templUI
A growing collection of beautifully designed UI components for Go
templUI is a modern UI component library built specifically for Go applications using the templ templating language, offering a developer-first approach to building interfaces with strong type safety and performance. It provides a growing collection of beautifully designed, production-ready components styled with Tailwind CSS, allowing developers to construct modern web interfaces without relying on heavy frontend frameworks. One of its defining principles is code ownership, meaning developers can either import components directly or copy them into their projects using a CLI, ensuring full control over customization and long-term maintenance. The library avoids JavaScript frameworks entirely, instead relying on lightweight, vanilla implementations that prioritize speed and simplicity. templUI also emphasizes security and compliance, with features such as CSP-friendly rendering and no inline scripts, making it suitable for enterprise environments. -

tmi.js
Javascript library for the Twitch Messaging Interface
Connect to and interact with Twitch chat (IRC) from Node.js or a browser. Control the delay in milliseconds between JOIN requests when using the channels array option. Minimum of 300 milliseconds. If the identity has special permission from Twitch for a higher join rate then you should implement your own calls to the client.join method. Disable receiving JOIN/PART events for other users. Good for decreasing network traffic when joining lots of channels or you don't care about this data. After a threshold per channel Twitch stops sending this data so it may not be necessary for all cases. Channels to automatically join upon connecting. The rate of joins is controlled by the options.joinInterval option. Automatically reconnect the client if it gets disconnected for any reason. Sometimes Twitch will request the client to reconnect and tmi.js will disconnect and reconnect even if this option is set to false. -

tracking.js
A modern approach for Computer Vision on the web
The tracking.js library brings different computer vision algorithms and techniques into the browser environment. By using modern HTML5 specifications, we enable you to do real-time color tracking, face detection and much more, all that with a lightweight core (~7 KB) and intuitive interface. To get started, download the project. This project includes all of the tracking.js examples, source code dependencies you'll need to get started. Unzip the project somewhere on your local drive. The package includes an initial version of the project you'll be working with. While you're working, you'll need a basic HTTP server to serve your pages. Test out the web server by loading the finished version of the project. The main goal of tracking.js is to provide those complex techniques in a simple and intuitive way on the web. We believe computer vision is important to improve people's life, bringing it to the web will make this future a reality a lot faster. -

twitter-text
This code is used at Twitter to tokenize and parse text
Twitter Text Libraries. This code is used at Twitter to tokenize and parse text to meet the expectations for what can be used on the platform. This repository is a collection of libraries and conformance tests to standardize parsing of Tweet text. It synchronizes development, testing, creating issues, and pull requests for twitter-text's implementations and specification. These libraries are responsible for determining the quantity of characters in a Tweet and identifying and linking any URL, @username, #hashtag, or $cashtag. Emoji supported by twemoji always count as two characters, regardless of combining modifiers. This includes emoji which have been modified by Fitzpatrick skin tone or gender modifiers, even if they are composed of significantly more Unicode code points. Emoji weight is defined by a regular expression in twitter-text that looks for sequences of standard emoji combined with one or more Unicode Zero Width Joiners (U+200D). -

vex
A modern dialog library, configurable and easy to style
vex is a modern dialog library which is highly configurable, easily stylable, and gets out of the way. You'll love vex because it's tiny (5.6kb minified and gzipped), has a clear and simple API, works on mobile devices, and can be customized to match your style in seconds. Drop-in replacement for alert, confirm, and prompt. Easily configurable animations which are smooth as butter. Open multiple dialogs at once and close them individually or all at once. vex will run in any ES5-compatible environment, and includes polyfills for classList and Object.assign. For the most common usage of vex, you'll want to include vex, vex-dialog, the vex CSS file, and a theme file. For browserify/webpack, you'll still need to include the stylesheets on your page, but you can setup vex in your scripts. -

vue-countTo
It's a vue component that will count to a target number
Vue-countTo is a lightweight, dependency-free Vue component that smoothly animates numbers from a start value to an end value over a specified duration. It automatically detects whether to count up or down based on the given values. The component exposes props for timing, easing, and dynamic updates so you can adjust targets on the fly. Because it’s SSR-friendly, it can be used in universal apps without breaking server rendering. A live demo showcases common use cases like incremental updates and countdowns, making it easy to test parameters. Inspired by countUp.js, the component remains small and focused while embracing idiomatic Vue patterns. -

vue2-happyfri
Learning-oriented app that recreates a mobile food-ordering experience
vue2-happyfri is a learning-oriented Vue 2 application that recreates a mobile food-ordering experience to demonstrate how to structure a real-world single-page app. It shows how to compose UI from reusable components, wire up routing between views, and manage shared state for carts, users, and menus. The project emphasizes responsive, touch-friendly interactions and small polish details—like transitions, toasts, and loading states—that make the app feel production-ready. It includes examples of fetching and normalizing data, handling asynchronous flows, and keeping UI reactive to server responses. Developers can study folder structure, component boundaries, and patterns for passing data and events cleanly through the tree. As a whole, it provides a concrete blueprint for building consumer-grade Vue apps that balance clarity, scalability, and user experience. -

xy-ui
Future-proof native web components UI component library
xy-ui is a cross-framework UI component library built using native Web Components standards, enabling developers to create reusable and encapsulated UI elements that can work across different frameworks without dependency on a specific ecosystem. It leverages technologies such as Custom Elements and Shadow DOM to provide strong encapsulation, ensuring that styles and behaviors remain isolated and predictable across applications. The library is designed with a forward-looking approach to frontend development, focusing on native browser capabilities instead of framework-specific abstractions. It includes a wide range of UI components such as buttons, inputs, dialogs, sliders, tables, and date pickers, covering most common interface needs for modern web applications. Because it is framework-agnostic, xy-ui can be integrated into projects using Vue, React, or even plain JavaScript, making it highly flexible for diverse development environments. -

yo-yo.js
A tiny library for building modular UI components using DOM diffing
yo-yo is a tiny, modular JavaScript library for building UI components by combining template literals with efficient DOM diffing. The core idea behind yo-yo is to enable developers to write modular, dynamic views using ES6 tagged template syntax, then update those views by intelligently diffing and morphing the real DOM rather than re-rendering everything. It’s inspired by patterns found in larger UI frameworks but stays extremely lightweight—only a few kilobytes when minified and gzipped—by leveraging existing tools like bel (for templating) and morphdom (for DOM updates). yo-yo underpins some higher-level frameworks and is ideal for developers who want direct control over components without the overhead of a full reactive framework. Its simplicity and elegant API make it a favorite for small to medium front-end projects where performance and minimalism matter. -
