# In this step we copy over everything we need and install all dependancies
# We stop at the end of this step in development, so it also includes the deploy command
# We install jest, eslint and ts-node so we can run tests and lint.

# Copy application dependency manifests to the container image.
# A wildcard is used to ensure copying both package.json AND package-lock.json (when available).
# Copying this first prevents re-running npm install on every code change.

# Use NPM CI even though this may be your first time, cuz package-lock already thinks you installed stuff
