Courses App

(Optional) In case the blog post is already published, please add: Read the blog post here

This is a simple app that demonstrates how to use ConfigCat with OpenFeature in Go. The app has a REST API with a single endpoint that returns a predefined list of courses. We can enable or disable the endpoint with a feature flag in ConfigCat.

NOTE: This branch contains the complete code with OpenFeature integrated into the app. Use git checkout starter to switch to the starter branch to see the state of the app before OpenFeature was installed.
