@lernkit/tracker

Unified tracking interface for SCORM 1.2 / SCORM 2004 / cmi5 / xAPI with pluggable adapters.

Components call domain-level methods — setScore(0.9), setProgress(0.75), recordInteraction(...) — and the active adapter translates those into the wire format of the target standard. See ADR 0004.

Phase 0 status

This package ships the Tracker interface plus a NoopAdapter used for previews (Astro dev server, ?print=1, test runs). The real adapters land in later phases:

| Adapter | Phase | Standard | |---|---|---| | NoopAdapter | Phase 0 | no-op (dev preview) | | ScormAgainAdapter12 | Phase 1 | SCORM 1.2 | | ScormAgainAdapter2004 | Phase 3 | SCORM 2004 4th Ed | | Cmi5Adapter | Phase 3 | cmi5 | | XapiAdapter | Phase 3 | xAPI 2.0 / IEEE 9274.1.1 |

Usage (preview)

import { NoopAdapter, type Tracker } from '@lernkit/tracker';

const tracker: Tracker = new NoopAdapter();
await tracker.init();
await tracker.setProgress(0.5);
await tracker.setScore({ scaled: 0.9 });
await tracker.complete();
await tracker.pass();
await tracker.terminate();
