Suggested meaning

Designates that an API item is not planned to be used by third-party developers. The tooling may trim the declaration from a public release. In some implementations, certain designated packages may be allowed to consume internal API items, e.g. because the packages are components of the same product.


 * Represents a book in the catalog.
 * @public
export class Book {
   * The title of the book.
   * @internal
  public get _title(): string;

   * The author of the book.
  public get author(): string;

In this example, inherits its @public designation from the containing class, whereas Book._title is marked as “internal”.
