Overview

Cloud Firestore

Cloud Firestore is a NoSQL document database built for automatic scaling, high performance, and ease of application development. While the Cloud Firestore interface has many of the same features as traditional databases, as a NoSQL database it differs from them in the way it describes relationships between data objects.

See Firestore Overview.

.configure {|Google::Cloud.configure.firestore| ... } ⇒ Google::Cloud::Config

Configure the Google Cloud Firestore library.

The following Firestore configuration parameters are supported:

  • project_id - (String) Identifier for a Firestore project. (The parameter project is considered deprecated, but may also be used.)
  • credentials - (String, Hash, Google::Auth::Credentials) The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Credentials) (The parameter keyfile is considered deprecated, but may also be used.)
  • scope - (String, Array) The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access.
  • timeout - (Integer) Default timeout to use in requests.
  • client_config - (Hash) A hash of values to override the default behavior of the API client.

Yields:

Returns:

  • (Google::Cloud::Config) —

.new(project_id: nil, credentials: nil, scope: nil, timeout: nil, client_config: nil, project: nil, keyfile: nil) ⇒ Google::Cloud::Firestore::Client

Creates a new object for connecting to the Firestore service. Each call creates a new connection.

For more information on connecting to Google Cloud see the Authentication Guide.

Examples:

require "google/cloud/firestore"

firestore = Google::Cloud::Firestore.new

Parameters:

  • project_id (String) —

    Identifier for a Firestore project. If not present, the default project for the credentials is used.

  • credentials (String, Hash, Google::Auth::Credentials) —

    The path to the keyfile as a String, the contents of the keyfile as a Hash, or a Google::Auth::Credentials object. (See Credentials)

  • scope (String, Array<String>) —

    The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs.

    The default scope is:

    • https://www.googleapis.com/auth/datastore
  • timeout (Integer) —

    Default timeout to use in requests. Optional.

  • client_config (Hash) —

    A hash of values to override the default behavior of the API client. Optional.

  • project (String) —

    Alias for the project_id argument. Deprecated.

  • keyfile (String) —

    Alias for the credentials argument. Deprecated.

Returns:

Raises:

  • (ArgumentError)
