How To Add Infinite Scroll To Shopify Blogs

To implement infinite scroll on your Shopify blog posts, you’ll need to use JavaScript/jQuery along with Shopify’s AJAX API to load more posts as the user reaches the end of the current post. Follow these steps to achieve infinite scrolling:

Add jQuery to your theme (if not already included):

In your Shopify admin, go to Online Store > Themes, click on “Actions” > “Edit code” for your active theme. Under the “Layout” folder, open the “theme.liquid” file. Add the following code before the closing </head> tag to include the jQuery library:

{% if template.name contains 'article' %}
<script src="https://code.jquery.com/jquery-3.6.0.min.js" integrity="sha384-KyZXEAg3QhqLMpG8r+Knujsl5/1ioA4yWfXJFg39goSap2FdUTD/8zWx4YNv4Gp4" crossorigin="anonymous"></script>
{% endif %}

Create a new file for the infinite scroll script:

In the “assets” folder, click “Add a new asset” and create a new JavaScript file called “infinite-scroll-blog.js”.

Add the infinite scroll script:

Paste the following JavaScript/jQuery code into the “infinite-scroll-blog.js” file:

$(document).ready(function() {
  let currentPage = 1;
  let isLoading = false;

  function loadNextPage() {
    if (isLoading) return;

    isLoading = true;
    currentPage++;

    $.ajax({
      url: '/blogs/{{ blog.handle }}',
      data: { page: currentPage },
      dataType: 'html',
      success: function(response) {
        const posts = $(response).find('.blog-posts-wrapper .grid__item');
        if (posts.length) {
          $('.blog-posts-wrapper').append(posts);
          isLoading = false;
        } else {
          $(window).off('scroll', onScroll);
        }
      },
      error: function() {
        isLoading = false;
      }
    });
  }

  function onScroll() {
    const scrollBottom = $(document).height() - ($(window).scrollTop() + $(window).height());
    if (scrollBottom < 500) {
      loadNextPage();
    }
  }

  $(window).on('scroll', onScroll);
});

Replace .blog-posts-wrapper .grid__item with the appropriate selectors based on your theme’s structure. The .blog-posts-wrapper should be the container that wraps your blog posts, and .grid__item should be the individual blog post elements.

Include the infinite scroll script in your theme:

In the “theme.liquid” file under the “Layout” folder, add the following code before the closing </body> tag:

{% if template.name contains 'article' %}
  <script src="{{ 'infinite-scroll-blog.js' | asset_url }}" defer="defer"></script>
{% endif %}

Save your changes and test:

Save all your changes and open a blog post in your store. Scroll down, and you should see the next blog posts being loaded automatically as you reach the end of the current post.

By following these steps, you can implement infinite scroll on your Shopify blog posts, providing a seamless browsing experience for your readers as they finish one blog post and automatically load the next.
