stop()

Call signature

The worker.stop() function does not accept any arguments and doesn’t return anything.

worker.stop()

Although it’s a logical opposite to worker.start(), the worker.stop() method does not unregister the worker. Instead, it instructs the worker to disable API mocking for the current client (page). This way you can have multiple open clients with the different state of the request interception.

This method is designed to be called on runtime to control the request interception flow. You do so by exposing the worker reference globally and calling window.worker.stop() in any time in the browser.

// mocks/browser.js
import { setupWorker } from 'msw/browser'
import { handlers } from './handlers'
 
export const worker = setupWorker(...handlers)
 
// Expose the worker instance globally.
window.worker = worker
