Request cookies

You can read the request’s cookies via the cookies object provided to you in the response resolver argument. While you can always read the request.headers.get('cookie') manually, the cookie object parses request cookies for you for convenience.

http.get('/api/user', ({ cookies }) => {
  if (!cookies.authToken) {
    return new HttpResponse(null, { status: 403 })
  }
 
  return HttpResponse.json({ name: 'John' })
})

MSW uses a third-party cookie parsing package that parses cookies per the HTTP Cookie specification.
