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.

Note: This feature is only available in Web Workers.

The indexedDB read-only property of the WorkerGlobalScope interface provides a mechanism for workers 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:

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