Server Components

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 server components in Next.js App Router.

Since this page is rendered on the server only, there is no flagBag. Instead, the values are shown directly.

Flags
{
  flags: {
    ads: true,
    checkout: "short",
    discount: 5,
    purchaseButtonLabel: "Purchase"
  },

    flags: {
      ads: true,
      checkout: "short",

    resolvedVariantIds: {
      ads: "on",
      checkout: "on",
      discount: "on",
      purchaseButtonLabel: "on"
