Write a function to get all records from an object store.

Question

To get all records from an IndexedDB object store, you can use the
getAll() method. Here's a reusable JavaScript function that does this:
Function to Get All Records from IndexedDB Object Store
function getAllRecords(dbName, storeName) {
    return new Promise((resolve, reject) =andgt; {
        // Open the database
        const request = indexedDB.open(dbName);
        request.onerror = (event) =andgt; {
            reject(`Database error: ${event.target.errorCode}`);
        };
        request.onsuccess = (event) =andgt; {
            const db = event.target.result;
            // Open a read-only transaction
            const transaction = db.transaction([storeName], 'readonly');
            const objectStore = transaction.objectStore(storeName);
            // Use getAll() to retrieve all records
            const getAllRequest = objectStore.getAll();
            getAllRequest.onsuccess = () =andgt; {
                resolve(getAllRequest.result);
            };
            getAllRequest.onerror = (event) =andgt; {
                reject(`GetAll error: ${event.target.errorCode}`);
            };
        };
    });
}
Example Usage
getAllRecords('MyDatabase', 'MyStore')
    .then(records =andgt; {
        console.log('All records:', records);
    })
    .catch(error =andgt; {
        console.error('Error fetching records:', error);
    });
Notes
This works only if your browser supports IDBObjectStore.getAll() (most modern browsers do).If you're using a cursor-based approach (older browsers or want more control), let me know — I can provide that too.
