Boolean

Below is an example using isStreaming with a DefineList named todos:

var todos = Todo.getList({}).then(todos => {
  console.log(todos.value.isStreaming);
  return todos;
});

Here we are using isStreaming in a can-stache template to communicate to your users that data is still being recieved from the stream:

  {{#if todos.value.isStreaming}}
    <li style="color:#ccc">Still loading...</li>
  {{/if}}
