README

This code repo contains no business logic, only serves as a demo to integrate split.io Ruby SDK with Rails.

How to run this project on your computer

Ruby, here I use version 2.7.5 for an example (can install via a Ruby version manager, recommend asdf)
Httpie for CLI testing (feel free to use cURL / Postman)
run bundle install to install Ruby dependencies (split.io Ruby SDK already included)

run SPLIT_IO_API_KEY=xxx rails s in command line to start a web server process on your computer, replace xxx with your server-side split.io API key
run SPLIT_IO_API_KEY=xxx rails c in command line to start a Rails console process on your computer, replace xxx with your server-side split.io API key

In command line interface, run http localhost:3030 to check if the server is running, expecting response { "ok": true}

on split.io dashboard, create a split named test_global_feature_flag, traffic type can be global or account
define treatment on and off, configure the Set the default rule to serve off
run http 'localhost:3030/test_global_feature_flag' in command line, response should be {"ok": true, "status": "off"}
In Rails console, run SPLIT_CLIENT.get_treatment('global', 'test_global_feature_flag'), result should be off
on split.io dashboard, change default rule of split test_global_feature_flag from off to on
run http 'localhost:3030/test_global_feature_flag' in command line, response should be {"ok": true, "status": "on"}
In Rails console, run SPLIT_CLIENT.get_treatment('global', 'test_global_feature_flag'), expected result is on, actual result is off. SDK data is not syned!

In Rails console, after running Rails.configuration.split_factory.resume!, it seems the SDK in Rails console process starts to sync data with split.io web service.
