primeng/types/primeng-license.d.ts

PrimeNG is a premium UI library for Angular featuring a rich set of 90+ components, a theme designer, various theme alternatives such as Material, Bootstrap, Tailwind, premium templates and professional support. In addition, it integrates with PrimeBlock,

/**
 * Inject a fixed-positioned banner into the bottom-right of the page when the
 * PrimeNG license cannot be verified.
 *
 * The banner content is rendered inside a closed-mode shadow root so page-level
 * CSS cannot reach into it. `all:initial` on the host element blocks inherited
 * styles. The host carries no semantically obvious id, slowing down trivial
 * hide-by-selector attempts.
 *
 * Idempotent — guarded by the host id, so multiple call sites (the providePrimeNG
 * initializer resolving, BaseComponent detecting a failed verify) cannot produce
 * more than one banner per page.
 *
 * SSR-safe — short-circuits when `document` is undefined.
 *
 * Note: client-side license enforcement is anti-honest-user signaling, not
 * anti-piracy. The cryptographic signature (Ed25519) is what actually prevents
 * forging valid tokens. This banner just makes the licensing problem visible
 * to a legitimate customer whose key needs attention.
