office-viewer

Architecture spike for a standalone, read-only browser-based Office Open XML viewer built on @silurus/ooxml.

Status

Milestone 2 (API Contract) is complete. The core custom element, <office-viewer>, now has a stable, documented public API covering source loading, lifecycle management, and format-specific navigation controls for DOCX, XLSX, and PPTX.

Next Steps

The focus shifts from defining the API surface to solidifying the integration points:

1. Implementing the DOCX Adapter: Scaffolding for src/viewers/docx-adapter.ts is required.
2. Testing: Initial unit tests for source normalization and format detection must be created.
3. Initialization: The main application entry point in src/index.ts must be updated to correctly initialize and use the component.

API Summary

The public API contract is now finalized and documented in src/viewers/adapter-types.ts. Key additions include:

• Format-specific methods: Added optional methods like goToPage?(), goToSheet?(), and goToSlide?() to OfficeViewerAdapter to expose format-specific interaction points.
• Core Methods: load(), reload(), destroy(), getSummary() remain the primary control points.
• Event System: Continues to dispatch granular events (pagechange, sheetchange, slidechange) to support advanced framework integration.
