Encounter Console

A local-first initiative tracker and encounter manager for tabletop RPGs (D&D 5e / 2024). Runs entirely in the browser — no server, no account, no data leaves your machine.

What it does

• Initiative tracking — add combatants, roll initiative (manual or d20), cycle turns and rounds
• Encounter state — HP, AC, conditions, concentration tracking with visual status indicators
• Bestiary integration — import bestiary JSON sources, search creatures, and view full stat blocks
• Persistent — encounters survive page reloads via localStorage; bestiary data cached in IndexedDB

Prerequisites

• Node.js 22+
• pnpm 10.6+

Project Structure

apps/web/          React 19 + Vite — UI components, hooks, adapters
packages/domain/   Pure functions — state transitions, types, validation
packages/app/      Use cases — orchestrates domain via port interfaces
data/bestiary/     Bestiary index for creature search
scripts/           Build tooling (layer boundary checks, index generation)
specs/             Feature specifications (spec → plan → tasks)

Architecture

Strict layered architecture with enforced dependency direction:

apps/web (adapters)  →  packages/application (use cases)  →  packages/domain (pure logic)

Domain is pure — no I/O, no randomness, no framework imports. Layer boundaries are enforced by automated import checks that run as part of the test suite. See CLAUDE.md for full conventions.
