VenoBox
Responsive jQuery lightbox plugin
Responsive modal window javaScript plugin, touch swipe gallery. Just another responsive lightbox plugin, suitable for images, inline content, iFrames, and videos. The big difference compared to many other plugins is that VenoBox calculates the max width of the image displayed and preserves its height if is taller than the window (so in small devices you can scroll down the content, avoiding vertical microscopic resized images). -

VivaGraph
Graph drawing library for JavaScript
VivaGraphJS is a powerful, high-performance graph drawing library for JavaScript that enables developers to visualize complex networks directly in the browser or in Node.js environments. It is designed for speed and scalability, handling large graph datasets with smooth rendering and interactive capabilities such as dragging nodes and zooming. The library supports multiple rendering backends including SVG, WebGL, and Canvas, allowing developers to choose the best balance of performance and visual fidelity for their use case. Its layout algorithms help position nodes in aesthetically pleasing arrangements using force-directed simulations that adjust dynamically as the graph evolves. VivaGraphJS is modular, so you can extend or customize layouts, rendering, and interaction logic to fit specialized applications such as social network analysis, dependency mapping, or knowledge graphs. -

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.js modal
Easy to use, highly customizable Vue.js modal library
Easy to use, highly customizable Vue.js modal library. This library is contributor-driven. It is not backed by any company, which means that all contributions are voluntary and done by the people who need them. If you need something improved, added, or fixed, please contribute it yourself. Please keep in mind that maintainers volunteer their free time to work on this project and have no obligation to reply on the issues, tailor library for specific use-cases or perform customer support. Dialog is a simplified version of the modal which has most parameters set by default and is useful for quick prototyping, alerts, etc. Dialog is merely an example of how easy it is to create modals that fit your project needs. Nevertheless, you can use it if you set dialog, true in plugin configuration. In order to instantiate modals at runtime (for lazy-loading or de-cluttering templates), it is possible to create modals dynamically. -

WTFJS
A list of funny and tricky JavaScript examples
WTFJS is a curated collection of JavaScript “gotchas” and puzzling examples that reveal surprising corners of the language. Each entry presents a small snippet, explains why the behavior occurs, and ties it back to the specification or engine rules. The repository covers coercion quirks, edge-case comparisons, floating-point oddities, prototype traps, and scoping pitfalls, among others. It’s designed as both a fun read and a serious learning aid, helping developers build an intuition for how JavaScript evaluates expressions. By highlighting common misconceptions, it encourages safer coding patterns and more reliable mental models. Teachers, interviewers, and learners use it to spark discussion and deepen understanding of JavaScript’s semantics. -

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. -

Webshim
Webshims Lib is a modular capability-based polyfill-loading library
Webshim is a deprecated modular polyfill-loading library created to help developers use HTML5 features across browsers with inconsistent native support. It was designed around capability detection, meaning it loads only the needed polyfills instead of treating every browser the same. The library was especially useful when older browsers lacked reliable support for modern form controls, media elements, and other HTML5 APIs. It helped front-end developers build more consistent user experiences during a period when browser support varied widely. The project depends on the older JavaScript ecosystem and is not compatible with newer jQuery 3.x workflows. Today, it is best understood as a legacy compatibility tool for older web projects rather than a modern front-end dependency. -
15
XDomain
A pure JavaScript CORS alternative
XDomain is a JavaScript library designed to enable cross-domain communication in web applications, addressing limitations imposed by the browser’s same-origin policy. It provides a simple API for making cross-origin requests, allowing developers to interact with external resources without requiring complex server-side configurations. The library works by creating a proxy mechanism that facilitates communication between different domains in a secure and controlled manner. It is particularly useful for legacy environments where modern solutions like CORS may not be fully supported or easily configurable. XDomain emphasizes compatibility and ease of integration, making it suitable for a wide range of web applications that need to communicate across domains. Its lightweight design ensures minimal impact on performance while still providing the necessary functionality for cross-domain requests. -

You (Might) Don't Need jQuery
Examples of how to do query, style, dom, ajax, event etc like jQuery
You Don’t Need jQuery is a practical reference that maps common jQuery patterns to modern native JavaScript alternatives. It explains how current browser APIs can handle many tasks that once required jQuery. The guide covers selectors, CSS and style changes, DOM manipulation, Ajax, events, utility helpers, promises, animation, and browser support. It is written for developers who maintain older front-end code or want to reduce dependency weight in newer projects. The project also makes clear that jQuery is still valid in many cases, so the goal is guidance rather than blanket replacement. Its translated versions make the material accessible to a wide international developer audience. -

Zebra_Tooltips
A lightweight tooltips plugin for jQuery
Zebra_Tooltips is a lightweight (around 5KB minified) jQuery plugin for creating simple, but smart and visually attractive tooltips, featuring nice transitions and offering a wide range of configuration options. Tooltips may also be shown and hidden using the API. When shown programmatically, the tooltips will feature a “close” button and clicking it will be the only way of closing tooltips opened this way. This is very useful for drawing users’ attention to specific areas of a website. Appearance can be easily customized both through JavaScript and/or CSS. Also, tooltips can be aligned left, center or right relative to the parent element. Zebra_Tooltips make use of NO IMAGES (uses CSS3 for rounded corners and drop shadow and falls back gracefully for browsers that don’t support CSS3) and the tooltips can be attached to any element not just anchor tags! Works in all major browsers (Firefox, Opera, Safari, Chrome, Internet Explorer 6+) -

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.
