Create Related Content Block

[kevinfodness]

Description

Create a block that can be used with full-site editing to display a list of related posts. Out of the box, it should display 3 posts in a horizontal row.

Use Case

As an editor, I want related posts to appear below the post content on an article page.

Acceptance Criteria

• This issue builds on the plugin templates structure defined in Create Plugin Templates Feature #51
• The block should be able to be placed below post content using full site editing and should display a list of 3 related posts horizontally in a row, containing the featured image and post title, both of which should link to the post.
• Add to the single post template created in create-wordpress-theme

Technical Details

• This block should assume that Elasticsearch Extensions is installed, active, indexed, and configured.
• Use a More Like This query in Elasticsearch to populate the list of posts.
• Ensure that the current post is not in the list of related posts (it shouldn't be, but confirm).
• Match based on post title, post content, categories, and tags.
• The block should be placed in plugin-templates/blocks/theme-related-content and the category for the block should be theme.

After speaking to @jakewrfoster we're blocked on this issue until alleyinteractive/elasticsearch-extensions#42 is resolved. This will allow us to leverage elasticsearch-extensions for our "more like this" query.
