## 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:

```

### ✅ Correct

```

```ts
import 'some-other-module';
```
