Best way to fetch Blogger site feeds

Fetching feeds from a Blogger site can be a powerful way to manage and display your blog content. Whether you want to display blog posts, pages, or comments directly in your application or website, using a structured library can make this process seamless. The @deox/blogger-feed library is a handy tool for fetching Blogger site feeds effortlessly. In this guide, we’ll explore how to set it up, fetch data, and use the library’s various features.

Introduction to @deox/blogger-feed

The @deox/blogger-feed library provides a straightforward way to access and manage Blogger feeds. You can use it to retrieve posts, pages, comments, and general information about a Blogger blog. It offers flexibility with its options, allowing you to specify things like the number of results to retrieve, making it a great tool for developers looking to integrate Blogger data into their projects.

Installation

To start using @deox/blogger-feed, you can include it directly in your project using a CDN. Here’s how:

<script src="https://cdn.jsdelivr.net/npm/@deox/blogger-feed@0.0.5/dist/blogger-feed.min.js"></script>

Setting Up the Blogger Feed

To start fetching feeds, you’ll need to initialize an instance of BloggerFeed by passing in the Blogger site URL. You can also configure it with the jsonp option if you prefer to make cross-domain requests using JSONP (JSON with Padding). This is useful for situations where CORS (Cross-Origin Resource Sharing) restrictions apply.

<script src="https://cdn.jsdelivr.net/npm/@deox/blogger-feed@0.0.5/dist/blogger-feed.min.js"></script>
  
<script>
const feed = new BloggerFeed("https://your-blogger-site.blogspot.com", { jsonp: true });

// ...
</script>

By setting jsonp: true, the library will use JSONP for fetching data, which can be particularly useful if you are working in environments with strict cross-origin policies.

Fetching Blog Information

The first thing you may want to do is retrieve information about the blog itself. This includes data like the title, description, and blog ID. You can retrieve blog information using the blog.get() method.

<script>
(async () => {
  const blog = await feed.blog.get(); // type: Blog
  console.log(blog);
})();
</script>

The result is a Blog object that contains details such as the blog’s name, description, URL, and more.

Fetching Posts

To retrieve posts, you can use the posts.list() method. This method accepts options such as maxResults to specify the number of posts to retrieve.

<script>
(async () => {
  const posts = await feed.posts.list({ maxResults: 5 }); // type: Post[]
  console.log(posts);
})();
</script>

The above example fetches up to 5 posts and stores them in the posts variable. Each item in the array is a Post object containing fields like title, content, author, and publication date.

Fetching Pages

In addition to posts, the library also allows you to fetch pages with the pages.list() method. This function does not require additional options, although you can apply filters as needed.

<script>
(async () => {
  const pages = await feed.pages.list(); // type: Post[]
  console.log(pages);
})();
</script>

The pages variable contains an array of Post objects, each representing a page from the Blogger site. This feature is especially useful if you want to display static content or specific pages alongside blog posts.

Fetching Comments

The @deox/blogger-feed library also supports fetching comments. To retrieve comments, use the comments.list() method, which accepts options like maxResults.

<script>
(async () => {
  const comments = await feed.comments.list({ maxResults: 20 }); // type: Comment[]
  console.log(comments);
})();
</script>

The comments array contains Comment objects with details like the comment’s content, author, and date. This can be useful if you want to display recent comments or analyze comment data.

Example Implementation

Here’s a complete example that combines all the previous steps to fetch the blog information, latest posts, pages, and comments using the CDN version of the library and the jsonp option.

<script src="https://cdn.jsdelivr.net/npm/@deox/blogger-feed@0.0.5/dist/blogger-feed.min.js"></script>

<script>
const feed = new BloggerFeed("https://your-blogger-site.blogspot.com", { jsonp: true });

(async () => {
  const blog = await feed.blog.get();
  console.log("Blog Info:", blog);

  const posts = await feed.posts.list({ maxResults: 5 });
  console.log("Recent Posts:", posts);

  const pages = await feed.pages.list();
  console.log("Pages:", pages);

  const comments = await feed.comments.list({ maxResults: 20 });
  console.log("Recent Comments:", comments);
})();
</script>
