# HF Docker Space image (issue #26). Built remotely by Hugging Face -- no local
# Docker needed. Two stages: build the React SPA with Node, then run FastAPI on
# a slim Python image that serves both the API and the built SPA on one port.

# --- stage 1: build the frontend ------------------------------------------
FROM node:20-slim AS frontend
WORKDIR /frontend
COPY frontend/package*.json ./
RUN npm ci
COPY frontend/ ./
# Same-origin: the SPA calls /api/... relative to wherever it's served.
ENV VITE_API_BASE=""
RUN npm run build

# --- stage 2: python serving runtime --------------------------------------
FROM python:3.11-slim
WORKDIR /app

COPY requirements-serve.txt .
RUN pip install --no-cache-dir -r requirements-serve.txt
