Wordpress: competent connection of scripts and styles for different pages?

Question

WordPress

Is it possible to connect scripts and styles somehow more competently for different pages and not in functions.php via if ( is_page ) ?

Answer 1

Binding through is_page works, but on large sites, life will become much more complicated when there are many custom post types, archive pages, etc., when, in addition to including js / css files, you also need to do localize_script ... In general, this code will quickly turn into pasta, which difficult to maintain.
I would do it the other way. What prevents adding a metabox to editing pages, in which you can additionally specify the path to arbitrary assets that are unique to this page? Store them, respectively, in meta or in options. Well, add a function that will check this value and, if it is not empty, load the necessary files.
Profit:
- the code is written once and it is universal for this task
- the code does not depend on IDs or page slugs at all
- when adding/removing assets, it is not necessary to maintain/update the code, it is enough to change the binding in the admin panel
