PublisherClient

PublisherClient

Eventarc processes events generated by an event provider and delivers them to a subscriber.

An event provider is a software-as-a-service (SaaS) system or product that can generate and deliver events through Eventarc.

A third-party event provider is an event provider from outside of Google.

A partner is a third-party event provider that is integrated with Eventarc.

A subscriber is a GCP customer interested in receiving events.

Channel is a first-class Eventarc resource that is created and managed by the subscriber in their GCP project. A Channel represents a subscriber's intent to receive events from an event provider. A Channel is associated with exactly one event provider.

ChannelConnection is a first-class Eventarc resource that is created and managed by the partner in their GCP project. A ChannelConnection represents a connection between a partner and a subscriber's Channel. A ChannelConnection has a one-to-one mapping with a Channel.

Publisher allows an event provider to publish events to Eventarc.

keyFilename string <optional>

Full path to the a .json, .pem, or .p12 key downloaded from the Google Developers Console. If you provide a path to a JSON file, the projectId option below is not necessary. NOTE: .pem and .p12 require you to specify options.email as well.
port number <optional>

The port on which to connect to the remote host.
projectId string <optional>

The project ID from the Google Developer's Console, e.g. 'grape-spaceship-123'. We will also check the environment variable GCLOUD_PROJECT for your project ID. If your app is running in an environment which supports Application Default Credentials, your project ID will be detected automatically.
apiEndpoint string <optional>

The domain name of the API remote host.
clientConfig gax.ClientConfig <optional>

Client configuration override. Follows the structure of gapicConfig.
fallback boolean <optional>

Use HTTP/1.1 REST mode. For more information, please check the documentation.
gaxInstance gax <optional>

loaded instance of google-gax. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new PublisherClient({fallback: true}, gax);

getProjectId() → {Promise}

Return the project ID used by this class.

Returns:
Type Description
Promise

A promise that resolves to string containing the project ID.

initialize() → {Promise}

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns:
