UtmMiddleware

File: src/Http/Middleware/UtmMiddleware.php
Alias: modularous.utm
Part of: modularous.core group

Captures UTM tracking parameters from the incoming request and shares them with Blade layout views.

What It Does

1. Calls Utm::getParameters() — this reads UTM params from the request and stores them in the session (see UtmParameters).
2. Registers a view composer for both layout views:

   view()->composer([
       'modularous::layouts.app-inertia',
       'modularous::layouts.master',
   ], function ($view) {
       $view->with('utmParameters', Utm::getParameters());
   });

Shared Variable

Variable	Type	Description
utmParameters	array	Captured UTM params from session: utm_source, utm_medium, utm_campaign, utm_term, utm_content

Notes

• Utm::getParameters() is called twice — once to capture (and persist to session) and once inside the view composer to retrieve. The second call reads from the session, so it is safe even if the current request doesn't have UTM params.
• Parameters persist in the session for the configured TTL (see UtmParameters).
• For Inertia pages, utmParameters is available in the Blade wrapper; pass it to the Vue app via storeData if needed.
