Laravel HMVC Structure - Sample Project

A sample project, building and using HMVC structure for Laravel 5.7+, 6, 7, 8.

What is HMVC?

You can find out here: HMVC - WIKI

Key advantages (M.O.R.E):

• Modularization: Reduction of dependencies between the disparate parts of the application.
• Organization: Having a folder for each of the relevant triads makes for a lighter work load.
• Usability: By nature of the design it is easy to reuse nearly every piece of code.
• Extensibility: Makes the application more extensible without sacrificing ease of maintenance.

Other advantages

• Able to achieve Microservice with ease. Splitting up the Modules into Services would be blazing fast.
• In the Project itself it's like a Mono-Repo strategy.

Laravel HMVC Structure - this project

• Top - Base MVC - Laravel App
  • Module 1 MVC - Small Laravel App
  • Module 2 MVC - Small Laravel App
  • ...
  • Module n MVC - Small Laravel App

Module Structure

• ModuleName
  • Configs: Your config files here.
  • Http:
    • Controllers: Your controllers here.
    • Requests
  • Languages: your language files here (translation)
    • en
    • vi
    • ...
  • Libraries: your special library classes file here.
  • Models: your models here.
  • Views: your view file here.
  • Routes: all the routes of the module
    • routes.php: routes of this module.
  • Services: your service handlers here
  • Providers: Service Provider
  • Policies: policies of the module

So you can see, a Module is just a small Laravel Application. You don't have to create a full structure to make it work.

The most important part is: ServiceProvider. Without that we can't boot up the Module.

How to create a new module?

1. Create your module folder inside app/Modules
2. Inside your module folder, create folder that you need like the structure above (ServiceProvider, Views,...)
3. Create a ServiceProvider and register it in configs/app.php
4. Test your module

How to access View/Language/Config?

Module folder name is the alias name to let us load views, language text,...
Example: I have Home module. Alias: home

Load view

We need to insert module alias in the beginning like this:

return view('home::home.view', $arrData);

Get language (translation) text

trans('home::home.hello'); // Hello
__('home::home.world'); // World

Get Config Value

Just like normal config, you can get your config via your alias like this:

config('home.text'); // get 'text' in home alias

Migrations

How it works?

When you run php artisan migrate, it will run like this:

- Base/Core (database/migrations) first
- Thought each module
    - Module 1
    - Module 2
    - ...
    - Module n

Create migration

Just create migration file (Laravel format) in <ModulePath>/Migrations.

Note:

• Filename must be: yyyy_MM_dd_hhmmss_class_name_here.php (follow Laravel format)

Console Command registration

• Create your command in app/Modules/<insert_module_name/Console/Commands
• Open your module's ServiceProvider, register it in boot method like this:

$this->commands([
    MyCommand::class,
]);

Note: Older Laravel versions might not have this opportunity. The current project is using Laravel 5.7
