ConfigCat SDK for Ruby
https://configcat.com
ConfigCat SDK for Ruby provides easy integration for your application to ConfigCat.
ConfigCat is a feature flag and configuration management service that lets you separate releases from deployments. You can turn your features ON/OFF using ConfigCat Dashboard even after they are deployed. ConfigCat lets you target specific groups of users based on region, email or any other custom user attribute.
ConfigCat is a hosted feature flag service. Manage feature toggles across frontend, backend, mobile, desktop apps. Alternative to LaunchDarkly. Management app + feature flag SDKs.
Getting started
1. Install the package with RubyGems
gem install configcat
2. Import configcat to your application
require 'configcat'
3. Go to the ConfigCat Dashboard to get your SDK Key:

4. Create a ConfigCat client instance:
configcat_client = ConfigCat.get("#YOUR-SDK-KEY#")
We strongly recommend using the ConfigCat Client as a Singleton object in your application. The
ConfigCat.getstatic factory method constructs singleton client instances for your SDK keys.
5. Get your setting value
isMyAwesomeFeatureEnabled = configcat_client.get_value("isMyAwesomeFeatureEnabled", false)
if isMyAwesomeFeatureEnabled
do_the_new_thing
else
do_the_old_thing
end
6. Stop ConfigCat client on application exit
configcat_client.close
Getting user specific setting values with Targeting
Using this feature, you will be able to get different setting values for different users in your application by passing a User Object to the get_value() function.
Read more about Targeting here.
user = ConfigCat::User.new("#USER-IDENTIFIER#")
isMyAwesomeFeatureEnabled = configcat_client.get_value("isMyAwesomeFeatureEnabled", false, user)
if isMyAwesomeFeatureEnabled
do_the_new_thing
else
do_the_old_thing
end
Sample/Demo apps
Polling Modes
The ConfigCat SDK supports 3 different polling mechanisms to acquire the setting values from ConfigCat. After latest setting values are downloaded, they are stored in the internal cache then all requests are served from there. Read more about Polling Modes and how to use them at ConfigCat Docs.
