Overview

Leaven is a lightweight component model designed specifically for Clojure and ClojureScript. It acts as a pervasive influence that significantly enhances how applications are structured and managed. This innovative framework modifies traditional component management, allowing developers to create more efficient, modular systems that are easy to start and stop as needed.

With its straightforward syntax and powerful features, Leaven facilitates robust dependency management and seamless integration of components. By allowing for composite components and providing essential lifecycle functions, it transforms how developers approach system design and implementation in functional programming.

Features

Lightweight Design: Leaven's minimalistic approach allows developers to quickly get started with component management without a steep learning curve.
Start and Stop Functions: Provides essential functions for starting and stopping components, ensuring that the updated component is always utilized.
Defsystem Macro: Enables the definition of composite components, specifying sub-components as symbols and managing their lifecycle automatically.
Dependency Management: The :depends option ensures components are aware of their dependencies, which helps maintain system integrity and functionality.
Lifecycle Hooks: The :on-start and :on-stop options let developers define custom functions that are triggered during the component's lifecycle, enhancing control over state transitions.
Protocols for Component Providers: Implements the Startable and Stoppable protocols, providing a standardized way to manage component state and interactions.
Status Functionality: The Queryable protocol offers a status method, allowing components to report their current state, which is crucial for debugging and monitoring.
Async Capability: Includes support for core.async channels, enabling smooth data flow and real-time updates between components.
