Types

A Book object is defined as follows:

type Book = {
    isbnSource: string;
    isbn10?: string;
    isbn13?: string;
    title?: string;
    authors?: string[];
    publishedDate?: string;
    genres?: string[];
    language?: string;
    pageCount?: number;
    thumbnail?: string;
    thumbnailSmall?: string;
    description?: string;
    publishers?: string[];
};

All provider functions have the following signature:

async function provider(isbn: string, fetchOptions?: FetchOptions): Promise<Book>;

Fetch options are a stripped down version of the RequestInit interface:

type FetchOptions = Omit<RequestInit, "body" | "method" | "keepalive">;
