    RxDart

    RxDart

    The Reactive Extensions for Dart

    RxDart is a reactive programming toolkit that augments Dart’s native Streams with a rich set of Rx-style operators and subjects. It offers composition primitives like map, where, debounce, throttle, merge, combineLatest, and switchMap, enabling expressive pipelines for events and async data. Subjects provide multicast behaviors so multiple listeners can share a single data source while maintaining semantics like replaying the latest value. By emphasizing immutability and one-way data flow,...

    Making multi-player gamedev simpler since 2017

    Making multi-player game dev simpler since 2017. Single-header cross-platform world replication in pure C99. librg is a lightweight library that serves as a middleware between data-transferring libraries (networking, file-streaming, etc.) and core application/game logic. The library was born to solve the complexities of setting up and managing the flow of multi-player games and dedicated game servers. It came a long way in stripping out things that were non-essential, slowly sculpting into...

    py2many

    py2many

    Transpiler of Python to many other languages

    Python is popular, and easy to program in, but it has poor runtime performance. We can fix that by transpiring a subset of the language into a more performant, statically typed language. A second benefit is security. Writing security-sensitive code in a low-level language like C is error-prone and could lead to privilege escalation. Specialized languages such as wuffs exist to address this use case. py2many can be a more general-purpose solution to the problem where you can verify the source...

    Vacuum cleaner card for Home Assistant Lovelace UI

    Vacuum Card is a custom UI component for Home Assistant (specifically its Lovelace dashboard) that provides a user-friendly control panel for robot vacuum cleaners — something the default Home Assistant UI doesn’t supply by default. With vacuum-card installed, users get a visual card on their dashboard showing the vacuum’s state (e.g. cleaning, docked, battery level) and controls to start, stop, pause, or send the robot back to dock, directly from their Home Assistant interface. The card...

    Official React.js wrapper for fullPage.js

    react-fullpage is the official React wrapper for fullPage.js, providing a component that brings full-screen, section-by-section scrolling layouts into React applications. The wrapper uses a render-prop API, where you pass a render function that receives component state and the fullpageApi, allowing you to build React JSX markup while delegating scroll behavior to fullPage.js under the hood. It is distributed in multiple formats, including a standard ES module and a UMD bundle, so it can be...

    Nano Events

    Simple and tiny (107 bytes) event emitter library for JavaScript

    Nano Events is a minimalistic, high-performance event emitter library for JavaScript. Its goal is to provide the simplest possible API to add pub/sub capabilities (emitters and listeners) to any JS object or application, while keeping overhead and bundle size extremely small. Rather than offering many complex features, nanoevents focuses on the core primitives: creating an emitter, subscribing to named events, emitting events with arbitrary data, and unsubscribing. Because of its minimal API...

    safe and easy casting from one type to another in Go

    Cast is a Go library that provides easy and safe conversion (casting) between different types in Go programs. Especially when dealing with interface{} or dynamic/reflect-heavy code, it becomes cumbersome to assert types or convert values reliably; cast addresses that by offering a suite of functions to convert from any input to the target type with predictable behaviour. Rather than relying purely on raw type assertions, it offers ToInt, ToString, ToBool, ToTime, etc., and their...
