How to execute code on every page load on laravel

I need to prepare a set of dates and store them in Session variables when the user reloads the page. This is done from the Controller. This is a problem because the app calls about 18 different controllers on each load, so I need to change the way these dates are stored.

I’ve thought about using a middleware but that would mean setting this middleware for each method where I load the view, otherwise it would still be loading this dates 18 times per call.
Also I’ve tried setting a rate limiter of one minute, but the reason I have to change the way this is done is because the dates mix up on successive calls, and this idea prevented that happening more than once a minute.

So I was wondering if there was a way of calling a method just once per view load or something aprox.

    1. Create a new Service Provider:
    php artisan make:provider DateServiceProvider
    1. Open config/app.php and add your service provider to the providers array:
    'providers' => [
    // ...
    AppProvidersDateServiceProvider::class,
],
    1. In the newly created DateServiceProvider, use the boot method to set up your dates:
    namespace AppProviders;

use IlluminateSupportServiceProvider;
use Session;

class DateServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap services.
     *
     * @return void
     */
    public function boot()
    {
        if (!Session::has('dates')) {
            // Calculate your dates here...
            $dates = '...';

            // Store the dates in session
            Session::put('dates', $dates);
        }
    }

    /**
     * Register services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

    Now, you can access these dates from any controller, middleware, or view via the session:

    $dates = session('dates');

    In Laravel, you can execute a method just once per view load by using the @once directive provided by Blade, Laravel’s templating engine. This directive ensures that the code within it is only executed once for each view rendering. Here’s how you can use it:

    @once
    <?php
        // Call your method here
        myMethod();
    ?>
@endonce

    If I understood it right this is what you want.
