gcloud secrets list --project <PROJECT_ID>

deployment

the .env file is not versioned. At deployment, firebase sends the .env file to firebase servers.

v1 (deprecated)

Tell firebase to save a token/key on our behalf so that we can access it by reference in code, without writing the actual key in code and in git as a result.

firebase functions:config:set sendgrid.key="...." sendgrid.template="TEMP"

Read from Env

Firebase exposes the tokens/keys in an object we get through the config() method.

const API_KEY = functions.config().myKey
