    Material Design

    Material Design

    Material design for AngularJS

    AngularJS Material is an implementation of Google's Material Design Specification (2014-2017). This project provides a set of reusable, well-tested, and accessible UI components for AngularJS developers. AngularJS Material has entered the Long Term Support (LTS) period. The AngularJS Material library is a mature and stable product that is ready for production use. Developers should note that AngularJS Material works only with AngularJS 1.x. AngularJS 1.x is now in Long Term Support (LTS) mode, so, current development efforts are focused on bug fixes, accessibility, performance, and minor enhancements. Material Design is a specification for a unified system of visual, motion, and interaction design that adapts across different devices. Our goal is to deliver a lean, lightweight set of AngularJS-native UI elements that implement the material design specification for use in AngularJS single-page applications (SPAs).

    Meny

    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

    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.

    Modaal

    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

    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

    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

    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

    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.

    NG6

    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.
