What is IndexedDB and how do I use it?

IndexedDB is a low-level API for client-side storage of significant amounts of structured data, including files/blobs. It allows you to store data in a transactional database.

Can you give me an example of how to create a database using IndexedDB?

Sure! You can create a database using the following code:

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

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

How do I add data to the database?

You can add data using the add method on the object store. Here's an example:

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

What are some common use cases for IndexedDB?

Common use cases include offline web applications, storing user preferences, and caching data for faster access.
