AngleSharp: From Airplane Prototype to .NET Foundation Project

Описание и применение

AngleSharp – это модульный .NET‑библиотека, которая обеспечивает полноценный парсинг HTML, SVG, MathML, CSS и XML, ставшая популярной благодаря строгому соблюдению стандартов и активному сообществу.

Задача

Developers needed a reliable, spec‑conformant HTML/CSS/DOM parser for .NET without relying on browsers or regex hacks.

Результат

AngleSharp evolved from a solo prototype into a modular, community‑driven .NET library with hundreds of millions of downloads, enabling reliable HTML parsing and related tooling across the ecosystem.

Рабочий процесс

• 1. Identify need for a full HTML5 parser in .NET.
• 2. Start implementation on a flight using the HTML5 spec as reference.
• 3. Build core tokenizer, tree construction, and DOM APIs.
• 4. Iterate on edge cases and error handling to match browser behavior.
• 5. Publish initial code on GitHub and write a CodeProject article.
• 6. Engage community, accept contributions, and refactor for modularity (0.10 release).
• 7. Stabilize API, adopt semantic versioning, and release 1.0.
• 8. Expand ecosystem with satellite libraries (Css, Js, Xml, Io, Diffing, Wasm).
• 9. Maintain project under .NET Foundation and grow community.
• 10. Monitor adoption via NuGet downloads and community feedback.
