FlyingPress minifies JavaScript files by default to improve load time and reduce file size. If a script breaks after minification, you can exclude it using the flying_press_exclude_from_minify:js filter.
Where to add this code
Add the snippet to one of the following:
Your theme’s
functions.phpfileA custom plugin
A plugin like Code Snippets
Example: Exclude JS files from minification
add_filter('flying_press_exclude_from_minify:js', function ($exclude_keywords) {
return [
'slider.js',
'custom/scripts/',
'my-theme',
'/themes/',
'/plugins/sample-plugin/'
];
});
How it works
The filter checks if any part of a JS file’s URL contains one of the keywords. Matching is partial and case-sensitive.
You can use:
File name:
'slider.js'matches/assets/js/slider.jsFolder path:
'custom/scripts'matches/custom/scripts/app.jsTheme-wide exclusion:
'/themes/'excludes all scripts from any themePlugin-wide exclusion:
'/plugins/'excludes all plugin JS filesSpecific plugin:
'/plugins/sample-plugin/'excludes only that plugin’s JS
Notes
Files excluded from minification can still be deferred or delayed unless excluded separately
Only exclude scripts if necessary—minification improves performance in most cases
