    Hotkeys JS

    Hotkeys JS

    A robust Javascript library for capturing keyboard input

    hotkeys-js is a tiny, framework-agnostic library for binding keyboard shortcuts in the browser, from simple key presses to complex combos and sequences. It provides a declarative API to register handlers like ctrl+k, shift+alt+p, or g g, and it normalizes key behavior across major browsers. The library includes scoping, so the same shortcut can trigger different actions depending on page context, and it offers filters to ignore inputs when the user is typing in form fields. You can enable or...

    ExpressJS.com

    The Express.js Website

    ...Versioned docs help readers match API behavior to the framework version they’re running, reducing confusion during upgrades. The site showcases common patterns through concise examples, making it easy to translate concepts into working code. In addition to core Express usage, the documentation surfaces ecosystem guidance on things like security headers, structured logging, and integration with view engines or ORMs. Because it is open to community contributions, the documentation evolves alongside Express itself, reflecting real-world questions and solutions.

    EdgeChains.js is Full-Stack GenAI library

    EdgeChains.js is a full-stack generative AI library that provides front-end, back-end, APIs, prompt management, and distributed computing capabilities, with core prompts and chains managed declaratively in Jsonnet. At EdgeChains, we take a unique approach to Generative AI - we think Generative AI is a deployment and configuration management challenge rather than a UI and library design pattern challenge. We build on top of a tech that has solved this problem in a different domain - Kubernetes Config Management - and bring that to Generative AI. ...

    two.js

    two.js

    A renderer agnostic two-dimensional drawing api for the web

    ...It is renderer agnostic enabling the same api to draw in multiple contexts: svg, canvas, and webgl. Two.js is deeply inspired by flat motion graphics. As a result, two.js aims to make the creation and animation of flat shapes easier and more concise. At its core two.js relies on a scenegraph. This means that when you draw or create an object (a Two.Path or Two.Group), two actually stores and remembers that. After you make the object you can apply any number of operations to it. Two.js has a built in animation loop. It is simple in nature and can be automated or paired with another animation library. ...

In order to use nivo, you have to install the @nivo/core package and then choose some of the scoped @nivo packages according to the charts you wish to use. Given an array of data series having an id and a nested array of points (with x, y properties), it will compute the line for each data series. All datum having null x or y will be treated as holes, thus portions of the corresponding line will be skipped. ...

    layui

    layui

    Classic modular front-end UI framework

    ...Layui (homonym: UI-like) is a front-end UI framework written with its own module specifications, following the writing and organization of native HTML/CSS/JS, with a very low threshold and ready to use. Its exterior is minimalist, but it does not lose its fullness. The volume is light and the components are abundant. Every detail from the core code to the API has been carefully crafted, which is very suitable for the rapid development of the interface. The first version of layui was released in the golden autumn of 2016. It is different from those UI frameworks based on the underlying MVVM.

    Static AST checker for a11y rules on JSX elements

    ...This plugin does a static evaluation of the JSX to spot accessibility issues in React apps. Because it only catches errors in static code, use it in combination with axe-core/react to test the accessibility of the rendered DOM. Consider these tools just as one step of a larger a11y testing process and always test your apps with assistive technology. If you installed ESLint globally (using the -g flag in npm, or the global prefix in yarn) then you must also install eslint-plugin-jsx-a11y globally. To enable your custom components to be checked as DOM elements, you can set global settings in your configuration file by mapping each custom component name to a DOM element type. ...

It has proven itself in production environments. Chokidar does still rely on the Node.js core fs module, but when using fs.watch and fs.watchFile for watching, it normalizes the events it receives, often checking for truth by getting file stats and/or dir contents.

The core model is highly compact at around 66 million parameters, yet benchmarks show it can generate speech up to 167× faster than real time on modern consumer hardware and significantly outpace popular cloud TTS APIs in throughput and real-time factor. Supertonic is designed to handle real-world text gracefully, including numbers, dates, currency symbols, abbreviations, and technical units, without requiring heavy pre-processing or custom text normalization. ...

However, Poppers.js via react-popper is relied upon for advanced positioning of content like Tooltips, Popovers, and auto-flipping Dropdowns. There are a few core concepts to understand in order to make the most out of this library. Your content is expected to be composed via props.children rather than using named props to pass in Components. Attributes in this library are used to pass in-state, conveniently apply modifier classes, enable advanced functionality (like tether), or automatically include non-content-based elements.
