Puck
Open source visual editor for building React drag-and-drop pages
Puck is an open source visual editor designed for React applications that enables developers to build customizable drag-and-drop page editing experiences. It allows teams to create their own page builders by defining React components that can be arranged and configured through a visual interface. Puck is component-based and configuration-driven, meaning developers specify how components render and which editable fields control their properties. Puck integrates directly into existing React environments and works well with frameworks such as Next.js, enabling developers to embed editing capabilities directly inside their applications. It operates with a structured data model that stores content as a JSON payload, allowing the same configuration to power both the editing interface and the production rendering of pages. This approach gives developers full ownership of their content data while avoiding vendor lock-in. -

Rawgraphs app
A web interface to create custom vector-based visualizations
Inspired by and built on top of open-source projects. RAWGraphs is open to the community for contributions. Almost 30 visual models to visualize quantities, hierarchies, and time series and find insights in your data. Even though RAWGraphs is a web app, the data you insert will be processed only by your web browser. Save your project, or export it as a vector or raster image. Edit it within your favorite software. RAWGraphs is an open source data visualization framework built with the goal of making the visual representation of complex data easy for everyone. Primarily conceived as a tool for designers and vis geeks, RAWGraphs aims at providing a missing link between spreadsheet applications (e.g. Microsoft Excel, Apple Numbers, OpenRefine) and vector graphics editors (e.g. Adobe Illustrator, Inkscape, Figma). The project, led and maintained by the DensityDesign Research Lab (Politecnico di Milano) was released publicly in 2013. -

RunJS
A JavaScript playground that auto-evaluates as you type
Explore and experiment with JavaScript and TypeScript, visualize your ideas and get instant feedback as you type. Exploring JavaScript has never been easier. Live feedback as you type, with per-line results, makes it super clear what your code is doing. With RunJS you have access to Node and Browser APIs, including full DOM access. This gives you a level of versatility that's not possible in a standard REPL or Chrome console. Babel and TypeScript support enables you to write modern, up-to-date syntax. NPM integration makes trying out new libraries quick and easy. RunJS is a JavaScript playground that auto-evaluates your code as you type and outputs the results to a console pane. TypeScript and modern JavaScript features are supported through Babel transpilation. Additionally, Node and browser APIs are available. -

SQLite compiled to JavaScript
A javascript library to run SQLite on the web
sql.js is a javascript SQL database. It allows you to create a relational database and query it entirely in the browser. You can try it in this online demo. It uses a virtual database file stored in memory, and thus doesn't persist the changes made to the database. However, it allows you to import any existing sqlite file, and to export the created database as a JavaScript typed array. sql.js uses emscripten to compile SQLite to webassembly (or to javascript code for compatibility with older browsers). It includes contributed math and string extension functions. sql.js can be used like any traditional JavaScript library. If you are building a native application in JavaScript (using Electron for instance), or are working in node.js, you will likely prefer to use a native binding of SQLite to JavaScript. A native binding will not only be faster because it will run native code, but it will also be able to work on database files directly instead of having to load the entire database. -

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. -

Shiptest
The Shiptest Codebase
Shiptest is an open source fork of Space Station 13 that replaces the traditional single-station gameplay with multiple player-controlled ships. Instead of being confined to one station, players can design, operate, and explore with their own ships in a shared space environment. The repository contains full source code, assets, and maps to host or develop servers. Shiptest introduces new mechanics around ship construction, navigation, and resource management, creating a sandbox that emphasizes exploration and collaboration. Its modular design allows for diverse playstyles, from engineering and trade to combat and survival. The project is actively updated by its community, pushing SS13 gameplay in a fresh, experimental direction. -

Space Desktop
This project was bootstrapped with Create React App
This project was bootstrapped with Create React App. If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project. Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own. You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it. -

SuperAgent
Ajax for Node.js and browsers (JS HTTP client)
SuperAgent is light-weight progressive ajax API crafted for flexibility, readability, and a low learning curve after being frustrated with many of the existing request APIs. It also works with Node.js! Small progressive client-side HTTP request library, and Node.js module with the same API, supporting many high-level HTTP client features. Browser-ready versions of this module are available via jsdelivr, unpkg, and also in the node_modules/superagent/dist folder in downloads of the superagent package. If you are using browserify, webpack, rollup, or another bundler, then you can follow the same usage as Node. SuperAgent is easily extended via plugins. The Node client supports making requests to Unix Domain Sockets. DELETE, HEAD, PATCH, POST, and PUT requests can also be used, simply change the method name. Absolute URLs can be used. In web browsers absolute URLs work only if the server implements CORS. -

SuperTest
Super-agent driven library for testing node.js HTTP servers
A super-agent driven library for testing node.js HTTP servers using a fluent API. The motivation with this module is to provide a high-level abstraction for testing HTTP, while still allowing you to drop down to the lower-level API provided by superagent. Install SuperTest as an npm module and save it to your package.json file as a development dependency. You may pass an http.Server, or a Function to request(), if the server is not already listening for connections then it is bound to an ephemeral port for you so there is no need to keep track of ports. One thing to note, is that superagent now sends any HTTP error (anything other than a 2XX response code) to the callback as the first argument if you do not add a status code expect (i.e. .expect(302)). Expectations are run in the order of definition. This characteristic can be used to modify the response body or headers before executing an assertion. -
