package firestore

import "cloud.google.com/go/firestore/apiv1beta1"

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. 

NOTE: This package is in beta. It is not stable, and may be subject to changes.

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.

For information about setting deadlines, reusing contexts, and more please visit godoc.org/cloud.google.com/go.

Deprecated: Please use "cloud.google.com/go/firestore/apiv1". This beta client will be removed in a future release.

func DefaultAuthScopes Uses

❖
func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

type CallOptions Uses

❖
type CallOptions struct {
    GetDocument       []gax.CallOption
    ListDocuments     []gax.CallOption
    CreateDocument    []gax.CallOption
    UpdateDocument    []gax.CallOption
    DeleteDocument    []gax.CallOption
    BatchGetDocuments []gax.CallOption
    BeginTransaction  []gax.CallOption
    Commit            []gax.CallOption

    RunQuery          []gax.CallOption
    Write             []gax.CallOption
    Listen            []gax.CallOption
    ListCollectionIds []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type Client Uses

❖
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.

func NewClient Uses

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

NewClient creates a new firestore client.

The Cloud Firestore service.

This service exposes several types of comparable timestamps: 

create_time - The time at which a document was created. Changes only
when a document is deleted, then re-created. Increases in a strict
monotonic fashion.

update_time - The time at which a document was last updated. Changes
every time a document is modified. Does not change when a write results
in no modifications. Increases in a strict monotonic fashion.

read_time - The time at which a particular state was observed. Used
to denote a consistent snapshot of the database or the time at which a
Document was observed to not exist.

commit_time - The time at which the writes in a transaction were
committed. Any read with an equal or greater read_time is guaranteed
to see the effects of the transaction.
Example

Code: 

ctx := context.Background()
c, err := firestore.NewClient(ctx)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use client.
_ = c
