* 🧹 chore: resolve imports due to rebase
* chore: Update model mocks in unit tests for consistency
- Consolidated model mock implementations across various test files to streamline setup and reduce redundancy.
- Removed duplicate mock definitions for `getMultiplier` and `getCacheMultiplier`, ensuring a unified approach in `recordCollectedUsage.spec.js`, `openai.spec.js`, `responses.unit.spec.js`, and `abortMiddleware.spec.js`.
- Enhanced clarity and maintainability of test files by aligning mock structures with the latest model updates.
* fix: Safeguard token credit checks in transaction tests
- Updated assertions in `transaction.spec.ts` to handle potential null values for `updatedBalance` by using optional chaining.
- Enhanced robustness of tests related to token credit calculations, ensuring they correctly account for scenarios where the balance may not be found.
* chore: transaction methods with bulk insert functionality
- Introduced `bulkInsertTransactions` method in `transaction.ts` to facilitate batch insertion of transaction documents.
- Updated test file `transactions.bulk-parity.spec.ts` to utilize new pricing function assignments and handle potential null values in calculations, improving test robustness.
- Refactored pricing function initialization for clarity and consistency.
* refactor: Enhance type definitions and introduce new utility functions for model matching
- Added `findMatchingPattern` and `matchModelName` utility functions to improve model name matching logic in transaction methods.
- Updated type definitions for `findMatchingPattern` to accept a more specific tokensMap structure, enhancing type safety.
- Refactored `dbMethods` initialization in `transactions.bulk-parity.spec.ts` to include the new utility functions, improving test clarity and functionality.
* refactor: Update database method imports and enhance transaction handling
- Refactored `abortMiddleware.js` to utilize centralized database methods for message handling and conversation retrieval, improving code consistency.
- Enhanced `bulkInsertTransactions` in `transaction.ts` to handle empty document arrays gracefully and added error logging for better debugging.
- Updated type definitions in `transactions.ts` to enforce stricter typing for token types, enhancing type safety across transaction methods.
- Improved test setup in `transactions.bulk-parity.spec.ts` by refining pricing function assignments and ensuring robust handling of potential null values.
* refactor: Update database method references and improve transaction multiplier handling
- Refactored `client.js` to update database method references for `bulkInsertTransactions` and `updateBalance`, ensuring consistency in method usage.
- Enhanced transaction multiplier calculations in `transaction.spec.ts` to provide fallback values for write and read multipliers, improving robustness in cost calculations across structured token spending tests.
* ✨ feat: Add support for OpenDocument MIME types in file configuration
Updated the applicationMimeTypes regex to include support for OASIS OpenDocument formats, enhancing the file type recognition capabilities of the data provider.
* feat: document processing with OpenDocument support
Added support for OpenDocument Spreadsheet (ODS) MIME type in the file processing service and updated the document parser to handle ODS files. Included tests to verify correct parsing of ODS documents and updated file configuration to recognize OpenDocument formats.
* refactor: Enhance document processing to support additional Excel MIME types
Updated the document processing logic to utilize a regex for matching Excel MIME types, improving flexibility in handling various Excel file formats. Added tests to ensure correct parsing of new MIME types, including multiple Excel variants and OpenDocument formats. Adjusted file configuration to include these MIME types for better recognition in the file processing service.
* feat: Add support for additional OpenDocument MIME types in file processing
Enhanced the document processing service to support ODT, ODP, and ODG MIME types. Updated tests to verify correct routing through the OCR strategy for these new formats. Adjusted documentation to reflect changes in handled MIME types for improved clarity.
* feat: Added "document parser" OCR strategy
The document parser uses libraries to parse the text out of known document types.
This lets LibreChat handle some complex document types without having to use a
secondary service (like Mistral or standing up a RAG API server).
To enable the document parser, set the ocr strategy to "document_parser" in
librechat.yaml.
We now support:
- PDFs using pdfjs
- DOCX using mammoth
- XLS/XLSX using SheetJS
(The associated packages were also added to the project.)
* fix: applied Copilot code review suggestions
- Properly calculate length of text based on UTF8.
- Avoid issues with loading / blocking PDF parsing.
* fix: improved docs on parseDocument()
* chore: move to packages/api for TS support
* refactor: make document processing the default ocr strategy
- Introduced support for additional document types in the OCR strategy, including PDF, DOCX, and XLS/XLSX.
- Updated the file upload handling to dynamically select the appropriate parsing strategy based on the file type.
- Refactored the document parsing functions to use asynchronous imports for improved performance and maintainability.
* test: add unit tests for processAgentFileUpload functionality
- Introduced a new test suite for the processAgentFileUpload function in process.spec.js.
- Implemented various test cases to validate OCR strategy selection based on file types, including PDF, DOCX, XLSX, and XLS.
- Mocked dependencies to ensure isolated testing of file upload handling and strategy selection logic.
- Enhanced coverage for scenarios involving OCR capability checks and default strategy fallbacks.
* chore: update pdfjs-dist version and enhance document parsing tests
- Bumped pdfjs-dist dependency to version 5.4.624 in both api and packages/api.
- Refactored document parsing tests to use 'originalname' instead of 'filename' for file objects.
- Added a new test case for parsing XLS files to improve coverage of document types supported by the parser.
- Introduced a sample XLS file for testing purposes.
* feat: enforce text size limit and improve OCR fallback handling in processAgentFileUpload
- Added a check to ensure extracted text does not exceed the 15MB storage limit, throwing an error if it does.
- Refactored the OCR handling logic to improve fallback behavior when the configured OCR fails, ensuring a more robust document processing flow.
- Enhanced unit tests to cover scenarios for oversized text and fallback mechanisms, ensuring proper error handling and functionality.
* fix: correct OCR URL construction in performOCR function
- Updated the OCR URL construction to ensure it correctly appends '/ocr' to the base URL if not already present, improving the reliability of the OCR request.
