Working with composer and views

Hi
I've little experience with Composer.
I could finally install IonAuth using Composer.
As requirements, it installs 37 packages while in dev stage

Code:

$ composer config minimum-stability dev
$ composer config repositories.ionAuth vcs [email protected]:benedmunds/CodeIgniter-Ion-Auth.git
$ composer require benedmunds/CodeIgniter-Ion-Auth:4.x-dev

What should I do once I finish developing the App to clean unused packages and not to upload the whole vendor folder?

Also, please note the location of IonAuth's view files

Code:

D:\www\myproj\vendor\benedmunds\codeigniter-ion-auth\Views\auth

What are the "best practices" to include those views in my already-built bs4 template? Should I move those views to App/Views/auth and then integrate my template into each view, right?
But I guess moving those views will break IonAuth composer's installation...

Thanks for any clarification you can give me about this
