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. You can use it to store data in your web app, allowing for offline capabilities and faster access.

What are the main advantages of using IndexedDB over localStorage?

IndexedDB supports larger amounts of data, complex queries, and transactions, while localStorage is limited to string data and has a smaller storage limit.

Can you provide a simple example of how to create a database using IndexedDB?

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 handle errors when working with IndexedDB?

You can handle errors by using the onerror event handler on your requests. For example:

request.onerror = function(event) {
    console.error('Database error: ' + event.target.errorCode);
};
