Methods

createIndex

createIndex(request, options, callback) returns Promise

Creates a composite index. This returns a google.longrunning.Operation which may be used to track the status of the creation. The metadata for the operation will be the type IndexOperationMetadata.

Parameter
request	Object The request object that will be sent. Values in request have the following properties: Parameter parent string A parent name of the form projects/{project_id}/databases/{database_id}/collectionGroups/{collection_id} index Object The composite index to create. This object should have the same structure as Index
options	Optional Object Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.
callback	Optional function(nullable Error, nullable Object) The function which will be called with the result of the API call. The second parameter to the callback is an object representing Operation.

Returns

Promise 

• The promise which resolves to an array. The first element of the array is an object representing Operation. The promise has a method named "cancel" which cancels the ongoing API call.

Example

const firestore = require('@google-cloud/firestore');

const client = new firestore.v1.FirestoreAdminClient({
  // optional auth parameters.
});

const formattedParent = client.parentPath('[PROJECT]', '[DATABASE]',
'[COLLECTION_ID]'); const index = {}; const request = { parent:
formattedParent, index: index,
};
client.createIndex(request)
  .then(responses => {
    const response = responses[0];
    // doThingsWith(response)
  })
  .catch(err => {
    console.error(err);
  });

databasePath(project, database) returns String

Return a fully-qualified database resource name string.

Parameter
project	String
database	String

Returns

String 

deleteIndex

deleteIndex(request, options, callback) returns Promise

Deletes a composite index.

Parameter
request	Object The request object that will be sent. Values in request have the following properties: Parameter name string A name of the form projects/{project_id}/databases/{database_id}/collectionGroups/{collection_id}/indexes/{index_id}

formattedName}).catch(err => { console.error(err);
});

exportDocuments

exportDocuments(request, options, callback) returns Promise

Exports a copy of all or a subset of documents from Google Cloud Firestore to another storage system, such as Google Cloud Storage. Recent updates to documents may not be reflected in the export.

Return a fully-qualified index resource name string.

Parameter
project	String
database	String
collectionId	String
indexId	String

Returns

String 

listFields

listFields(request, options, callback) returns Promise

Lists the field configuration and metadata for this database.

Currently, FirestoreAdmin.ListFields only supports listing fields that have been explicitly overridden. To issue this query, call FirestoreAdmin.ListFields with the filter set to indexConfig.usesAncestorConfig:false.

Parameter
request	Object The request object that will be sent. Values in request have the following properties: Parameter parent string A parent name of the form projects/{project_id}/databases/{database_id}/collectionGroups/{collection_id} filter Optional string The filter to apply to list results. Currently, FirestoreAdmin.ListFields only supports listing fields that have been explicitly overridden. To issue this query, call FirestoreAdmin.ListFields with the filter set to indexConfig.usesAncestorConfig:false. pageSize Optional number The maximum number of resources contained in the underlying API response. If page streaming is performed per-resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page.
options	Optional Object Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.
callback	Optional function(nullable Error, nullable Array, nullable Object, nullable Object) The function which will be called with the result of the API call. The second parameter to the callback is Array of Field. When autoPaginate: false is specified through options, it contains the result in a single response. If the response indicates the next page exists, the third parameter is set to be used for the next request object. The fourth parameter keeps the raw response object of an object representing ListFieldsResponse.

Returns

Promise 

• The promise which resolves to an array. The first element of the array is Array of Field.

  When autoPaginate: false is specified through options, the array has three elements. The first element is Array of Field in a single response. The second element is the next request object if the response indicates the next page exists, or null. The third element is an object representing ListFieldsResponse.

  The promise has a method named "cancel" which cancels the ongoing API call.

Example

const firestore = require('@google-cloud/firestore');

const client = new firestore.v1.FirestoreAdminClient({
  // optional auth parameters.
});

// Iterate over all elements.
const formattedParent = client.parentPath('[PROJECT]', '[DATABASE]',
'[COLLECTION_ID]');

client.listFields({parent: formattedParent})
  .then(responses => {
    const resources = responses[0];
    for (const resource of resources) {
      // doThingsWith(resource)
    }
  })
  .catch(err => {
    console.error(err);
  });

// Or obtain the paged response.
const formattedParent = client.parentPath('[PROJECT]', '[DATABASE]',
'[COLLECTION_ID]');


const options = {autoPaginate: false};
const callback = responses => {
  // The actual resources in a response.
  const resources = responses[0];
  // The next request if the response shows that there are more responses.
  const nextRequest = responses[1];
  // The actual response object, if necessary.
  // const rawResponse = responses[2];
  for (const resource of resources) {
    // doThingsWith(resource);
  }
  if (nextRequest) {
    // Fetch the next page.
    return client.listFields(nextRequest, options).then(callback);
  }
}
client.listFields({parent: formattedParent}, options)
  .then(callback)
  .catch(err => {
    console.error(err);
  });

listFieldsStream

listFieldsStream(request, options) returns Stream

Equivalent to listFields, but returns a NodeJS Stream object.

This fetches the paged responses for listFields continuously and invokes the callback registered for 'data' event for each element in the responses.

The returned object has 'end' method when no more elements are required.

autoPaginate option will be ignored.

Parameter
request	Object The request object that will be sent. Values in request have the following properties: Parameter parent string A parent name of the form projects/{project_id}/databases/{database_id}/collectionGroups/{collection_id} filter Optional string The filter to apply to list results.

This call returns a google.longrunning.Operation which may be used to track the status of the field update. The metadata for the operation will be the type FieldOperationMetadata.

To configure the default field settings for the database, use the special Field with resource name: projects/{project_id}/databases/{database_id}/collectionGroups/default/fields/*.

Parameter
request	Object The request object that will be sent. Values in request have the following properties: Parameter field Object The field to be updated. This object should have the same structure as Field updateMask Optional Object A mask, relative to the field. If specified, only configuration specified by this field_mask will be updated in the field. This object should have the same structure as FieldMask

callback	Optional function(nullable Error, nullable Object) The function which will be called with the result of the API call. The second parameter to the callback is an object representing Operation.

Returns

Promise 

• The promise which resolves to an array. The first element of the array is an object representing Operation. The promise has a method named "cancel" which cancels the ongoing API call.

Example

const firestore = require('@google-cloud/firestore');

const client = new firestore.v1.FirestoreAdminClient({
  // optional auth parameters.
});

const field = {};
client.updateField({field: field})
  .then(responses => {
    const response = responses[0];
    // doThingsWith(response)
  })
  .catch(err => {
    console.error(err);
  });
