# In order to run `npm run build` we need access to the Nest CLI.
# The Nest CLI is a dev dependency,
# In the previous development stage we ran `npm ci` which installed all dependencies.
# So we can copy over the node_modules directory from the development image into this build image.

# Running `npm ci` removes the existing node_modules directory.

I follow this tutorial https://www.tomray.dev/nestjs-docker-compose-postgres but I think it is related to some ts or nest versions because the same Dockerfile and docker-compose.yml but it is not working the hot reload. Because, the service is running and when I change files content I could verify the changes are reflected in docker image files but it is not triggering the rebuilding
