JavaScript & Node.js Testing
Comprehensive and exhaustive JavaScript & Node.js testing
...It distinguishes between different kinds of tests—unit, integration, end-to-end—and shows when each is appropriate given time and risk constraints. The guide focuses on removing flakiness by isolating side effects, controlling randomness, and stabilizing async code paths. It also demonstrates test design techniques like arranging test data, using expressive assertions, and structuring test suites for readability and discoverability. Tooling agnosticism is a theme: patterns are illustrated with popular tools but written to survive framework churn. ... -

React Projects
Collection of React example / tutorial projects
This repository is a collection of small-to-medium React applications that showcase practical patterns, from stateful widgets to multi-page interfaces. Each project is self-contained and demonstrates specific techniques—hooks for state and effects, context for global state, custom hooks for reuse, and reducer patterns for complex updates. The codebases include common UI tasks like forms, modals, lists, filtered search, and pagination, along with data fetching and basic routing where appropriate. Because every project focuses on a narrow set of concepts, learners can clone a single folder, run it, and grasp the idea without wading through a monolith. ... -

Kitten
A statically typed concatenative systems programming language
...Programs are composed by chaining small words that transform a typed stack, and the compiler uses type inference to ensure compositions are valid. The language explores disciplined handling of side effects, aiming to separate pure transformations from operations that perform I/O or mutate state. Its design encourages small, reusable building blocks that compose cleanly, while still permitting low-level control where performance matters. The implementation targets efficient compiled code and investigates how advanced type systems can improve reliability in a stack-based language. ... -

Polysemy
Higher-order, no-boilerplate monads
Polysemy is a high-performance, zero-boilerplate effect system for Haskell, designed to simplify the handling of side effects in functional programs. Unlike traditional monad transformer stacks, Polysemy uses a modern approach based on freer monads and interpreters, allowing developers to define, compose, and interpret effects in a more modular and testable way. It aims to offer both flexibility and performance without sacrificing type safety or expressiveness. -

JavaScript and React Patterns
Repo related to the FrontendMasters course on JavaScript and React
JavaScript and React Patterns showcases idiomatic patterns and anti-patterns for building React applications, focusing on readability, performance, and maintainability. It translates fuzzy best practices into concrete examples—how to compose components cleanly, manage state thoughtfully, and avoid foot-guns with effects and memoization. The guidance leans on modern React paradigms like hooks, context, custom hooks, and component composition to replace older, heavier patterns. Performance considerations appear throughout, such as when to memoize, how to minimize re-renders, and where to split components. Each example is concise and focused, making it easy to apply to real codebases without wading through long essays. ... -

Cancelable Async Flows
Cancelable Async Flows (CAF)
CAF (Cancelable Async Flows) is a small utility that brings cooperative cancellation to JavaScript async workflows. It wraps async generators or promise-returning functions so they can respond to a cancel signal and halt work early, preventing wasted CPU and stray side effects. The library encourages a disciplined pattern: pass a token into your task, periodically check it, and unwind gracefully when cancellation is requested. This approach avoids brittle timeouts and “fire-and-forget” leaks by making cancellation a first-class concern. CAF is framework-agnostic and pairs well with fetch, timers, or custom async primitives, giving you a consistent contract for stopping in-flight operations. ... -

React Beautiful DnD
Beautiful and accessible drag and drop for lists with React
...It supports common patterns like reordering within a list, moving items between multiple lists, and integrating with virtualized lists. Clear lifecycle callbacks expose what changed during a drag so you can persist updates or trigger side effects reliably. -

Flutter Hooks
React hooks for Flutter
flutter_hooks extends Flutter with a hooks system inspired by React Hooks, aiming to simplify stateful logic inside widgets. It allows developers to reuse and isolate stateful behaviors like animations, controllers, and subscriptions without writing boilerplate StatefulWidgets. Common hooks like useState, useEffect, and useMemoized provide clear ways to manage lifecycle and dependencies inside a widget’s build method. The library improves code readability by keeping logic close to the UI... -

Harmonica
A simple, physics-based animation library
...The project includes spring animation behavior that can make interface movement feel more organic than fixed linear transitions. It also includes projectile-style simulation that is useful for particles, motion effects, and game-like interactions. Harmonica can be used with terminal interfaces, Bubble Tea applications, and graphical projects that need realistic movement. Its main value is giving Go developers a small, efficient way to add physically inspired animation without building the math from scratch. -

glfx.js
An image effects library for JavaScript using WebGL
glfx.js is a JavaScript image-effects library that uses WebGL to apply real-time filters and transformations directly in the browser. It exposes a simple API where images are uploaded into GPU textures, processed with shader-based filters, and rendered to a WebGL canvas. Because the work is done on the GPU, many effects that would be too slow in pure JavaScript (like complex blurs, lens effects, or tilt-shift) can run interactively, even on large images. -

Superfine
Absolutely minimal view layer for building web interfaces
Superfine is a minimal view layer for building web interfaces. Think Hyperapp without the framework—no state machines, effects, or subscriptions, just the absolute bare minimum (1 kB minified+gzipped). Mix it with your favorite state management library or use it standalone for maximum flexibility. When describing how a page looks in Superfine, we don't write markup. Instead, we use the h() and text() functions to create a lightweight representation of the DOM (or virtual DOM for short), and patch() to actually render the DOM. ... -

lax.js
Library to create smooth & beautiful animations when you scroll
...The easiest way to get started is to use presets via html classes. Multiple presets can be chained together and they can be customised to suit your needs. Use the preset explorer to explore effects and see a simple example here. To increase performance, lax.js indexes the list of elements to animate when the page loads. If you're using a library like React, Vue or EmberJS, it is likely that you are adding elements after the initial window.onload. Because of this you will need to call lax.addElements when you add components to the DOM that you want to animate. -

BlurKit
The missing Android blurring library
The missing Android blurring library. Fast blur-behind layout that parallels iOS. BlurKit is an extraordinarily easy-to-use and performant utility to render real-time blur effects in Android. BlurKit is faster than other blurring libraries due to a number of bitmap retrieval and drawing optimizations. We've been logging benchmarks for the basic high-intensity tasks for a 300dp x 100dp BlurView. -

concordia
Powerful search library, best suited for computer-aided translation
...It uses a RAM stored index, which takes up approximately 600MB of memory for a corpus of 2 million sentences. It is based on the idea of a suffix array, enhanced by the presence of other auxiliary data structures. The effects are stunning - Concordia is able to do simple substring lookup at the pace of 5000 queries per second (on personal PC) - a speed which can not be achieved by any other search library. Moreover, Concordia can perform its own "concordia search". For a given input sentece, all substring matches covering this sentence are retrieved. ... -

Animate on scroll library
AOS is a lightweight JavaScript and CSS library for animating elements as users scroll through a webpage. It lets developers add animation behavior directly through HTML data attributes, making it easy to apply effects without writing custom JavaScript for every element. The library supports animations that trigger while scrolling down and can reset when scrolling back up. It includes options for duration, delay, easing, offsets, anchors, and once-only animation behavior.
