jQuery Terminal
JavaScript library for creating web-based terminals
jQuery Terminal is a JavaScript library for creating command-line interpreters in your applications. You can use this JavaScript Terminal library to create interactive web-based terminal applications on your website. Where commands are defined by you. You can define them on the server or in the browser's JavaScript. It can automatically call JSON-RPC service when the user types a command. Alternatively, you can provide an object with methods; each method will be invoked on the user's command (the python command can create python interpreter). An object can have nested objects which will create a nested interpreter (you can create an interactive menu of adventure games with this). You can also use a function in which you can parse user commands by yourself (you have full control of what users type into the terminal). It's ideal if you want to provide additional functionality for power users. -

jQuery contextMenu plugin & polyfill
jQuery contextMenu plugin & polyfill
The contextMenu Plugin was designed for web applications in need of menus on a possibly large amount of objects. Unlike implementations as a beautiful site's or trendskitchens' this contextMenu treats the menu as the primary object. That means, that a single menu is defined that can be used by multiple objects. Unlike the mentioned plugins, contextMenu doesn't need to bind itself to triggering objects. This allows injecting and removing triggers without having to re-initialize or update contextMenu. contextMenu can provide a simple list of clickable commands, or offer an in-menu form. This makes very simple attribute modification possible. Once a menu is registered, it cannot be altered. That means no commands can be added or removed from the menu. This allows contextMenu to keep a single definition in memory, which enables it to work with hundreds of trigger objects. contextMenu knows the two callbacks show and hide which can be used to update the state of commands within the menu. -

jest-puppe-shots
A Jest plugin for creating screenshots of React components
A Jest plugin for creating screenshots of React components with a little help of Puppeteer. A jest-puppy-shots is a Jest plugin that can help you create Visual Regression tests for your React components. If you ever used Enzyme or Snapshots you will love the jest-puppe-shots. The Snapshot testing approach is really awesome but it has one downside: it cannot be used to make visual regression tests of your components. Thanks to the Puppeteer API it's now possible to use the Chromium browser in Jest and create real screenshots of your components. -

joi-router
Configurable, input and output validated routing for koa
Easy, rich, and fully validated koa routing. koa-joi-router returns a constructor that you use to define your routes. The design is such that you construct multiple router instances, one for each section of your application which you then add as koa middleware. The route definition for the currently matched route is available via ctx.state.route. This object is not the exact same route definition object that was passed into koa-joi-router, nor is it used internally - any changes made to this object will not have an effect on your running application but is available to meet your introspection needs. Validating the output body and/or headers your service generates on a per-status-code basis is supported. This comes in handy when contracts between your API and client are strict e.g. any change in response schema could break your downstream clients. In a very active codebase, this feature buys you stability. If the output is invalid, an HTTP status 500 will be used. -

jscodeshift
A JavaScript codemod toolkit
jscodeshift is a toolkit for running codemods over multiple JavaScript or TypeScript files. It provides A runner, which executes the provided transform for each file passed to it. It also outputs a summary of how many files have (not) been transformed. A wrapper around recast, providing a different API. Recast is an AST-to-AST transform tool and also tries to preserve the style of original code as much as possible. As already mentioned, jscodeshift also provides a wrapper around recast. In order to properly use the jscodeshift API, one has to understand the basic building blocks of recast (and ASTs) as well. An AST node is a plain JavaScript object with a specific set of fields, in accordance with the Mozilla Parser API. The primary way to identify nodes is via their type. It's OK to not know the structure of every AST node type. The (esprima) AST explorer is an online tool to inspect the AST for a given piece of JS code. -

jstree
jquery tree plugin
jsTree is jquery plugin, that provides interactive trees. It is absolutely free, open-source and distributed under the MIT license. jsTree is easily extendable, themable and configurable, it supports HTML & JSON data sources and AJAX loading. jsTree functions properly in either box-model (content-box or border-box), can be loaded as an AMD module, and has a built in mobile theme for responsive design, that can easily be customized. It uses jQuery's event system, so binding callbacks on various events in the tree is familiar and easy. Themes can be autloaded too, but it is best for performance to include the CSS file. jsTree requires 1.9.0 or greater in your webpage. You can use a CDN version or include a local copy. Once the DOM is ready you can start creating jstree instances. jsTree uses events to notify you when something changes while users (or you) interact with the tree. -

lavish-axi
HTML is the new markdown. Lavish is the new editor for HTML artifacts
Lavish AXI is a local-first editor for reviewing and refining HTML artifacts produced by AI agents. It opens generated HTML in a browser so users can inspect the actual interactive result instead of relying on screenshots or long text descriptions. Users can pinpoint elements, select text ranges, annotate content, and send feedback directly back to the agent. Rendered Mermaid diagrams can also be edited as whiteboards. The tool is designed as an agent-native CLI with token-efficient output, long polling, and contextual disclosure. It can be used through an installable agent skill, run directly with npx, or integrated through session hooks and agent-plugin packaging. -

matchMedia() polyfill
matchMedia polyfill for testing media queries in JS
matchMedia() polyfill is a JavaScript polyfill that brings matchMedia-style media query testing to environments that need compatibility support. It lets developers test whether a CSS media type or media query applies directly from JavaScript. The library is useful for responsive behavior that depends on screen size, device type, orientation, or other media query conditions. It can be used with a companion addListener polyfill when code needs to react to changes over time. The project was used by tools such as Respond.js, FormFactor, and Modernizr, which reflects its role in older responsive web development workflows. It is most relevant for legacy browser support, educational reference, and projects that need to understand how JavaScript-based media query testing worked before broad native support. -

morgan
HTTP request logger middleware for node.js
This is a Node.js module available through the npm registry. Installation is done using the npm install command. Create a new morgan logger middleware function using the given format and options. The format argument may be a string of a predefined name, a string of a format string, or a function that will produce a log entry. The format function will be called with three arguments tokens, req, and res, where tokens is an object with all defined tokens, req is the HTTP request and res is the HTTP response. The function is expected to return a string that will be the log line, or undefined / null to skip logging. Write log line on request instead of response. This means that a requests will be logged even if the server crashes, but data from the response (like the response code, content length, etc.) cannot be logged. To define a token, simply invoke morgan.token() with the name and a callback function. -

mui
High-performance framework closest to native APP experience
The gap between performance and experience has always been the primary reason for mobile app developers to abandon HTML5. The browser’s natural page-cutting white screen, the unbearable turning animation, the jittering of floating elements, and the inability to pull down to refresh smoothly, all of which frustrate HTML5 developers, especially when they get a low-end Android machine to run, and the phone falls. On the other hand, the browser default control styles are few and ugly, making a beautiful control is very troublesome, and there are some simple UI frameworks but low performance. The mui framework effectively solves these problems. This is a framework that can facilitate the development of high-performance apps, and it is also the framework that is closest to the effect of native apps. -

natural
General natural language facilities for node
"Natural" is a general natural language facility for nodejs. It offers a broad range of functionalities for natural language processing. Tokenizing, stemming, classification, phonetics, tf-idf, WordNet, string similarity, and some inflections are currently supported. It’s still in the early stages, so we’re very interested in bug reports, contributions and the like. Note that many algorithms from Rob Ellis’s node-nltools are being merged into this project and will be maintained from here onward. While most of the algorithms are English-specific, contributors have implemented support for other languages. Russian stemming has been added and Spanish stemming has been added, as well. Stemming and tokenizing in more languages have been added. If you’re just looking to use natural without your own node application, you can install via NPM. -
