React Beautiful DnD
Beautiful and accessible drag and drop for lists with React
React Beautiful DnD is a drag-and-drop library for React that emphasizes fluid motion, accessibility, and natural constraints. It provides Draggable and Droppable primitives that manage state, sensors, and reordering logic for you, so you focus on rendering. Keyboard support, screen-reader announcements, and predictable focus handling make interactions accessible beyond the mouse. The library computes dimensions and movement carefully to avoid jank, including automatic scrolling and collision handling when lists overflow. It supports common patterns like reordering within a list, moving items between multiple lists, and integrating with virtualized lists. Clear lifecycle callbacks expose what changed during a drag so you can persist updates or trigger side effects reliably. -

React Rails
Integrate React.js with Rails views and controllers
React-Rails is a flexible tool to use React with Rails. If you use Jbuilder to pass a JSON string to react_component, make sure your JSON is a stringified hash, not an array. This is not the Rails default, you should add the root node yourself. React-Rails 2.4.x uses React 16+ which no longer has React Addons. Therefore the pre-bundled version of react no longer has an addons version, if you need addons still, there is the 2.3.1+ version of the gem that still has addons. React-Rails supports plenty of file extensions such as: .js, .jsx.js, .js.jsx, .es6.js, .coffee, etcetera! Sometimes this will cause a stumble when searching for filenames. The require.context inserted into packs/application.js is used to load components. The component name tells react-rails where to load the component. -

Reactive Extensions for JavaScript
An API for asynchronous programming with observable streams
An API for asynchronous programming with observable streams. The Observer pattern done right. ReactiveX is a combination of the best ideas from. The Observer pattern, the Iterator pattern, and functional programming. ReactiveX is everywhere, and it's meant for everything. Available for idiomatic Java, Scala, C#, C++, Clojure, JavaScript, Python, Groovy, JRuby, and others. Embrace ReactiveX's asynchronicity, enabling concurrency and implementation independence. Manipulate UI events and API responses, on the Web with RxJS, or on mobile with Rx.NET and RxJava. Avoid intricate stateful programs, using clean input/output functions over observable streams. ReactiveX's operators often reduce what was once an elaborate challenge into a few lines of code. Traditional try/catch is powerless for errors in asynchronous computations, but ReactiveX is equipped with proper mechanisms for handling errors. -

SVGR
Transform SVGs into React components
React supports SVG out of the box, it's simpler, easier and much more powerful to have components instead of SVG files. Wrapped in a React component, your SVG is inlined in the page and you can style it using CSS. SVGR differs from other library by its solid architecture. It uses svg-parser + Babel to transform SVG code into JavaScript code. A whole directory can be processed, all SVG files (matching .svg or .SVG) are transformed into React components. It is possible to target React Native using react-native-svg. SVGR exposes a Node API, you can create a custom script or build another tool based on SVGR. SVGR can be used as a webpack loader, this way you can import your SVG directly as a React Component. SVGR ships with a handful of customizable options, usable in both the CLI and API. Modify all SVG nodes with uppercase and use a specific template with react-native-svg imports. All unsupported nodes will be removed. -

Sajax
Simple Ajax with multiple backend implementations
Sajax is a cross-platform, cross-browser web scripting toolkit that makes it easy to expose functions in your code to JavaScript. You will find a folder for each platform that is currently supported. Please see individual documentation in each folder for specific errata. As of 0.13 a JavaScript implementation of JSON.stringify() has become a requirement when sending data for browsers that do not have this natively (IE8 or FF3.5). It is highly recommended to also include a JSON.parse() implementation for better security for the client, especially when handling data from other sites, json.parse.js is the implementation from JSON2, unfortunately, this breaks Safari 1.3.2 json_parse_state.js seems to be the most compatible but json_parse.js might also be worth checking out. -

Schism
A self-hosting Scheme to WebAssembly compiler
Schism is an experimental compiler that translates Scheme programs into WebAssembly, allowing Scheme code to execute in both browser environments and server platforms like Node.js. Developed initially by Google researchers, the project was designed to explore the intersection of functional programming and WebAssembly’s low-level efficiency. Schism supports a subset of the R6RS Scheme standard and is self-hosting, meaning that the compiler itself is written in and compiled by Schism. Its architecture demonstrates advanced compiler design techniques such as staged compilation and snapshot-based bootstrapping. The project focuses on leveraging WebAssembly’s experimental capabilities, including reference types and tail calls, to test the limits of language portability and runtime performance. Though no longer actively maintained, Schism remains a valuable example of how high-level languages can be mapped to WebAssembly and offers insights into language implementation. -

14
ScrollTrigger
Let your page react to scroll changes
The most basic usage of ScrollTrigger is to trigger classes based on the current scroll position. E.g. when an element enters the viewport, fade it in. You can add custom offsets per element, or set offsets on the viewport (e.g. always trigger after the element reaches 20% of the viewport) When using the callbacks ScrollTrigger becomes really powerful. You can run custom code when an element enters/becomes visible, and even return Promises to halt the trigger if the callback fails. This makes lazy loading images very easy. The easiest way to start is to create a new instance and add some triggers to it, with all default values. This will toggle the 'visible' class when the element comes into the viewport and toggles the 'invisible' class when it scrolls out of the viewport. Adding callbacks / different classes can be done globally, this becomes the default for all triggers you add, or you can specify custom configuration when adding a trigger. -

Shoestring
A lightweight, simple DOM utility made to run on a tight budget.
Shoestring is a lightweight, modular DOM framework intended for developers who need their code to download and run as fast as possible. It is intended to be "just enough" of a tool to efficently write maintainable cross-browser JavaScript. The API is modeled after jQuery but we intentionally implement a tiny subset of the API to cover only the methods we commonly need in our projects. Each feature is built as an optional extension to a minimal core so each can be removed from the production build (dependencies between extensions are rare). The selector engine delegates to modern browsers' native document.querySelectorAll (IE8) and addEventListener (IE9), which means it requires browsers that support those features. For projects that require deeper compatibility or a richer set of features, it is simple to swap in jQuery instead. As a rule, anything that works with Shoestring should work with jQuery, but not the converse. -
