Features
The framework combines the concepts of event sourcing, CQRS and DDD to provide support for building applications that are scalable, maintainable, can work in distributed environments and are easy to integrate with outside world. As such, it takes some rather opinionated approaches on the design of certain parts of its architecture. Revo also offers other common features and infrastructure that is often necessary for building complete applications – for example, database migrations, event upgrades, authorizations, validations, messaging, integrations, multi-tenancy or testing. Furthermore, its extensions implement other useful features like entity history change-tracking, auditing or user notifications.
Domain-Driven Design
Building blocks for rich DDD-style domain models (aggregates, entities, value objects, domain events, repositories...)
.
Event Sourcing
Implementing event-sourced entity persistence with support for multiple event store backends (PostgreSQL, MSSQL, SQLite...).
A/synchronous event processing
Support for both synchronous and asynchronous event processing, guaranteed at-least-once delivery, event queues with strict sequence ordering (optionally), event source catch-ups, optional pseudo-synchronous event dispatch for listeners (projectors, for example).
Data access
Thin abstraction layer for easy data persistence (e.g. querying read models) using Entity Framework Core, Entity Framework 6, RavenDB, testable in-memory database or other data providers. Includes support for simple database migrations.
Projections
Support for read-model projections with various backends (e.g. Entity Framework Core (PostgreSQL, MSSQL, SQLite,...), Entity Framework 6, RavenDB...), automatic idempotency- and concurrency-handling, etc.
SOA, messaging and integration
Scale and integrate by publishing and receiving events, commands and queries using common messaging patterns, e.g. with RabbitMQ message queue (using EasyNetQ connector or Rebus service bus).
Sagas
Coordinating long-running processes or inter-aggregate cooperation with sagas that react to events (a.k.a. process managers).
Authorization
Basic permission/role-based ACL for commands and queries, fine-grained row filtering
.
Other minor features:
- History and change-tracking
- User notifications: event-based, with different output channels (mail, etc.), aggregation, buffering, etc.
- .NET Core 3.0+, .NET Standard 2.0+ & .NET 4.7.2+ support (with integration for ASP.NET Core and ASP.NET)
