lws-mock-response

Middleware adding mock responses to lws.

Imagine the network is down or you're working offline, proxied requests to https://internal-service.local/api/users/1 would fail. In this case, Mock Responses can fill the gap. Mocks are defined in a module which can be reused between projects.

Trivial example - respond to a request for /rivers with some JSON. Save the following Javascript in a file named example-mocks.js.

class MockRivers {
  mocks () {
    return {
      route: '/rivers',
      responses: [
        {
          response: {
            type: 'json',
            body: [
              { name: 'Volga', drainsInto: 'Caspian Sea' },
              { name: 'Danube', drainsInto: 'Black Sea' },
              { name: 'Ural', drainsInto: 'Caspian Sea' },
              { name: 'Dnieper', drainsInto: 'Black Sea' }
            ]
          }
        }
      ]
    }
  }
}

Launch ws passing in your mocks module.

$ ws --mocks example-mocks.js

  {

  },
  {
    "name": "Ural",
    "drainsInto": "Caspian Sea"
  },
  {

    "drainsInto": "Black Sea"
