Block Catalog

Keep track of which Gutenberg Blocks are used across your site.

Features

• Find which blocks are used across your site.
• Fully Integrated with the WordPress Admin.
• Use filters to see Posts that use a specific block.
• Find Posts that use Reusable Blocks.
• Use the WP CLI to quickly find blocks from the command line.
• Use custom WordPress filters to extend the Block Catalog.
• Find block usage on a Multisite network.
• Export block catalog data to a CSV file via the WP CLI.

Installation

• Block Catalog can be installed like any other plugin from the WordPress.org plugin directory.
• You can also install the plugin manually by downloading a zip file.
• To install the plugin using composer and wpackagist, add the following to your composer.json.

"wpackagist-plugin/block-catalog":"~1.3.1"

Getting Started

On activation, the plugin will prompt you to index your content. You need to do this first before you will be able to see the various blocks used on your site. You can also go to WP-Admin > Tools > Block Catalog to do this yourself.

Alternately, you can run the WP CLI command wp block-catalog index to index your content from the command line.

Once indexed, you will be able to see the different blocks used on your site in the Block Catalog Taxonomy.

Navigating to any Block Editor post type will also show you the list of blocks present in a post.

You can also filter the listing to only show Posts that have a specific block.

Frequently Asked Questions

1) Why does the Plugin require indexing?

Block Catalog uses a taxonomy to store the data about blocks used across a site. The plugin can build this index via the Tools > Block Catalog screen or via the WP CLI wp block-catalog index. After the initial index, the data is automatically kept in sync after any content updates.

2) Why does the name displayed in the plugin use the blockName attribute instead of the title?

If your blocks are registered on the Backend with the old register_block_type API, you may be missing the title attribute. The newer register_block_type_from_metadata uses the same block.json on the FE and BE which includes the Block title.

When the plugin detects such a missing title, it uses the blockName suffix instead. eg:- xyz/custom-block will display as Custom Block.

To address this you need to update your custom block registration. If this is outside your control, you can also use the block_catalog_block_title filter hook to override the title as seen below.

<?php

add_filter( 'block_catalog_block_title', function( $title, $block_name, $block ) {
	$map = [
		"xyz/custom-block" => "My Custom Block",
	];

	if ( ! empty( $map[ $block_name ] ) ) {
		return $map[ $block_name ];
	}

	return $title;
}, 10, 3 );

Support Level

Stable: 10up is not planning to develop any new features for this, but will still respond to bug reports and security concerns. We welcome PRs, but any that include new features should be small and easy to integrate and should not include breaking changes. We otherwise intend to keep this tested up to the most recent version of WordPress.
