Read data from a cart

• You've completed the quickstart guide.
• You've set up a cart handler.

Use the cart, created from createCartHandler, to get a user's cart. You don't need to provide a cart ID because it's already handled by the cart handler. cart.get() returns a promise. Use Remix's defer so that the cart data is deferred, and streamed to the browser.

You can get the content of the cart using Remix's useMatches hook, because you made it available in the root loader. Since the data is deferred, you'll need to wait for the data.
