Changelog

Bug Fixes

• Fix Windows UNC path handling (\\server\share...) in PathResolver and Document — base_dir is now correctly posixified (\\ → //) and .. segments are expanded; previously _expandPath silently fell back to returning the path unchanged because require() is not available in ESM modules
• Remove unused posixfy() alias on PathResolver (duplicate of posixify())

Improvements

• Add pluggable HTTP cache system (HttpCache, MemoryHttpCache, HttpCacheManager) activated by the cache-uri document attribute, mirroring Ruby’s open-uri/cached behaviour. When cache-uri is set, an ephemeral in-memory cache is used per conversion by default; register a custom HttpCache implementation via HttpCacheManager.setCache() for persistent or file-system-backed caching.
• Export HttpCache, MemoryHttpCache, and HttpCacheManager from the browser entry point (browser.js), keeping it in sync with index.js
• Align readSvgContents with the Ruby reference implementation by delegating entirely to node.readContents, removing the manual isUriish/normalizeSystemPath split
• Fix warnIfEmpty in AbstractNode#readContents — the empty-string check now correctly uses != null instead of a truthy guard, so a warning is emitted for empty local SVG assets
