# --------------------------------------------------------------------------
# docker-compose.yml — One-command dev environment for the app.
#
# Key points:
# • `volumes` bind-mounts the project root into /app so file changes on
# the host are instantly visible inside the container (live reload).
# • An anonymous volume for node_modules prevents the host's
# node_modules from overriding the container's (they may differ by OS).
# • `ports` maps container 5173 → host 5173 so you can open the app
# at http://<host-ip>:5173 from any machine on your LAN.
# --------------------------------------------------------------------------
services:
dev:
build:
context: .
dockerfile: Dockerfile
ports:
- "5173:5173"
volumes:
# Mount the entire project directory into the container
- .:/app
# Keep container's node_modules separate from the host's.
# This anonymous volume is created once, then reused across restarts.
- /app/node_modules
environment:
# Tells Vite / chokidar to use polling for file-change detection,
# which is required when code lives on a bind-mounted volume.
- CHOKIDAR_USEPOLLING=true
# Keep stdin open so we can interact if needed (e.g. Ctrl-C)
