Experiment Ruby SDK
Amplitude Ruby Server SDK for Experiment.
Installation
Into Gemfile from rubygems.org:
gem 'amplitude-experiment'
Into environment gems from rubygems.org:
gem install 'amplitude-experiment'
To install beta versions:
gem install amplitude-experiment --pre
Remote Evaluation Quick Start
require 'amplitude-experiment'
# (1) Get your deployment's API key
apiKey = 'YOUR-API-KEY'
# (2) Initialize the experiment client
experiment = AmplitudeExperiment.initialize_remote(api_key)
# (3) Fetch variants for a user
user = AmplitudeExperiment::User.new(user_id: '[email protected]', device_id: 'abcezas123', user_properties: {'premium' => true})
# (4) Lookup a flag's variant
#
# To fetch asynchronous
experiment.fetch_async(user) do |_, variants|
variant = variants['YOUR-FLAG-KEY']
unless variant.nil?
if variant.value == 'on'
# Flag is on
else
# Flag is off
end
end
end
# To fetch synchronous
variants = experiment.fetch(user)
variant = variants['YOUR-FLAG-KEY']
unless variant.nil?
if variant.value == 'on'
# Flag is on
else
# Flag is off
end
end
Local Evaluation Quick Start
require 'amplitude-experiment'
# (1) Get your deployment's API key
apiKey = 'YOUR-API-KEY'
# (2) Initialize the experiment client
experiment = AmplitudeExperiment.initialize_local(api_key)
# (3) Start the local evaluation client
experiment.start
# (4) Evaluate a user
user = AmplitudeExperiment::User.new(user_id: '[email protected]', device_id: 'abcezas123', user_properties: {'premium' => true})
variants = experiment.evaluate(user)
variant = variants['YOUR-FLAG-KEY']
unless variant.nil?
if variant.value == 'on'
# Flag is on
else
# Flag is off
end
end
