- digital-sign-pdf.test.ts: stub VITE_CORS_PROXY_URL and
VITE_CORS_PROXY_SECRET env vars for test isolation
- timestamp-node.test.ts: replace regex-only test with actual data()
method tests covering timestampPdf call, output filename suffix,
and error wrapping with TSA context
Test the timestampPdf() function using the real sample.pdf (SHA256 verified).
PdfSigner is mocked to avoid network calls while validating:
- Correct signdate/TSA URL passed to PdfSigner
- PDF bytes forwarded to signer.sign()
- Uint8Array returned from signed result
- Error propagation from TSA failures
- Multiple TSA URL support
- Original PDF bytes not mutated
- Handle Headers instance in TSA request detection (not just plain objects)
- Wrap timestampPdf with createCorsAwareFetch for OCSP/cert chain requests
- Pass 'success' type to showAlert on successful timestamp
- Add TSA URL context to timestamp error messages with cause
- Remove redundant Uint8Array wrapping in TimestampNode
Add document timestamping to the Secure PDF section using RFC 3161
protocol. Users can select from preset TSA servers (DigiCert, Sectigo,
SSL.com, Entrust, FreeTSA) or enter a custom TSA URL. No personal
certificate is required — only a cryptographic hash is sent to the server.
Key changes:
- Timestamp PDF page with TSA server selector, FAQ and SEO structured data
- timestampPdf() function with CORS proxy URL resolution
- TimestampNode for the workflow engine
- Tool entry in Secure PDF category + homepage i18n
- Built-in CORS proxy middleware for dev/preview
- Translations for all 16 languages
Tested with DigiCert, Sectigo and Entrust TSA servers. Timestamps are
verifiable in Adobe Acrobat (ETSI.RFC3161 SubFilter).
- Refactored OCR page recognition to utilize a configured Tesseract worker.
- Added functions to manage font URLs and asset filenames based on language.
- Implemented language availability checks and error handling for unsupported languages.
- Enhanced PDF workflow to display available OCR languages and handle user selections.
- Introduced utility functions for resolving Tesseract asset configurations.
- Added tests for OCR functionality, font loading, and Tesseract runtime behavior.
- Updated global types to include environment variables for Tesseract and font configurations.
- Added support for 'moved' and 'style-changed' change types in PDF comparison.
- Implemented category filters for changes, allowing users to filter by text, images, headers, annotations, formatting, and background.
- Introduced zoom functionality with buttons for zooming in, out, and resetting to default.
- Updated UI to reflect new change types and categories, including visual indicators for moved and style-changed items.
- Enhanced summary display to include counts for moved and style-changed changes.
- Refactored rendering logic to accommodate zoom levels and improve performance.
- Added tests for new change detection features and category assignments.
- Deleted the exportCompareHtmlReport function and its related imports.
- Introduced a dropdown menu for exporting comparison results as PDFs with multiple modes (split, alternating, left, right).
- Updated the comparison logic to utilize caching for page models and comparison results.
- Refactored rendering functions to improve code organization and maintainability.
- Enhanced UI elements for better user experience during PDF export.
- Refactored CompareState to import from a centralized type definition.
- Enhanced the compare-pdfs.html layout with improved styles for overlay and side-by-side modes.
- Added new CSS styles for various UI components including panels, buttons, and highlights.
- Implemented a new sidebar for displaying change summaries and filters.
- Created unit tests for text comparison logic, including diffing text runs and page pairing.
- Added tests for text normalization functions to ensure proper handling of punctuation and character normalization.
- TRANSLATION.md: Spanish example incorrectly referenced fr/ locale path instead of es/
- footer.html: Instagram and LinkedIn links were missing target=_blank and rel=noopener noreferrer, unlike the other social links
- README.md: air-gapped manual steps referenced pymupdf-wasm@0.11.14 but the current default is 0.11.16
