A demo application with a DDD membership domain.
A working version of this demo be run locally using either Docker or Vagrant.
Simply clone the repository:
git clone git@github.com:keithmifsud/laravel-ddd-demo.git
and install composer's dependencies:
composer install
Create a database and update a copy of the .env.example file:
mysql -u yourusername -p
## enter your password
create database databasename;
exit
## copy the example file
cp .env.example .env
## Fill in the details in .env
## Then migrate the database tables
php artisan migrate
## Generate an application key if you haven't yet supplied one in .env
php artisan key:generateThe purpose of this demo is the code base itself. However, you can still register, login and update your profile. This process is intuitive once the application is running.
In this demo, you can study the separation of layers as follows:
The Domain Layer holds the "Business Logic". In this example, we have two contexts. One is a "Common" domain which is simply a helper domain with extensible objects. Other Bounded Contexts can have the Common domain as a dependency.
The main context for this demo, is the Member domain which is also tested here Unit Tests.
You may also notice the application of the Repository Pattern. The Domain depends on repository interfaces and not concrete implementations.
This layer handles concrete implementations related to infrastructure requirements. For the purpose of this demo, we only have Database requirements, however, in general applications you'll have other requirements such as Mailing services and external APIs.
The Application Layer is provided by the Laravel Framework. However, the Repository Pattern is also applied here. This Layer is the glue in between the Domain and the Infrastructure layers.
Please also note that the HTTP Controllers do not handle any logic which is not related to the request or response. In this Demo, I've used Application Services to handle all internal processes with the Domain and the Infrastructure.
