Moving one waypoint previously re-fetched all N-1 segments of the route
through /api/route every time, because the server-side computeRoute
recomputes the whole route from scratch. Under rapid edits this piles up
on BRouter's thread pool and wastes BRouter+Planner cycles on segments
the caller already has.
This change keeps a host-local LRU segment cache in the Planner tab,
keyed by (from, to, profile, noGoHash). On each computeRoute:
- build the pair list from the current waypoints
- split into cached vs. missing by looking up each pair key
- if any missing, POST { pairs: missing, … } to the new
/api/route-segments endpoint and populate the cache with its ordered
raw BRouter responses
- merge cache-ordered segments into an EnrichedRoute client-side via
mergeGeoJsonSegments (moved to a pure, isomorphic route-merge.ts)
- write to yjs.routeData exactly as before
Typical drag of one waypoint in a 10-waypoint route drops from 9 BRouter
fetches to 2. A session re-entering a cached arrangement (undo/redo)
short-circuits the server entirely. Profile/no-go changes invalidate all
keys and trigger a full refetch, matching prior behavior.
Yjs stays out of the cache: segments are bulky and CRDT sync of large
blobs hurts more than it helps. The elected host owns the cache; on host
handover the new host pays one full recompute.
Backwards-compat: /api/route is unchanged for external callers (e2e
integration tests, the Journal demo-bot's format=gpx path). Server-side
it now delegates to the shared fetchSegments helper.

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
