Cloud Functions are rather powerful when it comes to triggering actions based on events that occur within Firebase. In today's lesson, we'll learn how to setup Firebase Tools CLI for the terminal, and initialize a Cloud Functions project. This requires that you have Node installed on your system and that npm is available on the command line.
Once we are done setting up our project, we deploy the helloWorld function to Firebase and see how we can interact with it. Finally, we send a push notification through FCM using our FCM Token from last episode.
