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 (batch-add from bestiary, custom creatures with optional stats), 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
- Player characters — create reusable player character templates with name, AC, HP, color, and icon; search and add them to encounters with pre-filled stats; manage (edit/delete) from a dedicated panel
- Persistent — encounters survive page reloads via localStorage; bestiary data cached in IndexedDB; player characters stored independently
Prerequisites
- Node.js 22+

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.
