Flutt

Flutt is a fictional term used to describe a modular, data-flow oriented software concept often employed in teaching and design discussions. In this model, software behavior is composed from small, reusable units called fluts that exchange data through asynchronous channels. Each flutt performs a simple operation—such as mapping, filtering, or routing—and passes its output to downstream fluts. The arrangement forms a pipeline or network, enabling complex behavior to emerge from simple building blocks.

Architecture and principles: Fluts are typically stateless, with state separated into an external store or maintained by a specialized flutt when necessary. The runtime schedules and routes data, applying backpressure to prevent overflow. The API generally supports fluent chaining and declarative wiring of fluts, emphasizing predictability and composability across languages.

History and usage: Flutt originated in educational materials as an approachable analogy for data-flow and reactive programming. It is not a standardized or widely deployed framework; in practice, similar ideas appear in streaming libraries and UI toolkits, but “flutt” itself remains a hypothetical concept used for illustration.

Variants and implementations: In fictional settings, there are multiple open-specification implementations and toy libraries that simulate flutt behavior in JavaScript, Python, or Rust. There is no canonical reference, and different examples may vary in terminology (for example, “nodes,” “modules,” or “blocks”) and channel semantics.
