Camalote - Summarization block

Intro

This block is used to summarize the post content using an API endpoint. It can be used with any API endpoint that returns a summary of the content as an array.

The main idea is to use the API endpoint to summarize the content of the post, saving the response to post meta, and then display the summary as paragraph blocks based on such meta value.

These paragraph blocks are editable and the block listens for changes, automatically updating the meta value when saving the post.

It also allows you to regenerate the summary by clicking the "Generar resumen" button.

Caveats

This plugin doesn't handle custom field registration. It's up to the user to define the custom field and the field key in the WordPress installation.

Custom Field Registration example

function prefix_custom_field_registration() {
    register_meta( 'post', 'prefix_summarization_custom_field', array(
        'single'        => true,
        'type'          => 'array',
        'show_in_rest'  => array(
            'schema'    => array(
                'type'  => 'array',
                'items' => array(
                    'type' => 'string'
                ),
            ),
        )
    ) );
}
add_action( 'init', 'prefix_custom_field_registration' );
