Addresses planner audit #5 — a connected client could feed unlimited waypoints / no-go / notes into the Yjs doc, growing the in-memory map and the persisted \`sessions.yjs_state\` blob until OOM or DB blowout. Two guards: 1. **Per-frame**: \`MAX_MESSAGE_BYTES = 256 KB\`. Anything bigger arrives from a buggy or hostile client — a single waypoint add is hundreds of bytes. Oversized frame → \`ws.close(1008)\` and drop the message. 2. **Per-doc**: \`MAX_DOC_BYTES = 5 MB\`. After a sync-message apply succeeds, recompute \`Y.encodeStateAsUpdate(doc).byteLength\`. If it crossed the cap, mark the session \"quarantined\": close every connected client (\`1008 policy violation\`), and short-circuit subsequent handleMessage calls so no further bytes can be applied and the debounced save can't write an oversized blob to Postgres. The 5 MB limit is generous — a typical multi-day route's serialized state is well under 100 KB. The cap exists to make abuse expensive, not to constrain real use. Exports \`MAX_MESSAGE_BYTES\`, \`MAX_DOC_BYTES\`, and \`docByteSize\` for testing. Tests cover: - constants are positive and ordered - docByteSize is 0 for unknown sessions - a realistic 500-waypoint route stays well under the cap - ~6MB of garbage in a Y.Text trips the cap (smoke test for the guard) Full repo: pnpm typecheck / lint / test all green.

trails.cool
Collaborative route planning and federated activity sharing for outdoor enthusiasts.
Planner — Plan routes together in real-time. Share a link, invite friends, edit waypoints collaboratively. Powered by BRouter for intelligent routing with elevation awareness.
Journal — Track your adventures. Import activities from Garmin, Strava, or Wahoo. Share routes and rides with friends. Self-host your own instance and federate with others via ActivityPub.
Status
Early development. See the architecture plan and project philosophy.

Getting Started
Prerequisites: Node.js 20+, pnpm, Docker
# Clone
git clone https://github.com/trails-cool/trails.git
cd trails
# Install dependencies
pnpm install
# Start development (apps only, no database or routing)
pnpm dev
# Start full stack (PostgreSQL + BRouter + apps)
pnpm dev:full
Full Local Dev Setup
pnpm dev:full starts everything needed to test the Planner end-to-end:
- PostgreSQL + PostGIS on port 5432 (via Docker)
- BRouter routing engine on port 17777 (via Docker)
- Database schema pushed automatically via Drizzle
- BRouter segment downloaded for Berlin area (~124MB, cached)
- Journal on http://localhost:3000
- Planner on http://localhost:3001
Other useful commands:
pnpm dev:services # Start Docker services only (DB + BRouter)
pnpm db:push # Push database schema changes
pnpm db:studio # Open Drizzle Studio (DB browser)
Development Tools
This project uses AI-assisted, spec-driven development. See docs/tooling.md for details.
| Tool | Purpose |
|---|---|
| cmux | Native macOS terminal for running multiple AI coding sessions |
| Claude Code | AI coding assistant (primary development tool) |
| GitHub Copilot | AI coding assistant |
| Crit | Browser-based inline code review |
| OpenSpec | Spec-driven development workflow |
Self-Hosting
The Journal is designed to be self-hosted. A single Docker Compose file gets you running:
curl -O https://raw.githubusercontent.com/trails-cool/trails/main/infrastructure/docker-compose.yml
docker compose up -d
See docs/architecture.md for details on self-hosting configuration.
Philosophy
- Privacy by design — The Planner collects zero user data
- Data ownership — Export everything, self-host, no lock-in
- Open source — MIT licensed, built on open standards
- Simplicity — Start simple, add complexity only when needed
