Calling Cloud Functions
-
Overview
Overview of calling Cloud Functions.
-
HTTP Triggers
Use HTTP methods to trigger Cloud Functions.
-
Cloud Pub/Sub Triggers
Asynchronously trigger Cloud Functions via a Pub/Sub topic.
-
Cloud Storage Triggers
Trigger Cloud Functions in response to change notifications from Google Cloud Storage.
-
Direct Triggers
Manually invoke a Cloud Function for quick iteration and debugging.
-
Cloud Firestore Triggers
Trigger Cloud Functions in response to Firestore events.
-
Google Analytics for Firebase Triggers
Trigger Cloud Functions in response to Google Analytics for Firebase events.
-
Firebase Realtime Database Triggers
Trigger Cloud Functions in response to Firebase Realtime Database events.
-
Firebase Authentication Triggers
Trigger Cloud Functions in response to Firebase authentication events.
-
Second-Party Triggers with Stackdriver
Trigger Cloud Functions in response to events from Google Cloud Platform services that produce Stackdriver audit logs.
-
Using Cloud Scheduler to Trigger a Cloud Function
Invoke a Cloud Function on a time-based schedule using Cloud Scheduler and a Cloud Pub/Sub trigger. This enables you to set up cron jobs which run periodically at specific time intervals.
Testing Cloud Functions
-
Testing Basics
Learn how to create unit, system, and integration testing with Cloud Functions.
-
Testing HTTP Functions
Learn how to test HTTP Cloud Functions. Cloud Functions can be either HTTP functions, or background functions.
-
Testing Background Functions
Learn how to test background Cloud Functions. You use background functions when you want to have your Cloud Function invoked indirectly in response to an event, such as a message on a Cloud Pub/Sub topic, a change in a Cloud Storage bucket, or a Firebase event.
-
CI/CD
Learn how to configure a continuous integration and deployment (CI/CD) pipeline to run Cloud Functions tests on an ongoing basis.
