Axis v0.2.0 introduces the first traceability and query capabilities built on top of the EPCIS domain model established in v0.1.

This release expands Axis from a strongly typed EPCIS modeling library into the foundation of a traceability engine.

Highlights

Query APIs

Developers can now fluently search and filter EPCIS event collections.

Features include:

  • EventCollection
  • Event filtering
  • EPC discovery
  • Event lookup by EPC
  • Collection traversal

EPC Collections

Axis now includes a dedicated EpcCollection type for working with EPC identifiers as first-class objects.

Features include:

  • EPC aggregation
  • Unique EPC discovery
  • Collection operations

Trace APIs

Axis introduces the first generation of traceability APIs.

New components:

  • Trace
  • TraceNode
  • TraceGraph

These APIs establish the foundation for future genealogy and relationship analysis capabilities.

Graph Generation

Developers can now generate trace graphs directly from EPCIS documents.

Example:

const graph = document.buildTraceGraph();

This creates a graph representation of EPCs discovered within an EPCIS document and prepares the platform for future relationship traversal capabilities.

Developer Experience

Axis continues to emphasize:

  • EPCIS-first design
  • Strong TypeScript typing
  • Immutable domain objects
  • Fluent APIs
  • JSON serialization
  • Round-trip parsing

Quality

  • 91 automated tests
  • 100% passing
  • Full TypeScript support
  • MIT Licensed

Looking Ahead

The next release, v0.3.0 — Graph Intelligence, will introduce:

  • Parent traversal
  • Child traversal
  • Ancestor traversal
  • Descendant traversal
  • Root node detection
  • Leaf node detection
  • Path discovery
  • Relationship-aware trace graphs

Axis is being built to become the foundational TypeScript toolkit for EPCIS, traceability, genealogy, and supply-chain intelligence applications.
