The CMP boots **once** on the initial page load and persists across client-side navigations — you don't re-run `init()` on every route change. The banner, the stored decision, and every [bridge](/integrations/bridges/) stay live for the lifetime of the app session. - Install the [Quickstart](/quickstart/) snippet in your app shell / document ``, exactly as for a static site. - Read consent anywhere in app code via `LightningCMP.getConsent()` and react to changes with `LightningCMP.onConsentChange(fn)` — see the [JavaScript API](/api/javascript-api/). - Open preferences from your own UI (e.g. a settings screen) with `LightningCMP.openPreferences()`. :::note[More detail coming] Framework-specific SPA notes are being migrated from `docs/INSTALL.md` § _“Single-page apps & route changes.”_ :::
