Rhubarb
A WebSocket library optimized for multiplayer JS games
Rhubarb is a lightweight WebSocket library for multiplayer HTML5 games. It is originally designed to be used by the ROYGBIV Engine. However, it can be used outside of ROYGBIV as well. Javascript is slow, therefore we want to have as much main-process-power as we can in order to do game related calculations, graphics rendering and achieving 60 FPS. For multiplayer games achieving 60 FPS gets even more complicated given that transferring data over WebSockets is a slow operation. It also triggers GC activity by copying the transferred data (if JSON is the preferred way), which eventually slows down the main thread as well. -

Rill
Fast SQL-based BI tool for real-time dashboards and analytics
Rill is an operational BI tool that turns raw datasets into fast, interactive dashboards using SQL and a code-first approach. It helps data teams move from data lake to insight quickly, without the complexity of traditional BI systems. With an embedded in-memory database powered by DuckDB or ClickHouse, queries run in milliseconds, enabling real-time exploration and analysis. Rill supports local and remote data sources such as CSV, Parquet, S3, and GCS, making it flexible across environments. Its BI-as-code model combines SQL, YAML configuration, Git version control, and CLI tools, allowing teams to build, manage, and deploy analytics workflows efficiently. Automatic data profiling and responsive query updates help users understand datasets instantly. Interactive dashboards come with opinionated defaults, so teams can focus on insights instead of setup, while metrics layers standardize business logic for consistent reporting across dashboards, APIs, and AI systems. -

Rivet
Visual AI IDE for building agents with prompt chains and graphs
Rivet is an open source visual AI programming environment designed to help developers build complex AI agents using a node-based interface and prompt chaining workflows. It provides a desktop application that allows users to visually construct and debug AI logic as interconnected graphs, making it easier to manage sophisticated interactions between language models and external tools. Rivet also includes a TypeScript library that enables these visual graphs to be executed and integrated directly into applications, bridging the gap between prototyping and production use. Rivet supports multiple large language model providers and integrates with services such as embeddings and transcription systems, allowing developers to create richer AI-powered features. Its architecture emphasizes composability, where different components like prompts, APIs, and data processing steps can be combined into reusable pipelines. -

SPX
A simple & straight-to-the-point PHP profiling extension
SPX, which stands for Simple Profiling eXtension, is just another profiling extension for PHP. It differentiates itself from other similar extensions as being totally free and confined to your infrastructure (i.e. no data leaks to a SaaS). Very simple to use: just set an environment variable (command line) or switch on a radio button (web request) to profile your script. Thus, you are free of manually instrumenting your code (Ctrl-C a long running command line script is even supported). Using a dedicated browser extension or command line launcher. Multi metrics capable: 22 are currently supported (various time & memory metrics, included files, objects in use, I/O...). Able to collect data without losing context. For example Xhprof (and potentially its forks) aggregates data per caller / callee pairs, which implies the loss of the full call stack and forbids timeline or Flamegraph based analysis. -

Schema.DTS
JSON-LD TypeScript types for Schema vocabulary
The project provides a comprehensive set of TypeScript typings based on the Schema vocabulary, enabling developers to author JSON-LD structured data with strong type safety. It supplies both high-level discriminated unions and helper types to model contexts, graphs, and linked data relationships with clarity and accuracy. Usage examples demonstrate how one can import types like Person, WithContext, or Graph and compose JSON-LD objects in a way that aligns with semantic-web and knowledge-graph practices. The repository also contains a generator tool that can pull ontology definitions and emit TypeScript definitions in bulk, ensuring the typings stay up to date and maintain consistency. It supports scenarios such as nested objects, graphs of entities, and action types with input/output constraints, which makes it suitable for rich metadata authoring and linked-data workflows. While it is maintained by Google, it is not an officially supported Google product. -

Scotty.js
Deploy static websites and single page apps to AWS S3
Scotty.js is available on NPM. Install it as a global dependency to be able to use scotty command anywhere. Developing a single page app is hard. From the very beginning, you’ll need to make many decisions — decisions like picking a framework, setting the folder structure, configuring linter, and many others. Amazon offers something that can scale, a combination of Simple Storage Service (S3) for static website hosting and CloudFrontas a CDN is a cheap but scalable way to deliver your single page app. Although it takes some time to prepare both of those too, even more if you are not familiar with Amazon Web Services. The main idea behind Scotty is to deploy your static website or single page app to Amazon ecosystem with a single command. It will deploy your static website, set up CDN with HTTPS, and even copy the website URL to your clipboard in a minute or so, depending on your internet speed and the website/app size. -

Scribe.js
JavaScript OCR and text extraction for images and PDFs
Scribe.js is a JavaScript library that provides Optical Character Recognition (OCR) and text extraction capabilities for both images and PDF documents, aimed at developers who want to build OCR features directly into their applications. The library can take image files (such as PNG or JPEG) and recognize the text they contain, and it can also extract text from PDF files that either already contain text or are image-based scans, using modern web standards and WebAssembly under the hood. In addition to simple text extraction, Scribe.js supports writing or injecting a high-quality invisible text layer back into PDFs, effectively making them searchable and improving usability for indexing or accessibility. It is written in modern ECMAScript Modules (ESM), so it can be imported in both browser and Node.js environments without a build step, though browser usage requires same-origin hosting of the files. -

Semantic UI React
The Semantic-UI-React integration
jQuery is a DOM manipulation library. It reads from and writes to the DOM. React uses a virtual DOM (a JavaScript representation of the real DOM). React only writes patch updates to the DOM, but never reads from it. It is not feasible to keep real DOM manipulations in sync with React's virtual DOM. Because of this, all jQuery functionality has been re-implemented in React. Declarative APIs provide for robust features and prop validation. Control the rendered HTML tag, or render one component as another component. Extra props are passed to the component you are rendering as. Augmentation is powerful. You can compose component features and props without adding extra nested components. This is essential for working with MenuLinks and react-router. Shorthand props generate markup for you, making many use cases a breeze. All object props are spread on the child components. Components with repeating children accept arrays of plain objects. -

Sequelize
A promise-based multi SQL dialect Node.js ORM
Sequelize is a promise-based Node.js ORM for Postgres, MySQL, MariaDB, SQLite and Microsoft SQL Server. It features solid transaction support, relations, eager and lazy loading, read replication and more. Sequelize follows SEMVER. Supports Node v6 and above to use ES6 features. Sequelize v5 was released on March 13, 2019. Official TypeScript typings are now included. Sequelize can be used since the beginning in order to automate the creation of every table in your database. Models are the essence of Sequelize. A model is an abstraction that represents a table in your database. In Sequelize, it is a class that extends Model. The model tells Sequelize several things about the entity it represents, such as the name of the table in the database and which columns it has (and their data types). -

Serverless Offline
Emulate AWS λ and API Gateway locally
This Serverless plugin emulates AWS λ and API Gateway on your local machine to speed up your development cycles. To do so, it starts an HTTP server that handles the request's lifecycle like APIG does and invokes your handlers. Options passed on the command line override YAML options. List of available function names and their corresponding serverless.yml function keys are listed after the server starts. This is important if you use a custom naming scheme for your functions as serverless-offline will use your custom name. The left side is the function's key in your serverless.yml and the right side is the function name that is used to call the function externally such as aws-sdk. Once you run a function that boots up the Docker container, it'll look through the layers for that function, download them in order to your layers folder, and save a hash of your layers so it can be re-used in future. -

Serverless Webpack
Serverless plugin to bundle your lambdas with Webpack
A Serverless Framework plugin to build your lambda functions with Webpack. When enabled in your service configuration, functions are packaged and compiled individually, resulting in smaller Lambda packages that contain only the code and dependencies needed to run the function. This allows the plugin to fully utilize WebPack's Tree-Shaking optimization. Configuration possibilities range from zero-config to fully customizable. Support of serverless package, serverless deploy and serverless deploy function. Support of serverless invoke local and serverless invoke local --watch. Support of serverless run and serverless run --watch. Integrates with serverless-offline to simulate local API Gateway endpoints. Cleaned up configuration. You should now use a custom.webpack object to configure everything relevant for the plugin. The old configuration still works but will be removed in the next major release. -

Share.js
Share with one click to Weibo, QQ Space, QQ Friends, WeChat, Tencent
share.js is a lightweight social sharing library for adding one-click share buttons to web pages. It supports platforms such as Weibo, Qzone, QQ, WeChat, Tencent Weibo, Douban, Facebook, Twitter, LinkedIn, Google+, and Diandian. The project provides a front-end sharing solution based on social share URLs rather than a heavy backend service. It can be used with or without jQuery, making it flexible for older web projects and simple static pages. The maintainer notes that the project is no longer actively modernized, but its approach remains useful because social sharing often comes down to constructing platform-specific links. It is best suited as a compact reference or legacy-ready sharing component. -

SingleFileZ
Web Extension for Firefox/MS Edge and CLI tool
SingleFileZ is a fork of SingleFile that allows you to save a webpage as a self-extracting HTML file. This HTML file is also a valid ZIP file that contains the resources (images, fonts, stylesheets, and frames) of the saved page. This ZIP file can be unzipped on the filesystem in order, for example, to view the page in a browser that would not support pages saved with SingleFileZ. To open saved pages from the filesystem in a Chromium-based browser, SingleFileZ must be installed and the option "Allow access to file URLs" must be enabled in the details page of the extension. Otherwise, the browser must be started with the switch. To open saved pages from the filesystem in Safari, the option "Disable Local File Restrictions" must be selected in the "Develop" menu. SingleFileZ is available on Firefox, Chrome and Microsoft Edge. You can save web pages to HTML from the command line interface. -

Sizzle
A sizzlin' hot selector engine
A pure-JavaScript CSS selector engine designed to be easily dropped in to a host library. Browser support may differ between standalone Sizzle and libraries that include Sizzle. Please report issues on Sizzle's issue tracker, rather than the trackers for disparate libraries. In order to build Sizzle, you should have Node.js/npm latest and git 1.7 or later (earlier versions might work OK, but are not tested). For Windows you have to download and install git and Node.js. Mac OS users should install Homebrew. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js. Linux/BSD users should use their appropriate package managers to install git and Node.js, or build from source if you swing that way. Workarounds for Internet Explorer 6 are still in the code but the browser is no longer actively tested. Sizzle supports virtually all CSS 3 Selectors, including escaped selectors (.foo\+bar), Unicode selectors, and more. -

Store.js
Cross-browser storage for all use cases, used across the web
Store.js is a cross-browser JavaScript storage library for simple client-side key-value persistence. It provides a small API for common storage actions such as setting, getting, removing, and iterating over saved values. The library was created to smooth over browser differences and give developers a consistent way to store data without cookies or Flash. It can use mechanisms such as localStorage, globalStorage, and userData behavior depending on browser support. store.js also supports plugin-based storage extensions and extra functionality for broader use cases. Its main value is making browser storage easier, more reliable, and more portable across older and modern web environments.
