IndexedDB

This provides the IDB class, a simplified wrapper around the browser's IndexedDB API. The IDB class provides a Promise-based interface for basic database operations, abstracting away the complexity of IndexedDB's event-driven API.

The IndexedDB Wrapper consists of a single IDB class that encapsulates database connection management and basic CRUD operations. It simplifies IndexedDB usage by providing Promise-based methods instead of the native callback-based approach.

Constructor Types
constructor(dbName: string, storeName: string)

The class provides three main data operations:

addItem:creates a read-write transaction and uses the object store's add method. It returns a Promise that resolves with a success message.
getItems: fetches all items from the object store using getAll() and returns them as an array.
clearAll: removes all items from the object store using the clear() operation.

Usage Example:

Live Editor

function () {
  const indexedDB = new UtilityWrapper.IDB('test DB', 'test store');

  const item = { name: 'Test' };

  const [response, setResponse] = useState();

  const handleGetItem = async () => {
    await indexedDB.open();
    await indexedDB.addItem(item);
    const response = await indexedDB.getItems();
    setResponse(response)
  }

  return (
    <>
      <button onClick={handleGetItem}>get result: </button>
      <div>{JSON.stringify(response)}</div>
    </>
  );
}
