--- description: "Disallow empty exports that don't change anything in a module file." --- > 🛑 This file is source code, not the primary documentation location! 🛑 > > See **https://typescript-eslint.io/rules/no-useless-empty-export** for documentation. ## Rule Details 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](https://www.typescriptlang.org/docs/handbook/modules.html) 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. Examples of code for this rule: ### ❌ Incorrect ```ts export const value = 'Hello, world!'; export {}; ``` ```ts import 'some-other-module'; export {}; ``` ### ✅ Correct ```ts export const value = 'Hello, world!'; ``` ```ts import 'some-other-module'; ``` ## Options ```jsonc // .eslintrc.json { "rules": { "@typescript-eslint/no-useless-empty-export": "warn" } } ``` This rule is not configurable.
