# Helper to automatically link any NPM modules that are in development.
#
# Mounting Custom Modules to the Docker Container:
#   Custom NPM modules must be mounted into the Docker container at
#
#   /usr/local/src/${module}
#
#   Here's an example Docker Compose mount for two modules, rimraf and eslint:
#
#       volumes:
#         - web-yarn:/home/node/.cache/yarn
#         - .:/usr/local/src/reaction-app
#         - ../rimraf:/usr/local/src/rimraf
#         - ../eslint:/usr/local/src/eslint
#
#
# Run this Script on Container Start:
#   Add this script to the Docker CMD to ensure that it links all modules
#   before starting the project process.
#
#   Example command:
#
#       command: [sh, -c, "bin/yarn-link && yarn run build && yarn run start"]


# NPM modules that will be linked.
# Set in .env
