interface dom.IDBRequest
implements EventTarget
import { type dom } from "https://deno.land/x/evt@v2.3.1/lib/index.ts";
const { IDBRequest } = dom;

The request object does not initially contain any information about the result of the operation, but once information becomes available, an event is fired on the request, and the information becomes available through the properties of the IDBRequest instance.

Type Parameters

optional
T = any
