Vivus.js
JavaScript library to make drawing animation on SVG
Vivus is a lightweight JavaScript class (with no dependencies) that allows you to animate SVGs, giving them the appearence of being drawn. There are a variety of different animations available, as well as the option to create a custom script to draw your SVG in whatever way you like. Every path element is drawn at the same time with a small delay at the start. This is currently the default animation. Each line is drawn synchronously. They all start and finish at the same time, hence the name `sync`. Each path element is drawn one after the other. This animation gives the best impression of live drawing. To give more freedom, it's possible to override the animation of each path and/or the entire SVG. It works a bit like the CSS animation timing function. But instead of using a cubic-bezier function, it use a simple JavaScript function. It must accept a number as parameter (between 0 to 1), then return a number (also between 0 and 1). It's a hook. -

Vue-Video-Player
@videojs component for @vuejs
video.js player component for Vue. The Video.js player is a component. Like all components, you can define what children it includes, what order they appear in, and what options are passed to them. Components can be given custom options via the lower-camel-case variant of the component name (e.g. controlBar for ControlBar). These can be nested in a representation of grandchild relationships. Video.js playback technologies (i.e. "techs") can be given custom options as part of the options passed to the videojs function. They should be passed under the lower-case variant of the tech name (e.g. "html5"). -

Vue-fullpage.js
Official Vue.js wrapper for fullPage.js
Vue-fullpage.js is the official Vue wrapper around the popular fullPage.js library, making it easy to build full-screen scrolling, section-based websites in Vue 3. It exposes a <full-page> component that encapsulates the underlying fullPage.js behavior, letting you declare each scrolling section as regular Vue markup while configuring options through a Vue props object. The wrapper supports installation via npm and works both with modern bundlers like Vite and as a browser-loaded module from a CDN, so you can integrate it in many different project setups. You can pass any fullPage.js options and callbacks into the wrapper, including advanced features like horizontal sliders, scroll overflow handling, and plugin extensions, simply by providing an options object. The project supports both commercial and open-source licensing: commercial licenses for proprietary projects and GPLv3 for open-source apps, aligning with fullPage.js’s licensing model. -

Vue.js Analysis
Vue.js source code analysis
Vue.js Analysis is an open-source Chinese ebook and companion learning resource that analyzes the Vue.js source code in depth. It was created to help learners understand Vue’s implementation principles in a more systematic way than scattered blog posts. The project focuses on Vue 2.x internals, including initialization, reactivity, virtual DOM, component rendering, template compilation, lifecycle behavior, and related architectural ideas. It is connected to a paid video course but keeps the ebook material openly available for reading. The repository is best suited for front-end developers who already know Vue usage and want to understand how the framework works underneath. Its value is in turning a complex framework codebase into a structured source-code study path. -

Water.css
A drop-in collection of CSS styles to make simple websites
water.css is a “classless” CSS framework that instantly beautifies plain HTML without adding custom classes to your markup. By targeting native HTML elements—headings, paragraphs, forms, tables, and buttons—it applies sensible defaults for spacing, typography, and contrast, producing a clean, readable layout out of the box. The stylesheet is intentionally small and dependency-free, making it a convenient drop-in for prototypes, documentation, and minimalist sites where heavy frameworks are overkill. It includes automatic dark and light themes and exposes CSS variables so you can adjust colors or spacing while keeping the overall aesthetic. Because it respects semantic HTML, it plays well with accessibility tools and reduces the risk of brittle component overrides. The result is a fast path to “good enough” styling that remains easy to customize when a project grows. -

Webogram
Telegram web application, GPL v3
Telegram offers great apps for mobile communication. It is based on the MTProto protocol and has an Open API. I personally like Telegram for its speed and cloud-support (that makes a web app possible, unlike in the case of WA and others). MTProto data can be carried over HTTP (SSL is also supported), so this project is my take at creating one. Hosted version: the app is downloaded via HTTPS as a usual website. Will be available offline due to application cache. Packed version, the app is downloaded at once in a package via HTTPS. The package is updated less frequently than the Web-version. The app is based on the AngularJS JavaScript framework, and written in pure JavaScript. jQuery is used for DOM manipulations, and Bootstrap as the CSS-framework. The project repository is based on angularjs-seed and includes gulp tasks, so it's easy to launch the app locally on your desktop. -

Webpack library starter
Webpack based boilerplate for producing libraries
Webpack library starter is a boilerplate project for building JavaScript or TypeScript libraries with Webpack. It is designed for authors who want to publish reusable packages without setting up the build pipeline from scratch. The starter accepts ES6 or TypeScript source code and outputs a universal library format that can work across different JavaScript environments. It includes a Jest test setup so library behavior can be verified during development. The project is useful for small utilities, shared browser libraries, and packages that need a predictable publishing foundation. It is best viewed as a practical starting template rather than a full framework, giving developers structure while leaving room for customization. -

Zepto.js
JavaScript library for modern browsers with a jQuery compatible API
Zepto is a minimalist JavaScript library for modern browsers with a largely jQuery-compatible API. If you use jQuery, you already know how to use Zepto. While 100% jQuery coverage is not a design goal, the APIs provided match their jQuery counterparts. The goal is to have a ~5-10k modular library that downloads and executes fast, with a familiar and versatile API, so you can concentrate on getting stuff done. Zepto is open source software and is released under the developer and business-friendly MIT license. Note that some optional features of Zepto specifically target mobile browsers; as the original project goal was to specifically provide a leaner alternative to jQuery for the mobile web. Zepto is a good choice for browser extensions (for Safari, Chrome and Firefox) and to develop HTML-based views within native app frameworks, such as PhoneGap. In short, Zepto is expected to work in every modern browser and browser-like environment. -

ZeroClipboard
The ZeroClipboard library to copy text to the clipboard
The ZeroClipboard library provides an easy way to copy text to the clipboard using an invisible Adobe Flash movie and a JavaScript interface. The "Zero" signifies that the library is invisible and the user interface is left entirely up to you. To test this page locally, checkout the gh-pages branch, install jekyll and run jekyll serve to open localhost:4000. This is achieved by automatically floating the invisible movie on top of a DOM element of your choice. Standard mouse events are even propagated out to your DOM element, so you can still have rollover and mouse down effects. To setup, the project for local development starts with these commands in your terminal. Before submitting a pull request you'll need to validate, build, and test your code. Run the default grunt task in your terminal.
