SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill provides a lean, fast library for reactive programming in .NET, allowing developers to work with values that arrive over time, like button clicks, timer ticks, or network replies.

Core Features & Use Cases

  • Reactive Programming: Offers a familiar LINQ-like API for working with observables, signals, and operators.
  • Minimal Runtime Dependencies: Does not rely on System.Reactive, R3, or R3Async, reducing runtime overhead.
  • Ahead-of-Time Compilation: Optimizes for AOT compilation for better performance and less memory allocation.
  • Use Case: Develop responsive UIs that react to user input in real-time, handle streams of data efficiently, and compose complex event-driven workflows.

Quick Start

Add the ReactiveUI.Primitives package to your .NET project and start using the lean, fast reactive programming model with the IObservable<T> and IObserver<T> interfaces.

FAQPage Schema
What is reactive programming in .NET and when do I need it?

Reactive programming in .NET handles asynchronous data streams like button clicks or network replies over time. You need it to develop responsive UIs and compose complex event-driven workflows using familiar LINQ-like operators.

How do I start building reactive pipelines without System.Reactive?

To build reactive pipelines without System.Reactive, add the ReactiveUI.Primitives package to your .NET project and implement the IObservable<T> and IObserver<T> interfaces using its lean, LINQ-like operators.

Does this reactive library support Ahead-of-Time compilation for .NET?

Yes, this reactive library optimizes for Ahead-of-Time (AOT) compilation in .NET, which ensures better performance and reduces memory allocation compared to traditional reactive runtime dependencies.

What's the best way to handle event streams in .NET without heavy dependencies?

The best way to handle event streams without heavy dependencies is using a minimal runtime library that provides LINQ-like operators for observables, avoiding external libraries like System.Reactive or R3Async to reduce overhead.

Why use a minimal reactive library instead of existing .NET reactive frameworks?

Use a minimal reactive library to achieve faster performance and lower memory allocation through AOT compilation, deliberately avoiding the runtime overhead associated with larger frameworks like System.Reactive or R3.
