WorkerGlobalScope: indexedDB property

{{APIRef("IndexedDB")}}{{AvailableInWorkers("worker")}}

The indexedDB read-only property of the {{domxref("WorkerGlobalScope")}} interface provides a mechanism for workers to asynchronously access the capabilities of indexed databases.

Value

An {{domxref("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;
  };
}
