"""Serve a SPA's dist/ directory + proxy API paths to a backend.
|
|
|
|
Usage: python3 proxy-server.py [--port PORT] [--dist DIST_DIR] [--backend BACKEND_URL]
|
|
|
|
Proxies:
|
|
/pb/* → BACKEND/api/* (PocketBase SDK path)
|
|
/api/* → BACKEND/api/* (direct API)
|
|
/deepseek/* → https://api.deepseek.com/* (with API key from /tmp/deepseek_key.txt)
|
|
/* → SPA static files (fallback to index.html for client-side routes)
|
|
|
|
Environment:
|
|
DEEPSEEK_KEY — API key for DeepSeek (overrides /tmp/deepseek_key.txt)
