Disallow empty exports that don't change anything in a module file.


Some problems reported by this rule are automatically fixable by the --fix ESLint command line option.

An empty export {} statement is sometimes useful in TypeScript code to turn a file that would otherwise be a script file into a module file. Per the TypeScript Handbook Modules page:

In TypeScript, just as in ECMAScript 2015, any file containing a top-level import or export is considered a module. Conversely, a file without any top-level import or export declarations is treated as a script whose contents are available in the global scope (and therefore to modules as well).

However, an export {} statement does nothing if there are any other top-level import or export statements in a file.

This rule reports an export {} that doesn't do anything in a file already using ES modules.

module.exports = {
"rules": {
"@typescript-eslint/no-useless-empty-export": "error"

Try this rule in the playground ↗


export const value = 'Hello, world!';
export {};
Open in Playground
import 'some-other-module';
export {};
Open in Playground


This rule is not configurable.

When Not To Use It

If you don't mind an empty export {} at the bottom of files, you likely don't need this rule.
