | |
// Any batch export will disable this rule. The remote module is not inspected. | |
export * from './other-module' | |
``` | |
## When Not To Use It | |
If you don't care if default imports are used, or if you prefer default imports over named imports. |
