Performance improvements: - Added nodeIndex Map for O(1) node lookups instead of O(n) array searches - Made resolvers tree-shakeable by replacing switch statement with const object mapping - Optimized resolveGraph from O(nΒ²) to O(n) by building index before resolveRootNode calls - Inlined deduplication logic to reduce separate passes through node arrays Technical changes: - Added nodeIndex Map to SchemaOrgGraph interface - Modified find() method to use Map with fallback to array search during first pass - Updated push() method to maintain nodeIndex when new nodes are added - Converted loadResolver() from switch statement to const object mapping - Combined deduplication and normalization passes in resolveGraph() - Inlined helper functions (groupBy, uniqueBy, merge) into graph.ts All existing tests pass with these optimizations.
Simplifications: - Extracted indexNode() helper to eliminate code duplication between push() and resolveGraph() - Simplified final normalization by replacing groupBy with inline sorting logic - Reduced push() from 18 lines to 7 lines - Reduced index building from 15 lines to 3 lines The code is now more maintainable and easier to understand while maintaining the same performance characteristics.

- Replaced defu's createDefu with custom merge function - Replaced ohash's hash with hashCode utility - Maintains same merge behavior with deduplication - All tests passing (477/477) - Bundle size: 237 kB (1 kB increase from inlined merge logic) This change aligns with the main branch removal of these dependencies while preserving all performance optimizations.
Removed ~70 lines of duplicated code by: - Exporting groupBy, uniqueBy, and merge from util.ts - Importing these in graph.ts instead of duplicating them - Main chunk reduced from 4.94 kB to 2.31 kB (-2.6 kB) Bundle remains 237 kB total but code is better organized with zero duplication. All tests passing (477/477).

Rework schema.org so tree shaking works, improved bundle size and more efficient javascript.
hashutils for an auto-incrementing count for the ids. Please test your schema.org implementation in rich results after updating.β Comparison Results
