This is a template repository from which you can create your own package to share blade components across multiple Laravel apps. If you've never used a template repository, here are some basic instructions.
If you're going to make your library public (put it in packagist), you must edit composer.json and refactor the classes to reflect your own vendor namespace. If you're just going to use it internally and pull it in from somewhere other than Packagist, you can leave the namespace as is if you like.
I have demonstrated a very simple blade component at src/Components/ExampleComponent.php that uses resources/views/components/example_component.blade.php. The component is used in resources/views/example.blade.php.
Create New Component Classes: src/Components/{MyNewComponentName}.php
Create New Component Templates: resources/views/components/{my_new_component_name}.blade.php
I tested my example component using Nuno Maduro's excellent Laravel Mojito package. It makes TDDing components in this library very easy.
