# Development override: run the UI edition straight from the source tree.
#
#   docker compose -f docker-compose.yml -f docker-compose.dev.yml --profile ui up -d
#   (or: npm run dev:docker)
#
# Node 24 strips the TypeScript types at load time, so the server needs no
# build step: `src` is mounted read-only and `node --watch` restarts it when a
# `.ts` file changes. The React dashboard still has a build step — Vite
# watches `src/ui/web` and rewrites `dist/ui/public` on every save, served at
# `/` by the express server. `WEB_DIR` has to be set explicitly here: its
# default (`./public/` next to app.ts, i.e. `src/ui/public`) no longer exists
# on disk at all, so without this the container would 404 on every asset.
#
# The `dev` build target (not `light`/`ui`) is required for this: it keeps the
# devDependencies (Vite) and the full source tree that the production image's
# `npm ci --omit=dev` deliberately drops. Rebuild the image (`--build`) after
# a dependency change; everything else is live.
#
# Three overrides stop this container from passing itself off as production:
# its own `image:` tag, so a dev build never overwrites the published
# `ghcr.io/devmanfre/isitdown:ui-latest`; no
# restart policy, so it cannot come back after a reboot as the thing listening
# on :3000; and no volume over `/app/dist`, so Vite's output lives and dies
# with the container instead of outliving the image it came from. The service
# keeps the base file's `container_name` and data volume on purpose — that is
# what makes dev and production mutually exclusive, so the two can never both
# hold the port or write the same SQLite file.
