Two bugs introduced by the Next.js proxy Route Handler:
1. ERR_CONTENT_DECODING_FAILED — Node.js fetch() automatically
decompresses gzip/br responses from the backend, but the proxy was
still forwarding Content-Encoding and Content-Length headers to the
browser. The browser would then try to decompress already-decompressed
data and fail. Fixed by stripping Content-Encoding and Content-Length
from upstream response headers.
2. BACKEND_URL shell env leak into Docker Compose — docker-compose.yml
used ${BACKEND_URL:-http://backend:8000}, which was being overridden
by BACKEND_URL=http://localhost:8000 set in .mise.local.toml for local
dev. Inside the frontend container, localhost:8000 does not exist,
causing all proxied requests to return 502. Fixed by hardcoding
http://backend:8000 in docker-compose.yml so the shell environment
cannot override it.

ShadowBroker Frontend
Next.js 16 dashboard with MapLibre GL, Cesium, and Framer Motion.
Development
npm install
npm run dev # http://localhost:3000
API URL Configuration
The frontend needs to reach the backend (default port 8000). Resolution order:
NEXT_PUBLIC_API_URLenv var — if set, used as-is (build-time, baked by Next.js)- Server-side (SSR) — falls back to
http://localhost:8000 - Client-side (browser) — auto-detects using
window.location.hostname:8000
Common scenarios
| Scenario | Action needed |
|---|---|
Local dev (localhost:3000 + localhost:8000) |
None — auto-detected |
LAN access (192.168.x.x:3000) |
None — auto-detected from browser hostname |
| Public deploy (same host, port 8000) | None — auto-detected |
Backend on different port (e.g. 9096) |
Set NEXT_PUBLIC_API_URL=http://host:9096 before build |
| Backend on different host | Set NEXT_PUBLIC_API_URL=http://backend-host:8000 before build |
Behind reverse proxy (e.g. /api path) |
Set NEXT_PUBLIC_API_URL=https://yourdomain.com before build |
Setting the variable
# Shell (Linux/macOS)
NEXT_PUBLIC_API_URL=http://myserver:8000 npm run build
# PowerShell (Windows)
$env:NEXT_PUBLIC_API_URL="http://myserver:8000"; npm run build
# Docker Compose (set in .env file next to docker-compose.yml)
NEXT_PUBLIC_API_URL=http://myserver:8000
Note: This is a build-time variable. Changing it requires rebuilding the frontend.
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
data-theme attribute on <html>. CSS variables in globals.css define all
structural colors for both themes.
