Every Wordpress Editor Block

I've been doing some Wordpress theme development recently, and I couldn't find a decent reference for the blocks that come with the default Wordpress editor. So I'll keep one here.

Wordpress Core

I'm pulling these out of the Wordpress Source

core/audio
core/calendar
core/buttons
core/button – Only used inside core/buttons/
core/code
core/classic
core/cover
core/separator
core/embed
core/file
core/gallery
core/heading
core/html
core/image
core/list
core/paragraph
core/preformatted
core/pullquote
core/quote
core/table
core/verse
core/video
core/youtube
core/facebook
core/instagram
core/vimeo

Layout

core/block
core/columns
core/column – Only used inside core/columns.
core/more

Relational

core/archives
core/categories
core/latest-comments
core/latest-posts
core/media-text
core/missing
core/navigation-link
core/navigation
core/nextpage
core/group

Disabling blocks in the Post Editor

These identifiers are useful because they let you define a limited set of blocks that will be available in the post editor from your functions.php file.

function theme_allowed_block_types($allowed_block_types){
    return array(
		'core/paragraph',
		'core/heading',
        'core/list'
        # Add more identifiers here
	);
}
add_filter('allowed_block_types', 'theme_allowed_block_types');

In addition to this, I like to disable the default block CSS and style them myself instead. You do that by attaching a function to the wp_print_styles hook:

function remove_block_css()
{
	wp_deregister_style('wp-block-library');
}
add_action('wp_print_styles', 'remove_block_css');
