Pagination

List methods return a pagination object, not a bare array. The returned object includes:

• items — the current page of entries
• itemsPerPage — number of items returned in this page
• startIndex — index of the first item in the current page
• totalResults — total available entries
• selfUrl — current page URL
• previousUrl — previous page URL, if available
• nextUrl — next page URL, if available
• next() — fetch the next page or null
• previous() — fetch the previous page or null

Example:

const postsPage = await feed.posts.list({ maxResults: 5 });
console.log(postsPage.items.length);

const nextPage = await postsPage.next();
if (nextPage) {
  console.log(nextPage.items.length, "more posts");
}

Types

The package exports helpful type definitions for TypeScript users, including:

• Blog
• Post
• Comment
• Author
• Link
• Extended
• PostCommentInfo
• Feed

These types describe the structure of Blogger feed responses and are available from the package exports.

Browser Usage

To use the library in browser environments where CORS prevents direct JSON requests, enable JSONP mode:

const feed = new BloggerFeed("https://example-blog.blogspot.com", {
  jsonp: true,
});

Note: JSONP mode is only supported in browser environments.
