# get link()

## `CommonError.prototype.link`

The [`get`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get) accessor gets the link(to read more about the thrown error) by returning the [`#link`](https://docs.angular-package.dev/error/commonerror/properties/link) property of a specified object.

```typescript
public get link(): string | undefined {
  return this.#link;
}
