# Casual Sheets — development override.
#
#   docker compose -f docker-compose.yml -f docker-compose.dev.yml up
#
# Skips the prebuilt app image and runs the live Vite dev server + tsx
# watcher with the workspace bind-mounted, so hot reload works inside the
# container. Redis still comes from the same service in docker-compose.yml.
#
# For most local work, `pnpm dev:web` + `pnpm dev:server` on the host is
# faster — this file is for parity-testing the Docker network setup
# (Redis URL, WebSocket upgrade through the same container, etc.).

services:
  app:
    # Override the runtime image with a Node-only base; we run pnpm dev
    # against the bind-mount instead of executing a built artifact.
    image: node:22-alpine
    # Runs as root inside the container — fine for local dev. The
    # alternative (running as `node` uid 1000) was that `corepack
    # enable` couldn't symlink into root-owned /usr/local/bin, and the
    # anonymous node_modules volumes (which docker creates as root)
    # weren't writable by uid 1000 either. The bind-mounted source
    # tree is only WRITTEN by pnpm install when the lockfile drifts;
    # we use `--frozen-lockfile` so that errors out instead of writing
    # — meaning no root-owned files leak back to the host repo.
    working_dir: /app
    # pnpm via `npm i -g` instead of `corepack enable`: simpler, works
    # the same as root either way, and avoids the corepack symlink
    # permission dance entirely.
