Cheerio is an HTML and XML parsing library and server-side DOM implementation. It functions as a markup manipulation tool and CSS selector engine, allowing users to parse, query, and modify HTML or XML documents in non-browser environments. The project provides a DOM-like tree representation of markup strings, enabling programmatic addition, removal, and modification of elements and attributes. It features a prototype-based plugin system that allows the extension of core functionality by adding custom methods to the document prototype. The library covers a broad range of capabilities includi

Lexical is a modular rich text editor framework used to build extensible web-based editors. It functions as a state-driven content editor that maintains a serializable, immutable snapshot of document content to ensure predictable updates and accessibility compliance. The framework is distinguished by its plugin-based architecture and customizable node framework, which allow developers to extend editor behavior through specialized content nodes and encapsulated runtime logic. It also includes a collaborative editing engine capable of synchronizing document state across multiple clients in real

This project is a vanilla JavaScript reference guide and implementation collection designed to replace legacy libraries with native browser patterns. It provides a set of native JavaScript patterns for selecting, modifying, and navigating HTML elements, alongside a web API implementation guide for handling events and styles. The project serves as a reference for implementing asynchronous JavaScript patterns using native promises and fetch for remote data and background tasks. It also includes a client-side utility collection for performing data transformations, type validation, and element me

This project provides an integration of Tree-sitter into the Neovim editor to enable structural code analysis. It serves as a framework for structural code navigation, context-aware syntax highlighting, and the management of language-specific parsers. The system distinguishes itself through a multi-language injection handler that identifies and parses embedded languages within a single document. It uses a dedicated parser manager to install, update, and remove grammar definitions and their associated query files. The tool covers several capability areas including incremental text selection,

AngleSharp ist ein HTML5-DOM-Parser und Web-Scraping-Framework, das entwickelt wurde, um HTML5-, SVG- und MathML-Dokumente in ein W3C-konformes Document Object Model zu parsen. Es fungiert als programmatischer HTML-Generator und CSS-Selektor-Engine zum Abfragen und Lokalisieren spezifischer Elemente innerhalb eines DOM. Das Projekt bietet Tools zur Simulation von Browserumgebungen, um Web-Interaktionen zu automatisieren, URLs zu navigieren und Formulare abzusenden. Es enthält einen dedizierten HTML- und CSS-Minifier, um die Dateigröße von Web-Assets durch Entfernen unnötiger Zeichen zu reduzieren. Die Bibliothek unterstützt HTML-DOM-Manipulation und die Extraktion strukturierter Daten von Websites. Sie handhabt die Transformation von Markup durch eine Parsing-Pipeline, die spezifikationsgesteuerte Fehlerbehebung und hierarchische Dokumentenkonstruktion umfasst.

Ark is a headless UI component library that delivers accessible, cross-framework primitives with behavior governed by finite state machines. It provides unstyled components that encapsulate logic and accessibility — including full keyboard navigation, focus management, and WAI-ARIA support — while leaving visual styling entirely to the consumer. Components expose scoped data attributes for CSS targeting and use state machines to produce predictable, testable interactive behavior across every state transition. The library distinguishes itself through a state propagation model that distributes

Sprint ist eine leichtgewichtige Bibliothek für DOM-Manipulation und Event-Handling. Sie bietet einen minimalen Satz an Dienstprogrammen zum Auswählen, Modifizieren und Durchlaufen von Elementen innerhalb des Browser-Document-Object-Models (DOM). Die Bibliothek nutzt eine Selektor-Engine, um spezifische Dokumentknoten mittels CSS-ähnlicher Muster und Positionsindizes zu isolieren. Sie kapselt rohe DOM-Elemente innerhalb eines Wrapper-Objekts, um eine konsistente API für die Aktualisierung von Elementattributen, Stilen und Inhalten bereitzustellen. Das Toolset deckt das Browser-Event-Management zum Anhängen und Entfernen von Interaktions-Handlern sowie die Navigation im Dokumentenbaum ab, um verwandte Knoten über Eltern-, Kind- und Geschwisterbeziehungen zu lokalisieren.
