Background output of "View Composer"

Background output of dynamic information on all pages

View Composers will be useful when some data is shared for many or all pages. Examples: navigation or a block with popular articles, etc. It is for such cases that Laravel provides an elegant solution. Also, a good point for performance is that without visual output, the compositor code also does not work. Let's create a template for the output:

resources/views/layouts/sidebar.blade.php

Let's add the code for the output of articles

@foreach ($articles as $article)
{{ $article->active_from }}
{{ $article->code }}
{{ $article->name }}
@endforeach

Let's call the template in the general website template (or any other):

...
@include('layouts.articles')
...

Add the provider to the "providers" array of the configuration file "config/app.php ":

...

'providers' => [
...
AppProvidersComposerServiceProvider::class,
],
...

Creating a provider:

app/Providers/ComposerServiceProvider.php

Adding our new View Composer to it:

namespace AppProviders;

use IlluminateSupportFacadesView;
use IlluminateSupportServiceProvider;

class ComposerServiceProvider extends ServiceProvider
{
public function register()
{
}

public function boot()
{
View::composer(
'layouts.sidebar',
'AppHttpViewComposersShowSideBar'
);
}
}

Creating View Composers:

app/Http/ViewComposers/ShowSideBar.php

We add the code for getting articles to it:

namespace AppHttpViewComposers;

use App;
use AppModelsArticle;
use IlluminateViewView;

class ShowSideBar
{
public function compose(View $view)
{
$articles = Article::where('active', 1)
->orderBy('date')
->take(10)
->get();

return $view->with(['articles' => $articles]);
}
}

Now on every page of the site you should see a list of articles and you don't need to repeat getting it in the page controllers.
