    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.

    clipboard.js

    clipboard.js

    A modern approach to copy text to clipboard

    clipboard.js offers a better, more modern approach to copying text from the clipboard. It isn’t dependent on Flash or any bloated framework, just 3kb gzipped. clipboard.js eliminates all the hassles that come with copying text to the clipboard, such as the many steps needed to configure, or the hundreds of KBs you need to load. With clipboard.js you can copy content from another element, cut text from another element, and copy text from attribute. It supports most popular browsers and gracefully degrades if you need to support older browsers.

    clmtrackr

    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

    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.

    csg.js

    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

    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

    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

    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.

    decimal.js

    decimal.js

    An arbitrary-precision Decimal type for JavaScript

    decimal.js is a JavaScript library that provides an arbitrary-precision decimal data type designed to overcome the limitations of native floating-point arithmetic in JavaScript. It allows developers to perform accurate calculations with numbers of virtually unlimited precision, making it especially useful for financial, scientific, and high-precision applications. Unlike standard JavaScript numbers, which can produce rounding errors due to binary representation, decimal.js ensures consistent and predictable results by operating on decimal values directly. The library defines a Decimal constructor that accepts numbers, strings, or existing Decimal instances, enabling flexible usage across different input types. It supports a wide range of mathematical operations, including arithmetic, logarithmic, trigonometric, and exponential functions, making it significantly more comprehensive than simpler numeric libraries.

    electron-vue-admin

    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.

    embed-js

    embed-js

    A lightweight plugin to embed emojis, media, maps, tweets, code, etc.

    A lightweight JavaScript plugin to embed emojis, media, maps, tweets, code and services. embed.js was developed with a modern JavaScript workflow in mind. To use it, it's recommended you have a build system in place that can transpile ES6, and bundle modules. But at the same time, you get an already transpiled version to make your development easier. If you’re using npm package manager with a module bundler like Webpack or Browserify to consume CommonJS modules, you can use the default UMD build of the plugin by simply requiring it. The render() method renders the resulting string in the block. The .render() method also returns a promise. Optionally you can also pass a string which will be processed by the plugin.
