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. -

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. ... -

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. -

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. ... -

lsfg-vk
Lossless Scaling Frame Generation on Linux
...Instead of relying on driver-specific or hardware-accelerated upscaling, this layer intercepts Vulkan API calls and injects frame interpolation on the fly, effectively producing smoother motion in supported games and applications by creating synthetic intermediate frames. It is structured as a modular codebase with separate components for the backend, configuration UI, CLI tooling, shared logic, and the core layer implementation. Although it targets Linux environments and handhelds like Steam Deck, it depends on an existing installation of Lossless Scaling on the system to provide its frame generation logic. -
