- Replaced LibDOM with a custom Zig-based DOM implementation named zigdom to address friction in event systems, Custom Elements, and ShadowDOM integration.
- The new implementation offers full control over memory, events, and future enhancements, with slight performance improvements.
- Used html5ever for HTML parsing, which was seamless and required minimal effort.
- Implemented V8 snapshots to reduce startup time by pre-registering types and functions.
- Developed zigdom with the aid of an AI coding agent (Claude), which proved effective for well-documented tasks like DOM implementation.
- The cohesive Zig-based codebase simplifies future feature additions and enhancements.
