# EventFlow.Example
[](#contributing)
DDD+CQRS+Event-sourcing examples using EventFlow following CQRS-ES architecture. It is configured with RabbitMQ, MongoDB(Snapshot store), PostgreSQL(Read store), EventStore(GES). It's targeted to .Net Core 2.2 and include [docker compose file](/build/docker-compose.yml).
## Event Sourcing/CQRS Architecture
The most common CQRS/ES architecture would look like following diagram
The example consists of the following concepts, each shown below
- Aggregates
- Command bus and commands
- Synchronous subscriber
- Event store ([GES](https://eventstore.com/))
- In-memory read model.
- Snapshots ([MongoDb](https://www.mongodb.com/))
- Sagas
- Event publising (In-memory, [RabbitMq](https://www.rabbitmq.com/))
- Metadata
- Command bus decorator, custom value object, custom execution result, ...
## Configuration
```csharp
var resolver = EventFlowOptions.New
.UseAutofacContainerBuilder(new ContainerBuilder())
.Configure(c => c.ThrowSubscriberExceptions = true)
.AddEvents(typeof(ExampleEvent))
.AddEvents(typeof(ResetEvent))
.AddCommands(typeof(ExampleCommand))
.AddCommands(typeof(ResetCommand))
.AddCommandHandlers(typeof(ExampleCommandHandler))
.AddCommandHandlers(typeof(ResetCommandHandler))
.ConfigureEventStore()
.ConfigureMongoDb(client, SNAPSHOT_CONTAINER_NAME)
.AddSnapshots(typeof(ExampleSnaphost))
.UseMongoDbSnapshotStore()
.RegisterServices(sr => sr.Register(i => SnapshotEveryFewVersionsStrategy.Default))
.RegisterServices(DecorateCommandBus)
.PublishToRabbitMq(RabbitMqConfiguration.With(new Uri(@"amqp://test:test@localhost:5672"), true, 4, "eventflow"))
.UseInMemoryReadStoreFor()
.AddJobs(typeof(ExampleJob))
.CreateResolver());
```
