Caution
This demo is using the GO Feature Flag module directly. We recommend to use OpenFeature instead for a better integration with different technologies.
This repository contains a demo app using the library thomaspoignant/go-feature-flag which display a webapp containing a grid of users.
Each square is a different user and can be change by modifying the feature flag color-box.
With this demo app you can modify your flag and visually see which users are impacted by the change.

In this example we can see how randomly the flag apply to only a percentage of the users.
The app use labstack/echo as a http server and serve an HTML page with one square per user.
Every square has his own UUID to represent a user, it means that you play with you flag and directly see which user will be impacted.
To build the app you have to run these command:
go mod tidy && go mod vendor # to retrieve dependencies
go build .
./demoIf you have any issue with this demo app you can open an issue.
