The vessel name list runs to tens of thousands of entries and every one was mounted as a button when the dialog opened, so the Maritime dialog took several seconds to appear. Because the dialog centres itself in an effect after the first paint, that delay also showed it flashing at the top-left before jumping to the middle. Mount at most 300 rows until the search narrows the list, say how many are hidden, and centre in a layout effect so the first paint is already in place.

ShadowBroker Frontend
Next.js 16 dashboard with MapLibre GL and Framer Motion.
Development
npm install
npm run dev # http://localhost:3000
API URL Configuration
The browser calls relative /api/* paths. The catch-all route handler at
src/app/api/[...path]/route.ts proxies those requests to the backend using
the server-side BACKEND_URL environment variable at request time.
This keeps the backend URL out of the client bundle and lets Docker or other deployments change the backend target without rebuilding the frontend.
Common Scenarios
| Scenario | Action needed |
|---|---|
Local dev (localhost:3000 + backend on 127.0.0.1:8000) |
None. The proxy defaults to http://127.0.0.1:8000. |
| Docker Compose | None. docker-compose.yml sets BACKEND_URL=http://backend:8000. |
| Backend on a different host or port | Set BACKEND_URL before starting the Next.js server/container. |
| Reverse proxy in front of the frontend | Point external clients at the frontend; keep BACKEND_URL set to the backend address reachable from the Next.js server. |
Setting BACKEND_URL
# Shell (Linux/macOS)
BACKEND_URL=http://myserver:8000 npm run dev
# PowerShell (Windows)
$env:BACKEND_URL="http://myserver:8000"; npm run dev
# Docker Compose
# Edit the frontend service environment or add a compose override:
# BACKEND_URL=http://myserver:8000
Theming
Dark mode is the default. A light/dark toggle is available in the left panel
toolbar. Theme preference is persisted in localStorage as sb-theme and
applied via the data-theme attribute on <html>. CSS variables in
globals.css define all structural colors for both themes.
