How to do dependency injection in livewire 3 form class?

Question

I have a Component called CreatePost

class CreatePost extends Component
{
    public PostForm $form;
 
    public function save()
    {
        $this->form->store(); 
 
        return $this->redirect('/posts');
    }
 
}

And Here is my PostForm:

class PostForm extends Form
{
    public $title = '';
 
    public $content = '';
 
    public function store() 
    {
        $this->validate();
 
        Post::create($this->all());
    }
}

Now in my PostForm store() method I want to inject my PostService to create a Post. What is the best way to do it.

Thanks

Best I could come up with is to Inject my PostService in boot() method of my Component and then pass it as a parameter in store() but I was hoping if there is a cleaner way to do it through ServiceProvider for example ?

Answer 1

Since I wanted to decouple PostForm from CreatePost component and also wanted to follow the DI principle so I made an interface of PostService and used that in the PostForm store() method. I used Laravel ServiceProvider to provide concrete implementation of Service class. It was so simple but didn't came in my mind.

app(PostServiceInterface::class)
