Get started

Your first local evaluation.

Connect a supported SDK, fetch configuration, and read a flag with an explicit fallback.

1. Install the SDK

npm install <nanoflags-sdk-package>

Browser keys only access browser-safe configuration. Server keys stay on the server.

const flags = createClient({
  environment: "development",
  sdkKey: "<your-browser-key>",
});
await flags.ready();

flags.boolean("checkout-v2", false, { key: "example-user" });

If startup has no usable configuration, the documented fallback policy applies. A local result is not a network delivery acknowledgement.
