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. The result is safer UI interactions and services that don’t keep doing work the user no longer needs. -

Chart.xkcd
xkcd styled chart lib
Chart.xkcd is a chart library plots “sketchy”, “cartoony” or “hand-drawn” styled charts. It’s easy to get started with chart.xkcd. All that’s required is the script included in your page along with a single <svg> node to render the chart. You can install chart.xkcd via script tag in HTML or via npm. Line chart displays series of data points in the form of lines. It can be used to show trend data, or comparison of different data sets. XY chart is used to plot points by specifying their XY coordinates. A bar chart provides a way of showing data values represented as vertical bars. A stacked bar chart provides a way of showing data values represented as vertical bars. Display labels near every line (default false). Customize tick numbers you want to see on the main line. You can change size of the dots if you want. -

Chartist.js
Simple responsive charts
You may think that this is just yet an other charting library. But Chartist.js is the product of a community that was disappointed about the abilities provided by other charting libraries. Of course there are hundreds of other great charting libraries but after using them there were always tweaks you would have wished for that were not included. Are you planning to use Chartist to create a nice Dashboard or Admin UI? Don't loose any time and kickstart your development using the awesome templates by Creative Tim. They include Chartist and come with awesome chart styles! Specifying the style of your chart in CSS is not only cleaner but also enables you to use awesome CSS animations and transitions to be applied to your SVG elements! Note that CSS3 animations on SVG CSS attributes are not supported on all browsers and the appearance may vary. -

Chinese Poetry
The most comprehensive database of Chinese poetry
This repository is a curated collection of Chinese poems and poets organized into catalogs, metadata, and text representations suitable for research, creative and cultural use. It includes major dynastic corpora, such as Tang and Song poems, as well as biographical and categorization data. Each poem entry is structured with fields like author, dynasty, title, content, and sometimes annotations or alternate versions. Developers and scholars can build tools that query by author, era, keyword, or poetic form using the standardized data structure. Because the project is open, contributors improve metadata, correct text variants, and maintain consistency across classical collections. The corpus enables digital humanities, poetry apps, styling tools, and creative projects that intermix poems with translation, visualization, or musical settings. -

Chokidar
Minimal and efficient cross-platform file watching library
Chokidar is a solution for all the users of Node.js fs.watch who are tired of it not reporting filenames on MacOS and events at all when using editors like Sublime on MacOS. Node.js fs.watch often reports events twice, emits most changes as rename, and it does not provide an easy way to recursively watch file trees nor supports recursive watching on Linux. Same as with Node.js fs.watchFile. Therefore, Chokidar resolves these problems. Initially made for Brunch (an ultra-swift web app build tool), it is now used in Microsoft's Visual Studio Code, gulp, karma, PM2, browserify, webpack, BrowserSync, and many others. It has proven itself in production environments. Chokidar does still rely on the Node.js core fs module, but when using fs.watch and fs.watchFile for watching, it normalizes the events it receives, often checking for truth by getting file stats and/or dir contents. -

ChromeAppHeroes
Chinese manual for excellent Chrome plug-ins
ChromeAppHeroes appears to be a repository with sample or template Chrome apps/extensions — perhaps intended to help developers learn how to build Chrome applications, quick prototypes, or small utilities. As such, it likely includes boilerplate code, manifest definitions, example UI components, and sample functionality (e.g. browser-action buttons, content scripts, background scripts) to illustrate how to structure a Chrome app. For learners or developers new to Chrome extension/app development, ChromeAppHeroes could serve as a starting kit: instead of starting from scratch, they can clone or fork the repo and immediately begin building features, thereby speeding up development. The repository’s open-source nature means users are free to adapt, extend, or repurpose the sample apps to their own needs — for example, privacy tools, quick productivity extensions, or custom browser tooling. -

Classnames
A simple javascript utility for conditionally joining classNames
Classnames is a minimal JavaScript utility that helps you construct CSS class strings based on conditional logic. Instead of manually concatenating strings, developers can pass any combination of strings, arrays, or objects, and the library will output a clean, space-separated class list. When you provide an object, the keys represent class names and the boolean values determine whether each class should be included in the final string. This reduces boilerplate and the risk of typos or stray spaces, especially in React, Vue, or other component-based UIs where dynamic styling is common. The utility is small and framework-agnostic, so it can be used in Node, browser code, or any bundler setup including Browserify and Webpack. It maintains backwards compatibility while evolving (for example, introducing polyfill requirements for older browsers in newer versions), and it ships with TypeScript bindings for better type safety. -

Closure Library
Google's common JavaScript library
The Closure Library is a broad, well-tested, modular, and cross-browser JavaScript library. You can pull just what you need from a large set of reusable UI widgets and controls, and from lower-level utilities for DOM manipulation, server communication, animation, data structures, unit testing, rich-text editing, and more. The Closure Library is server-agnostic and is intended for use with the Closure Compiler. The Closure Library serves as the base JavaScript library for many Google products. Now that the Closure Library is open source, more and more developers outside Google are integrating the library in their own projects. If you are developing a large or growing application, you may benefit from the Closure Library's breadth. A well-tested library can insulate you from cross-browser compatibility issues and the minutiae of client-side programming, letting you focus on the fun stuff. -

ConvNetJS
Deep learning in Javascript to train convolutional neural networks
ConvNetJS is a Javascript library for training Deep Learning models (Neural Networks) entirely in your browser. Open a tab and you're training. No software requirements, no compilers, no installations, no GPUs, no sweat. ConvNetJS is an implementation of Neural networks, together with nice browser-based demos. It currently supports common Neural Network modules (fully connected layers, non-linearities), classification (SVM/Softmax) and Regression (L2) cost functions, ability to specify and train Convolutional Networks that process images, and experimental Reinforcement Learning modules, based on Deep Q Learning. The library allows you to formulate and solve Neural Networks in Javascript. If you would like to add features to the library, you will have to change the code in src/ and then compile the library into the build/ directory. The compilation script simply concatenates files in src/ and then minifies the result. -

Countable
Add live paragraph-, word- and character-counting to an HTML element
Countable is a JavaScript function to add live paragraph-, word- and character-counting to an HTML element. Countable is a zero-dependency library and comes in at 1KB when minified and gzipped. Countable is available as a Node / CommonJS module, an AMD module and as a global. All methods are accessed on the Countable object directly. The on and count methods both accept a callback. The given callback is then called whenever needed with a single parameter that carries all the relevant data. this is bound to the current element. -

Crossfilter
Fast n-dimensional filtering and grouping of records
Crossfilter is a JavaScript library for exploring large multivariate datasets in the browser. Crossfilter supports extremely fast (<30ms) interaction with coordinated views, even with datasets containing a million or more records; we built it to power analytics for Square Register, allowing merchants to slice and dice their payment history fluidly. Since most interactions only involve a single dimension, and then only small adjustments are made to the filter values, incremental filtering and reducing is significantly faster than starting from scratch. Crossfilter uses sorted indexes (and a few bit-twiddling hacks) to make this possible, dramatically increasing the performance of live histograms and top-K lists. Crossfilter is available under the Apache License. -

CyC2018.github.io
Personal knowledge site built with GitHub Pages
This is a personal knowledge site built with GitHub Pages, organizing computer science notes and study materials in a browsable format. It aggregates content across algorithms, data structures, networking, operating systems, databases, and interview preparation into a coherent index. The presentation emphasizes succinct explanations paired with diagrams, tables, or code snippets to speed recall. Because the site is generated from a repository, it benefits from issue tracking, pull requests, and version history, making it easy to update and maintain. The structure encourages incremental learning: you can dip into a topic, follow internal links, and return later with a clear sense of progress. It doubles as both a study guide for learners and a quick reference for practitioners revisiting fundamentals. -

Small, fast, and modular DOM and event library for modern browsers
Small, fast, and modular DOM and event library for modern browsers. Same familiar API as jQuery (but without the extra "weight" of modules like $.ajax, $.animate, and $.Deferred). Dependency-free. Weighs in at only 1KB to 12KB (minified), depending on the included modules. The full bundle is about 4KB gzipped. DOMtastic also serves as a starting point for your own application-specific DOM API (read more). Rollup and babel are used to create a UMD bundle (supporting AMD, CommonJS, and fallback to browser global). -

Device Motion Gesture for JavaScript
JavaScript library for recording and recognising device gestures.
A JavaScript library for detecting gestures made by the user whilst holding their mobile device. The software converts the continual stream of motion readings into distinct gesture events. All you need to do is attach event-handlers to the gestures. Your functions get called when the user makes the gesture with the device. The library comes with some pre-recorded gestures. You can also record your own custom gestures using the recorder application. NOTE: This library recognises gestures made by moving the hand-held device in your hand. It does not recognise gestures from video or images. -

Dragula
Drag and drop so simple it hurts
Dragula is a lightweight JavaScript library that makes drag-and-drop between containers in the browser extremely simple. You provide one or more container elements and it handles all the DOM event wiring so users can drag items within and between containers with natural behavior. By default, any element in those containers can be picked up and dropped in any other container in the group, with sensible rules for what happens if the item is dropped elsewhere. The library includes configuration hooks for customizing what counts as a valid container, whether items are movable, where they can be dropped, and how they behave when “spilled” outside of containers. It works across modern browsers and even older ones, focusing on minimal dependencies and a straightforward API. The included CSS gives you a basic visual style for dragged items and placeholder states, while still being easy to override with your own styles. -

Dumper.js
A better and pretty variable inspector for your Node.js applications
Dumper.js is a small JavaScript utility for pretty-printing or serializing JavaScript objects and data structures in a human-readable, tree-like format — useful for debugging, logging, or inspecting complex nested data. When you pass an object (or array, or nested structure) through dumper.js, it outputs a representation that shows keys, nested depth, and structure clearly, making it easier to understand what’s inside compared to default JSON dumps or console.log clutter. This can be especially helpful when dealing with large objects, deeply nested responses, or when you need to inspect something quickly without building custom serializers. The utility is minimal and straightforward: you import it, pass your data, and get the result. Because it doesn’t rely on heavy dependencies, it can be easily included in small scripts or bigger projects alike.
