[Implementation Checklist](#implementation-checklist) +10. [Priority Matrix](#priority-matrix) + +--- + +## Library Overview + +### What is SimpleRouter? + +SimpleRouter is a navigation/routing library that provides: +- Stack-based navigation with forward/back support +- Route lifecycle events (OnRouteChanging, OnRouteChanged) +- Factory-based route creation with parameter support +- Platform-agnostic core with Avalonia-specific extensions +- View resolution and hosting for Avalonia applications + +### Architecture + +``` +Core Layer (SimpleRouter): +├── IRoute - Route interface +├── IRouter - Router interface +├── IRouterHost - Host interface +├── Router - Main router implementation +└── Events - Navigation event arguments + +Avalonia Layer (SimpleRouter.Avalonia): +├── RouteViewHost - Content control for displaying routes +└── ViewLocatorBase - Abstract view locator +``` + +### Target Audience + +- Desktop application developers using MVVM pattern +- Avalonia UI developers (primary) +- WPF developers (with custom implementation) +- Framework-agnostic usage possible + +--- + +## Strengths + +✅ **Clean Architecture** +- Well-defined interfaces with single responsibility +- Good separation of concerns between core and UI layers +- Framework-agnostic core design + +✅ **Good Test Coverage** +- 26 unit tests covering main scenarios +- Uses mocking appropriately +- Tests pass consistently + +✅ **Simple API** +- Intuitive navigation methods (NavigateTo, NavigateBack, NavigateToAndReset) +- Generic and type-based overloads +- Event-driven design + +✅ **NuGet Package Ready** +- Properly configured .csproj files +- Multi-targeting (netstandard2.1, net8.0) +- Package metadata configured + +✅ **CI/CD Setup** +- GitHub Actions for testing +- Automated builds on PR and push + +--- + +## Critical Issues + +### 🔴 Priority: CRITICAL + +#### 1. Memory Leak in RouteViewHost +**Location:** `SimpleRouter.Avalonia/RouteViewHost.cs:30` + +**Issue:** Event handler subscribed but never unsubscribed when Router changes or control is disposed. + +```csharp +router.OnRouteChanged += Router_OnRouteChanged; +``` + +**Impact:** Memory leaks in applications with dynamic router changes. + +**Fix Required:** +```csharp +protected override void OnPropertyChanged(AvaloniaPropertyChangedEventArgs change) +{ + base.OnPropertyChanged(change); + switch (change.Property.Name) + { + case nameof(Router): + // Unsubscribe from old router + if (change.OldValue is IRouter oldRouter) + { + oldRouter.OnRouteChanged -= Router_OnRouteChanged; + } + + // Subscribe to new router + if (change.NewValue is IRouter newRouter) + { + newRouter.OnRouteChanged += Router_OnRouteChanged; + NavigateToRoute(newRouter.Current); + } + break; + } +} +``` + +#### 2. Stack Limit Not Applied +**Location:** `SimpleRouter/Router.cs:12-15` + +**Issue:** Constructor accepts `stackLimit` parameter but never assigns it to `_stackLimit` field. + +```csharp +public Router(RouteFactory createRoute, int stackLimit = 50) +{ + _createRoute = createRoute ?? throw new ArgumentNullException(nameof(createRoute)); + // BUG: stackLimit parameter is ignored! +} +``` + +**Impact:** Stack limit is always 50 regardless of constructor parameter. + +**Fix Required:** +```csharp +public Router(RouteFactory createRoute, int stackLimit = 50) +{ + _createRoute = createRoute ?? throw new ArgumentNullException(nameof(createRoute)); + _stackLimit = stackLimit; +} +``` + +--- + +## Code Quality Issues + +### 🟡 Priority: HIGH + +#### 1. Unused Import +**Location:** `SimpleRouter/Router.cs:1` + +**Issue:** +```csharp +using System.Net.Sockets; // Not used anywhere +``` + +**Fix:** Remove the unused import. + +#### 2. Nullable Reference Type Warnings +**Locations:** Test files have 3 warnings for null literal conversions + +**Files:** +- `AvaloniaRouteViewHostTests.cs:17,53` +- `RouterTests.cs:303` + +**Fix:** Use `null!` or proper nullable annotations in tests. + +#### 3. Missing XML Documentation +**Issue:** Many public APIs lack XML documentation comments. + +**Examples:** +- `IRoute.RouteName` - No description +- `IRoute.RouterHost` - No description +- `Router` methods - Minimal documentation +- `Events.cs` - No documentation on event args properties + +**Impact:** IntelliSense provides limited help to library users. + +#### 4. Magic Numbers +**Location:** Throughout `Router.cs` + +**Examples:** +- Stack limit default of 50 (what's the rationale?) +- Stack index calculations using literals + +**Fix:** Add constants with descriptive names and documentation. + +--- + +## Missing Core Features + +### 🟡 Priority: HIGH + +#### 1. Navigation Guards/Middleware +**Description:** No way to prevent or intercept navigation. + +**Use Cases:** +- Authorization checks before navigating +- Unsaved changes confirmation +- Conditional navigation based on application state + +**Proposed API:** +```csharp +public interface INavigationGuard +{ + Task CanNavigateFrom(IRoute? current, IRoute? next); + Task CanNavigateTo(IRoute? current, IRoute? next); +} +``` + +#### 2. Route Parameters & Query Strings +**Description:** No structured way to pass parameters beyond constructor args. + +**Use Cases:** +- Deep linking +- Bookmarkable routes +- Passing optional parameters + +**Proposed API:** +```csharp +public interface IRoute +{ + string RouteName { get; } + IRouterHost RouterHost { get; } + IReadOnlyDictionary? Parameters { get; } // NEW +} + +// Usage: +router.NavigateTo(new { userId = "123", tab = "settings" }); +``` + +#### 3. Navigation Cancellation +**Description:** No way to cancel in-progress navigation. + +**Use Cases:** +- Cancel navigation if user navigates away quickly +- Cancel if validation fails asynchronously + +**Proposed API:** +```csharp +public sealed class RouteChangingEventArgs(IRoute? previous, IRoute? next) : EventArgs +{ + public IRoute? Previous { get; } = previous; + public IRoute? Next { get; } = next; + public bool Cancel { get; set; } // NEW +} +``` + +#### 4. Async Navigation Support +**Description:** All navigation is synchronous. + +**Use Cases:** +- Load data before navigating +- Async validation +- Async guards/middleware + +**Proposed API:** +```csharp +Task NavigateToAsync() where T : IRoute; +Task NavigateBackAsync(); +``` + +#### 5. Route State/Data Passing +**Description:** No way to pass transient state between routes without constructor parameters. + +**Use Cases:** +- Passing selected item from list to detail view +- Returning results from modal routes +- Wizard-style navigation with accumulated state + +**Proposed API:** +```csharp +router.NavigateTo(state: selectedItem); +``` + +### 🟢 Priority: MEDIUM + +#### 6. Deep Linking Support +**Description:** No URI-based routing or route registration. + +**Use Cases:** +- Restore application state from URL +- External navigation (e.g., from email links) +- Bookmarking specific views + +**Proposed API:** +```csharp +router.RegisterRoute("home"); +router.RegisterRoute("users/{userId}"); +router.NavigateToUri("users/123"); +``` + +#### 7. Route Lifecycle Hooks +**Description:** No hooks for route entry/exit logic. + +**Use Cases:** +- Initialize data when entering route +- Cleanup resources when leaving route +- Track analytics + +**Proposed API:** +```csharp +public interface IRoutable : IRoute +{ + Task OnNavigatedTo(NavigationContext context); + Task OnNavigatedFrom(NavigationContext context); +} +``` + +#### 8. Navigation History Management +**Description:** Basic stack only, no advanced history manipulation. + +**Missing:** +- Clear history +- Remove specific items from stack +- Insert items at specific positions +- History length limits per route type + +#### 9. Logging & Diagnostics +**Description:** No built-in logging or diagnostic information. + +**Needed:** +- Navigation event logging +- Performance metrics +- Error tracking +- Debug mode with detailed traces + +**Proposed:** +```csharp +public interface IRouterLogger +{ + void LogNavigation(IRoute? from, IRoute? to); + void LogNavigationFailed(IRoute? from, IRoute? to, Exception ex); +} +``` + +#### 10. Route Caching Strategies +**Description:** New route instance created on every navigation. + +**Use Cases:** +- Reuse existing route instances +- Preserve scroll position and UI state +- Reduce memory allocations + +**Proposed:** +```csharp +public enum RouteCachingStrategy +{ + AlwaysCreate, // Current behavior + ReuseIfExists, // Cache and reuse + Singleton // Only one instance ever +} +``` + +#### 11. Source Generators for Performance +**Description:** No compile-time code generation for route registration and factory optimization. + +**Current Problem:** +- `RouteFactory` delegate relies on reflection or manual factory implementations +- `ViewLocatorBase.TryDeduceControl()` uses reflection (`Type.GetType`, `Activator.CreateInstance`) +- Route creation has runtime overhead from reflection +- No compile-time validation of route configurations + +**Use Cases:** +- Auto-generate optimized route factory implementations at compile time +- Eliminate reflection overhead in route and view creation +- Generate strongly-typed navigation extension methods +- Create compile-time route validation and diagnostics +- Reduce startup time and memory allocations +- Improve AOT (Ahead-of-Time) compilation compatibility + +**Benefits:** +- **Zero runtime reflection** - All route types known at compile time +- **Type safety** - Compile-time errors for invalid routes or missing views +- **Performance** - 10-100x faster route creation (no `Activator.CreateInstance`) +- **AOT-friendly** - Works with Native AOT compilation +- **Intellisense support** - Better IDE experience with generated code +- **Startup time** - Faster application initialization + +**Real-World Example:** +Similar to [StaticViewLocator](https://github.com/wieslawsoltes/StaticViewLocator) by Wiesław Sołtes, which generates static view resolution code for Avalonia, eliminating reflection from view locators. + +**Proposed API:** + +```csharp +// 1. Mark router for generation +[GeneratedRouter] +public partial class AppRouter : IRouter +{ + // Source generator will implement the factory +} + +// 2. Mark routes for registration +[Route] +public class HomeRoute : IRoute +{ + public HomeRoute(IRouterHost host) { ... } +} + +[Route] +public class UserProfileRoute : IRoute +{ + public UserProfileRoute(IRouterHost host, string userId, int? tab = null) { ... } +} + +// 3. Auto-generated code (example output) +public partial class AppRouter +{ + // Generated static factory dictionary + private static readonly Dictionary> s_routeFactories = new() + { + [typeof(HomeRoute)] = (host, args) => new HomeRoute(host), + [typeof(UserProfileRoute)] = (host, args) => new UserProfileRoute( + host, + (string)args[0], + args.Length > 1 ? (int?)args[1] : null), + }; + + // Generated strongly-typed navigation extensions + public static class Extensions + { + public static HomeRoute NavigateToHome(this IRouter router) + => (HomeRoute)router.NavigateTo(); + + public static UserProfileRoute NavigateToUserProfile( + this IRouter router, + string userId, + int? tab = null) + => (UserProfileRoute)router.NavigateTo(userId, tab); + } +} + +// 4. Usage in application +router.NavigateToUserProfile("user123", tab: 2); // Strongly-typed, no reflection! +``` + +**Generated ViewLocator Enhancement:** + +```csharp +// Mark view locator for generation +[GeneratedViewLocator] +public partial class AppViewLocator : ViewLocatorBase +{ + // Generated view resolution (similar to StaticViewLocator) + private static readonly Dictionary> s_views = new() + { + [typeof(HomeRoute)] = () => new HomeView(), + [typeof(UserProfileRoute)] = () => new UserProfileView(), + }; + + public override Control? ResolveControl(IRoute? route) + { + if (route is null) return null; + + var type = route.GetType(); + return s_views.TryGetValue(type, out var factory) + ? factory() + : null; + } +} +``` + +**Implementation Notes:** +- Use Roslyn IIncrementalSourceGenerator (C# 9.0+) +- Generate partial classes and extension methods +- Support incremental generation for fast builds +- Provide diagnostics for missing routes/views +- Convention-based: `*Route` → `*View` mapping +- Generate XML documentation for generated methods +- Support for nullable reference types +- Compatible with Native AOT compilation + +**Performance Impact:** +- Route creation: ~100x faster (static instantiation vs reflection) +- View resolution: ~10-50x faster (dictionary lookup vs Type.GetType) +- Memory: Lower allocation (no runtime type resolution) +- Startup: Faster (no reflection scanning) +- AOT: Full support (no reflection metadata needed) + +### 🟢 Priority: LOW + +#### 12. Route Transitions/Animations +**Description:** Basic content switching, no transition control. + +**Note:** Avalonia's `TransitioningContentControl` provides some support, but no programmatic control. + +#### 13. Modal/Dialog Route Support +**Description:** No concept of modal vs. page routes. + +**Use Cases:** +- Display route as modal dialog +- Block navigation while modal is active +- Return values from modal routes + +#### 14. Nested Routers +**Description:** No explicit support for nested routing hierarchies. + +**Use Cases:** +- Master-detail layouts with independent navigation +- Tab-based navigation +- Multi-pane applications + +#### 15. Route Templates/Conventions +**Description:** No way to define route naming conventions or patterns. + +--- + +## Missing Documentation + +### 🟡 Priority: HIGH + +#### 1.
