Using Laravel as N tier Architecture

Question

I am new to Laravel and I see MVC pattern here, I would like to know the best practice to active N-tier architecture in Laravel.

For example: Controller, Business Logic, Data Access layer (assuming Model in Laravel), Presentation Layer (DTO's used as JSON response)

Where do I fit Business Logic and DTO's in Laravel?

Your diagram already shows where to put the business logic (more or less). — Robert Harvey, Jan 04 '20 at 21:00
I mean in Laravel where should I add that, means shall i create BL directory and and some classes, etc.? — Sharad Soni, Jan 04 '20 at 21:01
Hence wanted an opinion on what is the best practice we can use in Laravel, or is there anything Laravel provides OOB to support this. — Sharad Soni, Jan 04 '20 at 21:03
Asking for "best practices" is [not the best way to spend your time here](https://meta.stackexchange.com/a/142354). The "best practice" is the one that most effectively meets your specific requirements. Ask us about a specific problem you are having. — Robert Harvey, Jan 04 '20 at 21:05
Thanks for the reference, but I have already gone through the complete answer in detail before asking question here. — Sharad Soni, Jan 04 '20 at 21:11
Then what are you confused about? Standing up a BL folder and writing some classes is as good a strategy as any other. — Robert Harvey, Jan 04 '20 at 21:11

The business logic might be in many places on Laravel:

In the controller itself
In Events and Event Listeners
In Services
In Jobs (queued or not)

There many ways to do it, it's up to you decide which fits to each case. If you try following SOLID Principles you will fell the necessity to use some of this options.

For the presentation layer, you can use Laravel API Resources, since it provides a simple way to transform your data and output as JSON in a standardized format.

Thanks for your help. My ideology is to not write logic in controllers. I think, Logic in Events might not fit my requirements. I will try out Services though Also, jobs are useful but not the place where I am looking for, Have read about API resources, will try it out that too. So services and API resources is what I am thinking now. – Sharad Soni Jan 04 '20 at 21:21
