IDBFactory: deleteDatabase() method

Syntax

// For the current standard:
deleteDatabase(name)

// For the experimental version with `options` (see below):
deleteDatabase(name)
deleteDatabase(name, options)

Parameters

name

The name of the database you want to delete. Note that attempting to delete a database that doesn't exist does not throw an exception, in contrast to IDBDatabase.deleteObjectStore(), which does throw an exception if the named object store does not exist.

options Optional

In Gecko, since version 26, you can include a non-standard optional storage parameter that specifies whether you want to delete a permanent (the default value) IndexedDB, or an indexedDB in temporary storage (aka shared pool.)

Return value

An IDBOpenDBRequest on which subsequent events related to this request are fired.

If the operation is successful, the value of the request's result property is null.

Examples

const DBDeleteRequest = window.indexedDB.deleteDatabase("toDoList");

DBDeleteRequest.onerror = (event) => {
  console.error("Error deleting database.");
};

DBDeleteRequest.onsuccess = (event) => {
  console.log("Database deleted successfully");

  console.log(event.result); // should be undefined
};
