pjax
pushState + ajax = pjax
pjax loads html from your server into the current page without a full page load. It's ajax with real permalinks, page titles, and a working back button that fully degrades. Check the box to toggle pjax. Whenever the time changes, a full page load has happened. If the time doesn't change, no full page load has occurred. The idea is you can't tell the difference between pjax page loads and normal page loads. On complicated sites, browsing just "feels faster." pjax is a jQuery plugin that uses ajax and pushState to deliver a fast browsing experience with real permalinks, page titles, and a working back button. pjax works by fetching HTML from your server via ajax and replacing the content of a container element on your page with the loaded HTML. It then updates the current URL in the browser using pushState. -

pretty-quick
Get Pretty Quick
Runs Prettier on your changed files. Pre-commit mode. Under this flag only staged files will be formatted, and they will be re-staged after formatting. Partially staged files will not be re-staged after formatting and pretty-quick will exit with a non-zero exit code. The intent is to abort the git commit and allow the user to amend their selective staging to include formatting fixes. When not in staged pre-commit mode, use this flag to compare changes with the specified branch. Defaults to master (git) / default (hg) branch. Do not resolve prettier config when determining which files to format, just use standard set of supported file types & extensions prettier supports. This may be useful if you do not need any customization and see performance issues. Check that files are correctly formatted, but don't format them. This is useful on CI to verify that all changed files in the current branch were correctly formatted. -

pxer
Pixiv crawler userscript for downloading artwork and galleries easily
Pxer is an open source tool designed to help users collect and download artwork from the Pixiv illustration platform. It is implemented primarily in client-side JavaScript and runs directly in the browser through a userscript environment, allowing it to integrate seamlessly with Pixiv pages. Pxer provides functionality to crawl and gather images, artwork metadata, and other related content from supported Pixiv pages. It is designed to be accessible even for users who are not developers, emphasizing ease of use and quick setup through browser extensions such as Tampermonkey. Once installed, Pxer adds controls to compatible Pixiv pages so users can trigger batch retrieval of illustrations and related assets. It focuses on making it easier to obtain large collections of artworks from artists, bookmarks, rankings, and search results. Its browser-based approach means the tool can operate without requiring a standalone desktop application while still providing powerful scraping. -

react-big-calendar
gcal/outlook like calendar component
An events calendar component built for React and made for modern browsers (read: IE10+) and uses flexbox over the classic tables-ception approach. Styles can be found at: react-big-calendar/lib/css/react-big-calendar.css, and should be included on the page with the calendar component. Also make sure that your calendar's container element has a height, or the calendar won't be visible. Date internationalization and localization is hard and react-big-calendar doesn't even attempt to solve that problem. Instead you can use one of the many excellent solutions already out there, via adapters called "localizers". Big Calendar comes with two localizers for use with Globalize.js or Moment.js. Choose the localizer that best suits your needs, or write your own. Whatever you do, you'll need to set it up before you can use the calendar (you only need to set it up once). -

react-native-animatable
Set of animations and declarative transitions for React Native
Declarative transitions and animations for React Native. To animate things you must use the createAnimatableComponent composer similar to the Animated.createAnimatedComponent. The common components View, Text and Image are precomposed and exposed under the Animatable namespace. If you have your own component that you wish to animate, simply wrap it with a Animatable.View. To make looping animations simply set the iterationCount to infinite. Most animations except the attention seekers work best when setting direction to alternate. You can create your own simple transitions of a style property of your own choosing. The following example will increase the font size by 5 for every tap, all animated, all declarative! If you don't supply a duration property, a spring animation will be used. Transitions require StyleSheet.flatten available in React Native 0.15 or later. If you are running on anything lower, please polyfill as described under imperative usage. -

react-starter-kit
The best scaffolding for React development
This starter pack is designed to allow you to use a full set of the latest and coolest front-end technologies, all of which are configurable, feature-rich, code hot-loading based on webpack, css preprocessing using sass, unit testing, code coverage reporting, Code splitting and more. The main purpose of this project is to preserve as decisively as possible. The goal is not to follow this structure to complete your project, but to make front-end development more robust, simpler, and most importantly, happier. You can get all the features below! In the end, this project wouldn't be so robust without everyone's contributions. All relevant libraries are ready and waiting to be called at any time. The structure of this project uses fractal (irregular fractal: suitable for large projects), the grouping of methods is mainly by characteristics rather than file types. Note that this directory structure is only a guideline and does not have to be followed. -

react-window
React components for rendering large lists and tabular data
React window works by only rendering part of a large data set (just enough to fill the viewport). This helps address some common performance bottlenecks. It reduces the amount of work (and time) required to render the initial view and to process updates. It reduces the memory footprint by avoiding over-allocation of DOM nodes. react-window is a complete rewrite of react-virtualized. If react-window provides the functionality your project needs, it is strongly recommend that you use it instead of react-virtualized. However if you need features that only react-virtualized provides, you have two options. Use react-virtualized. (It's still widely used by a lot of successful projects!). Or, create a component that decorates one of the react-window primitives and adds the functionality you need. You may even want to release this component to NPM (as its own, standalone package)! -

realm by MongoDB
Realm is a mobile database, an alternative to SQLite key-value stores
Realm’s mobile database is an open-source, developer-friendly alternative to CoreData and SQLite. Start in minutes, port your app in hours, and save yourself weeks of work. Realm’s object-oriented data model is simple to learn, doesn’t need an ORM, and lets you write less code. Realm’s local database persists data on-disk, so apps work as well offline as they do online. Realm is fully-featured, lightweight, and efficiently uses memory, disk space, and battery life. Realm was built for mobile developers, with simplicity in mind. The idiomatic, object-oriented data model can save you thousands of lines of code. Realm’s live objects mean data updated anywhere is automatically updated everywhere. If you need to freeze elements of your data for Reactive frameworks, you can do that, too. -

rehype
HTML processor powered by plugins part of the @unifiedjs collective
rehype is a tool that transforms HTML with plugins. These plugins can inspect and change the HTML. You can use rehype on the server, the client, CLIs, deno, etc. rehype is an ecosystem of plugins that work with HTML as structured data, specifically ASTs (abstract syntax trees). ASTs make it easy for programs to deal with HTML. We call those programs plugins. Plugins inspect and change trees. You can use the many existing plugins or you can make your own. You can use rehype for many different things. unified is the core project that transforms content with ASTs. rehype adds support for HTML to unified. hast is the HTML AST that rehype uses. Depending on the input you have and output you want, you can use different parts of rehype. If the input is HTML, you can use rehype-parse with unified. If the output is HTML, you can use rehype-stringify with unified If both the input and output are HTML, you can use rehype on its own. -

sassdoc
Release the docs!
SassDoc is to Sass what JSDoc is to JavaScript: a documentation system to build pretty and powerful docs in the blink of an eye. SassDoc parses your source folder to grab documentation-specific comments. From there, it builds a data tree, that gets enhanced and filtered before being passed to the view. So you end up with a fully styled HTML document. Write SassDoc-compliant comments. The syntax is pretty close to JSDoc’s although we took some liberty with it. SassDoc comes with surprisingly few configurations in itself. Most of the configuration is brought by the theme. However, you don’t have to set up a configuration file in the theme package, that would be silly. SassDoc merges the configuration file you provide (or that is being automatically fetched) with the one from the theme. If an option is set in both files, the one you set yourself overrides the one from the theme. -

scroll-world
A skill that turn any brand into a scrollable 3D world
Scroll World is an agent skill for producing immersive landing pages that feel like one continuous camera flight through a generated 3D world. It works with Claude Code, Codex, and other systems that support the SKILL.md format. The workflow interviews the user about the brand, message, visual direction, and ordered sequence of scenes. It then uses Higgsfield to generate still images, scene-entry videos, and connector clips built from matching boundary frames. A portable JavaScript engine maps scrolling to video time, adds lazy loading, and blends seams between clips. Templates and batch scripts cover prompting, frame extraction, encoding, page setup, and optional background removal. The output is framework-agnostic and can be embedded in plain HTML, Next.js, Vue, or Python-served sites. -

security-audit
A coding-agent skill for multi-phase security audits
security-audit is a coding-agent skill for running structured security audits on software repositories. It organizes the audit into multiple phases so the agent does not simply search randomly for vulnerabilities. The workflow begins with reconnaissance, then moves into parallel hunting across attack classes such as injection, access control, business logic, cryptography, feature abuse, and chained attacks. Findings are then challenged through separate validation agents to reduce false positives. The skill produces human-readable reports, detailed finding traces, structured JSON output, and independent verification against the actual source code. Overall, it is designed to make AI-assisted security review more systematic, adversarial, and evidence-based. -

simpleParallax.js
Simple and tiny JavaScript library that adds parallax animations
simpleParallax.js is a very simple and tiny Vanilla JS library that adds parallax animations on any image. Where it may be laborious to get results through other plugins, simpleParallax.js stands out for its ease and its visual rendering. The parallax effect is directly applied to image tags, there is no need to use background images. -

simplebox.js
A simple, responsive lightbox plugin
simplebox.js is a lightweight lightbox plugin (~936 bytes) that is easy to modify or extend to fit your needs. This plugin is intended to be quick, responsive, and efficient. The idea behind this plugin was to make the process of setting up a lightbox painless. My experience with finding and setting up lightbox plugins has been pretty bad. The plugins I've come across almost always have too many features. simplebox.js is designed to have just one feature: lightboxing. It's responsive out of the box and allows only a few crucial settings. -
