connection.parseListData(responseData)

Parameters
- responseData
{Object}:The response data from the AJAX request.
Use
parseListData comes in handy when dealing with an irregular API
that can be improved with data transformation.
Suppose an endpoint responds with a status of 200 OK, even when the request generates an empty result set. Worse yet, instead of representing an emtpy set with an empty list, it removes the property.
A request to /services/todos may return:
{
todos: [
{todo: {id: 0, name: "dishes"}},
{todo: {id: 2, name: "lawn"}}
]
}
What if a request for /services/todos?filterName=bank responds with
200 OK:
{
}
This response breaks its own schema. One way to bring it in line with a format compatible with ListData is:
connect([
require("can-connect/data/parse/parse"),
require("can-connect/data/url/url")
],{
parseListProp: "todos",
parseListData(responseData) {
if (responseData && !responseData.todos) {
responseData = { todos: [] };
}
return responseData;
}
})
