This guide shows you how to read a user's cart.

## Requirements

- You've completed the [quickstart guide](/docs/storefronts/headless/hydrogen/getting-started).
- You've [set up a cart handler](/docs/storefronts/headless/hydrogen/cart/setup).

## Step 1: Get a visitor's cart

Use the `cart`, created from [`createCartHandler`](/docs/api/hydrogen/latest/utilities/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](https://remix.run/docs/en/main/utils/defer) so that the cart data is deferred, and [streamed to the browser](https://remix.run/docs/en/1.17.1/guides/streaming#streaming).

<script type="text/plain" data-language="jsx" data-title="JavaScript" data-filename="/app/root.jsx">
RAW_MD_CONTENT
export async function loader({context}) {
  const {cart} = context;

  return defer({
    cart: cart.get(),
  });
}
END_RAW_MD_CONTENT</script>
<script type="text/plain" data-language="jsx" data-title="TypeScript" data-filename="/app/root.tsx">
RAW_MD_CONTENT
export async function loader({context}: LoaderArgs) {
  const {cart} = context;

  return defer({
    cart: cart.get(),
  });
}
END_RAW_MD_CONTENT</script>

</div>
</p>


## Step 2: Server render the content of the cart

You can get the content of the cart using Remix's [`useMatches`](https://remix.run/docs/en/main/hooks/use-matches) hook, because you made it available in the root loader. Since the data is deferred, you'll need to wait for the data.
