# Using wp_localize_script for a block script

 * Hi,
 * I am developing a Gutenberg block using the [@wordpress](https://wordpress.org/support/users/wordpress/)/
   create-block tool. In the block.json I added a frontend script through
 *     ```wp-block-code
       "viewScript": [
           "file:./hwscript.js",
           "hbw-words-script"
       ],
       ```
   
 * Since register_block_type registers and enqueues the script using the data from
   block.json, how can I use wp_localize_script without enqueuing again the hwscript.
   js file?

 * When we enqueue a script, the resulting HTML link tag’s ID attribute is the script’s
   registration handle with “-js” appended. Look through a page’s source HTML code
   for something similar for your hwscript.js file. It may not be the same for block
   scripts, but if it is, you can deduce the original registration handle.
 * Rather hacky, but you could bypass the usual localization process and directly
   output the script assignments you need within an inline `<script>` block from
   the ‘wp_print_scripts’ action hook.
 * Disclaimer: there may be a “right” way to do this that I’m unaware of, but one
   of these two should work for you, if not entirely “proper”.

 * Hi bcworkz,
 * You are right, I found the handle through the id attribute of the HTML tag. I
   was downright convinced that the value in the second element of the “viewScript”
   array was the handle of the script, so what is supposed to be that string?
 * Thanks

 * Good question! I have no idea, sorry. After a bit of research, I think it’s an
   alternative way of referencing a script that is already registered. With
 *     ```
       "viewScript": [
           "file:./hwscript.js",
           "hbw-words-script"
       ],
       ```
   
 * you’re saying enqueue both hwscript.js and the script registered as “hbw-words-
   script”. It’s not a handle for your file, it’s a handle of some other file to
   be enqueued as well. If such a registration does not exist, it’s probably ignored.
 * I decided this is the case from [https://developer.wordpress.org/block-editor/reference-guides/block-api/block-metadata/#wpdefinedasset](https://developer.wordpress.org/block-editor/reference-guides/block-api/block-metadata/#wpdefinedasset)

 * I think you are right. Anyway, the documentation is not clear about this. I managed
   to use wp_localize_script with the handle I found on the HTML script tag.

 * Thanks [@bcworkz](https://wordpress.org/support/users/bcworkz/). I know it’s 
   not recommended but I went with
 *     ```wp-block-code
           if (!empty($this->data)) {
             wp_localize_script('blocknamespace-' . $this->name. '-editor-script', $this->name, $this->data);
           }
       ```
   
 * And it works like a charm.
