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.
