Replace Server-Sent Events streaming implementation with straightforward
JSON request/response pattern to simplify debugging and reduce complexity.
Changes:
- server.js: Convert /api/chat/stream to /api/chat with JSON response
- src/lib/api.ts: Remove SSE parsing logic, add ChatResponse interface
- src/hooks/useChat.ts: Handle JSON response instead of stream chunks
This change makes the request flow easier to debug and troubleshoot
while maintaining the same conversation functionality.
Remove the environment variable fallback for API_BASE_URL to ensure
all API requests are routed through the proxy server. This provides
consistent authentication and security handling in all environments.
Replace Python http.server with Express to handle:
- Large IAP JWT headers that caused 500 errors
- API request proxying with GCP identity tokens
- Static React build serving with SPA fallback
Update api.ts to use relative URLs in production for proxy routing.
