Dockerfile

# Single-container production image: the Hono backend serves both the built
# frontend (frontend/dist) and the /api/* routes. Build context is the repo
# ROOT (it needs both frontend/ and backend/).
#
# Local dev is unaffected — developers still run the Vite dev-server and
# `npm run dev` separately. This image is a deploy concern only.

# 1) Build the frontend -> /frontend/dist (Vite). Includes the Google Docs
#    sidebar bundle (dist/google-docs.bundle.js), same as the old frontend image.
FROM node:24-slim AS frontend
WORKDIR /frontend
COPY frontend/package.json frontend/package-lock.json ./
RUN npm ci

RUN npm run build && npm run build:google-docs

# 2) Build the backend -> /app/backend/dist (tsc).
FROM node:24-slim AS backend
WORKDIR /app/backend
COPY backend/package.json backend/package-lock.json* ./
RUN npm install
COPY backend/tsconfig.json ./

# 3) Runtime: Node serving the compiled backend + the frontend as static files.
