# Vectorography as one container: the app is built, then served by the same
# process that owns the space. Hugging Face Spaces runs this as-is.

# ---- build the app ----------------------------------------------------------

COPY frontend/package*.json ./
RUN npm ci
COPY frontend/ ./
# The version lives at the repository root, one level above the frontend the
# build stage is given.

# ---- serve it, and the space it reads from ----------------------------------
FROM python:3.12-slim

# The corpus font files are not shipped: three hundred megabytes of them, and

# Spaces fixes the port at 7860; Cloud Run hands one over in the environment
# and will not route to a container listening anywhere else.
