Last update: 2020-10-02 13:19:05 UTC


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 tests

To run all the tests:


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
