    MDN Reference

    interface IDBObjectStore {
        autoIncrement: boolean;
        indexNames: DOMStringList;
        keyPath: string | string[] | null;
        name: string;

    Methods

    • The add() method of the IDBObjectStore interface returns an IDBRequest object, and, in a separate thread, creates a structured clone of the value, and stores the cloned value in the object store.

      MDN Reference

      Parameters

      Returns IDBRequest<IDBValidKey>

    • The clear() method of the IDBObjectStore interface creates and immediately returns an IDBRequest object, and clears this object store in a separate thread.

      MDN Reference

      Returns IDBRequest<undefined>

    • The count() method of the IDBObjectStore interface returns an IDBRequest object, and, in a separate thread, returns the total number of records that match the provided key or of records in the store.

      MDN Reference

      Parameters

      Returns IDBRequest<number>

    • The createIndex() method of the field/column defining a new data point for each database record to contain.

      MDN Reference

      Parameters

      Returns IDBIndex

    • The deleteIndex() method of the the connected database, used during a version upgrade.

      MDN Reference

      Parameters

      Returns void

    • The getAll() method of the containing all objects in the object store matching the specified parameter or all objects in the store if no parameters are given.

      MDN Reference

      Parameters

      Returns IDBRequest<any[]>

    • The getAllKeys() method of the IDBObjectStore interface returns an IDBRequest object retrieves record keys for all objects in the object store matching the specified parameter or all objects in the store if no parameters are given.

      MDN Reference

      Parameters

      Returns IDBRequest<IDBValidKey[]>

    • The index() method of the IDBObjectStore interface opens a named index in the current object store, after which it can be used to, for example, return a series of records sorted by that index using a cursor.
