Targeting by User

This demo is easiest to understand if you open its source code in a parallel tab.

Source code

This demo shows how to use @happykit/flags for targeting users.

HappyKit allows you to do pass in a user. You can use that user and the provided uesr profile for rules or percentage-based rollouts. The fields supported in the user profile are defined in the README and in the TypeScript types.

Render #1 (Current render)
{
  flags: {
    ads: true,
    checkout: "short",
    discount: 5,
    purchaseButtonLabel: "Purchase"
  },
  data: {
    flags: {
      ads: true,
      checkout: "short",
      discount: 5,
      purchaseButtonLabel: "Purchase"
    },
    resolvedVariantIds: {
      ads: "on",
      checkout: "on",
      discount: "on",
      purchaseButtonLabel: "on"
    },
    visitor: {
      key: "fiffKwNrw08LK1nlAUUxs"
    }
  },
  error: null,
  fetching: false,
  settled: true,
  visitorKey: "fiffKwNrw08LK1nlAUUxs"
}

Note that aside from users, HappyKit also has the concepts of a visitor and traits. These three concepts are all independent of each other.
