# Exclude scripts – is there a way?

 * Is there any way to exclude certain scripts from being minified/optimized by 
   Phastpress?
 * The plugin is fantastic, but unfortunately it breaks the Google Tag Manager script
   on my site.
 * If I disable the “Minify scripts and improve caching” option, GTM works.
 * Ideally, it would be possible to exclude a script from being optimized, is this
   possible currently?

 * Hi Barold,
 * Thank you for trying out PhastPress.
 * Unfortunately, it’s not yet possible to exclude scripts from optimization. On
   the other hand, Google Tag Manager should work nevertheless, even with PhastPress
   enabled.
 * If you share the URL to your site, I could take a look and perhaps find out why
   it doesn’t work with script optimization enabled.

 * Hey Albert,
 * Thanks for the reply.
 * The site in question is [https://moodle.com/](https://moodle.com/)
 * Currently, the “Minify scripts and improve caching” setting is off.
    If you check
   the console on the homepage, you’ll notice a console log saying “tag fired”, 
   which is a test tag from GTM.
 * As soon as I turn the minify setting on that tag stops firing, which I assume
   means that GTM has stopped working.
 * Thanks 🙂

 * Hi Barold,
 * I’ve testing your GTM script on a local install of PhastPress, and I’m not seeing
   the same problem, unfortunately.
 * There is in fact a way to exclude scripts, but it requires editing the source
   code:
 * Would you be able to adjust the `<script>` tag to contain a `data-phast-no-defer`
   attribute? For example: `<script data-phast-no-defer> (GTM code here) </script
   >`. That should disable Phast for that particular script.

 * P.S.: I would recommend turning off other optimization software (except caching),
   such as WP Rocket and Cloudflare Rocket Loader, since those can conflict with
   PhastPress, and don’t offer important added functionality.

 * Thanks Albert, the data-phast-no-defer attribute worked perfectly!
    Much appreciated!

 * Barold,
 * I’m happy to hear that.
 * I have one additional tip for you: if I turn off JavaScript, the content of the
   page doesn’t render. See: [https://peschar.net/s/uIZwNqp108wl02EhPgDe/](https://peschar.net/s/uIZwNqp108wl02EhPgDe/)
 * That might be due to some animations in the theme, or some kind of lazy loading
   plug-in. In any case, if you change this so that the page can render without 
   JavaScript, it will improve the perceptual load speed of the page enormously.

 * Hey Albert,
 * Hope you’re well.
    I wanted to bring to your attention another issue related 
   to scripts.
 * The site we discussed above ([https://moodle.com](https://moodle.com)) uses a
   theme running the WPBakery (previously Visual Composer) page builder.
 * WPBakery seems to rely on 2-3 bits of javascript in order to begin generating
   page content.
 * As I understand, Phastpress delays loading of all javascript until page load 
   is complete. This causes WPBakery to not begin loading page content until very
   late.
 * Despite Pagespeed Insights scores remaining quite high, this causes a huge negative
   impact on perceived load time.
 * I don’t know if there’s a way to directly access the WPBakery scripts in order
   to add the “data-phast-no-defer” attribute!
 * So, I’ve had to disable Phastpress and move to another plugin for now.
 * A method within Phastpress to exclude specific theme/plugin scripts from being
   deferred (by name, or by directory, etc) without having to directly modifying
   the plugins themselves, would solve the issue – I don’t know if such a feature
   if possible!?
 * Thanks again,

 * Hi Barold,
 * Thanks for the report, and your detailed analysis.
 * Rendering shouldn’t be dependent on JavaScript (at least most of it), otherwise
   you’ll get this problem.
 * It would be possible to add the feature you describe (excluding scripts based
   on name or path). However, this goes against the zero configuration approach 
   PhastPress attempts to take. Furthermore, when you exclude certain scripts, you
   are likely to run into problems regarding dependencies. For instance, WP Bakery
   might require jQuery, and it’s not possible to keep track of this automatically.
 * For now, it’s not something I’m planning to implement.
 * –Albert
