Note: This feature is available in Web Workers.

The objectStoreNames read-only property of the IDBDatabase interface is a DOMStringList containing a list of the names of the object stores currently in the connected database.

Value

A DOMStringList containing a list of the names of the object stores currently in the connected database.

Examples

// Let us open our database
const DBOpenRequest = window.indexedDB.open("toDoList", 4);

// these two event handlers act on the database being opened successfully, or not
DBOpenRequest.onerror = (event) => {
  note.appendChild(document.createElement("li")).textContent =
    "Error loading database.";
};

DBOpenRequest.onsuccess = (event) => {
  note.appendChild(document.createElement("li")).textContent =
    "Database initialized.";

  // store the result of opening the database in the db variable. This is used a lot below
  db = DBOpenRequest.result;

  // This line will log the names of the object stores of the connected database, which should be
  // an object that looks like { ['my-store-name'] }
  console.log(db.objectStoreNames);
};
