"""Serve SPA dist + proxy /pb to PocketBase + /deepseek to api.deepseek.com.
|
|
|
|
Reproducible from the spq-v2 deployment session. Drops into any PocketBase-backed
|
|
React SPA project that uses /pb as its PocketBase base URL. Serves the Vite build
|
|
output with SPA fallback, CORS headers, and PB/deepseek API proxying.
|
|
|
|
Usage:
|
|
python3 spa-pb-proxy.py
|
|
|
|
Env vars (optional — defaults are for the ShopProQuote spq-v2 deployment):
|
|
DIST_DIR - path to the Vite dist/ directory
|
|
PB_URL - PocketBase URL (default: http://127.0.0.1:8091)
|
|
PORT - listen port (default: 4173)
|
|
DS_KEY_FILE - path to file containing DeepSeek API key (default: /tmp/deepseek_key.txt)
