How do you setup local environment variables for Cloud Functions for Firebase

Question

I\'m using http cloud functions to listen for a request and then return a simple message.

I\'m developing cloud functions locally using:

firebase se

For those who want to use the environment variables (process.env), I follow this workaround.

Set the config values before deploying

firebase functions:config:set envs.db_host=$DB_HOST_PROD envs.db_user=$DB_USER_PROD envs.db_password=$DB_PASSWORD_PROD envs.db_name=$DB_NAME_PROD envs.db_use_ssl=false

Read the config and update the env variables first thing under your functions code.

const functions = require('firebase-functions');
const config = functions.config();
// Porting envs from firebase config
for (const key in config.envs){
  process.env[key.toUpperCase()] = config.envs[key];
}
