mauriceboe/TREK

A self-hosted, real-time collaborative travel planner — with maps, budgets, packing lists, a journal, and AI built in.

     
 

What you get

Get started in 30 seconds

ENCRYPTION_KEY=$(openssl rand -hex 32) docker run -d -p 3000:3000 \
  -e ENCRYPTION_KEY=$ENCRYPTION_KEY \
  -v ./data:/app/data -v ./uploads:/app/uploads mauriceboe/trek

Open http://localhost:3000. On first boot TREK seeds an admin account — if you set ADMIN_EMAIL/ADMIN_PASSWORD those are used, otherwise the credentials are printed to the container log (docker logs trek).

Tech stack

Real-time sync via WebSocket (ws). Backend on NestJS 11. State with Zustand. Auth via JWT + OAuth 2.1 + OIDC + Passkeys (WebAuthn) + TOTP MFA. Weather via Open-Meteo (no key required). Maps with Leaflet and Mapbox GL.

docker compose up -d

Helm (Kubernetes)

helm repo add trek https://chart.liketrek.com
helm repo update
helm install trek trek/trek

See charts/README.md for values.

Install as App (PWA)

TREK works as a Progressive Web App — no App Store needed.

1. Open TREK in the browser (HTTPS required)
2. iOS: Share ▸ Add to Home Screen
3. Android: Menu ▸ Install app (or Add to Home Screen)

TREK then launches fullscreen with its own icon, just like a native app.

Updating

Docker Compose:

docker compose pull && docker compose up -d

Docker run — reuse the original volume paths:

docker pull mauriceboe/trek
docker rm -f trek
docker run -d --name trek -p 3000:3000 -v ./data:/app/data -v ./uploads:/app/uploads --restart unless-stopped mauriceboe/trek

Not sure which paths you used? docker inspect trek --format '{{json .Mounts}}' before removing the container.

Your data stays in the mounted data and uploads volumes — updates never touch it.

[!IMPORTANT] Mount only the data and uploads directories — -v ./data:/app/data -v ./uploads:/app/uploads. Never mount a volume at /app. Doing so hides the application code shipped in the image and the container fails to start with Cannot find module 'tsconfig-paths/register'. If you previously mounted /app, switch to the two mounts above; your data in data/ and uploads/ is preserved.

Rotating the Encryption Key

If you need to rotate ENCRYPTION_KEY (e.g. upgrading from a version that derived encryption from JWT_SECRET):

docker exec -it trek node --import tsx scripts/migrate-encryption.ts

The script creates a timestamped DB backup before making changes and prompts for old + new keys (input is not echoed).

Reverse Proxy

For production, put TREK behind a TLS-terminating reverse proxy. TREK uses WebSockets for real-time sync, so the proxy must support WebSocket upgrades on /ws.

If you use the MCP addon, the proxy must also pass the Mcp-Session-Id header through in both directions on /mcp — Nginx and Caddy do this by default, but a proxy that strips it makes every tool call open a new session instead of reusing one. See the Reverse Proxy wiki page for details.
