Dropzone
Drag'n'drop library, supports image previews and shows progress bars
Dropzone is a TypeScript-based browser library that turns ordinary HTML elements into drag-and-drop file upload interfaces. It handles file selection, previews, progress reporting, and XHR-based uploading with minimal setup. Multiple files can be processed together, and large files can be divided into smaller chunks for more reliable transfer. Image uploads can generate thumbnails and resize images in the browser before transmission. The library also supports Amazon S3 multipart upload workflows. Developers can replace default event handlers and styling to fully customize appearance and behavior. Version 6 ships its own TypeScript definitions and is maintained in a monorepo containing the library, documentation, website, tests, and examples. -

Gifted Form
One React-Native form component to rule them all
React Native Gifted Form is a form-building component library for React Native applications. It provides reusable widgets for text inputs, text areas, selects, switches, dates, countries, modal subforms, hidden values, notices, and submit actions. Validation rules can be attached to individual fields and executed when a form is submitted. Forms with the same name can share stored values through GiftedFormManager. External state management is also supported for selected widgets through controlled values and change callbacks. Google Places integration is available through a dedicated location widget. Developers can create additional widgets by implementing the library’s widget mixin, making the form system extensible beyond its built-in controls. -

Pify
Promisify a callback-style function
Pify is a JavaScript package for converting callback-based functions into promise-returning equivalents. It can promisify a single function or process the methods of an entire module automatically. This makes older Node.js callback APIs easier to use with async and await syntax. Developers can selectively include or exclude methods through names or regular-expression patterns. The library can return multiple callback values as an array when an API provides more than one successful result. It also supports APIs that do not follow the conventional error-first callback pattern. Additional options allow the module's main function to remain untouched and permit use of a custom Promise implementation. -

fastq
Fast, in memory work queue
fastq is a high-performance in-memory work queue for JavaScript and Node.js applications. It runs tasks through a worker function while enforcing a configurable concurrency limit. Both traditional callback workers and Promise-based async workers are supported. Tasks can be added to either the front or back of the queue depending on scheduling needs. Processing can be paused, resumed, emptied, or terminated while exposing the current queue length and idle state. Hooks report conditions such as drain, saturation, empty queues, and task errors. TypeScript definitions are included, and the package is designed to provide queue management with very little performance overhead. -

screenfull
Wrapper for cross-browser usage of the JavaScript Fullscreen API
Screenfull is a lightweight JavaScript library that simplifies use of the browser Fullscreen API across supported browsers. It lets developers place an entire page or an individual element into fullscreen mode through a consistent interface. The library smooths over browser-specific API differences that would otherwise require extra compatibility code. Applications can request fullscreen, exit it, toggle it, inspect the active fullscreen element, and check whether fullscreen is available. It also exposes fullscreen change and error events for reactive interfaces. Screenfull is distributed as an ESM package, is only about 0.7 kB when gzipped, and is considered feature complete. It does not support fullscreen operation on iPhone. -

Marble Skill Taxonomy
Structured taxonomy of what children learn across the primary years
Marble Skill Taxonomy is an open structured dataset that maps what children learn across primary and elementary education. It breaks curriculum content into fine-grained micro-topics instead of leaving learning goals as broad standards. Each topic includes subject, domain, age range, description, evidence criteria, assessment prompt, and stable identifiers. The dataset also defines prerequisite relationships, so developers can trace what a learner should master before a concept. It aligns micro-topics to national curriculum standards such as NGSS, Common Core, and the UK National Curriculum. It is useful for learning platforms, curriculum tools, tutoring systems, assessment products, and education research projects. -

big.js
Fast JavaScript library for arbitrary-precision decimal arithmetic
big.js is a compact JavaScript library for arbitrary-precision decimal arithmetic. It avoids many floating-point accuracy problems that occur with JavaScript’s native Number type. Values are stored using a decimal coefficient, exponent, and sign rather than ordinary binary floating-point representation. Its API supports arithmetic, comparisons, powers, square roots, rounding, and common numeric formatting methods. Precision and rounding behavior can be configured for operations such as division. The library has no runtime dependencies and is only about 6 KB when minified. It supports browsers, Node.js, ES modules, CommonJS, and other JavaScript environments while keeping the API deliberately smaller than bignumber.js or decimal.js. -

Deoptigate
Investigates v8/Node.js function deoptimizations
Deoptigate is a Node.js performance-analysis tool for investigating V8 function optimizations and deoptimizations. It can run a Node.js application with the necessary V8 logging enabled or analyze existing V8 log files. Results are presented through an interactive browser interface rather than raw diagnostic output. The report summarizes optimizations, deoptimizations, and inline cache activity for each source file. Source code is annotated with severity-based markers that highlight potential performance problems. Selecting a marker reveals more detailed information about the corresponding V8 event. It is intended for developers diagnosing JavaScript performance issues caused by V8's speculative optimization behavior. -

Pokedex.org
Offline-capable Pokédex web site
Pokedex is an offline-capable Pokémon encyclopedia built as a fully client-side JavaScript web application. It uses Service Workers to cache application resources so the Pokédex remains usable without a network connection. PouchDB provides browser-side data storage, while Web Workers move heavier processing away from the main interface thread. The UI is rendered with virtual-dom to keep interactions responsive on desktop and mobile devices. Pokémon data can be generated from PokéAPI and packaged into local database resources used by the application. The repository includes development, build, testing, and Service Worker versioning workflows. The project is now unmaintained but remains a notable example of an offline-first progressive web application architecture. -

Q
A promise library for JavaScript
Q is a JavaScript promise library created before native promises became standard across modern browsers and Node.js. It lets asynchronous functions return promise objects representing future values or errors instead of relying entirely on nested callbacks. Promise chains flatten asynchronous control flow and automatically propagate failures toward shared error handlers. The library provides deferred objects, combinators, delays, timeouts, callback adapters, and utilities for composing asynchronous operations. It can interoperate with promise implementations from libraries such as jQuery, Dojo, When.js, and WinJS. Q was distributed for browsers, CommonJS, AMD, Bower, and other historical JavaScript environments. The repository is now archived, and its maintainers recommend native JavaScript promises for new development. -

Style2Paints
Sketch + style = paints
style2paints is an AI-assisted colorization system aimed primarily at line art and manga, turning monochrome drawings into colored illustrations with minimal manual effort. It combines automatic color inference with user guidance, letting artists nudge the model using sparse color hints, masks, or style references. The pipeline focuses on preserving line quality while spreading coherent colors and shading across regions that are often ambiguous to purely automatic methods. Iterative refinement is a core workflow: you can add or adjust hints, rerun inference, and progressively converge on a desired palette and lighting. Beyond flat fills, the model attempts plausible shading and highlights so the result feels less like a “paint bucket” and more like a finished illustration. Because it’s built for artists rather than only researchers, the project emphasizes an approachable UI, predictable edits, and reproducible outputs across sessions. -

Zip.js
JavaScript library to zip and unzip files
Zip.js is a JavaScript library for creating, reading, and editing ZIP files directly in the browser or in Node.js environments, supporting various compression methods and encryption. -
19
Zoomerang.js
Drop in zoom anything
Zoomerang.js is a lightweight JavaScript library for adding smooth click-to-zoom behavior to almost any element on a web page. Developers attach it to elements with a simple selector-based API and the library handles the visual transition automatically. Images, text, buttons, and other HTML elements can be enlarged while preserving their appearance. Clicking outside the enlarged content or invoking the API restores the original layout. Configuration options control animation duration, background color, padding, and maximum dimensions. Events and programmatic methods allow applications to coordinate custom behavior with zoom transitions. The library has no framework dependency and was distributed through npm, Bower, Component, or a direct script include. -

edgetunnel
edgetunnel 2.0 VLESS/Trojan
edgetunnel is a modified version of a serverless tunnelling solution designed to run on platforms like Cloudflare Workers and Pages, enabling protocols such as VLESS and Trojan to be exposed through edge-functions rather than traditional servers. The project’s fork by cmliu emphasizes conversion of protocol configuration (especially VLESS) into subscription links, so that users can deploy and then generate “Clash” or “Sing-box” compatible subscription content easily. It provides a streamlined way to host proxy endpoints without managing a full server stack, instead leveraging the edge network of Cloudflare for distribution and potential performance. Because it runs at the edge, latency can be minimized and deployment complexity simplified; users supply configuration variables (host, port, UUID, path) and the script handles mapping to technical protocols and subscription formatting. -
21
JsAction
JsAction is a small event delegation library
JSAction is a JavaScript framework developed by Google that provides a structured, event-driven architecture for managing user interactions in large-scale web applications. It simplifies event handling by declaratively binding actions to DOM elements through HTML attributes, enabling clean separation between markup and behavior. JSAction helps improve performance, maintainability, and reliability by minimizing the use of inline scripts and global event listeners. It is especially useful in complex front-end environments where efficient event delegation and well-defined interaction flows are crucial. -
22
TailAdmin
Free and Open-source Tailwind CSS Dashboard Admin Template
TailAdmin is a free and open source admin dashboard template built with Tailwind CSS, designed to help developers quickly create data-driven web applications and backend interfaces. It provides a complete starting point for dashboards, including prebuilt pages, layouts, and UI components that are commonly required in admin panels and control systems. The template is built using a combination of HTML, Tailwind CSS, Alpine.js, and modern build tools, making it lightweight while still offering interactive functionality. TailAdmin includes essential features such as charts, tables, authentication forms, and navigation components, enabling developers to assemble full dashboards without starting from scratch. It also supports multiple frameworks, including React, Next.js, Vue, Angular, and Laravel, making it highly adaptable to different development stacks. With responsive design and dark mode support built in, it ensures usability across devices and environments. -

Earth Engine API
Python and JavaScript bindings for calling the Earth Engine API
The Earth Engine API provides Python and JavaScript client libraries for Google Earth Engine, a planetary-scale geospatial analysis platform. With it, users compose lazy, server-side computations over massive catalogs of satellite imagery and vector datasets without handling raw files locally. The API exposes functional operators for map algebra, reducers, joins, and machine learning that scale transparently on Earth Engine’s backend. Developers authenticate once, work interactively in notebooks or the Code Editor, and export results to Cloud Storage, Drive, or asset collections. Visualization helpers render tiled layers and charts so analysts can iterate quickly on workflows like land-cover mapping, change detection, or time-series analysis. By combining petabyte-scale data with concise functional transforms, the API turns complex remote-sensing pipelines into reproducible scripts that are easy to share. -
24
LIEF
LIEF - Library to Instrument Executable Formats (C++, Python, Rust)
LIEF (Library to Instrument Executable Formats) is a cross-platform library that enables parsing, modifying, and abstracting executable formats such as ELF, PE, and Mach-O. It's widely used in reverse engineering and binary analysis. -

React Hot Boilerplate
Minimal live-editing example for React
React Hot Boilerplate is a minimal historical example demonstrating live editing of React components during development. It was created to show how React Hot Loader could update component code without forcing a full browser refresh. Webpack provides bundling and development-server support, while Babel handles JavaScript transformation. Source changes are pushed into the running application so developers can immediately see updated behavior. The repository intentionally stays small so the hot-reloading configuration is easy to inspect and learn from. It helped popularize state-preserving React development workflows before modern Fast Refresh tooling became standard. The project is now deprecated, and its README directs developers to React Refresh Webpack Plugin instead.
