useApp

Retrieve the current Vue application, its global properties, and Runable hooks.

function useApp(): AppContext

const app = useApp();

app.$router;
app.$route;
app.config.globalProperties;

Call useApp() from setup(), a composable, or after installing the context plugin. The function throws when no current or global application is available.

During SSR, do not keep this result in a module variable: the application must remain isolated per request.
