TTRPG Manager

A local-first campaign manager for D&D 5e and Pathfinder 2e, built for both Game Masters and players. Runs entirely in the browser (installable as a PWA) — your data lives in IndexedDB on your device; no account, no server.

Features (MVP)

• Campaigns — create per-system campaigns; deleting one cascades to all its data.
• Characters — 5e/PF2e sheets with live derived stats: ability modifiers, proficiency, skills, saves, AC, initiative, HP (with damage/heal/temp). Autosaves.
• Combat tracker — initiative order, round/turn tracking, conditions, HP, and add/remove/reorder mid-fight without ever corrupting whose turn it is.
• Dice — full notation (2d6+3, 4d6kh3), advantage/disadvantage, seedable RNG, per-campaign roll history.
• Compendium — searchable SRD bestiary, spells, and magic items. Add any monster straight into the open encounter.

Tech

• React 19 + TypeScript (strict) + Vite
• TanStack Router · Zustand · Zod · Dexie (IndexedDB) · Tailwind v4 · Fuse.js
• Vitest (unit) + Playwright (e2e), PWA via vite-plugin-pwa

Architecture

src/
  lib/
    rules/        # game-system abstraction — 5e & pf2e behind one RulesSystem interface
    combat/       # pure, tested turn-order + HP engine
    dice/         # notation parser + roller
    db/           # Dexie schema + repositories (cascade deletes, validation on write)
    schemas/      # Zod entity schemas — every number rejects NaN/Infinity
    compendium/   # lazy SRD data loaders (code-split out of the main bundle)
  features/       # campaigns, characters, combat, dice, compendium (UI)
  components/ui/  # design-system primitives
  data/srd/       # SRD JSON (Open5e + MPMB); regenerate with scripts/fetch_data.py

The rules layer means features never branch on if (system === '5e'); they call the RulesSystem interface, so adding a system is a self-contained module.

Development

bun install
bun run dev          # dev server at http://localhost:5173
bun run test         # unit tests (vitest)
bun run test:e2e     # end-to-end (playwright)
bun run build        # typecheck + production build
bun run lint

Roadmap

Notes/journal, maps with fog of war, encounter/loot builders, a shared player view, PF2e compendium data, and an optional sync backend for real-time tables.

History

This is a from-scratch rebuild. The previous implementation (deleted) had ~135 documented bugs and no version control; its bug report is kept at docs/OLD_BUG_HUNT_REPORT.md as a record of failure modes designed against here (silent data loss, turn-order corruption, no cascade deletes, NaN inputs, dead Tauri integration). The SRD data and Python scrapers were preserved.
