Kinetic adds view-composer-like features to the Inertia.js Laravel adapter. Like Laravel view composers, Kinetic can bind data each time a component is rendered from a single location.

Within a service provider, you can call the composer() method to define Inertia composers:

 1// In a service provider
 2public function boot()
 3{
 4    // Class-based composer..
 5    Inertia::composer('User/Profile', UserComposer::class);
 6}
 7 
 8// Composer class
 9class UserComposer
10{
11    public function compose(ResponseFactory $inertia)
12    {
13        $inertia->with('list', [
14            'foo' => 'bar',
15            'baz' => 'buzz'
16        ]);
17    }
18}

The composer() method supports closure-based composers as well:

1Inertia::composer('User/Profile', function (ResponseFactory $inertia) {
2    $inertia->with([
3        'post' => [
4            'subject' => 'Hello World!',
5            'description' => 'This is a description.'
6        ]
7    ]);
8});

With composers defined in a service provider, your props will include the composing data when you call render():

1// Includes bound data from `Inertia::composer('User/Profile')`
2Inertia::render('User/Profile');
