Installation

You can install @deox/blogger-feed using a package manager like npm, yarn, or pnpm or by using a CDN.

Using npm (or other package managers)

If you're using a JavaScript project with a package manager, you can install @deox/blogger-feed with:

npm install @deox/blogger-feed

pnpm add @deox/blogger-feed

yarn add @deox/blogger-feed

Using CDN

Include the following script in your HTML file:

<script src="https://cdn.jsdelivr.net/npm/@deox/blogger-feed@0.0.10/dist/blogger-feed.min.js"></script>

Usage

To start fetching feeds, initialize an instance of BloggerFeed by passing in the Blogger site URL. 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 (only if running in browsers).

Using ES Modules

import { BloggerFeed } from "@deox/blogger-feed";

const feed = new BloggerFeed("https://your-blogger-site.blogspot.com", {
  // use jsonp to bypass CORS restrictions
  jsonp: true
});

// ...

Using CDN

<script src="https://cdn.jsdelivr.net/npm/@deox/blogger-feed@0.0.10/dist/blogger-feed.min.js"></script>

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

  // ...
</script>

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 feed.blog.get() method.

feed.blog.get().then((blog) => {
  console.log(blog);
});

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 feed.posts.list() method. This method accepts options such as maxResults to specify the number of posts to retrieve.

feed.posts.list({ maxResults: 5 }).then((posts) => {
  console.log(posts);
});

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 feed.pages.list() method. This function also accepts options similar to feed.posts.list() such as maxResults.

feed.pages.list().then((pages) => {
  console.log(pages);
});

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 feed.comments.list() method, which accepts options like maxResults.

feed.comments.list({ maxResults: 20 }).then((comments) => {
  console.log(comments);
});

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@0.0.10/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>
