Cyclejs
Cycle.js is a functional reactive web framework and observable-driven UI library used for building web applications. It employs a reactive stream architecture that treats the document object model and side effects as continuous data streams, coordinating state and logic through a functional cycle.
The framework distinguishes itself by isolating side effects from core logic using a system of drivers. This architecture maps external events to internal commands through a symmetric input-output pipeline, ensuring that the application remains a cycle of pure functions.
The project provides capabilities for managing asynchronous state, handling browser history, and coordinating animations. It includes tools for verifying time-dependent logic and asynchronous behavior using virtual time and marble diagrams.
Features
- Dataflow Frameworks - Models the entire application as a continuous loop where inputs and outputs are treated as infinite sequences of events.
- Functional Reactive Programming Frameworks - Implements a framework that combines functional programming patterns with reactive data streams for state management.
- Reactive Web Frameworks - Provides a framework focused on reactive data binding and asynchronous web development.
- Cycle-Based State Management - Uses a functional cycle architecture to ensure predictable user interfaces and testable asynchronous logic.
- Circular Dataflow Loops - Implements a self-sustaining reactive loop by connecting application output sinks back to input sources.
- Observable State Management - Uses reactive streams to propagate state changes and event triggers throughout the system without manual subscriptions.
- Reactive State Management - Coordinates data flow and side effects using a reactive cycle to maintain a consistent application state.
- Reactive Stream Architectures - Employs an architecture that isolates side effects from core logic by coordinating data flow through a continuous cycle.
- Side Effect Handlers - Isolates pure logic from impure environment interactions by delegating all external API calls to dedicated driver modules.
- Symmetric Input-Output Mappings - Maps streams of external events to internal commands through a consistent functional transformation pipeline.
- Side Effect Isolation - Separates asynchronous operations and external interactions from core logic to ensure code is predictable and testable.
- Reactive UI Libraries - Provides a library where user interactions and environment changes are handled as continuous reactive streams.
- Functional Cycle Architectures - Manages state and side effects using a functional cycle to keep the user interface predictable.
- Browser DOM Interaction - Renders the user interface and listens for events by treating the document object model as a stream.
