initialize()

initialize(): Promise<{
        [name: string]: Function;
    }>;

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<{ [name: string]: Function; }>	{Promise} A promise that resolves to an authenticated service stub.

listCatalogs(request, options)

listCatalogs(request?: protos.google.cloud.retail.v2.IListCatalogsRequest, options?: CallOptions): Promise<[

        protos.google.cloud.retail.v2.IListCatalogsRequest | null,
        protos.google.cloud.retail.v2.IListCatalogsResponse
    ]>;

Lists all the s associated with the project.

Parameters

Name	Description
request	`protos.google.cloud.retail.v2.IListCatalogsRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type Description

Promise<[ protos.google.cloud.retail.v2.ICatalog[], protos.google.cloud.retail.v2.IListCatalogsRequest | null, protos.google.cloud.retail.v2.IListCatalogsResponse ]>

{Promise} - The promise which resolves to an array. The first element of the array is Array of [Catalog]. 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 listCatalogsAsync() method described below for async iteration which you can stop as needed. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

listCatalogsAsync(request, options)

listCatalogsAsync(request?: protos.google.cloud.retail.v2.IListCatalogsRequest, options?: CallOptions): AsyncIterable<protos.google.cloud.retail.v2.ICatalog>;

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

Parameters

Name	Description
request	`protos.google.cloud.retail.v2.IListCatalogsRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type

Description

AsyncIterable<protos.google.cloud.retail.v2.ICatalog>

{Object} An iterable Object that allows [async iteration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols). When you iterate the returned iterable, each element will be an object representing [Catalog]. 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](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

   *  If the caller does not have permission to list

  // const pageToken = 'abc123'

  // Imports the Retail library
  const {CatalogServiceClient} = require('@google-cloud/retail').v2;

  // Instantiates a client
  const retailClient = new CatalogServiceClient();

  async function callListCatalogs() {
    // Construct request
    const request = {
      parent,
    };

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

  callListCatalogs();

listCatalogsStream(request, options)

setDefaultBranch(request, options)

setDefaultBranch(request?: protos.google.cloud.retail.v2.ISetDefaultBranchRequest, options?: CallOptions): Promise<[
        protos.google.protobuf.IEmpty,
        protos.google.cloud.retail.v2.ISetDefaultBranchRequest | undefined,
        {} | undefined
    ]>;

Set a specified branch id as default branch. API methods such as , , will treat requests using "default_branch" to the actual branch id set as default.

For example, if projects/* /locations/* /catalogs/* /branches/1 is set as default, setting to projects/* /locations/* /catalogs/* /branches/default_branch is equivalent to setting to projects/* /locations/* /catalogs/* /branches/1.

Using multiple branches can be useful when developers would like to have a staging branch to test and verify for future usage. When it becomes ready, developers switch on the staging branch using this API while keeping using projects/* /locations/* /catalogs/* /branches/default_branch as to route the traffic to this staging branch.

CAUTION: If you have live predict/search traffic, switching the default branch could potentially cause outages if the ID space of the new branch is very different from the old one.

More specifically:

* PredictionService will only return product IDs from branch {newBranch}. * SearchService will only return product IDs from branch {newBranch} (if branch is not explicitly set). * UserEventService will only join events with products from branch {newBranch}.

Parameters

Name	Description
request	`protos.google.cloud.retail.v2.ISetDefaultBranchRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type	Description
Promise<[ protos.google.protobuf.IEmpty, protos.google.cloud.retail.v2.ISetDefaultBranchRequest \| undefined, {} \| undefined ]>	{Promise} - The promise which resolves to an array. The first element of the array is an object representing [Empty]. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#regular-methods) for more details and examples.
