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. -

classList.js
Cross-browser element.classList
classList.js is a cross-browser JavaScript shim that provides the standard element.classList interface where it is missing or incomplete. It lets developers manipulate CSS class names through a token-based API instead of manually editing className strings. The implementation includes methods for adding, removing, checking, toggling, replacing, and retrieving individual class tokens. It also normalizes partial native implementations that accept only one token or lack the forced-state argument for toggle. The script works in nearly all historical browsers except Internet Explorer 7 and earlier. Its small standalone and minified builds make it suitable for legacy sites that need consistent DOM class handling without a framework. -

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. -

core-js
Modular standard library for JavaScript
Modular standard library for JavaScript. Includes polyfills for ECMAScript up to 2021: promises, symbols, collections, iterators, typed arrays, many other features, ECMAScript proposals, some cross-platform WHATWG / W3C features and proposals like URL. You can load only required features or use it without global namespace pollution. The maintainers of core-js and the maintainers of thousands of other packages are working with Tidelift to deliver commercial support and maintenance for the open source dependencies you use to build your applications. Save time, reduce risk, and improve code health, while paying the maintainers of the exact dependencies you use. If you use core-js with the extension of native objects, recommended load all core-js modules at the top of the entry point of your application, otherwise, you can have conflicts. -

csg.js
Constructive solid geometry on meshes using BSP trees in JavaScript
csg.js is a JavaScript library implementing constructive solid geometry (CSG) operations on polygonal meshes using BSP trees. With CSG, you build complex 3D shapes by combining primitives using Boolean operations like union, subtract, and intersect. The library focuses on clarity and correctness: its implementation is intentionally concise and readable so developers can understand the algorithm, while still correctly handling tricky edge cases such as overlapping coplanar polygons. A WebGL-based demo shows how two solids can be combined interactively in the browser, making it a great educational tool for learning CSG concepts. The API allows you to create primitives (cubes, spheres, etc.) and then combine or transform them programmatically, producing new mesh geometry for rendering or export. Because it is dependency-light and pure JavaScript, csg.js can be integrated into custom modeling tools, CAD-like apps, games, or procedural modeling pipelines running in the browser or Node. -

currency.js
A javascript library for handling currencies
currency.js is a lightweight JavaScript library designed to handle currency values with precision by avoiding common floating point arithmetic issues inherent in JavaScript. It achieves this by internally representing values as integers, which allows for accurate calculations even when dealing with decimals. The library provides a simple and intuitive API for performing operations such as addition, subtraction, multiplication, and division on monetary values. It is optimized for performance and minimal footprint, making it ideal for applications where bundle size and speed are important considerations. currency.js also includes formatting capabilities, allowing developers to display currency values in user-friendly formats with customizable symbols and separators. Its simplicity makes it particularly appealing for smaller projects or cases where a full financial library is not required. -

dat.GUI
dat.gui is a lightweight controller library for JavaScript
A lightweight graphical user interface for changing variables in JavaScript. The easiest way to use dat.GUI in your code is by using the built source at build/dat.gui.min.js. These built JavaScript files bundle all the necessary dependencies to run dat.GUI. If you're using a server with a Content Security Policy in place that blocks 'unsafe-inline', you will have problems when dat.gui.js tries to inject style information. To get around this, load 'build/dat.gui.css' as an external style sheet. With the npm run build script you can build development and production version of scripts. And with the npm run dev script you can build development version of script and watch for changes. -

dc.js
Multi-Dimensional charting built to work natively with crossfilter
dc.js is a javascript charting library with native crossfilter support, allowing highly efficient exploration on large multi-dimensional datasets (inspired by crossfilter's demo). It leverages d3 to render charts in CSS-friendly SVG format. Charts rendered using dc.js are data driven and reactive and therefore provide instant feedback to user interaction. Dimensional charting built to work natively with crossfilter rendered using d3.js. In dc.js, each chart displays an aggregation of some attributes through the position, size, and color of its elements, and also presents a dimension which can be filtered. When the filter or brush changes, all other charts are updated dynamically, using animated transitions. dc.js is an easy yet powerful javascript library for data visualization and analysis in the browser and on mobile devices. -

deb.js
Minimalistic JavaScript library for debugging in the browser
deb.js is a minimal JavaScript debugging library for browser-based development. It works at the function level by letting developers add a debugging wrapper to existing functions. When those functions run, deb.js groups console output and places logs in clearer execution context. It can show stack traces, passed arguments, and execution time, which helps developers understand how functions behave at runtime. The library is very small and can be added near the top of a page before other scripts. It also had a Chrome extension workflow, making it easier to inject debugging behavior into pages during development. -

document-register-element
A stand-alone working lightweight version of the W3C
document-register-element is a lightweight polyfill that brought Custom Elements APIs to browsers without complete native support. It supports both the older V0 model and much of the V1 specification, including autonomous elements and customized built-in elements. Developers can define components with lifecycle callbacks that respond to creation, connection, removal, and observed attribute changes. The package uses feature detection so modern browsers can retain native behavior instead of receiving unnecessary patches. It can be loaded through npm, CommonJS, AMD, bundlers, a script tag, or a CDN. The repository is archived and deprecated, and its maintainer recommends newer custom-elements packages for current projects. -

electron-vue-admin
Vue electron admin template web
Electron-vue-admin is an admin dashboard scaffold that bundles Vue.js with Electron to deliver a desktop admin experience. It is based on the well-known vue-admin-template and generated with electron-vue tooling via Vue CLI. The project aims to let teams reuse familiar Vue components, routing, and permission models while packaging the app as a cross-platform desktop application. Because it inherits from the template ecosystem, you can incorporate patterns like Element UI components, axios-based API calls, and role-based navigation. It’s useful for internal tools that benefit from native-like desktop packaging, offline capabilities, or OS-level integrations. The repository provides a recognizable structure so Vue developers can get productive quickly without learning a new desktop-specific framework from scratch. -
