How can I use IndexedDB in my web application?

IndexedDB is a low-level API for client-side storage of significant amounts of structured data, including files/blobs. You can use it to store data in a web application.

What are the main features of IndexedDB?

IndexedDB allows you to store large amounts of data, supports transactions, and provides a rich query interface. It's asynchronous, which helps keep your app responsive.

Can you show me a simple example of how to create a database?

Sure! Here's a basic example:

let request = indexedDB.open('myDatabase', 1);

request.onupgradeneeded = function(event) {
    let db = event.target.result;
    db.createObjectStore('myStore', { keyPath: 'id' });
};

request.onsuccess = function(event) {
    console.log('Database created successfully!');
};

This code opens a database and creates an object store.

How do I add data to the database?

You can add data using a transaction. Here's an example:

let transaction = db.transaction(['myStore'], 'readwrite');
let store = transaction.objectStore('myStore');
store.add({ id: 1, name: 'Item 1' });
