If you are working with laravel and still writing code like a junior developer without using some useful features for some structural methods is not that much good for big projects and your future opportunities.
I'd like to write about some useful techniques you can implement in your project development with laravel. It might be API or any web application.
The techniques are:
Why do we need to use these techniques in our development work? It will make your code more structured, Reusable and understandable to the next developer or yourself when you check down again for some bug fixing or an improvement.
What is a service class?In laravel, any class you write will work as a service class. It should be written to provide a complete implementation of a specific service or functionality. It is a beautiful showcase of object-oriented programming. You can have multiple services based on multiple functionality or operations. It is also used to encapsulate complex business logic. More discussion of service class here (Service Classes in Laravel)
What is trait?This is another use case of object oriented programming. When you cannot extend multiple classes at a time (specially in php) then you can use trait. It solves the problem by providing a way to reuse code across multiple classes without using inheritance. Trait also serves almost similar things as like service classes however, trait provides a set of methods that can be mixed into multiple classes to provide them with additional functionality. For details discussion about trade you can check this blog of mine.
