Registering multiple custom gutenberg blocks in a plugin with webpack build
It should be enough to define the build-JS with wp_register_script() and all dependencies and then register each block with register_block_type():
function plugin_slug_register_blocks() { // Register build.js wp_register_script( 'plugin-slug-blocks', plugins_url( 'build.js', __FILE__ ), array( 'wp-blocks', 'wp-element', 'wp-data' ) ); // Register Block 1 register_block_type( 'plugin-slug/block-name-1', array( 'editor_script' => 'plugin-slug-blocks', ) ); // Register Block 2 register_block_type( 'plugin-slug/block-name-2', array( 'editor_script' => 'plugin-slug-blocks', ) );}add_action( 'init', 'plugin_slug_register_blocks' );Besides editor_script, register_block_type() also accepts style and editor_style as arguments for the CSS files. If it is a dynamic block, you can also pass a render function with render_callback.
