IDBDatabase: deleteObjectStore() method

The deleteObjectStore() method of the IDBDatabase interface destroys the object store with the given name in the connected database, along with any indexes that reference it.

As with IDBDatabase.createObjectStore, this method can be called only within a versionchange transaction.

The name of the object store you want to delete. Names are case sensitive.

Exceptions

Thrown if the method was not called from a versionchange transaction callback.

TransactionInactiveError DOMException

Thrown if a request is made on a source database that doesn't exist (E.g. has been deleted or removed.)

NotFoundError DOMException

Thrown when trying to delete an object store that does not exist.

Examples

const dbName = "sampleDB";
const dbVersion = 2;
const request = indexedDB.open(dbName, dbVersion);

request.onupgradeneeded = (event) => {
  const db = request.result;
  if (event.oldVersion < 1) {
    db.createObjectStore("store1");
  }

  if (event.oldVersion < 2) {
    db.deleteObjectStore("store1");
    db.createObjectStore("store2");
  }

  // etc. for version < 3, 4…
};
