FileSystemDirectoryHandle does not have proper types

[Johan-Liebert1]

A lot of properties on FileSystemDirectoryHandle are not added to types.

Defined Types

/** Available only in secure contexts. */
interface FileSystemDirectoryHandle extends FileSystemHandle {
    readonly kind: "directory";
    getDirectoryHandle(name: string, options?: FileSystemGetDirectoryOptions): Promise<FileSystemDirectoryHandle>;
    getFileHandle(name: string, options?: FileSystemGetFileOptions): Promise<FileSystemFileHandle>;
    removeEntry(name: string, options?: FileSystemRemoveOptions): Promise<void>;
    resolve(possibleDescendant: FileSystemHandle): Promise<string[] | null>;
}

declare var FileSystemDirectoryHandle: {
    prototype: FileSystemDirectoryHandle;
    new(): FileSystemDirectoryHandle;
};

Not included in types

[tomayac]

This library doesn't define types for FileSystemDirectoryHandle, as you can see in index.d.ts. It uses whatever TypeScript already ships with. Maybe updating to the latest version fixes this for you.
