Deleting data from object stores

Similar to writing and reading, we can also delete data from the object store, as well, as follows:

const open = window.indexedDB.open("types", 1); // same database as aboveopen.onsuccess = () => {    const dbHandler = open.result;    const transaction = dbHandler.transaction(['frontend'], 'readwrite');    const storeHandler = transaction.objectStore('frontend');    storeHandler.delete("HTML5");};

The only thing we did here was using the delete method. Note that we have to give the readwrite access to the transaction in order to delete the record.

It's recommended that you go through MDN documents to get a deeper insight on how to make indexedDB work in big projects; you can find them at https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API/Using_IndexedDB ...
