JSON Forms
Customizable JSON Schema-based forms with React, Angular and Vue
JSON Forms is a declarative framework for efficiently building form-based web UIs. These UIs are targeted at entering, modifying and viewing data and are usually embedded within an application. Writing HTML templates and Javascript for data binding by hand is hard, especially in applications of reasonable size. Furthermore, a form is often more than just a collection of input fields and more advanced functionality is required, e.g. validation or conditional visibility. JSON Forms utilizes the capabilities of JSON and JSON schema and provides a simple and declarative way of describing forms. Forms are then rendered with a UI library or framework, e.g. React or Angular. -

OCRBase
MD/.JSON Document OCR and structured data extraction API
OCRBase is a self-hostable document OCR and structured extraction system built to turn PDFs into machine-usable outputs at scale, aiming to bridge the gap between raw text extraction and production-ready pipelines. Instead of treating OCR as a one-off script, it presents an API-driven workflow where documents are submitted as jobs and processed through a queue-based architecture that can handle high throughput. The core output is designed for downstream automation, producing structured results like JSON according to user-defined schemas while also providing readable formats like Markdown for human review or indexing. It includes real-time job progress updates via WebSockets, which makes it easier to integrate into UIs, dashboards, or ingestion systems where users need feedback on long-running document processing. -

html-pdf-chrome
HTML to PDF or image (jpeg, png, webp) converter via Chrome/Chromium
HTML to PDF or image (jpeg, png, webp) converter via Chrome/Chromium. This library is NOT meant to accept untrusted user input. Doing so may have serious security risks such as Server-Side Request Forgery (SSRF). If you run into CORS issues, try using the --disable-web-security Chrome flag, either when you start Chrome externally, or in options.chromeFlags. This option should only be used if you fully trust the code you are executing during a print job. It is strongly recommended that you keep Chrome running side-by-side with Node.js. There is significant overhead starting up Chrome for each PDF generation which can be easily avoided. By default, pages are saved as a PDF. To save as a screenshot instead, supply screenshotOptions. You can optionally provide an HTML template for a custom header and/or footer. There are a few CompletionTrigger types that wait for something to occur before triggering PDF printing. -

tinypdf
Minimal PDF creation library
tinypdf is a minimal, zero-dependency PDF generation library that focuses on the core “put content on a page” use case while intentionally skipping heavyweight features. It is designed to be extremely small and approachable, making it a good fit when you want to generate real PDFs in Node/TypeScript without pulling in a large toolkit. The library supports essential primitives like writing text, drawing basic shapes, and placing JPEG images, which covers common needs such as invoices, receipts, tickets, and simple reports. It also supports clickable links so generated documents can include interactive URLs, and it can create multi-page documents with custom page sizes. A notable convenience is built-in markdown-to-PDF conversion for common structures like headers and lists, letting you go from formatted text to a PDF layout quickly. -

visx
Visualization components
visx a collection of expressive, low-level visualization primitives for React. At Airbnb, we made it a goal to unify our visualization stack across the company and in the process, we created a new project that brings together the power of D3 with the joy of React. visx is split into multiple packages. Start small and use only what you need. Bring your own state management, animation library, or CSS-in-JS solution. Odds are good your React app already has an opinion on how animation, theming, or styling is done. visx is careful not to add another one and integrates with all of them. As you start using visualization primitives, you’ll end up building your own charting library that’s optimized for your use case. You’re in control. And most importantly, it’s just React. If you know React, you can make visualizations. It’s all the same standard APIs and familiar patterns. visx should feel at home in any React codebase. -

Express Zod API
A Typescript library to help you get an API server up and running
Start your API server with I/O schema validation and custom middlewares in minutes. I made this library because of the often repetitive tasks of starting a web server API with the need to validate input data. It integrates and provides the capabilities of popular web servers, logger, validation, and document solutions. Therefore, many basic tasks can be accomplished faster and easier. -

Formly
JSON powered dynamic forms for Angular
Formly is a dynamic (JSON-powered) form library for Angular that brings unmatched maintainability to your application's forms. Easy to extend with custom field type, validation, wrapper and extension. Every developer that’s using Angular to build cool web applications knows forms are among the most common things to build. We are building by hand with all the tools Angular gives us. NGX Formly was built as an open-source project, which you can find on GitHub. The tool lets you create forms based on a JSON structure. This makes it super easy and fast to build small and advanced forms in no time. It’s no problem when you use Angular with Material, Bootstrap, Ionic, PrimeNG, Kendo, and NativeScript. They have a plugin for all of them. We can give the select options manually to the select or via a defined enum . In order to get all the information from the enum, we have to store them in the ProductTypeNames which output an Array from the enum . -

JsonDB
A simple "database" that use JSON file for Node.JS.
JsonDB is now using the concept of async/await for all its calls since we read from the database file on demand and depending on how the database is configured, we might write at each push. The module stores the data using JavaScript Object directly into a JSON file. You can easily traverse the data to directly reach the desired property using the DataPath. The principle of DataPath is the same as XMLPath. -

RSC Explorer
A tool for people curious about the React Server Components protocol
RSC Explorer is an educational, experiment-friendly tool for understanding the React Server Components (RSC) protocol by making the streaming process visible and inspectable. It runs both the “server” and “client” sides of RSC in the browser, removing the need to set up a full backend just to learn how the protocol behaves. The core experience is the ability to step through the RSC stream incrementally, seeing what data arrives at each moment and how that data maps to the React tree being constructed. It includes a set of curated examples that demonstrate how server and client features can interoperate, helping you develop intuition for boundaries, references, and progressive rendering. This makes it useful for educators, workshop leaders, and engineers who want to demystify RSC mechanics without relying on framework-specific abstractions. In practice, it functions like a “packet analyzer” for RSC, turning a normally opaque stream into something you can study and explain. -

htmlparser2
The fast & forgiving HTML and XML parser
The fast & forgiving HTML and XML parser. htmlparser2 is the fastest HTML parser, and takes some shortcuts to get there. If you need strict HTML spec compliance, have a look at parse5. htmlparser2 itself provides a callback interface that allows the consumption of documents with minimal allocations. While the Parser interface closely resembles Node.js streams, it’s not a 100% match. Use the WritableStream interface to process a streaming input. -

Angular Flex-Layout
Provides HTML UI layout for Angular applications
Angular Flex Layout provides a sophisticated layout API using Flexbox CSS + mediaQuery. This module provides Angular developers with component layout features using a custom Layout API, mediaQuery observables, and injected DOM flexbox-2016 CSS stylings. The Flex Layout engine intelligently automates the process of applying appropriate Flexbox CSS to browser view hierarchies. This automation also addresses many of the complexities and workarounds encountered with the traditional, manual, CSS-only application of box CSS. The real power of Flex Layout, however, is its responsive engine. The Responsive API enables developers to easily specify different layouts, sizing, visibilities for different viewport sizes and display devices. -

BSON parser
BSON Parser for node and browser
BSON parser is the core JavaScript implementation of BSON (Binary JSON), the data format used by MongoDB to represent documents on the wire and in storage. It provides encoding and decoding capabilities so JavaScript environments like Node.js and browsers can serialize rich data structures (including types not native to JSON) into the compact, efficient BSON binary representation used by MongoDB drivers and servers. Value types such as ObjectId, Binary, UTC datetime, Decimal128, and Long are provided as first-class objects, enabling precise representation of data that would otherwise be lossy or awkward in plain JSON. js-bson is designed for performance, with optimized algorithms for reading and writing binary data, minimizing overhead in database operations. Because it’s a foundational building block for MongoDB drivers in JavaScript, the library ensures consistency and compatibility between client applications and the MongoDB server. -

Lume
Create 3D web applications with HTML, bring a new depth to your DOM
A toolkit that simplifies the creation of rich and interactive 2D or 3D experiences. LUME is composed of several packages that can be used individually, or together as a whole. HTML elements for easily defining rich and interactive 2D or 3D applications powered by CSS3D, WebGL, or both mixed together. This is a web component system that allows you to create new, fast, and performant HTML elements in a simple way. It provides the foundation for LUME's HTML elements and a standard pattern for building new elements that extend the features of LUME. Augment HTML elements with features called "behaviors" that are similar to custom elements: each behavior is defined as a class that has the same lifecycle methods as custom elements. The difference is that an unlimited number of behaviors can be associated with an element. -

Manfred Awesomic CV
Manfred Awesomic CV
The MAC (or Manfred Awesomic CV) is a(nother) naive attempt to create a standard open-source format to define and share CVs. The format is defined as a JSON Schema to validate CVs stored as JSON files. There are A LOT of CV formats, and some of them are a nice try to define a universal CV format, but we think that a CV should include not only what candidates are or know but also what they are interested in and what they want to become. Like most open-source projects, the first use case was found in the company where the first contributors worked. Manfred is committed to the idea that every person should keep control over their personal and professional data. This means that they should be able to export their data from any platform in a machine-readable format with a Model Definition to process that data efficiently. This is how the MAC was born.
