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.

Class Method Details

.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.
  • quota_project - (String) The project ID for a project that can be used by client libraries for quota and billing purposes.
  • timeout - (Integer) Default timeout to use in requests.
  • endpoint - (String) Override of the endpoint host name, or nil to use the default endpoint.
  • emulator_host - (String) Host name of the emulator. Defaults to ENV["FIRESTORE_EMULATOR_HOST"]

Yields:

Returns:

  • (Google::Cloud::Config) —

    The configuration object the Google::Cloud::Firestore library uses.

.new(project_id: nil, credentials: nil, scope: nil, timeout: nil, endpoint: nil, emulator_host: nil, database_id: nil, transport: 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) (defaults to: nil) —

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

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

    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>) (defaults to: nil) —

    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) (defaults to: nil) —

    Default timeout to use in requests. Optional.

  • endpoint (String) (defaults to: nil) —

    Override of the endpoint host name. Optional. If the param is nil, uses the default endpoint.

  • emulator_host (String) (defaults to: nil) —

    Firestore emulator host. Optional. If the param is nil, uses the value of the emulator_host config.

  • database_id (String) (defaults to: nil) —

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

  • transport (:grpc, :rest) (defaults to: nil) —

    Which transport to use to communicate with the server. Defaults to :grpc.

  • project (String) (defaults to: nil) —

    Alias for the project_id argument. Deprecated.

  • keyfile (String) (defaults to: nil) —

    Alias for the credentials argument. Deprecated.

Returns:

Raises:

  • (ArgumentError)
