📄 Docflow

Docflow is a feature-complete PDF editing application that runs entirely in the browser. It provides professional-grade document viewing, annotation, and editing capabilities with a clean, dark-themed interface.

Why Docflow? Most PDF editors are either heavy desktop applications or limited web tools. Docflow combines the accessibility of a web app with the power of a desktop editor — all running client-side with zero server dependencies.

• Open PDF files via file picker, drag-and-drop, or recent files
• Multi-document workspace with tabbed interface
• Session persistence — automatically restore your workspace
• Autosave with configurable intervals

• Object selection, move, resize, and rotation
• Undo/redo with full command history
• Clipboard support (copy, cut, paste, duplicate)
• Layer ordering (bring to front, send to back)
• Property inspector panel
• Search within documents

• Export to PDF with overlay flattening
• Export to PNG and JPEG
• Custom page ranges
• Metadata preservation
• Compression optimization

• Full keyboard shortcut system
• Command palette (Ctrl+Shift+P)
• Ctrl+Tab document switching
• Tool shortcuts (V, H, T, I, R, D, U, S, P, E)

• Node.js >= 22.12.x
• pnpm >= 11.x (or use corepack enable && corepack install)

The project includes a packageManager field in package.json. If you have corepack enabled, the correct pnpm version will be selected automatically.

Design Philosophy:

• All mutations go through the CommandPipeline for full undo/redo
• Zustand selectors with shallow equality for minimal re-renders
• Canvas for PDF page rendering, DOM for overlay annotations
• All errors route through GlobalErrorManager for structured handling

Docflow is at v1.0.0-rc.1 (Release Candidate). The application is feature-complete and production-hardened:

• ✅ Zero TypeScript errors (strict mode)
• ✅ Zero as any casts in production code
• ✅ All console output production-guarded
• ✅ Comprehensive ARIA accessibility
• ✅ Structured error handling
• ✅ Production build succeeds
• ⚠️ Awaiting community testing before v1.0.0 stable

• Electron desktop shell not yet integrated
• No per-subsystem error boundaries (global only)
• Limited unit test coverage
• Bundle size exceeds 500kB (pdf.js worker)
• Some components lack full ARIA support

Contributions are welcome! Please see the Contributing Guide for details.

Before submitting a PR:

1. Run pnpm typecheck — must pass with zero errors
