Environment Variables


firebase functions:config:set config.key="SECRET_KEY" config.pass="SECRET_PASS"

NOTE: You must redeploy functions to make the new configuration available

Accessing env variables​

const secretKey  = firebase.config().config.key;
const secretPass = firebase.config().config.pass;

Retrieve all variables​

firebase functions:config:get

Unset a variable​

firebase functions:config:unset config.key

Using a file where we can keep all the environment variables.​

env.json, a file that will contain all our environment variables.

{
  "config": {
    "host": "domain",
    "key": "SECRET_KEY",
    "pass": "SECRET_PASS"
  }
}

How to deploy the variables with the env.json file?

firebase functions:config:set env="$(cat env.json)"
