VitalRouter

VitalRouter, is a source-generator powered zero-allocation fast in-memory messaging library for Unity and .NET.

It can declaratively do async handler/async middleware/sequence control, etc., and could serve as a thin framework to promote unidirectional control flow.

In games, or complex GUI application development, patterns such as central event aggregator/message broker/mediator are powerful patterns to organize N:N relationships. Assembling an asynchronous function pipeline can be even more effective.

Features

• Zero allocation message passing
• Thread-safe
• Pub/Sub, Fan-out
• Async / Non-async handlers
• Fast declarative routing pattern
• Naive event handler pattern
• Async interceptor pipelines
  • Parallel, queueing, or other sequential control.
• DI friendly. Also support without DI.
• Optional Extensions
  • UniTask support
  • R3 integration
  • MRuby scripting

Installation

Unity

• Prerequirements:
  • Unity 2022.2+
    • This limitation is due to the use of the Incremental Source Generator.
• Optional
  • Install UniTask >= 2.5.5
    • If UniTask is installed, VITALROUTER_UNITASK_INTEGRATION flag is turned on and the optimized GC-free code is executed.
    • See UniTask Integration section for more details.
  • Install VContainer >= 1.15.1
    • For bringing in DI style, VitalRouter supports Integration with VContainer, a fast and lightweight DI container for Unity.
    • See DI section for more details.

Then, add git URL from Package Manager:

https://github.com/hadashiA/VitalRouter.git?path=/src/VitalRouter.Unity/Assets/VitalRouter#1.6.0

.NET

THe following NuGet packages are available.

Package	Latest version
VitalRouter
VitalRouter.Extensions.DependencyInjection

[!NOTE] For Unity, use of the above package is recommended instead of Nuget.

Async interceptor pipeline

Pipelining of async interceptors for published messages is possible. This is a general strong pattern for data exchange.

UniTask Integration

UniTask is a fast async/await extension for Unity. VitalRouter actively supports UniTask.

R3 Integration

R3 is the next generation Reactive Extensions implementation in the C# world. It is an excellent alternative to asynchronous streams, but also an excellent alternative to local events.

VitalRouter supports the ability to work with R3.

MRuby scripting?

It is very powerful if the publishing of commands can be controlled by external data.

For example, when implementing a game scenario, most of the time we do not implement everything in C# scripts. It is common to express large amounts of text data, branching, flag management, etc. in a simple scripting language or data format.

VitalRouter offers an optional package for this purpose before integrating mruby. (blog / blog (Japanease)

Fiber in mruby and async/await in C# are fully integrated.
