Examples

This is roughly what the usage of feature flags looks like once you're up and running.

// pages/index.js
import { useFlags } from "flags/client";

export default function IndexPage(props) {
  const flagBag = useFlags();

  return flagBag.flags.greeting === "dog"
    ? "Who's a good boye"
    : "Hello";
}

The self documenting examples at flags.happykit.dev show how to use @happykit/flags for client-side, static and server-side rendering.
