Dockerfile

# Multi-stage build for Lolicount.
# Stage 1: build the Nuxt SSG frontend (Node 22 + pnpm 11).
# Stage 2: build the Go backend (themes + dist embedded-ready, pure Go, no CGO).
# Stage 3: minimal alpine runtime with the binary and data volume.

# ---- Stage 1: frontend ----
# BASE_URL is baked into the SSG bundle at build time (runtimeConfig.public.
# baseUrl → window.__NUXT__.config.public.baseUrl), so the embed links shown
# on the web UI point at the public domain. APP_VERSION carries the release
# tag shown in the footer (runtimeConfig.public.appVersion); CD passes the
# tag as a build arg so no source file needs editing on release. Pass via:
#   docker build --build-arg BASE_URL=https://lolicount.top \
#                --build-arg APP_VERSION=v0.4.4 -t lolicount .
# Empty = embed links fall back to same-origin; the version is omitted.
