Three reports from the same week, all "the layout is in my way". #2247 — the Plan tab shows both side panels from 768px up, unconditionally. A Pixel 10 Pro Fold unfolded is ~860 CSS px, so 340 + 300 of panel left the map a 200px strip; those same widths became fit padding, shrinking the framing window to 140px and opening the camera two zoom levels out over half of East Asia. The floating POI/compass cluster is centred on the viewport at z-25, which at that width put it on top of both collapse tabs (z-1 inside z-20 containers) and on the Add Place/Activity button — and its pills set pointer-events: auto, so it ate the taps meant for them. The resize handles are mousedown-only, so a touch user could not narrow anything either. Between 768 and 1023px only one panel is open now, the day plan first, the places list one tap away — the Google Maps shape the reporter asked for. The collapse flags stay the wide-layout state, so a fold back restores what was there, and a marker tap reopening "both" no longer re-crowds the screen. The control cluster centres on the corridor the panels leave (the formula PlaceInspector and DayDetailPanel already use), the tabs finally have accessible names, the dead resize handles go, and a panel dragged to 520px on a desktop is clamped so the map keeps 360px without touching the stored width. computeMapViewport refuses to frame for less than a third of the box, so absurd padding can never pick the zoom again. #2248 — the public journey hero clips its own overflow to keep its decorative circles from widening the document, which also amputated the language menu at the hero's bottom edge: 8 of 23 locales, the rest unreachable. Both share pages inlined the same menu, so it is one component now, portalled to the body and anchored to its trigger the way CustomSelect is, with a height cap and its own scroll. It closes on Escape and on an outside click, which it never did, and `zh-TW` stops labelling itself 简体中文. #2249 — the note row's pencil/trash pill is absolutely positioned over the row's own reorder chevrons, and a coarse-pointer `opacity: 1 !important` pinned it permanently visible on tablets. On a mouse it was no better: the chevrons are revealed on hover, which is exactly when the opaque pill covers them, so note reordering has never been clickable on any pointer. The pill is gone; the row opens the note the way the phone shell already does, and delete lives in that dialog behind the same confirmation. A link in the note body keeps its own tap, on both shells. Closes #2247 Closes #2248 Closes #2249

AI usage
We use LLM-assisted coding tools across parts of this codebase. Nothing ships that a maintainer has not read and understood: every change goes through a pull request, is reviewed and tested, and has a human who can answer for it. "The AI wrote that" is not an answer any of us would accept from ourselves.
See How we use AI in TREK for the details.
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 (production)
The repository ships a ready-to-use docker-compose.yml
with secure defaults and every option documented inline. Download it, then:
docker compose up -d
See Install with Docker Compose for the full walkthrough.
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.
- Open TREK in the browser (HTTPS required)
- iOS: Share ▸ Add to Home Screen
- Android: Menu ▸ Install app (or Add to Home Screen)
TREK then launches fullscreen with its own icon, just like a native app.
Updating
See Updating — Docker Compose, Docker run, Helm, Portainer, Unraid and Proxmox, plus the encryption-key note.
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.
