I have created a map block plugin that works more or less, but I'm having trouble understanding how to load the map script when/after the block is inserted. If I reload the page after inserting/saving, or if I load the public view, the map script loads as expected (since I've enqueued the scripts and styles via PHP). Normally, I would attach the script to some kind of DOM event, but I realize that Gutenberg/React handles things differently.
So my questions are:
- How do I load a script (remote or inline) immediately after my block is inserted?
- How do I set block properties in a remote script that's been enqueued via PHP (i.e. using
props.setAttributes(), which isn't available to scripts located outside of my block registration)?
This is my first stab at Gutenberg/React, but here's what I'm working with at the moment. I may be missing some fundamentals.

This is how the scripts are currently enqueued...
function myplugin_blocks_cgb_block_assets() {
wp_enqueue_style(
'myplugin_blocks-cgb-style-css',
plugins_url( 'dist/blocks.style.build.css', dirname( __FILE__ ) ),
array( 'wp-editor' )
);
wp_enqueue_style(
'myplugin-leaflet-css',
'https://unpkg.com/[email protected]/dist/leaflet.css',
array()
);
wp_enqueue_script(

}
add_action( 'enqueue_block_assets', 'myplugin_blocks_cgb_block_assets' );
