Meny
A three dimensional and space effecient menu
Meny is an off-canvas, edge-triggered menu concept that slides into view when the user moves the mouse to the edge of the screen or performs a similar gesture. It was created to explore more playful and discoverable navigation than the usual hamburger menu, especially on large screens. The menu itself lives off-screen and is revealed with a smooth CSS transform, leaving most of the page untouched. Because it’s just HTML, CSS, and a bit of JavaScript, it’s easy to restyle for sidebars, tool palettes, or documentation navigation. Meny works particularly well on interactive sites, demos, or dashboards where you want quick access to options without permanent UI clutter. It’s a good example of “progressive” navigation: always there, but not always visible. -

Microbundle
Zero-configuration bundler for tiny modules
Microbundle produces esm, cjs, umd bundles with your code compiled to syntax that works pretty much everywhere. While it's possible to customize the browser or Node versions you wish to support using a browserslist configuration, the default setting is optimal and strongly recommended. In addition to the above formats, Microbundle also outputs a modern bundle specially designed to work in all modern browsers. This bundle preserves most modern JS features when compiling your code, but ensures the result runs in 95% of web browsers without needing to be transpiled. Specifically, it uses Babel's "bugfixes" mode (previously known as preset-modules) to target the set of browsers that support <script type="module"> - that allows syntax like async/await, tagged templates, arrow functions, destructured and rest parameters, etc. The result is generally smaller and faster to execute than the plain esm bundle. -

MixItUp 3
Library for animated filtering, sorting, insertion, removal and more
MixItUp is a high-performance, dependency-free library for animated DOM manipulation, giving you the power to filter, sort, add and remove DOM elements with beautiful animations. MixItUp plays nice with your existing HTML and CSS, making it a great choice for responsive layouts and compatible with inline-flow, percentages, media queries, flexbox and more. MixItUp is open source and free to use for non-commercial, educational and non-profit use. For use in commercial projects, a commercial license is required. Most commonly, MixItUp is applied to a "container" of "target" elements, which could be a portfolio of projects, a list of blog posts, a selection of products, or any kind of UI where filtering and/or sorting would be advantageous. Targets can be filtered using any valid selector e.g. '.category-a', and are sorted via optional custom data attributes e.g. 'data-order'. -

Modaal
An accessible dialog window library for all humans
It's hard to find a plugin with the right mix of quality, flexibility and accessibility. We thought it would be interesting to develop something that would work in a variety of projects, furthering the cause for an accessible web. Modaal has been developed to support common jQuery configuration options, but in an effort to extend functionality and widen its usage we've developed support for inline data-option-name attribute support. The Modaal video type has been tested thoroughly using both Vimeo and Youtube. We transplant this URL into an iframe which then each service provider controls all the necessary playback from there. Modaal window to prompt the user to Confirm or Cancel a particular action. Content can be pushed through including callback events as necessary. By default once open, it can not be closed until an action has been selected (such as Confirm/Cancel). -

Modern Errors
Handle errors in a simple, stable, consistent way
Handle errors in a simple, stable, consistent way. Exporting and documenting all error classes allows consumers to check them. This also enables sharing error classes between modules. Error properties that are internal or secret can be prefixed. This makes them non-enumerable, which prevents iterating or logging them. -

Monkberry
Monkberry is a JavaScript library for building web user interfaces
Monkberry is a highly optimized JavaScript library for building web user interfaces, designed to be extremely small, fast, and simple to use. It uses a template-based approach where UI components are written in a custom templating syntax that compiles directly into efficient JavaScript code. Unlike frameworks that rely on a virtual DOM, Monkberry updates only the necessary parts of the actual DOM, resulting in significantly improved performance. Its compiled templates leverage JavaScript engine optimizations to reduce overhead and improve rendering speed. The library is intentionally minimal, with a small footprint of around one kilobyte, making it ideal for performance-critical applications or environments with limited resources. It also includes features like custom tags, source maps, and a straightforward component structure, enabling developers to build modular interfaces without complexity. -

Mousetrap
Simple library for handling keyboard shortcuts in Javascript
Mousetrap is a standalone library with no external dependencies. It weighs in at around 2kb minified and gzipped and 4.5kb minified. Mousetrap has been tested and should work in Internet Explorer 6+, Safari, Firefox, and Chrome. The bind method is the main call you will be making. This will bind a specified keyboard command to a callback method. If you want to bind multiple key commands to the same callback you can pass in an array for the first argument. Mousetrap 1.4 introduced a generic mod helper which lets you set cross platform shortcuts. The sequence of keys feature was inspired by Gmail. Any keys separated by a space will be considered a sequence. If you type each key in order the final one in the sequence will trigger the callback. If you type a key not in the sequence or wait too long the sequence will reset. You can also make a sequence that includes key combinations within it. -

MythCore
Myth Framework Core Libraries (part of MythSDP)
MythCore is a PHP framework that allows the developer to use a C# .NET like object oriented programming approach. It provides the essential classes that the MythSDP platform and the MythFramework builds upon. The goal is to create a library that enables the programmer to use a fully object oriented approach that has the "feel" of .NET and Java programming. Our main goal is ease of use and rapid application development. However, performance and small-footprint are some of the main design goals as well. -

N-chat
Multiplayer chat rooms built with Express + Socket.IO
N-chat is a small educational group-chat application created with Express and Socket.IO. It demonstrates how a Node.js server can maintain real-time connections and broadcast events among browser clients. Users sign in with a display name that is stored in a cookie, and duplicate active names are rejected. The server tracks connected users and announces when someone enters or leaves the room. Messages can be sent publicly to everyone or privately to a selected online user. The browser interface updates the participant list, timestamps messages, and attempts to reconnect after a lost server connection. Because it relies on early Express and Socket.IO releases, the repository is best treated as a legacy learning example rather than a modern chat platform. -

NG6
An AngularJS Starter repo for AngularJS + ES6 + Webpack
NG6 is a starter project for building single-page applications with AngularJS 1.x, modern ES6 JavaScript, and Webpack as the module bundler. It provides a minimal but opinionated boilerplate that shows best practices for structuring a scalable Angular app using a fully componentized file layout. The project wires together Webpack and Babel to handle ES6 transpilation, asset bundling, and hot reloading during development. Gulp is used as an orchestrator to run Webpack, start a development server, and generate Angular boilerplate via tasks. The repository also includes a complete testing setup using Karma, Mocha, Chai, and Webpack so tests run through the same pipeline as application code. Styles are handled via SASS (node-sass), with each component encouraged to bundle its own styles, templates, and tests for strong locality. Overall, NG6-starter is designed as a “de facto” reference for developers who want to learn and adopt a modern workflow. -

NN-SVG
Publication-ready NN-architecture schematics
Illustrations of Neural Network architectures are often time-consuming to produce, and machine learning researchers all too often find themselves constructing these diagrams from scratch by hand. NN-SVG is a tool for creating Neural Network (NN) architecture drawings parametrically rather than manually. It also provides the ability to export those drawings to Scalable Vector Graphics (SVG) files, suitable for inclusion in academic papers or web pages. The tool provides the ability to generate figures of three kinds: classic Fully-Connected Neural Network (FCNN) figures, Convolutional Neural Network (CNN) figures of the sort introduced in the LeNet paper, and Deep Neural Network figures following the style introduced in the AlexNet paper. The former two are accomplished using the D3 javascript library and the latter with the javascript library Three.js. NN-SVG provides the ability to style the figure to the user's liking via many size, color, and layout parameters. -

NanoNeuron
NanoNeuron is 7 simple JavaScript functions
Nano-Neuron is a didactic project that reduces the idea of a neuron to a handful of tiny JavaScript functions so learners can see “learning” in action without heavy frameworks. It demonstrates how a scalar input can be linearly transformed with a weight and bias, then adjusted via gradient updates to fit a simple mapping such as Celsius-to-Fahrenheit conversion. The code emphasizes readability over performance, inviting you to step through calculations and watch parameters converge. Because every concept is expressed in a few lines, it’s easy to tinker—change learning rates, swap cost functions, or visualize error curves. The repository bridges the gap between formulae and intuition by making each update transparent and observable. It’s ideal for absolute beginners who want to internalize core ideas before moving on to multi-layer networks and libraries. -

NativeUI
The most crossbrowser web UI library that uses native browser elements
NativeUI is a CSS and JavaScript library that adheres to the KISS principle and focuses on utilizing standard features provided by browsers, which are most optimized for each specific platform, and therefore provide the best performance and user experience. The library ensures cross-browser behavior and styling of built-in browser elements of user interface and text formatting, adding commonly used user interface elements such as modal windows, image viewer, menus, tabs, form messages, etc. It also contains some useful JavaScript functions for development, such as request() and getFormData().

Neiki's Charts
Lightweight SVG chart Web Component
Neiki's Charts is a lightweight SVG chart library built as a native Web Component. Drop a single script tag into any HTML page and get four chart types — Line, Bar, Pie, and Scatter — with no build step, no framework, and zero dependencies. CSS is bundled automatically, so one file is all you need. The component uses Shadow DOM for style encapsulation and fits cleanly into any project without CSS conflicts. Charts are fully responsive, support light and dark themes with automatic prefers-color-scheme detection, and expose a simple JS API for data and options. Tooltips, legends, animations, and grid lines are all controlled through standard HTML attributes. All rendering is pure SVG — no Canvas — making charts scalable, printable, and inspectable in DevTools. Accessibility is built in with proper ARIA roles, keyboard-navigable legends, and full prefers-reduced-motion support.
