Move shared type contracts from `contracts` to new `api-contracts` module in `compute/core` for clearer API boundaries. Remove legacy `contracts`, `pdf`, and `whisper` index files. Update all imports to use `api-contracts`. Refactor server job logic by replacing `parsePdfJob.ts` with modular `user-pdf-layout-job.ts` and `user-whisper-align-job.ts`, updating all relevant API routes and compute integration. This improves maintainability and separation of concerns across compute and server layers.
Add useOnboardingCoordinator hook and onboarding-state registry to manage
onboarding-related state such as privacy acceptance and first-visit tracking.
Refactor SettingsModal to utilize the new onboarding state abstractions,
removing legacy privacy gating logic and improving maintainability.
Includes unit tests for onboarding-state registry to ensure correctness.
Move TTS segment cache invalidation to a fire-and-forget promise after
document update to prevent cache errors from blocking parse readiness.
Log warnings for both cache invalidation failures and warnings, but do not
interrupt the main job flow. This improves job robustness and avoids
unnecessary failures due to cache issues.
Consolidate privacy acceptance checks into reusable hooks and callbacks within
SettingsModal. Replace scattered gating with a single entry point for opening
settings or changelog views, ensuring consistent enforcement. Update test
helpers to robustly dismiss onboarding and settings overlays by avoiding
state race conditions.
Enhance worker operation handling by adding detailed logging for operation
acceptance, reuse, replacement, and stale detection, including opKey hashes and
reasons for replacement. Remove the alignMutex from Whisper alignment logic to
simplify concurrency control and reduce unnecessary serialization of alignment
requests. These changes improve observability and throughput for alignment and
layout parsing jobs.
Introduce COMPUTE_NATS_REPLICAS environment variable to control the number of
replicas for JetStream streams and key-value buckets. Only values 1, 3, or 5
are accepted, defaulting to 1 for other inputs. Update worker server logic and
deployment documentation to describe and support this configuration.
Add lazy NATS connection lifecycle and idle disconnect logic to the worker,
enabling automatic disconnection after 120s of inactivity to support Railway
container sleep. Update deployment docs to describe this behavior, including
caveats and reconnection flow.
Allow '@openreader/compute-core/types' as a permitted subpath in ESLint
import rules. Update the lint message to reflect the new allowed subpath,
ensuring consistency with recent type centralization efforts.
Move and re-export all PDF parsing and TTS-related types from
@openreader/compute-core/types, eliminating local type duplication.
Update imports throughout the codebase to use the new centralized type
module. Remove obsolete worker-contract file and update tsconfig paths
and compute-core exports for the new types entry point. Refactor API
routes and job logic to use the new type imports and shared parse-state
healing utility. This streamlines type management and improves
consistency between compute and app layers.
Introduce automatic healing for stale PDF parse states in API routes. Add
`isDocumentParseStateStale` utility and use a shared `COMPUTE_OP_STALE_MS`
environment variable (with config getter) to control the stale window for both
worker op replacement and app-side parse-state healing. Update documentation and
environment variable references to reflect new config.
Enables automatic marking of stuck parses as failed, improving reliability and
retry behavior in distributed compute environments.
Update PDF viewer and document hook to improve parse status management:
- Set parseStatus to null on clear instead of 'pending' for accurate state
- Explicitly set initial parseStatus and reset parseProgress when loading a new document
- Adjust loader display logic to check for resolved parse status before showing expanded loader
Prevents UI inconsistencies and ensures parse progress is reflected correctly during document transitions.
- Replace static JSON imports with runtime manifest loading in pdf and whisper model modules for compatibility with ESM and bundlers
- Refactor Next.js config to clarify compute mode logic and improve worker bundling conditions
- Update test imports to use package entrypoints instead of relative paths
- Remove redundant whisper alignment/model tests now covered elsewhere or by integration
- No breaking changes to public API or model handling logic
Replace static timeout constants with functions that derive alignment and ffmpeg
decode timeouts from compute timeout config. This enables adaptive timeout
behavior based on runtime configuration, improving robustness under varying
resource constraints. Update error handling and internal APIs to propagate
timeout values accordingly.
Remove unused Node.js engine constraint from package.json for broader compatibility.
Remove unnecessary UI reload and modal interactions during audiobook export
cleanup to reduce flakiness under load. Set explicit timeout for long-running
MP3 export test to ensure consistent execution. These changes enhance test
stability and maintainability.
- Deleted mergeTextWithRegions.ts, LICENSE.txt, manifest.json, parsePdf.ts, renderPage.ts, runLayoutModel.ts, stitchCrossPageBlocks.ts, and types.ts as they are no longer needed.
- Updated unit tests to reflect new import paths from @openreader/compute-core.
- Adjusted tsconfig.json to include new paths for pdf-layout module.
Align COMPUTE_PDF_JOB_ATTEMPTS default value with new ONNX-based PDF layout
parsing approach by setting it to 1 in environment examples, worker config,
and deployment documentation. This reflects improved reliability and reduces
unnecessary retries for PDF processing jobs.
Standardize compute job concurrency configuration by introducing a shared
COMPUTE_JOB_CONCURRENCY setting, replacing separate PDF and Whisper concurrency
controls. Add cross-platform CPU core detection and thread budgeting utilities,
and update both ONNX model execution and concurrency limiters to use dynamic
thread allocation per job. Refactor environment variable docs and examples to
reflect unified concurrency management. Streamline PDF.js font path resolution
for improved reliability across environments.
Introduce idle and hard cap timeouts for PDF layout parsing in the compute worker,
ensuring long-running jobs are capped and progress is tracked with explicit
timeouts. Refactor NATS JetStream client initialization to use a configurable
API timeout. Update PDF viewer UI to treat parse state as 'pending' by default,
improving clarity during document preparation and parsing. Refine parse loader
labels and progress logic for more accurate user feedback.
Update compute worker to use separate environment variable for PDF job attempts
(`COMPUTE_PDF_JOB_ATTEMPTS`) and set Whisper job max deliveries to 1, clarifying
and separating retry logic between job types. Adjust `.env.example` and deployment
docs to comment out defaults and document new/renamed variables for advanced tuning.
In TTS segment ensure route, introduce explicit timeouts for Whisper alignment
operations, with configurable durations for local and worker modes, improving
robustness and error handling for long-running alignments.
Revise PDF viewer to introduce an explicit 'unknown' parse state and improve
loader and status messaging for better user clarity. Refactor Spinner to use
'currentColor' for border styling and simplify conditional rendering based on
className. Expand compute worker .env.example with explicit concurrency,
timeout, and job attempt variables for enhanced configuration transparency.
Enhance PDF parse loader transitions by introducing a delayed expansion for detailed progress, reducing UI flicker during parse-to-render handoff. Refactor PDFViewer to ensure document readiness is signaled only once per load, preventing redundant callbacks and improving synchronization between parsing and rendering states.
Introduce detailed progress reporting for PDF layout parsing, exposing phase and page-level updates to clients. Replace legacy parseStatus with a structured parseState field in the database schema, updating all relevant backend and API logic. Add SSE endpoint for real-time parse progress updates. Update client hooks and UI to reflect granular progress and improve user feedback during document parsing. Includes migration scripts and new parse-state utility module.
