- Move TTS provider resolution and voice-fetch logic into shared catalog and make
remote fetches more resilient (timeouts, abort handling, baseUrl normalization,
treat explicit empty custom-openai responses as valid).
- Add continuation guard to TTS feature set and update API voices endpoint error
logging to better surface auth/session failures.
- Extract and stabilize ebook pipeline and epub adapter:
- Cache prepared EPUB chapters to avoid repeated parsing and handle missing/empty
chapter titles safely.
- Fail early when created chapter lacks a bookId.
- Improve config/preferences handling:
- Replace JSON stringify comparisons with a deepEqual utility to compare defaults.
- Tighten ConfigContext effect dependencies and consolidate synced preference
queuing logic to include additional keys.
- Harden end-to-end test helpers and unit tests:
- Make settings dialog dismissal deterministic (use Enter/Escape and explicit
visibility/enabled checks) and simplify upload retry behavior.
- Add unit test to ensure custom-openai empty voice lists are preserved.
Why: Reduce runtime and test flakiness, centralize TTS logic for easier maintenance,
and make EPUB processing and preference diffing more robust. Breaking changes: none.
- Introduce a shared tts-provider-catalog to centralize provider/model/voice defaults
and feature flags (supportsTtsInstructions, providerSupportsCustomModel, resolveProviderModels,
getDefaultVoices, etc.). Replace ad-hoc provider logic across server and client with catalog calls.
- Replace inline voice/model UI logic in SettingsModal, AudiobookExportModal, TTSContext,
generate server code, and voice hook to use catalog helpers (resolveTtsSettingsViewModel,
supportsTtsInstructions, getDefaultVoices).
- Extract audiobook generation responsibilities into a small client-side pipeline:
- Add createEpubAudiobookSourceAdapter and createPdfAudiobookSourceAdapter adapter modules
to prepare chapters from EPUB/PDF sources.
- Add runAudiobookGeneration and regenerateAudiobookChapter pipeline functions to handle
chapter preparation, progress tracking, request header construction, and retry/abort behavior.
- Wire adapters/pipeline into EPUBContext and PDFContext to simplify and centralize audiobook flow.
- Move config preference helpers out of ConfigContext into dedicated client modules:
- buildSyncedPreferencePatch (lib/client/config/preferences.ts)
- applyConfigUpdate and getVoicePreferenceKey (lib/client/config/updates.ts)
- Use these helpers in ConfigContext to keep update logic small and testable.
- Add TTS settings view model resolver (lib/client/settings/tts-settings.ts) and tests
for the tts-provider catalog and config helpers (tests/unit/tts-provider-catalog.spec.ts).
- Minor usages updated: AudiobookExportModal, SettingsModal, useVoiceManagement, TTSContext,
server tts generation, and various context files to consume the new modules.
Why: Reduce duplication, improve testability, and separate concerns for provider metadata,
UI view-model logic, and audiobook generation flow. Breaking changes: none.
- Removed unused imports and types from TTS route.
- Consolidated TTS buffer generation logic into a new module.
- Implemented caching for TTS audio buffers using LRU cache.
- Updated TTS request handling to support instructions for specific models.
- Refactored audiobook chapter creation to use new TTS generation logic.
- Simplified error handling and response management in TTS API.
- Enhanced client-side logic to manage TTS requests and retries.
- Updated types to reflect changes in TTS request payload structure.
