Custom Post Type Templates
Here’s another entry
It came in rather late
My favourite’s not a block at all
but a CPT template.
function oik_block_CPT_template() {
$template = array();
$template[] = ['oik-block/blockinfo', [ 'className' => 'svg64' ] ];
$template[] = ['core/paragraph', ['backgroundColor' => 'very-light-gray'] ];
$template[] = ['core/more' ];
$template[] = ['core/heading', [ 'content' => "Screenshot" ] ];
$template[] = ['oik-block/fields', [ 'fields' => 'featured'] ];
$template[] = ['core/heading', [ 'content' => 'Example'] ];
$template[] = ['core/paragraph', ['placeholder' => 'Type / to choose the sample block' ]];
$template[] = ['core/spacer'];
$template[] = ['core/separator'];
$template[] = ['core/heading', [ 'content' => 'Notes'] ];
$template[] = ['core/list'];
return $template;
