Demo for Broadway - EventSourcing library for PHP

This repository contains a demo application to show how Broadway can be used within a Symfony application. The example is taken from the Practical Event Sourcing talk from Mathias Verraes.

For simplicity the demo uses the official DBAL event store and a custom DBAL read model implementation. You will need to have SQLite installed to run the demo.

Running the demo

composer install
bin/console broadway:event-store:create
bin/console broadway:read-model:create
bin/console server:run

This demo doesn't have a GUI, only an API with the following endpoints:

Method	Path	Description
POST	/basket	Pick up a new basket, returns the basketId
POST	/basket/{basketId}/addProduct	Add a product to a basket (productId and productName should be given as form fields)
POST	/basket/{basketId}/removeProduct	Remove a product from a basket (productId as form field)
POST	/basket/{basketId}/checkout	Check out a basket
GET	/advice/{productId}	Retrieve Other people also bought this list

# pick up a new basket
$ curl -X POST http://localhost:8000/basket
{
  "id":"1bd683ac-f75d-403f-babc-82ddcdb33de7"
}

# add products to the basket
$ curl -d "productId=2009&productName=Incredibad" -X POST http://localhost:8000/basket/1bd683ac-f75d-403f-babc-82ddcdb33de7/addProduct
$ curl -d "productId=2011&productName=Turtleneck+%26+Chain" -X POST http://localhost:8000/basket/1bd683ac-f75d-403f-babc-82ddcdb33de7/addProduct

{
  "purchasedProductId": 2011,
  "otherProducts": {
    "2009": 1,
    "2013": 1
  }
}

Running the tests

To run all the tests:

./vendor/bin/phpunit

Code structure

• Domain code can be found in src/Basket
• ReadModel code can be found in src/ReadModel
• Controllers can be found in src/Controllers

Note that there are two files for the services: services.yaml and domain.yaml. domain.yaml contains all the domain-specific services (CommandHandler, ReadModels, Repositories), while services.yaml contains domain-unspecific services (controllers etc).

The domain specific tests can be found in test/Basket and test/ReadModel

Note that there is a functional test in test/Functional
