Carbonium is a tiny (1KB) TypeScript library that provides a jQuery-like DOM manipulation utility using JavaScript's Proxy object. It wraps `querySelectorAll` results in a Proxy, allowing property access and method calls to be applied to all matched elements simultaneously. The library supports element creation from HTML strings, handles edge cases like `style`, `classList`, `relList`, array methods (`forEach`, `filter`, etc.), iterators, and empty lists. It has zero runtime dependencies and is published as an npm package with ES module and IIFE bundles. The code is well-structured, thoroughly tested with Playwright across Chromium and Firefox, and includes comprehensive TypeScript type definitions. While the last commit date appears anomalous (2026), the repository shows active maintenance through CI workflows, dependabot, and modern dependency versions.
