Window: indexedDB property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

The indexedDB read-only property of the Window interface provides a mechanism for applications to asynchronously access the capabilities of indexed databases.

Value

An IDBFactory object.

Examples

The following code creates a request for a database to be opened asynchronously, after which the database is opened when the request's onsuccess handler is fired:

js
let db;
function openDB() {
  const DBOpenRequest = window.indexedDB.open("toDoList");
  DBOpenRequest.onsuccess = (e) => {
    db = DBOpenRequest.result;
  };
}
