Month: 2026-01 Concise monthly summary focusing on key features, fixes, impact, and skills demonstrated. Key features delivered: - Spatial indexing in Editor: Introduced SpatialIndexManager using an R-tree (RBush) for efficient shape queries with per-page indexing. Initially exposed via the public API as editor.spatialIndex, including getShapeIdsInsideBounds(bounds) and getShapeIdsAtPoint(point, margin?). This system improves performance for viewport culling, selection, and erasing on canvases with many shapes. Also included incremental updates and upgraded RBush to v4.0.1. - Spatial index lifecycle and correctness: Addressed correctness of index updates when shapes are moved between pages; switched to an on-current-page check to upsert or remove shapes, preventing stale entries. - Release process stabilization: Stabilized release workflow and packaging by ensuring the VSCode extension .vsix is committed only after a successful publish, reducing partial state risk and aligning SDK release triggers with the workflow. - Sync stability workaround: Temporarily disable rate limiting in the sync-worker to avoid Cloudflare rate limit failures and maintain smooth operation while root causes are investigated. Major bugs fixed: - Correct spatial index removal for shapes moved between pages: fix ensures upsert/remove is based on current page state, eliminating lingering index entries. - Release workflow partial-state risk mitigations in VSCode extension publish path to ensure consistent releases. - Temporary Cloudflare rate-limit bypass in sync-worker to stabilize sync during incident assessment (safe revert path documented). Overall impact and accomplishments: - Performance and scalability: Spatial indexing significantly reduces expensive shape-iteration work and improves responsiveness on large canvases, enabling faster selection/eraser operations. - Reliability: Safer release process and predictable publish results reduce deployment risk and support smoother SDK releases. - Maintainability: Internalization work on spatial index indicates a push toward cleaner public API and clearer separation of concerns while preserving existing public hit-testing behavior. Technologies/skills demonstrated: - Spatial indexing with an R-tree (RBush), per-page indexing, and incremental updates. - TypeScript API design and evolution (public to internal exposure handling). - Release automation and pipeline hygiene (VSCode extension publish flow, .vsix handling). - Debugging strategy for edge cases in multi-page canvases and network rate-limit handling.
