CloudSchedulerClient

CloudSchedulerClient

The Cloud Scheduler API allows external entities to reliably schedule asynchronous jobs.

Constructor

new CloudSchedulerClient(optionsopt, gaxInstanceopt)

Construct an instance of CloudSchedulerClient.

Parameters:
Name Type Attributes Description
options object <optional>

The configuration object. The options accepted by the constructor are described in detail in this document. The common options are:

Properties
Name Type Attributes Description
credentials object <optional>

Credentials object.

Properties
Name Type Attributes Description
client_email string <optional>
private_key string <optional>
email string <optional>

Account email address. Required when using a .pem or .p12 keyFilename.
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 | "rest" <optional>

Use HTTP fallback mode. Pass "rest" to use HTTP/1.1 REST API instead of gRPC. 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 CloudSchedulerClient({fallback: 'rest'}, gax);

Members

apiEndpoint

The DNS address for this API service - same as servicePath(), exists for compatibility reasons.

port

The port for this API service.

scopes

The scopes needed to make gRPC calls for every method defined in this service.

servicePath

The DNS address for this API service.

Methods

close() → {Promise}

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

Returns:
Type Description
Promise

A promise that resolves when the client is closed.

getLocation(request, optionsopt) → {Promise}

Gets information about a location.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
name string

Resource name for the location.
options object <optional>

Call options. See CallOptions for more details.
Returns:
Type Description
Promise
  • The promise which resolves to an array. The first element of the array is an object representing Location. Please see the documentation for more details and examples.
Example
```
const [response] = await client.getLocation(request);
```

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:
Type Description
Promise

A promise that resolves to an authenticated service stub.

jobPath(project, location, job) → {string}

Return a fully-qualified job resource name string.

Parameters:
Name Type Description
project string
location string
job string
Returns:
Type Description
string

Resource name string.

listJobsAsync(request, optionsopt) → {Object}

Equivalent to listJobs, but returns an iterable object.

for-await-of syntax is used with the iterable to get response elements on-demand.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Description
parent string

Required. The location name. For example: projects/PROJECT_ID/locations/LOCATION_ID.
filter string

filter can be used to specify a subset of jobs.

If filter equals target_config="HttpConfig", then the http target jobs are retrieved. If filter equals target_config="PubSubConfig", then the Pub/Sub target jobs are retrieved. If filter equals labels.foo=value1 labels.foo=value2 then only jobs which are labeled with foo=value1 AND foo=value2 will be returned.
pageSize number

Requested page size.

The maximum page size is 500. If unspecified, the page size will be the maximum. Fewer jobs than requested might be returned, even if more jobs exist; use next_page_token to determine if more jobs exist.
pageToken string

A token identifying a page of results the server will return. To request the first page results, page_token must be empty. To request the next page of results, page_token must be the value of next_page_token returned from the previous call to ListJobs. It is an error to switch the value of filter or order_by while iterating through pages.
legacyAppEngineCron boolean

This field is used to manage the legacy App Engine Cron jobs using the Cloud Scheduler API. If the field is set to true, the jobs in the __cron queue will be listed instead.
options object <optional>

Call options. See CallOptions for more details.
Returns:
Type Description
Object

An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing Job. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the documentation for more details and examples.

  callListJobs();

Returns:
Type Description
Stream

An object stream which emits an object representing Job on 'data' event. The client library will perform auto-pagination by default: it will call the API as many times as needed. Note that it can affect your quota. We recommend using listJobsAsync() method described below for async iteration which you can stop as needed. Please see the documentation for more details and examples.

listLocationsAsync(request, optionsopt) → {Object}

The resource that owns the locations collection, if applicable.
filter string

The standard list filter.
pageSize number

Returns:
Type Description
