Prevent Duplicate Requests

One of the most common problems is the problem of sending dublicate requests at the same time. Vue.js Ajax solve it easily: preventDuplicate: true.

The following example prevents sending requests over the same URL:

Vue.ajax.get("http://example.com", {}, {
    preventDuplicate: true
});

The following example prevents sending requests over the same given key data:

Vue.ajax.get("http://example.com", {}, {
    preventDuplicate: true,
    key: "ABCDEFGH"
});
