Generators.Blazor

Excubo.Generators.Blazor is a performance optimization tool for Blazor applications. It uses source generators to replace reflection-based parameter setting with a faster, compile-time approach, and includes analyzers to detect common pitfalls like missing keys in loops.

Key Features

• SetParametersAsync Source Generator — Replaces the default reflection-based SetParametersAsync method with a generated, type-safe implementation, increasing parameter setting performance up to 6x.
• Missing @key Diagnostic — Analyzes Razor code and warns when loops render elements or components without an @key directive, preventing performance and correctness issues.
• Required Parameters Diagnostic — Provides an experimental feature to mark component parameters as required, either individually or by default, improving API clarity.
• Opt-in/Opt-out Control — Allows enabling the generator globally via _Imports.razor or disabling it per component for flexibility.

Philosophy

The project emphasizes compile-time optimizations over runtime reflection to achieve better performance in Blazor applications, following Microsoft's own performance recommendations.
