# This script generates access tokens that are needed to make admin API
# calls to the Firebase Console.
#
# The script takes three arguments:
# - GHA_SECRET: The password for decrypting GitHub secrets.
# - SERVICE_ACCOUNT: The path to the encrypted service account secret.
# - OUTPUT: The path to file where generated access token will be stored.
#
# This script uses Google's Swift Auth Client Library.
# - https://github.com/googleapis/google-auth-library-swift
#
# Generated tokens are `JSON` in the form:
# {
# "token_type":"Bearer",
# "expires_in":3599,
# "access_token":"1234567890ABCDEFG"
# }
GHA_SECRET="$1" # Pass in `local_dev` if the SERVICE_ACCOUNT does not to be decrypted.

OUTPUT="$3"

# The access token is generated using a downloaded Service Account JSON file from a
# Firebase Project. This can be downloaded from Firebase console under 'Project Settings'.

# the GOOGLE_APPLICATION_CREDENTIALS env var to it.
