Cleanup user data upon account deletion.

This sample shows how to cleanup the user data when he deletes his account.

Functions Code

See file functions/index.js for the email sending code.

Sending emails is performed using nodemailer a node based Email client with comprehensive EMail server setup. In this sample we're showing how to send email through SMTP using a Gmail account. Be aware that Gmail has an email sending quota. If you are planning on sending a large number of emails you should use a professional email sending platform such as Sendgrid

The dependencies are listed in functions/package.json.

Sample Database Structure

When a user signs-in we write some sample personal data of the following form:

/functions-project-12345
    /users
        $uid : "Some user data"

When the user deletes his account a Function will trigger and automatically delete the corresponding user data in the realtime database.

Trigger rules

The function triggers on user account deletions.
