JavaScript Browser Demo of Unlaunch Feature Flags

This is a sample project showing how to use Unlaunch JavaScript Library in your HTML apps and pages.

How to use

1. Clone the project.
2. Open login.html in your browser. In this example, we are using a feature flag to determine whether to show old (v1) or the new (v2) version of the login form. If the flag is evaluated as on, it will show Login V2. Otherwise, it will show Login V1. The flag is set to show on variation 50% of the time.
3. View the source code of login.html to see how Unlaunch client is being initialized and the feature flag is evaluated.

There's also login-non-sticky.html which does not use local storage to persist evaluated result and calls the backend each time the page is refreshed with a random identity to evaluate the flag.

• Unlaunch JavaScript Library Source Code on GitHub
