- Extract database schema and migrations into @openreader/database
- Extract startup and orchestration scripts into @openreader/bootstrap
- Move compute-worker into packages/compute-worker
- Remove runtime dependency on drizzle-kit
- Update Dockerfile to deploy isolated packages without merging node_modules
- Removed deprecated functions related to document parsing and blob storage in blobstore.ts.
- Introduced new PDF rendering logic in pdf-preview-renderer.ts and pdf-preview-pdfjs-runtime.ts.
- Updated previews-render.ts to utilize the new PDF rendering functions.
- Refactored user-whisper-align-job.ts to use the compute-worker client for alignment requests.
- Enhanced artifact.ts and operation.ts to validate parsed PDF artifacts and resolve current PDF parses.
- Updated snapshot.ts to align with new worker operation types.
- Adjusted runtime-config.ts to check for compute-worker availability.
- Modified types in parsed-pdf.ts and tts.ts to reflect changes in the compute-worker protocol.
- Added unit tests for PDF artifact validation and compute-worker client contract.
- Removed obsolete pdf-op-key.vitest.spec.ts test file.
Introduce support for external compute worker mode (`COMPUTE_MODE=worker`) using a new `WorkerComputeBackend`. This enables offloading heavy ONNX Whisper alignment and PDF layout parsing to a standalone worker service (Redis + BullMQ), improving scalability and compatibility with serverless/limited environments.
- Add `@openreader/compute-core` as a shared package for ONNX inference and PDF parsing logic.
- Implement `WorkerComputeBackend` and worker contract/types for remote job execution.
- Update compute backend selection logic and remove previous worker mode guards.
- Extend `WhisperAlignInput` and `PdfLayoutInput` types to support object keys for remote data access.
- Refactor local compute backend to use `@openreader/compute-core` and support both buffer and object key inputs.
- Update job runner, TTS segment alignment, and PDF layout parsing flows to use new compute backend APIs.
- Add scripts, Docker workflow, and documentation for deploying and running the compute worker.
- Update environment variable docs and examples for worker mode, including storage requirements and configuration.
- Document published images and stack changes to reflect the new compute worker architecture.
BREAKING CHANGE: `COMPUTE_MODE=worker` now requires an external compute worker service and S3-compatible object storage. Embedded SeaweedFS (`weed mini`) is not supported in worker mode. See the new documentation for deployment and configuration details.
Update GitHub Actions workflows to latest action versions and improve pnpm usage by introducing per-package workspace configs. Add docs-site/pnpm-workspace.yaml and update Dockerfile/package.json for better monorepo support. Upgrade dependencies across main and docs-site packages for compatibility and security. Refine TypeScript types and hooks for improved type safety and maintainability.
Add support for building and publishing multi-architecture Docker images (amd64 and arm64) using a matrix strategy. Introduce a new 'prepare' job for metadata computation and a 'merge' job for creating manifest lists. Enable manual workflow dispatch with optional latest tagging. Improve caching and provenance handling for better efficiency and reliability.
