import { createEntitlements } from "@sweberdev/integral";
import { Feature, IntegralProvider, Limit, useFeature } from "@sweberdev/integral-react";

const entitlements = createEntitlements({ plans, license });

<IntegralProvider entitlements={entitlements}>
  <App />
</IntegralProvider>;

Feature

<Feature name="export" fallback={<UpgradeHint />}>
  <ExportButton />
</Feature>

name can be an array; then all features are required.

Limit

<Limit name="projects" used={projects.length} fallback={(c) => <p>{c.limit} projects is the limit of your plan.</p>}>
  <NewProjectButton />
</Limit>

Children and fallback can be render functions that receive { limit, used, remaining, allowed }.

Hooks

• useEntitlements() returns the entitlements object.
• useFeature("export") returns a boolean.
• useLimit("projects", used, amount?) returns the limit check.
• useLicenseCheck(check, key) runs an async check (for example Polar validation wrapped in withOfflineGrace) whenever key changes, and returns status (idle, loading, valid, invalid, error), result and refresh(). Pass null as key to skip.

const { status } = useLicenseCheck((key) => checkWithGrace(key), licenseKey || null);

Hide features in the UI for convenience, but enforce them where it matters: on your server for paid APIs, or in the code path itself for desktop apps.
