Send a survey when users update your app
This sample shows how to send a survey to your users who have updated your app. App Update is detected using a Firebase Analytics event.
Functions Code
See file functions/index.js for the trigger and the email sending code.
Sending emails is performed using nodemailer a node based Email client with comprehensive EMail server setup. For simplicity, 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, Mailjet or Mailgun.
The dependencies are listed in functions/package.json.
Trigger rules
The function triggers on changes to app_update
Firebase Analytics events. For other automatically logged events see: https://support.google.com/firebase/answer/6317485
Setting up the sample
Set the gmail.email
and gmail.password
Google Cloud environment variables to match the email and password of the Gmail account used to send emails. For this use:
firebase functions:config:set gmail.email="myusername@gmail.com" gmail.password="secretpassword"
Deploy and test
This sample can be tested on your Android and iOS app. To test it out:
- Make sure you set the
