Cloud Functions for Firebase with Node Mail
Serverless Mailsender
Setup
You can clone this project with git clone git@github.com:Nismit/cffnm.git after that you need to setup Firebase Project and the project plan shoud be Blaze Plan because Firebase Function will be able to use with Blaze Plan only. When you created a Firebase project, you'll set the project id to .firebaserc
{
"projects": {
"default": "<Project Name>"
}
}
Set Environment Variable
The email sender is using Gmail System. It needs email address and password. For security reason, you need to set the environement variables into Firebase via Firebase CLI. https://firebase.google.com/docs/functions/config-env
firebase functions:config:set someservice.email="example@gmail.com" someservice.password="Gmail password"
The varibales are using auth object, so you have to change the variable path (https://github.com/Nismit/cffnm/blob/master/functions/index.js#L11-L14)
