Disposal

Problem

A route can end while requests and streams are active, but the application client must remain usable elsewhere.

Solution

Use cancelAll() for a reusable scope and dispose() only at the final application or request boundary.

import { createCourier } from '@vielzeug/courier';

const courier = createCourier({ baseUrl: 'https://api.example.com' });

function leaveRoute(): void {
  courier.cancelAll();
}

function shutdownApplication(): void {
  courier.dispose();
}

Pitfalls

• A disposed client cannot start requests or streams.
• Create clients per application or SSR request scope, not per component render.
• Unsubscribe cache listeners when their view or route ends; it does not dispose client.
