docker-compose.dev.yaml

# Development overlay: edit backend code and see it running in seconds, with no image rebuild.
#
# Append it to whichever mode you are in:
#
#   COMPOSE_FILE=docker-compose.yaml:examples/postgres/compose.yaml:docker-compose.dev.yaml
#   COMPOSE_FILE=docker-compose.yaml:docker-compose.dev.yaml                  # Adopter Mode
#
# It overrides the backend only. An adopter running Adopter Mode has no demo client for an
# overlay to reference, so the client's own dev loop is `cd frontend && pnpm dev` on the host.

services:
  backend:
    # tsx watch, already in the backend's scripts — restarts on save.
    command: ["pnpm", "dev"]
    volumes:
      # Your working tree, live in the container.
      - ./backend:/app
      # Keeps the image's Linux node_modules. Without this the bind mount above shadows them with
      # the host's, which on macOS means native binaries the container cannot run.
