    core.logic

    core.logic

    A logic programming library for Clojure & ClojureScript

    core.logic brings logic programming to Clojure and ClojureScript through an implementation of miniKanren, enabling relational, constraint-based, and nominal logic programming. It allows complex reasoning and declarative problem-solving directly in Clojure. core.unify provides a la carte unification facilities that are not deeply tied into the operation of a logic engine.

    Workflow

    Workflow

    A Swift and Kotlin library for making composable state machines

    ...A unidirectional data flow library that uses immutable data within each Workflow. Data flows in a single direction from the source to the UI, and events in a single direction from the UI to the business logic. Each logical component area is separated into a Workflow with a finite set of states and the logic to transition between them.

    Stremio

    Stremio - Freedom to Stream

    ...It manages add-on installation and configuration in-app, letting users combine official and community sources without leaving the UI. Playback hooks into the stream types exposed by add-ons and the core’s selection logic, with UI affordances for choosing sources, subtitles, and quality. Because the heavy business logic lives in the core, the web app stays focused on UX, routing, accessibility, localization, and smooth state transitions between pages.

    Middy

    Middy

    The stylish Node.js middleware engine for AWS Lambda

    ...If you have used web frameworks like Express, then you will be familiar with the concepts adopted in Middy and you will be able to get started very quickly. A middleware engine allows you to focus on the strict business logic of your Lambda and then attach additional common elements like authentication, authorization, validation, serialization, etc. in a modular and reusable way by decorating the main business logic. One of the main strengths of serverless and AWS Lambda is that, from a developer perspective, your focus is mostly shifted toward implementing business logic. ...

    getty

    getty

    Asynchronous network I/O library

    ...Within Getty, each connection (session) involves two separate goroutines. One handles the reading of TCP streams, UDP packets, or WebSocket packages, while the other manages the logic processing and writes responses into the network write buffer. If your logic processing might take a considerable amount of time, it's recommended to start a new logic process goroutine yourself within codec.go's (Codec)OnMessage method. Additionally, you can manage heartbeat logic within the (Codec)OnCron method in codec.go. If you're using TCP or UDP, you should send heartbeat packages yourself and then call session.go's (Session)UpdateActive method to update the session's activity timestamp. ...

Projects like this often include a set of components for creating modular AI tasks, connecting data sources, and integrating with APIs so that complex automation can run with minimal boilerplate. Given the broader context of AI workflow tools, FlowlyAI might emphasize extensibility, allowing users to plug in different models or custom logic blocks depending on their specific use cases.

    The "Third Way" for Home Assistant Automations

    CAFE (Complex Automation Flow Editor) for Home Assistant is an innovative automation authoring tool that provides a visual flow editor inside Home Assistant, offering a “third way” between manual YAML and external flow tools by transpiling visual flows directly into native Home Assistant automation YAML. It’s designed to give users the visual clarity of tools like Node-RED without the overhead of a separate execution engine, storing the logic as standard YAML that runs in the core automation engine with zero added resource use. The editor lets users drag and drop nodes to represent triggers, conditions, actions, and variable manipulation, and then compiles those flows into highly readable and native YAML that is fully compatible with Home Assistant. Users can import existing automations to visualize and edit them, and CAFE respects the same underlying data structures so the native automation editor and CAFE can interoperate on the same logic.
