# This wrapper script is mainly for local development purpose only.
#
# Sourcing this script will perform:
#   1. get required config values from SSM Parameter Store
#   2. export them as REACT_x environment variables
#
# REQUIRED CLI:
# aws, jq
#
# USAGE:
#
# Otherwise source it standalone itself by:
#     source get_env.sh
#     source get_env.sh unset
#
# CAVEATS:
# If your Portal Django backend is not running on :8000, then before start
# you can override by, e.g.  export DATA_PORTAL_API_URL=localhost:5000
#
# Try to be POSIX-y. Only tested on macOS! Contrib welcome for other OSs.
