Answer 1

There are two ways you could do this

1. Using your start files

you could register it in app/start/global.php

From the laravel docs

Your application's start files are stored at app/start. By default, three are included with > your application: global.php, local.php, and artisan.php.

But I prefer using the global.php for including other files so as not to populate the global.php

In this context (registering view composers), you could create a file 'app/composers.php' and include it in your global.php file like so:

require app_path() . '/composers.php';

2. Using Service Providers

Create a service Provider. (Sample code below)

class ComposerServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->registerUserComposer();
    }

    protected function registerUserComposers()
    {
        $this->app['view']->composers([
            'UserComposer@currentUser' => [
                'view1', 'view2'
            ],
        ]);
    }
}

Then add an entry into the 'providers' array of your app/config/app.php

'providers' => array(
    ....

    'ComposerServiceProvider'
)
