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: {},
  data: null,
  error: "response-not-ok",
  fetching: false,
  settled: true,
  visitorKey: "snhj42bSJZkvc9cOuLuyZ"
}

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