How is the function exported? Is it a default export or a named one?

Question

RepoPilot · Accepted Answer

The function is exported as a **default export**.

You can see this in [index.js:L1], where the function is defined as:

```js
export default function escapeStringRegexp(string) {
```

This is also confirmed in the TypeScript definitions at [index.d.ts:L16-L17]:

```ts
export default function escapeStringRegexp(string: string): string;
```

And in the package.json configuration at [package.json:L11], the exports field points to the main file:

```json
"exports": "./index.js",
```

The usage examples in the README at [readme.md:L16-L17] also demonstrate this default export pattern:

```js
import escapeStringRegexp from 'escape-string-regexp';
```
