BlazorDelta 0.1.1

BlazorDelta

High-performance Blazor components with source generation

⚡ Performance Improvements

• 3-4x faster parameter assignment than ComponentBase
• Near-zero memory allocation (464B → 0B for attribute splatting)
• Automatic CSS optimization with smart change detection
• Parameter change handlers without reflection overhead

🚀 Benchmark Results

📦 Installation

dotnet add package BlazorDelta

Usage

1. Create a component that inherits from DeltaBaseComponent:

public partial class MyComponent : DeltaBaseComponent
{
    [Parameter] public string Title { get; set; }
    [Parameter] public int Count { get; set; }
    
    // Your component logic here
}

2. Build your project - the source generator will automatically create optimized partial methods for your component.

3. Your component now has enhanced delta functionality with automatically generated methods!

How It Works

BlazorDelta uses source generators to analyze your components that inherit from DeltaBaseComponent and automatically generates:

• Optimized state change detection methods
• Delta comparison utilities
• Performance-enhanced rendering logic

All generated code is created as partial class extensions, so your original component code remains clean and focused.

Features

• ✅ Automatic source generation at compile time
• ✅ Performance optimizations for Blazor components
• ✅ Seamless integration with existing Blazor projects
• ✅ Type-safe generated code
• ✅ Zero runtime dependencies for the generator
• ✅ Full IntelliSense support for generated methods

Requirements

• .NET 9.0 or later
• Blazor Server or Blazor WebAssembly project

Example

// Your component
public partial class CounterComponent : DeltaBaseComponent
{
    [Parameter] public int CurrentCount { get; set; }
    [Parameter] public string Label { get; set; } = "Counter";

    private void IncrementCount()
    {
        CurrentCount++;
        // Generated delta methods automatically handle optimized updates
    }
}

The source generator will create additional methods and optimizations automatically when you build.
