An actor system for C# built on Language-Ext, enabling functional concurrent programming with Redis persistence and JS integration.
Echo is an actor system for C# built on the Language-Ext functional framework, designed to simplify concurrent programming by packaging side-effects into functional computations using the actor model. It solves problems like race conditions and shared state access in C# applications, enabling massive concurrency with features like Redis persistence and JavaScript integration.
C# developers building concurrent or distributed systems who want to adopt functional programming principles to manage state and side-effects more effectively.
Developers choose Echo for its seamless integration with Language-Ext, robust actor model implementation, and additional modules like Redis persistence and JavaScript integration, which provide scalability and flexibility not found in standard C# concurrency tools.
Actor library for C# with additional modules that support persistence to Redis, as well as JS integration
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Seamlessly integrates with Language-Ext to package side-effects into functional computations, simplifying concurrent programming and avoiding race conditions as described in the README.
Includes Redis persistence for state management and clustering, enabling scalable distributed systems with role-aware dispatching for high availability.
Features routers and dispatchers for flexible load balancing and message distribution, with role-based dispatching that understands node aliveness in dynamic networks.
Provides WebSockets gateway via Owin and JavaScript API for client-side process execution, facilitating interactive, real-time applications across client and server.
Heavily reliant on the Language-Ext framework, making it unsuitable for projects not using functional C# patterns or unwilling to adopt additional dependencies.
Configuring Redis and cluster parameters requires specific knowledge and multiple steps, such as setting system names and roles, which can be daunting for new users.
The documentation advises using 'ask' for request/response sparingly, indicating that synchronous messaging is not a primary strength and may introduce performance overhead.
As a specialized library built on Language-Ext, it has a smaller community and fewer third-party integrations compared to mainstream concurrency tools like Akka.NET.
