This sample demonstrates how to delete the accounts of users who have not signed-in in the last month.

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

Note: This function uses Cloud Scheduler and Pub/Sub, which can have associated costs. Your project must be on the Blaze payment plan as these features require billing information. See the Cloud Scheduler pricing page for more information.

The dependencies are listed in functions/package.json.

To set up the sample:

• Create a Firebase Project using the Firebase Developer Console
• Download this sample e.g. git clone https://github.com/firebase/functions-samples

• Setup the sample with your project firebase use --add and follow the instructions.
• Install node dependencies of your Functions cd functions; npm install; cd -
