Documentation

Overview

Package firestore is an auto-generated package for the Cloud Firestore API.

Accesses the NoSQL document database built for automatic scaling, high performance, and ease of application development.

General documentation

For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:

Example usage

To get started with this package, create a client. 

ctx := context.Background()
// 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.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := firestore.NewClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

Types

type CallOptions 

type CallOptions struct {

	GetOperation        []gax.CallOption
	ListOperations      []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type Client 

type Client struct {

	// The call options for this service.
	CallOptions *CallOptions
	// contains filtered or unexported fields
}

Client is a client for interacting with Cloud Firestore API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

The Cloud Firestore service.

Cloud Firestore is a fast, fully managed, serverless, cloud-native NoSQL document database that simplifies storing, syncing, and querying data for your mobile, web, and IoT apps at global scale. Its client libraries provide live synchronization and offline support, while its security features and integrations with Firebase and Google Cloud Platform accelerate building truly serverless apps.

func NewClient 

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewClient creates a new firestore client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

Output:

func (*Client) BatchGetDocuments 

func (c *Client) BatchGetDocuments(ctx context.Context, req *firestorepb.BatchGetDocumentsRequest, opts ...gax.CallOption) (firestorepb.Firestore_BatchGetDocumentsClient, error)

BatchGetDocuments gets multiple documents.

Documents returned by this method are not guaranteed to be returned in the same order that they were requested.

func (*Client) BatchWrite added in v1.3.0 

func (c *Client) BatchWrite(ctx context.Context, req *firestorepb.BatchWriteRequest, opts ...gax.CallOption) (*firestorepb.BatchWriteResponse, error)

BatchWrite applies a batch of write operations.

The BatchWrite method does not apply the write operations atomically and can apply them out of order. Method does not allow more than one write per document. Each write succeeds or fails independently. See the BatchWriteResponse for the success status of each write.

If you require an atomically applied set of writes, use Commit instead.

func (*Client) PartitionQuery added in v1.3.0 

func (c *Client) PartitionQuery(ctx context.Context, req *firestorepb.PartitionQueryRequest, opts ...gax.CallOption) *CursorIterator

PartitionQuery partitions a query by returning partition cursors that can be used to run the query in parallel. The returned partition cursors are split points that can be used by RunQuery as starting/end points for the query results.

func (c *Client) RunAggregationQuery(ctx context.Context, req *firestorepb.RunAggregationQueryRequest, opts ...gax.CallOption) (firestorepb.Firestore_RunAggregationQueryClient, error)

RunAggregationQuery runs an aggregation query.

Rather than producing Document results like Firestore.RunQuery, this API allows running an aggregation to produce a series of AggregationResult server-side.

High-Level Example:

func (c *Client) SetGoogleClientInfo(keyval ...string)

SetGoogleClientInfo sets the name and version of the application in the `x-goog-api-client` header passed on each request. Also passes any provided key-value pairs. Intended for use by Google-written clients.

Internal use only.

func (*Client) UpdateDocument 

func (c *Client) UpdateDocument(ctx context.Context, req *firestorepb.UpdateDocumentRequest, opts ...gax.CallOption) (*firestorepb.Document, error)

Example 
package main

import (
	"context"

	firestore "cloud.google.com/go/firestore/apiv1"
	firestorepb "cloud.google.com/go/firestore/apiv1/firestorepb"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.

	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := firestore.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &firestorepb.UpdateDocumentRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/cloud.google.com/go/firestore/apiv1/firestorepb#UpdateDocumentRequest.
	}
	resp, err := c.UpdateDocument(ctx, req)

	_ = resp
}

Output:

func (*Client) Write 

func (c *Client) Write(ctx context.Context, opts ...gax.CallOption) (firestorepb.Firestore_WriteClient, error)
