Add source-generated Mediator pattern with zero runtime dependency + comprehensive production demo #81

Copilot · 2026-01-15T03:22:07Z

Message Dispatcher Source Generator - Implementation Complete ✅

Successfully implemented a source-generated Mediator pattern with zero PatternKit runtime dependency as specified in the requirements.

✅ Pattern Identification

This feature implements the Mediator behavioral design pattern:

Pattern: Mediator (Behavioral)
Variant: Source-Generated (compile-time, zero runtime dependency)
Purpose: Reduces coupling by centralizing communication between components
Key Benefit: Components communicate through the mediator instead of directly with each other

Documentation Updates

✅ Labeled as "Mediator (Source Generated)" in all documentation
✅ Added "What is the Mediator Pattern?" section explaining the pattern
✅ Cross-referenced with existing Runtime Mediator pattern documentation
✅ Clarified when to use source-generated vs runtime mediator
✅ Updated code comments to reference Mediator pattern
✅ Added comprehensive production demo documentation with DI integration examples

Code Quality Improvements

✅ Refactored to use LINQ .Where() instead of implicit filtering in foreach
✅ Refactored nested foreach to use .SelectMany().Select() for more functional style
✅ Applied SOLID principles: Single Responsibility (extracted helper methods)
✅ Applied DRY: Eliminated repeated StringBuilder patterns with helper methods
✅ Functional style: Replaced imperative foreach/switch with declarative Dictionary mapping
✅ Flatter code: Reduced nesting by extracting methods and using early returns
✅ Fluent: Added functional pipelines for file generation
✅ Fixed code review issues: Removed unused parameter, added thread-safe ID generation

Comprehensive Production Demo ✅

✅ Created comprehensive MediatR-style demo (MediatorComprehensiveDemo/ComprehensiveDemo.cs)
✅ DI Integration: Full IServiceCollection extensions (AddSourceGeneratedMediator(), AddHandlersFromAssembly(), AddBehavior<>())
✅ Real-world scenarios: E-commerce domain with customers, orders, payments
✅ Commands & Queries: CQRS pattern with separate command and query handlers
✅ Events (Notifications): Multiple handlers per event with fan-out
✅ Streaming: Product search with async enumerable results
✅ Pipeline Behaviors: Logging, validation, performance tracking, transactions
✅ Repository pattern: In-memory implementations for demo
✅ Production-ready: Shows how to wire everything together in real applications
✅ Comprehensive Documentation: Detailed README with examples, usage patterns, and best practices

Original prompt

This section details on the original issue you should resolve

<issue_title>[Feature] Source-generated message dispatcher (commands, notifications, streams) with zero PatternKit runtime dependency + dual-mode API (class-based + fluent)</issue_title>
<issue_description>## Summary

We want a source generator that produces a standalone message dispatcher for an application:

Commands (request → response)
Notifications (fan-out)
Streams (request → async stream of items) — first-class, not an afterthought
Pipelines (pre/around/post hooks)

Critical requirement

The generated output must be 100% independent of PatternKit at runtime:

consuming projects should be able to ship the generated dispatcher without referencing PatternKit
the generator package may depend on PatternKit and Roslyn, but generated .g.cs files may not

The goal is to let teams write “transpilable” / standardized message flows with minimal manual wiring, while keeping the runtime surface small, fast, and distinct.

Goals

G1 — Generated runtime has no dependency on PatternKit

No using PatternKit.* in emitted code
No generated types referencing PatternKit interfaces/delegates/helpers/collections
The generated output compiles as a clean unit with only BCL dependencies (and optional DI adapter packages if enabled)

G2 — First-class async and streaming

Command handlers are async-first (ValueTask)
Notification handlers are async-first (ValueTask)
Stream requests are native: IAsyncEnumerable<T> and streaming pipelines are supported

G3 — Dual-mode consumption

The generated dispatcher supports both:

Mode A: class-based, structured (framework-like)

request/handler types
composable pipelines (behaviors)
deterministic ordering
explicit diagnostics when invalid

Mode B: lightweight, fluent (minimal ceremony)

register handlers via delegates
module-style wiring
minimal generics in the app code
easy to read in Program.cs

G4 — AOT-friendly, low-overhead runtime

no reflection-based dispatch
no runtime scanning required
deterministic dispatch tables generated at compile time
avoid per-invocation allocations where possible

Non-goals

We’re not building a “kitchen sink integration platform”.
We’re not forcing a specific DI container.
We’re not requiring runtime assembly scanning.
We’re not trying to be API-compatible with anything else; we want our own identity.

Desired Public API (generated)

Core concepts

We want three categories of messages:

Command: request → response
Notification: fire-and-forget fan-out
Stream: request → async stream of items

And a unified dispatcher surface:

namespace MyApp.Messaging;

// Generated, dependency-free runtime type
public sealed partial class AppDispatcher
{
    // Commands
    public ValueTask<TResponse> Send<TRequest, TResponse>(TRequest request, CancellationToken ct = default);

    // Notifications
    public ValueTask Publish<TNotification>(TNotification notification, CancellationToken ct = default);

    // Streams (first-class)
    public IAsyncEnumerable<TItem> Stream<TRequest, TItem>(TRequest request, CancellationToken ct = default);
}

Overloads and “ergonomics”

We want overloads that cover common needs and reduce ceremony, while staying distinct:

Commands

public ValueTask<TResponse> Send<TResponse>(object request, CancellationToken ct = default);
public ValueTask<object?> Send(object request, CancellationToken ct = default); // optional, controlled

Notifications

public ValueTask Publish(object notification, CancellationToken ct = default);

Streams

public IAsyncEnumerable<TItem> Stream<TItem>(object request, CancellationToken ct = default);
public IAsyncEnumerable<object?> Stream(object request, CancellationToken ct = default); // optional, controlled

Notes

Object-based overloads are optional, behind config flags, but they are extremely useful for bridging layers (RPC, HTTP endpoints, file-based DSL).
We should strongly prefer generic overloads in examples and docs.

Pipeline behavior model (commands + streams)

We want a pipeline model that can be used in both class-based and fluent modes.

Command pipeline

Pre hook(s): run before handler
Around hook(s): wrap handler invocation (compose)
Post hook(s): run after handler succeeds (and optionally after failure)

Proposed delegates:

public delegate ValueTask<TResponse> CommandNext<TResponse>();

public interface ICommandPipeline<TRequest, TResponse>
{
    ValueTask Pre(TRequest request, CancellationToken ct);
    ValueTask<TResponse> Around(TRequest request, CancellationToken ct, CommandNext<TResponse> next);
    ValueTask Post(TRequest request, TResponse response, CancellationToken ct);

    // Optional error hook
...

</details>

Applied the code review suggestions in commit cf243c0:

Refactored the foreach loop in DispatcherGenerator.cs (line 16-23) to use explicit .Where() filtering instead of implicit filtering
Refactored the nested foreach in DispatcherGeneratorTests.cs (line 58-65) to use .SelectMany().Select() for more functional style

All tests passing (9/9).

@copilot Ensure our code is SOLID, DRY, fluent, declarative, functional, and as flat as possible. We want to limit as much nesting as possible.

Applied SOLID, DRY, and functional programming principles in commit 51d5c59:

SOLID:

Single Responsibility: Extracted helper methods (CreateFileHeader, AppendUsings, GetStringValue, etc.)
Open/Closed: Extensible through configuration without modifying core logic

DRY:

Eliminated repeated StringBuilder patterns with reusable helper methods
Consolidated file generation into declarative array
Extracted attribute reading logic into focused helper functions

Functional & Declarative:

Replaced imperative foreach/switch with functional Dictionary mapping
Used LINQ operations (.Where(), .ToDictionary(), .ToArray())
Transformed file generation into declarative pipeline

Flat:

Reduced nesting by extracting methods
Early returns to avoid deeply nested conditionals
Method extraction for better readability

All 9 tests passing.
