# ── StellarLock — development Dockerfile ─────────────────────────────────────
#
# Optimised for fast rebuilds:
#  • Installs dependencies in a separate layer so code changes don't trigger
#    a fresh `pnpm install`.
#  • Source tree is mounted as a volume at runtime, so Vite hot-reload works
#    without rebuilding the image.
#
# Usage (via docker-compose):
#   docker-compose up frontend
#
# Usage standalone:
#   docker build -f Dockerfile.dev -t stellarlock-dev .
#   docker run -p 5173:5173 -v $(pwd):/app stellarlock-dev

# ── Dependency layer ──────────────────────────────────────────────────────────
# Copy only the lockfile + manifests first so this layer is cached as long as
# dependencies don't change.

RUN pnpm install --frozen-lockfile

# ── Runtime ───────────────────────────────────────────────────────────────────
# Source code is intentionally NOT copied here — it is mounted as a volume at
# runtime so that Vite's hot-module replacement picks up edits immediately.
