HyperUI
Free Tailwind CSS v4 components for your next project
HyperUI is a large, copy-and-paste library of Tailwind CSS components aimed at speeding up interface building without adding heavy JavaScript. It groups components by common product needs—navigation, hero sections, pricing, forms, cards, tables, and full e-commerce flows—so teams can assemble pages quickly from consistent building blocks. Each snippet is written as semantic HTML with Tailwind utility classes, making it easy to customize spacing, color, and typography through a project’s Tailwind config. The components are responsive by default, using grid and flex patterns that adapt cleanly from mobile to widescreen layouts. Accessibility is treated pragmatically: markup favors proper roles and focus states, and most interactive behaviors can be wired with lightweight libraries or framework code if desired. Because everything is plain markup, adoption is frictionless in any stack (React, Vue, Svelte, Rails, Laravel), and designers can tweak styling without refactoring component logic. -

Inferno
React-like JavaScript library for building modern user interfaces
Inferno is an insanely fast, React-like library for building high-performance user interfaces on both the client and server. React-like API, concepts and component lifecycle events. Switch over easily with inferno-compat. One of the fastest front-end frameworks for rendering UI in the DOM, making 60 FPS on mobile possible. Isomorphic rendering on both client and server, along with fast-booting from server-side renders. Inferno doesn't have a fully synthetic event system like React does. Inferno has a partially synthetic event system, instead opting to only delegate certain events (such as `onClick`). Inferno doesn't support React Native. Inferno was only designed for the browser/server with the DOM in mind. Inferno doesn't support legacy string refs, use `createRef` or callback `ref` API. Inferno provides lifecycle events on functional components. This is a major win for people who prefer lightweight components rather than ES2015 classes. -

Introduction to Vue.js 3 Course
Workshop Materials for my Introduction to Vue.js Workshop
Introduction to Vue.js 3 Course houses the workshop materials for an “Introduction to Vue.js” course created by Sarah Drasner, originally delivered on Frontend Masters. The content covers essential Vue.js concepts such as directives, data rendering, methods, watchers, computed properties, components, slots, and the Composition API (for Vue 3), complemented with example code and exercises. Since the course was updated for Vue 3, the repo includes directories for both Vue 2 and Vue 3 resources, enabling learners to explore both versions depending on their work context. Also included are build setups (Vue CLI, Nuxt) and additional sections on animation and advanced topics like custom directives, making it a full learning path rather than just a quick tutorial. The README lists slide sets, exercise folders, solution folders and recommended tooling so that learners can clone the repo and follow along in their own time. -

JSVerbalExpressions
JavaScript Regular expressions made easy
VerbalExpressions is a JavaScript library that helps to construct difficult regular expressions. Methods have a return type of VerbalExpression except where mentioned otherwise. If there is no mention of a method’s parameters, it is to be assumed that it has none. VerEx is the function that is exported from within VerbalExpressions.js and is to be the first method in chains that describe verbal expressions. Construct and return a new instance of VerbalExpression. Used to support the new VerbalExpression() syntax in ES6 classes as mandated by the spec. You usually wouldn’t need to call VerEx().constructor(). This method will not be accessible from outside the source file since VerEx() returns an instance of the class rather than the class itself. sanitize is a static method on the VerbalExpression class. However, it is also exposed as VerEx().sanitize. Enabling control multi-line matching would cause the expression to not look for matches beyond the first line. -

Keen UI
A lightweight Vue.js UI library with a simple API
Keen UI is a Vue.js UI library with a simple API, inspired by Google's Material Design. Keen UI is not a CSS framework. Therefore, it doesn't include styles for a grid system, typography, etc. Instead, the focus is on interactive components that require Javascript. You should be able to use Keen UI with any page layout, structure, or CSS framework. -

Learning Prompt
Free prompt engineering online course
Learning-Prompt is a curated repository of prompts, techniques, and instructional patterns designed to help people construct better prompts for AI systems, including generation, reasoning, and debugging tasks. It collects examples of effective prompt formats, chains of thought, strategy scaffolds, and comparative methods that help yield consistent, high-quality results. The project also includes meta-guidance: reflections on prompt failures, tips for prompt tuning, ways to mitigate model bias or misinterpretation, and how to adapt prompts for different AI capabilities. Because prompt design is a skill under continuous iteration, the repo encourages contributions of new prompt recipes, evaluations, and domain-specific adaptations. It’s intended for educators, developers, and prompt engineers who want a living toolkit rather than static advice. Over time it serves as both a reference and playground for emergent prompt techniques. -

LemonadeJS
LemonadeJS is a 7KB reactive JavaScript micro-library
LemonadeJS is an ultra-lightweight, reactive JavaScript micro-library that makes building dynamic user interfaces simple and intuitive by providing two-way data binding and component reactivity without any external dependencies or build steps. At roughly 5–7 KB, it works directly in the browser or with bundlers like webpack, enabling developers to create reusable, reactive UI components using pure JavaScript, JSX, or TypeScript while avoiding heavy frameworks. Its core reactivity system tracks changes to component state and efficiently updates only the affected parts of the DOM, which improves performance for both small widgets and larger applications. The library also offers powerful template syntax and lifecycle hooks so you can manage state, effects, loops, and events in a clear and expressive way while keeping your code close to native JavaScript. -

List.js
Library for adding search, sort, filters and flexibility to tables
Tiny, invisible and simple, yet powerful and incredibly fast vanilla JavaScript that adds search, sort, filters and flexibility to plain HTML lists, tables, or anything. List.js can be used in three different ways. It can be on existing HTML, it can create it's own HTML or a combination of both methods. Works both lists, tables and almost anything else. E.g. <div>,<ul>,<table>, etc. Simple templating system that adds possibility to add, edit, remove items. Perfect library for adding search, sort, filters and flexibility to tables, lists and various HTML elements. Built to be invisible and work on existing HTML. Simple and invisible. Easy to apply to existing HTML. No dependencies. Fast, and tiny (5KB minified&gzip). It can handle thousands of items. It is easy to add search input and sort buttons with just a few classes and attributes in your HTML. ‘Automagical’ because List.js registers the event handlers, searches/sorts and updates the list for you. -

Map of GitHub
Inspirational Mapping
Map-of-GitHub is an inventive project that visually represents the global distribution of GitHub users and repositories on a map of the world, revealing geographic patterns and community concentrations across countries and cities. The project processes GitHub account metadata and GPS or location information (when available) to plot users’ locations and draw connections between communities, resulting in an exploratory visualization where density and network effects become instantly visible. Users can zoom in to explore hotspots like major metropolitan areas or zoom out to see global patterns of activity, making it both a data analytics tool and a piece of data art. The map highlights where developers live, where projects originate, and how open-source participation varies around the world, offering insights into the geography of technology culture and innovation. -

Masonry
A cascading grid layout plugin
Masonry is a JavaScript grid layout library. It works by placing elements in optimal position based on available vertical space, sort of like a mason fitting stones in a wall. You’ve probably seen it in use all over the Internet. All sizing and styling of items is handled by your own CSS. tem sizes can be set with percentages for responsive layouts. With the masonry layout mode, set percentage-width columnWidth with element sizing. Set percentPosition: true so item positions are likewise set with percentages to reduce adjustment transitions on window resize. Unloaded images can throw off Masonry layouts and cause item elements to overlap. imagesLoaded resolves this issue. imagesLoaded is a separate script you can download at imagesloaded.desandro.com. Or, initialize Masonry after all images have been loaded. -

Moment.js
Parse, validate, manipulate, and display dates in javascript
Moment is a JavaScript date and time library that simplifies parsing, formatting, arithmetic, and humanizing of dates. It supports many formats in input and output, internationalization (i18n), locale-based month/day names, relative time (for example, “3 days ago”), and chaining of operations (adding, subtracting, diffing). Developers often use it for calendar displays, scheduling, and manipulating times across time zones or daylight saving transitions. While it makes working with date strings convenient, moment maintains internal mutability, which has trade-offs with safety and chainability. Over time, newer alternatives with immutable and modular designs have emerged, but moment remains widely known and integrated in many legacy projects. Its comprehensive feature set and ease of use made it a standard for date-time handling in JavaScript for many years. -

Nock
HTTP server mocking and expectations library for Node.js
HTTP server mocking and expectations library for Node.js. Nock can be used to test modules that perform HTTP requests in isolation. For instance, if a module performs HTTP requests to a CouchDB server or makes HTTP requests to the Amazon API, you can test that module in isolation. Nock works by overriding Node's http.request function. Also, it overrides http.ClientRequest too to cover for modules that use it directly. -

React Projects
Collection of React example / tutorial projects
This repository is a collection of small-to-medium React applications that showcase practical patterns, from stateful widgets to multi-page interfaces. Each project is self-contained and demonstrates specific techniques—hooks for state and effects, context for global state, custom hooks for reuse, and reducer patterns for complex updates. The codebases include common UI tasks like forms, modals, lists, filtered search, and pagination, along with data fetching and basic routing where appropriate. Because every project focuses on a narrow set of concepts, learners can clone a single folder, run it, and grasp the idea without wading through a monolith. The examples are structured to be approachable yet idiomatic, encouraging good habits while staying close to what developers actually build. Over time, the collection functions as a portfolio of reference implementations that students and practitioners can adapt to new projects. -

React Toolbox
A set of React components implementing Google's Material Design
React Toolbox is a set of React components that implements Google Material Design specification. It's built on top of some the trendiest proposals like CSS Modules (written in SASS), Webpack and ES6. The library harmoniously integrates with your Webpack workflow and it's easily customizable and very flexible. Check our awesome documentation (which is built using React Toolbox) and try all the components with live examples. We've created a playground so you don't need to install anything to fall in love with our components, so fun! React Toolbox uses CSS Modules by default to import stylesheets written using PostCSS & postcss-preset-env features. In case you want to import the components already bundled with CSS, your module bundler should be able to require these PostCSS modules. Of course this is a set of React components so you should be familiar with React. If want to customize your components via themes, you may want to take a look to react-css-themr, used by React Toolbox. -

Resumable.js
Library for providing multiple uploads via the HTML5 File API
Resumable.js is a JavaScript library providing multiple simultaneous, stable and resumable uploads via the HTML5 File API. The library is designed to introduce fault-tolerance into the upload of large files through HTTP. This is done by splitting each file into small chunks. Then, whenever the upload of a chunk fails, uploading is retried until the procedure completes. This allows uploads to automatically resume uploading after a network connection is lost either locally or to the server. Additionally, it allows for users to pause, resume and even recover uploads without losing state because only the currently uploading chunks will be aborted, not the entire upload. Resumable.js does not have any external dependencies other than the HTML5 File API. This is relied on for the ability to chunk files into smaller pieces. Currently, this means that support is widely available in to Firefox 4+, Chrome 11+, Safari 6+ and Internet Explorer 10+. -
