## eventric storage definition

Definition of the [eventric](https://github.com/efacilitation/eventric) storage interface
and feature specs which can be executed for storage implementations.


## API

eventric storage implementations must conform to the following interface:


### saveDomainEvent(domainEvent)

Saves a domain event into the stores and returns a promise which resolves after saving


### findDomainEvents({aggregateId, startingAtTimestamp})

Searches for domain events in the storage and returns a promise which resolves with the found domain events.
If an aggregate id is specified, only domain events with matching property aggregate.id must be returned.
If a timestamp is specified, only domain events with property timestamp equal of greater must be returned.


### getProjectionStore(projectionName)

Returns a promise which resolves with a unique store for a given projection name.

**Note:** This is storage implementation specific.

### clearProjectionStore(projectionName)

Clears the unique store for a given projection name and returns a promise which resolves after clearing

**Note:** This is storage implementation specific.


## Running feature specs inside storage implementations

The feature specs can be executed to verify a storage implementation is conforming to the above defined interface:

```coffeescript
eventricStorage = require 'eventric-storage'
eventricStorage.runFeatureSpecs()
```

**Note:** The specs require mocha.
