Package realizes concept of event sourcing with Laravel framework. Package consists of two main elements: implementation of database-like event store and projection manager. Event store is a append-only storage dedicated for storing events. Projection manager allows to register projections and update them with generated stream of events. Installation ------------ [](#installation) To install the package via Composer, simply run the following command: ``` composer require desmart/laravel-event-sourcing ``` In order to use provided event store implementation, register service provider in your `config/app.php` file: ``` 'providers' => [ // ... DeSmart\EventSourcing\Laravel\EventStore\ServiceProvider::class, ] ``` In order to use projection manager, register service provider in your `config/app.php` file: ``` 'providers' => [ // ... DeSmart\EventSourcing\Laravel\Projections\ServiceProvider::class, ] ``` After registering service provider(s), run artisan command to publish configuration files: ``` php artisan vendor:publish ``` Configuration ------------- [](#configuration) Package adds two configuration files: `event-store.php` and `read-model.php`. ### `event-store.php` [](#event-storephp) Here you can configure: - which connection will be used to connect with your event store, - which event's payload serializer will be used. ``` return [ /* |------------------------------------------------------------------------------------- | Database Connection For Event Store |------------------------------------------------------------------------------------- | | Specify which database connection should be used for storing events in events store. | All database connections can be found in config/database.php configuration file. | */ 'connection' => null, /* |------------------------------------------------------------------------------------- | Event Store Payload Serializer |------------------------------------------------------------------------------------- | | Serializer used for serializing/deserializing event and it's payload. | | Payload is usually of array type. It is sufficient to store payload in | JSON format. | | Supported serializers: | - 'JsonSerializer' -> use for event store that does not have automatic json serialization/deserialization, like mysql databases | - 'ArraySerializer -> use for event store that has automatic json serialization/deserialization, like mongodb databases | */ 'serializer' => \DeSmart\EventSourcing\Laravel\EventStore\Serializers\JsonSerializer::class ]; ``` ### `read-model.php` [](#read-modelphp) Here you can register all projections that should be notified with stream of events. ``` return [ /* |-------------------------------------------------------------------------- | Read Model Projections |-------------------------------------------------------------------------- | | Array of projection classes. | | These projections will be notified about saved stream of events and they | can react with read model updates. | */ 'projections' => [] ]; ``` Event store implementation -------------------------- [](#event-store-implementation) This package's event store implementation was successfully used/tested with MySql database, MongoDB database as well as with mix of the two: one database served as an event store, where second was storing projections. Event store required structure (however different column types allowed) can be found [here](https://github.com/DeSmart/laravel-event-sourcing/blob/master/example/database/migrations/2016_05_16_125159_create_event_store_table.php). License ------- [](#license) Package is released under the MIT License (MIT). Please, check [LICENSE](https://github.com/desmart/laravel-event-sourcing/blob/master/LICENSE) for more details. Example usage ------------- [](#example-usage) For example use of event store as well as project manager, check [`example/`](https://github.com/desmart/laravel-event-sourcing/tree/master/example) directory. Additionally, package provides artisan command for rebuilding all projections: ``` php artisan projections:rebuild ``` ### Health Score 28 — LowBetter than 52% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity13 Limited adoption so far Community12 Small or concentrated contributor base Maturity58 Maturing project, gaining track record Bus Factor1 Top contributor holds 91.7% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
