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.
``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.
`sh`
$ ws --mocks example-mocks.js
Serving at http://mbp.local:8000, http://127.0.0.1:8000, http://192.168.0.100:8000
GET your rivers.
`sh`
$ curl http://127.0.0.1:8000/rivers
[
{
"name": "Volga",
"drainsInto": "Caspian Sea"
},
{
"name": "Danube",
"drainsInto": "Black Sea"
},
{
"name": "Ural",
"drainsInto": "Caspian Sea"
},
{
"name": "Dnieper",
"drainsInto": "Black Sea"
}
]
