Should you use IndexedDB in 2026?
Chrome, Firefox, Opera and IE10 have shipped it. Safari started to support it in iOS8.
The IndexedDB Polyfill is a polyfill for the IndexedDB APIs over WebSql. This enables IndexedDB to work on browsers that support WebSql. IDBWrapper helps smooth out the cross-browser differences. You may consider falling back to WebSQL when IndexedDB isn't available, but do keep in mind that WebSQL has been abandoned.
How to use it
const req = indexedDB.open('app', 1);
req.onupgradeneeded = () => req.result.createObjectStore('notes', { keyPath: 'id' });
req.onsuccess = () => {
const tx = req.result.transaction('notes', 'readwrite');
tx.objectStore('notes').put({ id: 1, text: 'hello' });
};
