## Symptom
Grafana's \`app-crash-log\` alert fires on every deploy. The Loki query
that backs it (\`ERR_|FATAL|uncaughtException|…\`) matches:
Error [ERR_MODULE_NOT_FOUND]: Cannot find module
'/app/apps/journal/app/lib/logger.server' imported from
'/app/apps/journal/app/lib/email.server.ts'
A real bug, not a false positive: \`email.server.ts\` line 2 was
\`import { logger } from \"./logger.server\"\` — no extension.
## Why typecheck didn't catch it
\`tsconfig.base.json\` sets \`moduleResolution: \"bundler\"\`. The bundler
resolver accepts extensionless relative imports because Vite / esbuild
/ webpack resolve them at build time. TypeScript was happy.
Production runs \`node --experimental-strip-types server.ts\`, which
uses Node's NodeNext ESM resolver — strict about extensions. The two
resolvers disagree silently for files Node loads directly (server.ts,
\`.server.ts\` modules dynamically imported from it, and jobs).
## Fix
1. **Added \`.ts\` extensions to the 4 broken imports** I could find:
- \`apps/journal/app/lib/email.server.ts\` → \`./logger.server.ts\`
(the actual deploy-blocker)
- \`apps/planner/app/lib/brouter.ts\` → \`./route-merge.ts\`, \`./http.server.ts\`
- \`apps/planner/app/lib/use-nearby-pois.ts\` → \`./overpass.ts\`
- \`packages/map/src/MapView.tsx\` → \`./layers.ts\` (caught by the rule)
2. **Added \`eslint-plugin-import-x\` with \`import-x/extensions: always\`**,
scoped to files Node actually executes raw:
- \`apps/*/server.ts\`
- \`apps/*/app/lib/**/*.server.ts\`
- \`apps/*/app/jobs/**/*.ts\`
- \`packages/*/src/**/*.{ts,tsx}\`
Ignored: route-scoped \`*.server.ts\` files (bundled by Vite into the
React Router build, never loaded by Node), and test files (Vitest's
own resolver).
## What's still possible
- Non-\`.server.ts\` files in \`app/lib\` (e.g. \`legal.ts\`, \`actor-iri.ts\`)
could still ship extensionless imports. They're not in the lint
scope. If one breaks at runtime we can extend the glob — for now
they tend to be tiny utility modules that don't import other
relatives.
- The deeper fix would be \`moduleResolution: nodenext\` for server-side
tsconfig, or bundling the server code so Node never sees raw \`.ts\`.
Bigger surgery; the lint rule covers the failure mode for now.
Full repo: pnpm typecheck / lint / test all green after \`pnpm install\`.

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.
Project Structure
This is a TypeScript monorepo using pnpm workspaces and Turborepo.

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
