Reactive programming

“In computing, Reactive Programming is Programming paradigm oriented around data-flow and propagation of change.”


Reactive Programming is concurrent programming (running parallel) and high performance.Reactive Programming a gift from Microsoft(C# extensions).

Reactive Programming is a style of micro-architecture involving intelligent routing and consumption of events

The Four Reactive principles

  1. Responsive

  2. Scalable

  3. Resilient(stretched)

  4. Event- Driven (Message-Driven)

“Reactive” is used broadly to define the event-driven system (like UI Update and Network Protocol), and Non-Blocking event-driven architecture.


if we want to build reactive apps, we need two essential building blocks.

  1.  A contract for interop between Non-blocking components(Reactive Stream spec).
  2.  API for composing asynchronous program(Reactive Extension).

Reactive is Domain of Specific programming languages.
