SettledTrackingMiddleware

Callable

• SettledTrackingMiddleware(request: Request, next: NormalizedFetch, metadata: MiddlewareMetadata): Promise<Response>

---

• The primary goal of this middleware is to expose a mechanism for consumers to know when all requests are completed. This is very useful for testing purposes where you may want to author tests in a higher level way (e.g. “click this button and confirm some content is updated”).

  Note: This middleware is intended to be used in non-production contexts (e.g. when debugging or running tests).

  @example

  import { fetch } from '../network';
  import { requestsCompleted } from '@data-eden/network';
  
  test('updates data when submitted', async function() {
    await render(...);
  
    await click('[some-button]');
  
    await requestsCompleted(fetch);
  
    expect(document.querySelector('.some-content').textContent).toMatchSnapshot();
  });

  Parameters

  • request: Request
