Ruby Client for Google Cloud Firestore API

Google Cloud Firestore API:

Quick Start

In order to use this library, you first need to go through the following steps:

  1. Select or create a Cloud Platform project.
  2. Enable the Google Cloud Firestore API.
  3. Setup Authentication.

Installation

$ gem install google-cloud-firestore

Next Steps

Example

require "google/cloud/firestore"

firestore = Google::Cloud::Firestore.new(
  project_id: "my-project",
  credentials: "/path/to/keyfile.json"
)

city = firestore.col("cities").doc("SF")
city.set({ name: "San Francisco",
           state: "CA",
           country: "USA",
           capital: false,
           population: 860000 })

firestore.transaction do |tx|
  new_population = tx.get(city).data[:population] + 1
  tx.update(city, { population: new_population })
end

Enabling Logging

To enable logging for this library, set the logger for the underlying gRPC library. The logger that you set may be a Ruby stdlib Logger as shown below, or a Google::Cloud::Logging::Logger that will write logs to Stackdriver Logging. See grpc/logconfig.rb and the gRPC spec_helper.rb for additional information.

Configuring a Ruby stdlib logger:

require "logger"

module MyLogger
  LOGGER = Logger.new $stderr, level: Logger::WARN
  def logger
    LOGGER
  end
end

# Define a gRPC module-level logger method before grpc/logconfig.rb loads.
module GRPC
  extend MyLogger
end

Supported Ruby Versions

This library is supported on Ruby 2.4+.

Google provides official support for Ruby versions that are actively supported by Ruby Core—that is, Ruby versions that are either in normal maintenance or in security maintenance, and not end of life. Currently, this means Ruby 2.4 and later. Older versions of Ruby may still work, but are unsupported and not recommended. See https://www.ruby-lang.org/en/downloads/branches/ for details about the Ruby support schedule.
