analytics.js boilerplate
Examples and best practices for using analytics.js
analyticsjs-boilerplate is a reference implementation for using Google Analytics analytics.js on modern websites. It collects best practices for tracking page views, user interactions, errors, performance metrics, and custom events in a structured way. The project was created to help developers avoid scattered analytics snippets and instead start from a cleaner, more maintainable setup. It includes patterns for organizing analytics logic, reporting useful metrics, and making implementation decisions more deliberate. While analytics.js itself is now a legacy Google Analytics library, the repository remains useful as a historical and educational reference for analytics architecture. Its main value is showing how to treat analytics as a thoughtful engineering layer rather than a pile of ad hoc tags. -

asynquence
Asynchronous flow control
asynquence is a small, promise-like flow library for composing asynchronous steps into readable sequences. Instead of juggling nested callbacks, you create a chain of operations that pass values forward and route errors consistently. It supports concurrency control via “gates” and “races,” letting multiple tasks proceed and rejoin at the right moment without complex bookkeeping. The design emphasizes clarity and debuggability, keeping stack traces and error paths straightforward. Plugins expand the core with helpers for iteration, mapping, timeouts, and integration with event sources, so you can grow from simple sequences to richer workflows. Even though modern Promises and async/await exist, asynquence remains a compact, educational model for structuring async code with explicit, composable semantics. -

babel-plugin-macros
Allows you to build simple compile-time libraries
Currently, each babel plugin in the babel ecosystem requires that you configure it individually. This is fine for things like language features but can be a frustrating overhead for libraries that allow for compile-time code transformation as an optimization. babel-plugin-macros defines a standard interface for libraries that want to use compile-time code transformation without requiring the user to add a babel plugin to their build system (other than babel-plugin-macros, which is ideally already in place). There is cpu usage/time overhead; the client needs to run the code to generate these classes every time the page loads. There is code bundle size overhead; the client needs to receive a CSS parser in order to generate these class names, and shipping this makes the amount of js the client needs to parse larger. Eval-ing out code at compile time that will be baked into the runtime code, for instance, to get a list of directories in the filesystem. -

bignumber.js
A JavaScript library for arbitrary-precision decimal arithmetic
bignumber.js is a JavaScript library for arbitrary-precision decimal and non-decimal arithmetic. Faster, smaller, and perhaps easier to use than JavaScript versions of Java's BigDecimal. Replicates the toExponential, toFixed, toPrecision and toString methods of JavaScript's Number type. Includes a toFraction and a correctly-rounded squareRoot method. Supports cryptographically secure pseudo-random number generation. Wide platform compatibility, uses JavaScript 1.5 (ECMAScript 3) features only. If a smaller and simpler library is required see big.js. It's less than half the size but only works with decimal numbers and only has half the methods. It also has fewer configuration options than this library, and does not allow NaN or Infinity. See also decimal.js, which among other things adds support for non-integer powers, and performs all operations to a specified number of significant digits. -

board2D.js
A JavaScript game library to quickly develop board games for the web
Board2D.js is a JavaScript library that allows you to quickly develop 2D board games for the web. It is extremely easy to use and contains a very rich API. Download the ZIP, and extract it to a folder. Inside it, the "lib" folder contains the javascript library file. You can include it in your projects as-is. For an example of how to use the library, you can find two mini samples of tic-tac-toe and chess in the examples directory. There is no API manual currently, but if you use an editor like Brackets, it will show you the list of functions. Just do not call the functions which start with "__" as those are meant for internal use by the library itself. There is a readme file included in the ZIP which shall get you started. -

chrome-extensions-examples
All Chrome Extension examples collected into one repository
This is not an official mirror of the Chrome extension examples. Report any issues with the examples themselves to Google's issue trackers/forums. The Chrome Extensions examples did not exist as a Git repository, and browsing both the samples page and the VCViewer did not seem particularly handy. So, I decided to scrape the content into this repository for easier browsing and (possible) editing. -

clmtrackr
Javascript library for precise tracking of facial features
clmtrackr is a javascript library for fitting facial models to faces in videos or images. It currently is an implementation of constrained local models fitted by regularized landmark mean-shift, as described in Jason M. Saragih's paper. clmtrackr tracks a face and outputs the coordinate positions of the face model as an array. The library provides some generic face models that were trained on the MUCT database and some additional self-annotated images. Check out clmtools for building your own models. For tracking in video, it is recommended to use a browser with WebGL support, though the library should work on any modern browser. For some more information about Constrained Local Models, take a look at Xiaoguang Yan's excellent tutorial, which was of great help in implementing this library. -

co
The ultimate generator based flow-control goodness for nodejs
co is a small Node.js library that popularized generator-based coroutines to write asynchronous code that looks synchronous. By yielding promises (or thunks) inside a generator function, co resumes execution when the asynchronous work completes, eliminating deeply nested callbacks. It supports yielding arrays or objects of promises to run tasks concurrently, and it propagates errors naturally through try/catch, making control flow easier to reason about. The library arrived before async/await existed in Node.js and influenced how developers thought about structuring asynchronous programs. Even in a world with native async functions, co remains a concise illustration of cooperative concurrency and still works where generator syntax is preferred. Its API surface is intentionally tiny: wrap a generator, yield work, and let co drive the promise plumbing behind the scenes. -
