This repository contains 'officeParser', a robust Node.js and browser library for parsing 12 office document formats (DOCX, PPTX, XLSX, ODT, ODP, ODS, PDF, RTF, CSV, MD, HTML, EPUB) into a unified abstract syntax tree (AST) and generating high-fidelity output in 9 formats (JSON, text, Markdown, HTML, CSV, RTF, PDF, EPUB, and RAG-focused chunks). It provides a first-class CLI (`npx officeparser`) and a programmatic API (`parseOffice()` → AST → `.to(format, config?)`), with extensive configuration for OCR, chunking strategies, security limits, and format-specific dialects. The architecture follows a strict pipeline: format-specific parsers normalize documents into `OfficeParserAST`, then format-agnostic generators produce the desired output, enabling cross-format conversion and round-trip fidelity. The codebase demonstrates high craftsmanship with reusable utility modules (sanitization, typed error/warning systems, lazy ZIP handling, MathML-to-LaTeX conversion) and a comprehensive test suite covering parser baselines, generator baselines, security injection tests, and exhaustively tested edge cases. It supports browser and Node runtimes via dual CJS/ESM packages and bundled builds, including slim variants that minimize dependencies for browser environments. Key data flows include document metadata extraction, attachment handling (images, charts), OCR via Tesseract.js, PDF generation via Puppeteer, and semantic chunking for LLM ingestion. External dependencies include `pdfjs-dist`, `tesseract.js`, `fflate`, `chart.js`, and `puppeteer` (optional). While the repository is actively maintained with recent commits and CI across multiple Node versions, it shows some technical drift: deprecated API fields remain documented alongside replacements, and large files (e.g., OpenOfficeParser.ts at ~1600 lines) increase maintenance complexity. The builder has addressed past packaging issues (webpack context-module) and maintains sophisticated browser shims. Overall, it is a production-grade document conversion toolkit with exceptional reusability in its core utilities and a clean separation between parsing and generation.
This repository is a comprehensive string validation and sanitization library for Node.js and browser environments. It provides a large collection of validator functions (e.g., isEmail, isURL, isMobilePhone, isCreditCard) and sanitizers (e.g., trim, escape, whitelist). The library is designed as a set of small, self-contained modules under src/lib/, each exporting a single function. The main entry point is src/index.js, which aggregates all validators and sanitizers into a single export. The library has no runtime dependencies and can be used both server-side and client-side (via a UMD bundle). It includes extensive locale-specific data for phone numbers, postal codes, tax IDs, etc., making it suitable for international validation. The architecture follows a consistent pattern: each validator imports assertString for type checking and optionally merge for options handling, then performs validation using regex or algorithmic checks. The library is actively maintained with frequent releases and a formal security threat model.
This is a Laravel package that integrates the HTMLPurifier library to sanitize and purify HTML input, primarily for XSS protection. It provides a service provider, a facade, a global helper function (`clean()`), and custom Eloquent casts (`CleanHtml`, `CleanHtmlInput`, `CleanHtmlOutput`) for automatic sanitization on model attributes. The core `Purifier` class wraps HTMLPurifier with Laravel's config and filesystem, supporting dynamic configuration, custom HTML definitions, and a non-string bypass option. The package is well-tested and supports Laravel 5.8 through 13.0, with active maintenance and low technical drift.
