Functions

Function Description
config() Store and retrieve project configuration data such as third-party API keys or other settings. You can set configuration values using the Firebase CLI as described in [Environment Configuration](/docs/functions/config-env).
optionsToEndpoint(options)
optionsToTrigger(options)
region(regions) Configure the regions that the function is deployed to.
runWith(runtimeOptions) Configure runtime options for the function.

Classes

Class Description
Change The Cloud Functions interface for events that change state, such as Realtime Database or Cloud Firestore onWrite and onUpdate events.For more information about the format used to construct Change objects, see below.
FunctionBuilder

Interfaces

Interface Description
BlockingFunction The function type for Auth Blocking triggers.
CloudFunction The function type for all non-HTTPS triggers. This should be exported from your JavaScript file to define a Cloud Function.This type is a special JavaScript function which takes a templated Event object as its only argument.
DeploymentOptions Configuration options for a function that applies during function deployment.
Event Wire format for an event.
EventContext The context in which an event occurred.
FailurePolicy Configuration option for failure policy on background functions.
HttpsFunction The function type for HTTPS triggers. This should be exported from your JavaScript file to define a Cloud Function.
Resource Resource is a standard format for defining a resource (google.rpc.context.AttributeContext.Resource). In Cloud Functions, it is the resource that triggered the function - such as a storage bucket.
Runnable A Runnable has a run method which directly invokes the user-defined function - useful for unit testing.
RuntimeOptions Configuration options for a function that applicable at runtime.
Schedule Configuration options for scheduled functions.
ScheduleRetryConfig Scheduler retry options. Applies only to scheduled functions.
