# this can only be run successfully with docker-compose file

# Specify node version and choose image
# also name our image as development (can be anything)

# Set node env to prod
ARG NODE_ENV=production

# Specify our working directory, this is in our container/in our image

# Copy the package.jsons from host to container
# A wildcard is used to ensure both package.json AND package-lock.json are copied

# Here we install all the deps
RUN npm install --only=dev
RUN npm install rimraf
