Angular Shopping Flags
A demo showcasing the use of feature flags in an e-commerce AngularJS app.
Built on top of Code Project's ShoppingCart, this Angular app uses LaunchDarkly feature flags to dynamically discount products in a webstore.
To integrate LaunchDarkly feature flags, we use Angular's $q to create a service which returns the feature flag client as a promise, which resolves when the client is ready to return flag variations. Then, the main store controller starts a listener. Whenever the store-discount flag is modified, the changes are detected, and new discounts are displayed to any user that may be viewing the store.
