There is a firebase-functions-helper package, that can help to delete firebase users in bulk.

// Get all users 
firebaseHelper.firebase
    .getAllUsers(100)    
    .then(users => {        
        users.map(user => {
            firebaseHelper.firebase
                .deleteUsers([user.uid]);          
        })   
    })

The code above will get 100 users, and delete all of them. If you don't pass the number, the default value is 1000. You can read the instruction on Github repository.
