# Plugin Dev: update_option from JS script?

 * What’s the best way to get/set an option from within an enqueued JS script?
 * My best guess to `set` is to create a WP REST Route that sets/updates the option.
   I saw an SO answer from 2013 that said I could send a POST to `admin-ajax.php`
   to a handler I define, but I’m not sure if that’s out of date, or which is preferable.
 * For getting an option, should I use `wp_localize_script`/`wp_add_inline_script`?
   Is it worth setting up another REST endpoint to fetch the option?
 * Thank you!

 * Ajax methods are still completely valid. The API approach offers more validation
   options and is a more structured approach, hence by some reckoning the preferred
   approach. However, if the user is going to be logged in with adequate capability
   anyway, Ajax is more straight forward and to the point. It’s a perfectly valid
   approach.
 * Localize and inline script essentially do the same thing. Since wp_localize_script()
   directly relates to the script being enqueued, IMO it’s the preferred approach
   when your script is in an external file. If your entire script were fairly simple
   where it’s hard to justify an external file, then use wp_add_inline_script().
 * You could get option values through the API. It might be a reasonable approach
   if the desired option can’t be known when the page is first served. But if it
   can be fetched in PHP and passed through localize script, you’d avoid an additional
   API request, which is worth something of itself.
