Manages services of an application. v1

Package

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of ServicesClient.

Parameters
Name	Description
`opts`	`ClientOptions`
`gaxInstance`	`typeof gax \| typeof fallback` : 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 ServicesClient({fallback: true}, gax); ```

    ]>;

Lists all the services in the application.

Parameters
Name	Description
`request`	`IListServicesRequest` The request object that will be sent.

Returns

Type Description

Promise<[

        protos.google.appengine.v1.IListServicesRequest | null,
        protos.google.appengine.v1.IListServicesResponse
    ]>

{Promise} - The promise which resolves to an array. The first element of the array is Array of Service. The client library will perform auto-pagination by default: it will call the API as many times as needed and will merge results from all the pages into this array. Note that it can affect your quota. We recommend using listServicesAsync() method described below for async iteration which you can stop as needed. Please see the documentation for more details and examples.

listServices(request, options, callback)

listServices(request: protos.google.appengine.v1.IListServicesRequest, options: CallOptions, callback: PaginationCallback<protos.google.appengine.v1.IListServicesRequest, protos.google.appengine.v1.IListServicesResponse | null | undefined, protos.google.appengine.v1.IService>): void;

Parameters
Name	Description
`request`	`IListServicesRequest`
`options`	`CallOptions`
`callback`	`PaginationCallback<protos.google.appengine.v1.IListServicesRequest, protos.google.appengine.v1.IListServicesResponse \| null \| undefined, protos.google.appengine.v1.IService>`

Returns
Type	Description
`void`

listServices(request, callback)

listServices(request: protos.google.appengine.v1.IListServicesRequest, callback: PaginationCallback<protos.google.appengine.v1.IListServicesRequest, protos.google.appengine.v1.IListServicesResponse | null | undefined, protos.google.appengine.v1.IService>): void;

Parameters
Name	Description
`request`	`IListServicesRequest`
`callback`	`PaginationCallback<protos.google.appengine.v1.IListServicesRequest, protos.google.appengine.v1.IListServicesResponse \| null \| undefined, protos.google.appengine.v1.IService>`

Returns
Type	Description
`void`

listServicesAsync(request, options)

listServicesAsync(request?: protos.google.appengine.v1.IListServicesRequest, options?: CallOptions): AsyncIterable<protos.google.appengine.v1.IService>;

Equivalent to listServices, but returns an iterable object.

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

Parameters
Name	Description
`request`	`IListServicesRequest` The request object that will be sent.
`options`	`CallOptions` Call options. See CallOptions for more details.

Returns
Type	Description
`AsyncIterable<protos.google.appengine.v1.IService>`	{Object} An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing Service. 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.

Example


  /**
   * This snippet has been automatically generated and should be regarded as a code template only.
   * It will require modifications to work.
   * It may require correct/in-range values for request initialization.
   * TODO(developer): Uncomment these variables before running the sample.

  /**
   *  Name of the parent Application resource. Example: `apps/myapp`.
   */
  // const parent = 'abc123'
  /**
   *  Maximum results to return per page.
   */
  // const pageSize = 1234
  /**
   *  Continuation token for fetching the next page of results.
   */
  // const pageToken = 'abc123'

  // Imports the Appengine library
  const {ServicesClient} = require('@google-cloud/appengine-admin').v1;

  // Instantiates a client
  const appengineClient = new ServicesClient();

  async function callListServices() {
    // Construct request
    const request = {
    };

    // Run request
    const iterable = appengineClient.listServicesAsync(request);
    for await (const response of iterable) {
        console.log(response);
    }
  }

  callListServices();

listServicesStream(request, options)

listServicesStream(request?: protos.google.appengine.v1.IListServicesRequest, options?: CallOptions): Transform;

`options`	`CallOptions` Call options. See CallOptions for more details.

Returns

Type Description
